Application, Operating Conditions and Construction
Manufacturer's Notification
CAKE compact units are manufactured in accordance with valid
Czech and European regulations and technical standards. ese
units must be installed and used only in accordance with this do-
cumentation. e installation and operating documentation must
be available to the operating and servicing staff, and it is advisable
to store this documentation close to the installed air-handling unit.
Application and Operating Conditions
CAKE compact units are designed for the ventilation and air-
-conditioning of building interiors, especially commercial facilities
with low air flow rates of approx. 500 to 3,000 m3/h (e.g., small
commercial premises, offices, restaurants and schools). ey are
designed to transport air without solid, fibrous, sticky, aggressive,
respectively explosive impurities. e inlet air must be drawn from
a hygienically wholesome environment. If not stated otherwise,
the transported air must be free of chemicals or chemicals corro-
sive to metal or aggressive zinc and aluminium.
CAKE compact air-handling units can be used in normal rooms
(IEC 60364-5-51, resp. ČSN 33 2000-5-51 ed. 3, ČSN 33 2000-
1 ed. 2) and in rooms with an extended ambient temperature
range ranging from -20 to +40°C without additional measures,
respectively -40°C to +55°C (customization). When designing the
air-handling assembly lay-out, it is necessary to take into account
the temperature and humidity of the inlet and outlet air in rela-
tion to the ambient temperature and humidity. is is especially
important for sufficient ventilation of the air-handling plant. For
outdoor installations where excessively humid air is exhausted
from the room (e.g., applications with a humidifier or other source
of humidity), it is necessary to consult this environment with the
manufacturer (for additional installation of a condensate drainage
tray inside the device). Failure to meet these conditions will result
in excessive condensation (misting and leaking) and possible
freezing. If the device is designed for outdoor environments (out-
door version), it is advisable to protect it with a roof. Degree of
protection against foreign matters and water is IP 44. e unit's
accessories (M&C) are not included – they must be assessed
separately according to their documentation.
CAKE compact air-handling units are designed to be installed on
the floor or a supporting structure. CAKE compact air-handling
units can be connected to a 1x230V+N+PE /50Hz or 3x400V+-
N+PE/50Hz powersupply system (dependingon themotortype).
The unit's operation is possible only with a measuring and
control system, ensuring control and safety functions. e main
precondition is the installation of functional antifreeze protection
elements of heat-exchangers, plate or rotary heat exchangers,
including active protection of the unit when reaching the final
pressure loss of filters.
is device must not be used (operated) by young (children, etc.)
or disabled persons.
Air-Handling unit Construction
is air-handling unit is designed as a panel and compact system.
All the panels are of sandwich construction with a total thickness
of 50 mm, and are made of hot–dip galvanized sheet steel in
accordance with ČSN EN 10 346 Z275 g/m2with basic corrosion
resistance for the C2 environment class in accordance with ČSN
EN ISO 14713. Alternatively, the panels can be provided with
additional surface finish:
Continuous polyester paint 25 μm, RAL 9002 ČSN
EN10169, corrosion resistance for the C3 environment class in
accordance with ČSN EN ISO 14713
Powder polyester paint 60 μm, RAL 9002 ČSN EN10169,
corrosion resistance for the C3 environment class in accordan-
ce with ČSN EN ISO 14713
Powder EP/PES paint, min. 60 μm, RAL 3020 ČSN
EN10169, corrosion resistance for environments with a higher
content of chloramine (swimming pools). Insulation of the pa-
nels is created by 50mm thick non-combustible mineral wool,
50 kg/m2.
e fixed panels are attached with screw joints – the
M6x20 metric Allen screws or alternatively the 4,2x16 self-
-tapping hexagon-head screws (DIN 7504-K) and plugs. To
install and remove the panels attached with metric screws, it
is necessary to use an Allen wrench, size 5 and for the panels
attached with self-tapping screws, it is recommended to use
a magnetic screwdriver inner hexagon bit, size 7 (BN 31522,
length 75 mm).
e panels, which are supposed to be regularly used to
access the internal assemblies in order to perform checks,
periodic maintenance, service operations or unit cleaning, have
doors equipped with rotary safety closures.
e contact surfaces of the panels are fitted with the 12x3
self-adhesive PE sealing, temperature resistance from -40 °C to
+80 °C and rate of volume absorption below 5%. e contact
surfaces of the doors are fitted with the moisture-resisting EPDM
sealing, temperature resistance from -40 °C to +80 °C. e per-
manent joints are sealed with non-silicone sealant of temperature
resistance from -40 °C to +90 °C.
If the compact unit includes an integrated control unit, the
access to the switchboard box is ensured through the inspection
door from the service side. is door can be opened using a special
tool (Triangular 8). e box degree of protection is IP44.
e complete CAKE compact air-handling unit is manufactured as
a compact block, delivered in separate sub-blocks designed to be

Air-handling Unit Safety
Personnel Protection Measures:
Protection against Dangerous with Non-Live Parts
e protection against dangerous contact with non-live parts
is performed by mechanical connections ensuring electrical
conductivity or by interconnection with a protective conductor
(PE) in accordance with ČSN EN 60204-1 ed.2.
Protection against Dangerous with Live Parts
To connect the grounding, a
groundconnection point isprepa-
red on the base frame on which a
lightning conductor clampcanbe
connected. Another grounding
connection point is situated on
the upper casing of the unit. e
entire unit is conductively inter-
connected so there is no need
for additional interconnection.
Protection is ensured as follows:
Integrated removable covers (motor drives, measuring and
control elements and terminal boxes) which can only be re-
moved using tools and internal parts accessible only using the
service doors of the compact air-handling unit.
By door of the sheet metal switchboard box (this box serves
to place electrical equipment inside the air-handling unit) can
only be unlocked using a special tool and are accessible from
the service side, degree of protection IP44 (ČSN EN 60529-1).
Protection of the frequency inverters situated inside the air-han-
dling unit against dangerous contact of live parts is ensured by
the degree of protection IP20 of the built-in devices in accordance
with ČSN EN 60529.
Staff qualification requirements
Installation, connection, commissioning, repairs and maintenance
can only be performed by properly qualified personnel. Electrical
wiring, interconnection of individual parts, initial inspection, ope-
ration and maintenance must be performed in accordance with
applicable standards and regulations. e user is responsible for
device use in accordance with applicable standards.
Working on Air-handling Unit
When performing any work, repairs, maintenance or cleaning,
the device must always be safely disconnected from the power
supply. When planning or installing the air-handling unit, observe
normative requirements for safe access to the air-handling
unit. When reinstalling the covers also restore their conductive
connections (properly tighten the screws using fan washers or
interconnectthem bythe groundingwire).Maintain theprescribed
degree of protection..
Installation
Location
e surface of the site for the air-handling unit installation must be
level and flat. Maximum misalignment of the floor or supporting
structure intended for the compact air-handling unit installation
must not exceed 1 mm per 1 meter. To eliminate floor slope or
other floor inequalities, the adjustable feet must be used (for
adjustment, refer to the chapter "Adjustable and Fixed Feet").
Observance of this condition is important for installation as well as
for the air-handling unit operation. e CAKE compact air-handling
unit does not need any special anchoring. To eliminate possible
vibrations, it is advisable to put grooved rubber stripes under
the air-handling unit. It is recommended to place the compact
air-handling unit so that the gap between the unit and wall will
be at least 50 mm (to eliminate growth of mould on the walls).
Pay extra attention, if it is necessary to place the air- handling
unit close to combustible materials. In this case it must always
be assessed maximum temperature of the unit's casing and flash
point of the combustible material.
Service Access
When planning the air-handling unit location, it is necessary to
keep sufficient space for maintenance, service and operating.
It is essential to ensure sufficient space for opening the doors,
removing all filtration inserts, full extension of all heat-exchangers,
including heat recovery heat-exchangers.

safety closures. When the door handle is moved down, the safety
closure keeps the doors just ajar. To fully open the door, the door
handle must be moved back to the horizontal position. en the
door is released. To close the door, proceed in the reverse order of
steps. Each door is equipped with one lockable closer.
Figure 4 – Safety door lock
Pre-installation Inspection
Prior to installation, the following must be checked:
Intactness of the delivery (completeness according to the
bill of delivery)
Volubility of rotary components (fans, dampers, rotary heat
exchanger)
Parameters of the power supply and connected energy
media sources. Any fault must be removed before starting the
installation.
Identification of Air-handling Unit Components
The association to the particular purchase order number is
indicated on the name plate of the CAKE compact air-handling
unit or of each block (if the unit is delivered disassembled), i.e. the
device number or block position number. e name plate is visibly
situated on the service side of the unit.
Base Frame
e base frame’s adjustable feet are protected by corner covers
intended only for the transport and handling of the unit. ere
covers should be removed aer installation.
Assembly of Air-handling Unit Sections
e basic version of the compact air-handling unit is delivered
assembled. If the compact air-handling unit is delivered disassem-
bled, the individual parts of the unit are assembled on the site,
i.e., the base frames are connected first and then the blocks are
connected together. For the recommended installation procedure
of the frame adjustable or fixed legs, refer to the appendix to this
document. e centre block of the disassembled unit is delivered
including the base frame and other parts of the compact air-hand-
ling unit are delivered with the base frames and block separated,

Installation, Connection of Heat Exchangers
Rotary Heat Exchanger
A rotary heat exchanger is oneof the most expensive components
in the air-handling assembly; poor and/or incorrect installation can
result in costly repairs. During improper handling, transport or if
the installation conditions are not met, the heat-exchanger rotor
can be misaligned or permanently damaged. To enable service or
cleaning of the rotor, it is necessary to ensure sufficient free space
in front of the unit so that the rotary heat exchanger can be fully
extended from the unit.
Media Connection, Condensate Drainage
and Air-handling Duct Connection
Connection of Heating and Cooling Media Feeds
e heating and cooling water feeds are connected to the outer
side of the air-handling unit. e internal interconnection is made
during production in the factory. External outlets are terminated
with external threaded connections. e heat exchangers are
counter-current connected to achieve maximum output.
e heat exchangers are not equipped with air-venting valves.
erefore, the inlet and outlet line venting must be vented during
installation – at the highest points.
Connection of direct evaporators is carried out by routing the
piping into the air-handling unit through rubber grommets in the
casing and connecting it to the cooler necks. Direct evaporators
must be connected by a specialized contractor authorized to
install refrigerating equipment. e direct evaporators are filled
with nitrogen in the factory. e water heat exchanger connec-
Figure 11 – Connection of heat-exchangers (cap nuts)
tions must cause no mechanical stress. Forces arising from the
dilatation and weight of feeding pipes and fittings must not be
transferred to the air-handling unit.
e corresponding connection points are marked with labels
on the unit side panel (heating water inlet, heating water outlet,
coolant inlet, coolant outlet).
Aer connecting the water heat exchangers (heaters and coolers,
including mixing sets) to the distributing piping, it is necessary to
pressurize (flush with water) and vent the entire circuit, including
the heat exchanger. en it is necessary to perform leak-tightness
checks of all pipe joints and of the exchanger itself (including
inspection of the unit interior with the water heat exchanger).
e manufacturer does not provide any guarantee covering
any damage resulting from liquid leakage from leaky joints or a
damaged exchanger, except the internal interconnection which
was carried out by the manufacturer.

Steam Humidification
Steam humidification is only delivered as an accessory. Steam
humidification is installed into the inlet air duct line. Air ducts lea-
ding through cold areas must be insulated to avoid condensation.
e entire humidification assembly (steam generators, including
steam distribution piping) should be situated in a non-freezing
room. Otherwise, anti-freeze protection must be installed.
e following minimum distances (distances between the steam
humidifier and the following air-handling unit components, where
H representsthe minimumevaporatingdistance calculatedfor the
given conditions) must be observed to ensure proper operation
of the steam humidifier:
Humidistat piping, humidity sensor, temp. sensor: 5x H
Very fine filter: 2.5 x H
Heating elements, filter: 1.5 x H
Duct branch piece, duct elbow, air outlet, fan: 1x H
Notes:
e steam generator can be noisy (switching of solenoid valves);
therefore, it is advisable to install it away from quiet areas. 100°C
hot and heavily mineralized water is drained from the steam
humidifier. If the H value is not known, it is advisable to make the
calculation with a minimum value of 1.0 m.
Condensate Drainage
Stainless trays for collection of the condensate are installed inside
the compact air-handling unit in places where condensation is
expected. e tray outlet is routed through the lower panel and
terminatedwith aneckand theDN40connection.e condensate
drainage system is connected to this outlet.
econdensate drainagekitsareavailable asoptional accessories.
A separate condensate drainage kit must be used for each indivi-
dual block. e siphon height depends on the total pressure of the
fan, and ensures its proper functioning. e type of condensate
Figure 12 – Condensate draining
draining kit must be designed in the course of the air-handling
unit calculation. e standard CAKE unit condensate drainage is
always in negative pressure.
e correct installation and correct minimum level heights have
crucial influence on the correct and reliable condensate drainage
from the unit. e condensate draining piping must end in free
atmosphere, i.e. it must not end directly in the closed sewerage
system.
Before operating the air-handling unit or aer being out of ope-
ration for a longer period, it is necessary to fill the siphon in each
tray with min. 0.5l of water.
If there is a risk of freezing, it is necessary to insulate the siphon and
condensate draining piping, respectively keep the ambient tem-
perature above freezing point, e.g. with an electric heating cable.
If the outdoor version of the unit is specified in the order and
includes the manufacturer's control system, the delivery includes
a heating cable.
Air-handling Duct Connection
e air ducting must be connected to the air-handling unit via an
elastic element to avoid the transfer of vibrations. e connection
of the air-handlingducting mustbe performed so thatnoload from
the air duct will be transferred to the inlet panel of the air-handling
unit. e accessories must be installed in accordance with the
air-handling unit specification and the Installation Instructions of
the manufacturers of such accessories.
No connections, including insulation and associated structures,
must prevent opening of the air-handling unit and control unit
doors, but they must allow access to the media connections
(electric connections, cooling and heating water supply and
output) and must not limit the service room needed for proper
operation and maintenance. If the compact air-handling unit is
delivered disassembled, the internal cable interconnection is
made using connectors. ese connectors must be connected
when the individual unit blocks are assembled.

the manufacturer, i.e., connected to the control unit inside the
switchboard box where all the connecting terminals are also
situated.
If the compact unit includes an external control unit which is
a part of the delivery, the entire internal wiring is prepared and
connected to the prepared connecting terminals in the terminal
box inside the unit. All the connections between the control unit
and internal M&C elements are performed through the com-
mon grommet and terminal inside the terminal box.
If the control system is not included in the specification of
the CAKE compact unit order, only internal protective interco-
nnections are performed and all the internal wiring, including
M&C elements, will be performed on the site.
Wiring of External M&C Elements
External measuring and control elements, not firmly attached
to the air-handling unit, are installed on site and connected to:
a prepared terminal box on the top of the unit casing (CAKE
version with an integrated control unit);
a terminal box (CAKE version with an external control unit
included in the delivery)
Main Supply Cable Connection
If the device is equipped with the integrated control unit, the
supply cable is connected to the main terminal box situated on
the top of the compact air-handling unit casing.
If an external control unit is used, the supply cable is conne-
cted to the terminal of the main switch situated in the control
unit.
e wiring and installation of the M&C system’s external au-
xiliary elements must be performed by qualified professionals
authorized to perform wiring of the given type of device. e
wiring must be performed in accordance with the directives
and standards of the country of installation, and in accordance
with the Installation and Operating Instructions of individual
pieces of equipment (frequency converters, pressure and
temperature sensors, etc.). Conformity of the power supply
voltage, frequency and protection with the data in the technical
documentation and on the type plate of the connected device
and cross-section of the connecting cables must be checked
before connecting the electrical equipment to the power supp-
ly. Before putting the air-handling unit into operation, a wiring
inspection must be performed.

Wiring
Sheet Metal Switchboard Box
is box is intended for installation of electrical elements. It is
integrated into the interior of the compact air-handling unit
and accessible through the door on the service side. e door is
equipped with a safety closure opened by a triangular key no. 8
which must be stored on a dedicated place under supervision of
a responsible person.
Instructions for Cabling
All interconnections of the distribution board and installed
elements must be made using intact double insulated cables
which must be properly dimensioned for the given load and
lead length.
Every cable leading out through the sheet metal parts must
be led through the preinstalled cable grommets. All unused gro-
mmets must be blinded to maintain the degree of protection.
e main power supply cable harness must be dimensioned
for the total current of the unit.
A central sheet metal cable trough with outlets fitted with
grommets is installed along the rear wall to ensure safe leading
of the cables.
When connecting and leading the cables, it is necessary to
take into account their properties. e conductors must not be
exposed to strains which decrease their service life. Avoid cable
slack;
Always use cable protectors and troughs (wire, plastic, or
metal) of sufficient size and length.
WAGO screw-free terminals are used to connect the con-
ductors. If stranded conductors are used, it is recommended to
provide their insinuated ends with cable tubes.
Properly fix all cables and maintain minimum bending radi-
uses.
e M&C cable lines must be led separately from the power
cables to avoid their interference. We recommend running the
power cable lines along the base frame and the M&C cable
lines along the front edge of the top panel.
e cable lines must never interfere with the service panels
(doors) of the unit and control unit and obstruct routine operati-
on and servicing. Please respect the reserved servicing space.

Control Unit and Control Unit Communication
A separate manual is provided for the control unit.
EC motors
e fans used in the unit are equipped with EC motors.
If the control unit (internal or external) is delivered along
with the unit, the motors have already been connected in the
factory.
If access to the motor terminal box is needed, it is necessa-
ry to pull out the entire fan from its position.
Rated voltage 1x230 V AC 50 Hz for outputs up to 1.3 kW.
Rated voltage 3x400 V AC 50 Hz for outputs above 1.3
kW and up to 6 kW. As standard, they are designed for frequen-
cy 50 Hz. A motor can optionally be delivered for a frequency of
60 Hz.
Installed EC motors are equipped with automatic heat,
electronics and overload protections.
Note: If you are considering connecting the air-handling unit
to a 60 Hz power supply system, it is necessary to check
whether the parameters of the air-handling unit have been
designed for this frequency.
To pull out the fan:
Loosen the side screws on the front clamping bar of the
base.
Remove the released clamping bar.
Pulling the base plate towards you pull the fan out of its
seat.
When inserting the fan back, follow the steps above in re-
verse order.
If the protective interconnections have been disconnected,
reconnect them.
Air Flow Control
If the delivery includes an air flow control sensor, it is fitted inside
the unit. As an option, preparation for non Remak sensor installa-
tion inside the unit is offered. Holes in the doors are prepared
for its connection. Depending on the type of operating pressure
or volume, an air-flow rate
sensor can be used.
e sensor's inputs are
connected to two hose lines
Line (+) is terminated at the
sensing terminal in the inlet
while the sensing line (-) is,
terminated in the fan
diffuser under the impeller
e sensor must be properly
set to ensure the correct
conversion of the measured
pressure to the air flow.
is is performed using a spe-
cific factor (constant) which is
dependent on the impeller
size (see the table).

Commissioning Preparation and Commissioning
Settings are made in the device or in the control unit, depending
on the type of device. To increase sensing accuracy, a range of
the measured pressure is set in the device. e required setting
values are specified in the technical documentation delivered
with each device.
Rotary Regenerator
As standard, the rotary regenerator can be delivered with two
types of drives:
A step motor controlled by the control unit
An asynchronous motor 400V/50Hz controlled by the fre-
quency inverter
If the delivery includes a frequency inverter to control output
of the rotary regenerator, the electric connection (input) is 1 x
230V/50Hz (and output for the motor is 3 x 230V ∆).
Main Switch
If the compact air-han-
dling unit includes the
integrated control unit, it
is equipped with the main
switch (the red handle in
the yellow field) on the
service side.
e compact air-handling
unit is situated on the
door of the sheet metal
switchboard box.
Preparation for Commissioning
Inspection before First Start-Up,
General Routines and Checks
e service panels are provided with hinges and external closu-
res which serve also as handles. One of the safety closures of
each door is always equipped with a lock to prevent access by
unauthorised persons.
When performing any check, the device must always be safely
disconnected from the power supply!
Mechanical connection
Before first start-up check the following mechanical parts:
Check alignment of the air-handling unit.
Check whether all components of the air-handling unit are
installed and connected to the air distributing ducting.
Check whether all cooling and heating circuits are connec-
ted, and whether energy media are available.
Check whether all condensate drainage kits are connected.
Check all the condensate drainage siphons for correct
setting (positive/negative pressure) and whether they are filled
with water.
Check the installation of all required vibration damping ele-
ments.
Electric Wiring
Check the following items (according to the project):
Check whether all external electrical connections are made.
Check the proper wiring of all individual electrical compo-
nents of the air-handling unit.
Check whether all required external M&C components are
installed and connected.
Check whether all internal connectors are interconnected
(applies for deliveries of disassembled units).
Check the protection conductor interconnection.
Check the grounding of the unit.
Filter Inserts
Also check:
Check the filter inserts for cleanliness and intactness.
Check whether the filter inserts are inserted to the rear end
position.
Check whether the differential pressure sensors are set to
the required end pressure loss of the filter. see figure.

(EN 13053:2006 E)
G3, G4 150 Pa
M5, M6, F7 200 Pa
F8, F9 300 Pa
Water and Glycol Heaters and Direct Evaporators
Check the heat-exchanging surface fins for damage.
Check the condition of the inlet and outlet piping.
Check the connection and elements of the cooling circuit.
Check the cooling circuit piping for proper insulation.
Check the connection of the cooling circuit.
Rules for Separate Installation of M&C Elements
If the unit is delivered without the control unit, it is not equipped
with measuring and control elements.
The following rules are applied for the installation of these
elements:
If possible, install the sensors in the prepared holders.
Run the cable routes so that it will not interfere with func-
tional parts of the unit and prevent removal of the components
(filters, fans, heat-exchangers and heat recovery). e route to
the connection point or installed cable inside the unit should be
as short and straight as possible.
To run the cables through different sections of the unit's,
use the cable through with grommets.
e fans are designed as removable units and the motor
cable connection must allow the motor to be pulled out!
Secure the cable properly using the fixing points or cable
protectors and grommets to pass through the sheet metal
parts.
For running the cables in and out of the unit, use the com-
mon grommet installed on the top casing of the unit.
Use grommets of the proper diameter to run the cable
through and always run only one cable through each hole in the
grommet.
e precondition for unit operation is the installation of func-
tional antifreeze protection elements of the heat-exchangers,
plate or rotary heat exchangers, including active protection of
the unit when reaching the final pressure loss of filters
.

Commissioning – Inspection
Commissioning
e air-handling unit may be commissioned only by a properly
qualified person. Prior to first start-up of the air-handling unit, an
inspection of the wiring of all connected components of the air-
-handling unit must be performed by a qualified technician. Until
the air-handling system is adjusted, the air-handling unit can only
be put into operation when the regulating damper in the air-han-
dling unit inlet is closed. Operating the air-handling unit while the
air-handling system is misadjusted can cause motor overloading
and permanent damage. If the second stage of filtering is included
in the air-handling unit, it is advisable to run the testing operation
with the second stage filter inserts removed.
Safety Measures
It is forbidden to start the fans of the air-handling unit if the
service doors are open or removed.
e hazard of trapping by moving parts is indicated by a
label situated on the service door of the air-handling unit.
Service doors must always be closed during air-handling
unit operation.
Before starting any work on the fan block, the main switch
must always be turned off and secured to avoid accidental star-
ting of the motor during service work on the fan block.
When emptying the heat exchanger, the water temperature
must be below +60 °C.
e connecting piping of the heater must be insulated so its
surface temperature will not exceed +60 °C.
Checks during First Start-Up
During First Start-Up
Check the proper direction of the impeller rotation following
the direction of the arrow on the impeller (to carry out this
check use run-out of the switched off fan).
Check the proper direction of the rotary heat exchanger
rotor rotation following the direction of the arrow on the rotor
and free rotation without dragging.
Check the input current of connected equipment (it must
not exceed the maximum permissible value stated on the ra-
ting plate).
Check the condensate drainage for correct operation, i.e.,
the level of water in the siphon. If the water has been sucked
off, it will be necessary to increase the height of the siphon
Check the condition and position of the filters.
During the testing operation, it is necessary to check the air-
-handling unit for unusual noises and excessive vibrations. e
testing operation must last at least 30 minutes. If the unit vib-
rates too much, it is necessary to again check the fan assembly
and perform vibration intensity measuring, if necessary. If the
vibration intensity exceeds 2.8 mm/s, measured at the motor
bearing shield on the impeller side, the fan must be checked
and balanced by professional staff. During the testing opera-
tion, it is necessary to adjust (regulate) the entire air-handling
system. Before putting the air-handling unit into permanent
operation, it is recommended to replace or regenerate the filter
inserts. Aer the test operation has finished, the air-handling
unit must be inspected. Special attention must be paid to the
proper function of the condensate drainage.
Operating Checks and Service Regulations
Service Regulations
e user is responsible for the device operation. When putting the
air-handling device into permanent operation, we recommend the
supplier (installing company) in collaboration with the designer
to issue service regulations in accordance with applicable legal
regulations. We recommend including the following in these
service regulations:
Air-handling device assembly description, its intended use
and a description of its activities in all operating modes.
Description of all safety and protective elements and their
functions
Health protection principles, safety and operating rules to
be observed when operating the air-handling equipment.
Requirements for operating staff qualifications and training,
a nomenclature list of personnel authorized to operate the air-
-handling device.
Detailed emergency and accident instructions to be follo-
wed by the operating staff
Operating particularities during different climatic conditions
(e.g. summer or winter operation).
Obrázek 20

Regular Inspections
Inspection, checking and maintenance schedule, including a
list of checking steps, and their recording
Records of operating staff training, operation, inspections
and cleaning of the rotary heat exchanger (subject to guarantee
validity).
Unit Operation Screening Checks
e operating staff's checking activities must be focused on
the following:
e air-handling unit operation and functioning, leak ti-
ghtness of connections, inspection doors and service panels,
temperature of energy media and transported air.
e condition and operation of systems associated with the
air-handling unit, whose proper functioning is needed for proper
operation of the air-handling unit as well as for operation of the
entire air-handling system. ese are:
Wiring
M & C system
Water heater (VO) system – circuit, pump operation
and water filters (also in SUMX)
Cooling system
Sanitary installation - condensate drainage
Regular Inspections
e user will determine the intervals for regular inspections of the
air-handling unit according to the operating conditions, however,
at least once every three months. Within the framework of the
inspection, check the following:
Overall Check
Cleaning of all parts of the air-handling unit:
Min. 1x per year or more frequently, if needed (recommen-
ded cleaning solution – 10 parts of a dish washing cleaner or
similar agent, 45 parts of Isopropanol, 45 parts of water – pH
5–9, do not use cleaners containing active chlorine).
Max. 50°C when a steam cleaning equipment is used.
When a high-pressure cleaning equipment is used, there is a
risk of paint damage, especially in the elbows.
To remove heavy dirt and clean the corners, use so
brushes to avoid damage to the metal or painted surface.
Using wire, hard plastic (rice) brushes of other abrasive agents
is prohibited.
First test clean a small area of the surface and then carry it
out on evenly on the whole surface to prevent possible differen-
ces in colour
Check the functionality of the condensate drainage
No traces of stagnant water must be found inside the unit.
Pour 1 litre of water
into the tray. is water
must be safely drained
through the drainage
from the tray.
Fan Inspection
Check the fan ope-
ration (strange noises
and excessive vibrations
of the unit) and, if needed, balance the fan, refer to the section
Unit First Start Inspection.
Check the impeller for cleanliness.
Check the impeller for integrity and free rotation.
Check the assembly screw connections for tightening.
Check the silent blocks for condition (damage).
Inspection of Dampers
Check the dampers for cleanliness.
Check the damper flaps for free rotation.
Check the damper flaps for full closing.
Filter Inspection and Replacement
Check the filters for condition and fouling (if fouled or da-
maged, the filter inserts must be replaced).
e used filter inserts must be disposed of in an ecological
way.
When replacing filter in-
serts, always check the
condition of the sealing;
if damaged, replace the
sealing with a new one.
When checking or repla-
cing the filters, observe
the following steps:
When replacing the fil-
ter inserts, pull out them
from the guiding bars
towards the service side
of the unit. Check the sealing in the grooves. Insert the new filter
insert in the same way into the groove under the sealing until it
is seats on the end stop. When inserting a bag filter, be careful
not to catch the bags and damage or tear them. It is advisable to
perform regular inspections of the frame filters, especially if high
air humidity is present or if it fluctuates through the day.
Checking the Exchangers (Heaters, Coolers)
Clean the dirty heat exchanging surfaces of the heat-ex-
changers using a vacuum cleaner or hot-water cleaniner.
It is important to check the air-venting of the exchangers.
Permanently check the functionality of the condensate drai-
ning system (coolers).
Important:
Be very careful when cleaning the exchanger's fins to avoid
mechanical damage to the fins and injury caused by the sharp
edges of the fins. If taking the exchanger out of operation
during the winter season, the water must be completely
drained from the exchanger, and possible water residuals
must be removed, e.g. by blowing out the exchanger with
pressurised air; or the exchanger must be filled with a safe
antifreeze solution of water and glycol. Water residuals can
freeze in the exchanger and damage the copper pipes.
Steam Generator Check
All prescribed checks are included in the Installation Instructions
attached tothesteam generator. Pleasefollowthese instructions,
especially the following:
Figure 22
Obrázek 21

CAKE Air-handling units
15
Regular Inspections
During the first several hours of operation: Check the water
conductivity (min. 5 refills per water exchange cycle, sparking
and max. current checking), check the cylinders for condition
(water leakage) and operation and check the tightening of
electrical connections.
Each 3 months of operation: Check the steam generator
operation (number of water fillings per cycle) and the condition
of the cylinders (water leakage, condition of electrodes and
inner casing of the cylinder).
Each year or aer 2500 operating hours: Replace the
boiling cylinders, check the condition and shape of hoses, check
the sealing of the distributing tubes inside the chamber and
check the tightening of electrical connections.
Warning:
Electrical equipment! e steam generator cylinder can be
hot. In case of water leakage, the hazard of burning and/or
electric shock exists! e intervals of inspections and service
life of parts can vary depending on the water quality and
operating conditions.
Rotary Heat Exchanger Inspection
Rotary heat exchanger condition inspections must be performed
regularly; checking the rotor for cleanliness is the most important
part of these inspections. e user will determine the intervals
for regular inspections according to the operating conditions,
however, at least once every 3 months. At the same time, the
user must perform the following checks:
Check the rotor for free rotation
Check the rotor for cleanliness.
Check the condition and tightness of the brushes and free
rotation of the rotor.
Check the rotor condition and tension of the driving belt.
Check fouling of filters; inlet and outlet.
Important:
If fouled or damaged, the filters must be replaced with new
ones immediately. If any fouling of the rotor is found, the user
must ensure its expert cleaning. e rotary heat exchanger
rotor can be cleaned by pressurized air, steam or pressurized
water. Failure to perform maintenance can result in perma-
nent damage to the rotary heat exchanger rotor and very
expensive repairs. If the proper procedure of cleaning is not
observed, there is a high risk of serious damage to the rotary
heat exchanger rotor!
Check of Cooling and Heating Circuit Liquids
Recommended water quality used in heat exchangers working
with low-pressure heating water or cooled water:
Use good quality water – e.g. drinking water without salt
and calcium compounds – to prolong service life and increase
efficiency of the heat exchanger.
Once a year, check the limit values included in the table below
to prevent damage to the hydraulic system and its components.
If needed, add water soening agents.
Note: ese water quality limit values are only intended for
information purposes and cannot be used for the equipment's
