The unit can be used in rooms normal according to IEC 60364-5-51, resp. ČSN 332000-5-51 ed. 3, ČSN 332000-1 ed.2. The ambient tempera-
ture must be between -20 and +40 °C.
The unit can transport air without solid, fibrous, sticky, aggressive chemical and explosive additives. The maximum permissible supply air tem-
perature must not exceed +40 °C. The maximum humidity of the air flowing through the unit is 17 g / kg s.v. (84 % r.h. at 25 °C).
If, due to the immediate climatic conditions, the humidity of the outdoor intake air reaches 100 % r.h. (wet steam), it is at the operator‘s discretion
whether to keep the unit running with the risk of temporary separation of moisture on the internal parts of the unit (eg filters, flaps,…). This humidity
cannot be the subject of a complaint.
CAUTION!
For units with a direct evaporator (marked DX and DXr in the unit code), the design air flow through the unit must be observed
when operating the direct evaporator/condenser. It is acceptable to reduce the flow in cooling and heating mode by a maximum
of 20 % of the design air flow. For proper operation of the direct evaporator, it is necessary to observe the necessary heat or cold
consumption from the heat exchange surface of the evaporator/condenser. If the design amount of energy is not consumed, the
condensing unit / heat pump may report a fault in the pressure protections (LP, HP) of the cooling circuit and the condensing unit
/ heat pump may cycle in ON/OFF mode.
!
CAUTION!
Units with direct evaporator (marked DX and DXr in the unit code) must be equipped with a mixing flap (marked MX in the unit
code), which ensures, if necessary, min. condenser/evaporator inlet temperature of +10 °C.
!
CAUTION!
The unit shall not be transported above
persons!
!
CAUTION!
The holes in the frame and legs are not intended
for the unit hinging.

without the transport pallet it is necessary to support the unit on the underside over the entire surface to prevent damage and to pay attention
to the condensate outlet opening on the underside of the unit. During lifting by a crane, it is necessary to pass the ropes through the transport
pallet or under the unit to prevent their slipping. THE UNIT CAN BE HANDLED ONLY BY SUPPORTING OR TYING UNDER THE UNIT FLOOR -
THE UNIT CANNOT BE LIFTED BY THE CEILING OF THE UNIT OR OTHER PARTS (SUCH AS PNEUMATIC FLANGES, EXCHANGER OUTLETS
ETC.) Ensure proper balancing of the transported unit. The ropes above the unit must be stretched to prevent damage. Outdoor versions of the
units are equipped with transport profiles for securely threading the tie-downs under the bottom of the unit.
The units must be stored in dry and dust-free areas where the ambient temperature does not fall below + 5 °C. The unit must be protected
during storage against mechanical damage, dirt and corrosion caused by permanent condensation of water vapour on the surface of the unit.
During storage, it is necessary to protect the units against snow, rain and other weather conditions (store in a covered warehouse).
When accepting the unit, it is necessary to check whether the product was delivered in the agreed design and extent, whether it was not
damaged during transport, whether there is no condensed water under the plastic wrap (if there is moisture under the packaging, unpack the
unit and dry in a covered dry place) . In case of damage during transport, the transferee must record the extent of damage in the Delivery Note,
obtain and send photo documentation to ELEKTRODESIGN ventilátory, s.r.o. Failure to comply with this procedure exposes the transferee to the
risk of rejection of the complaint by ELEKTRODESIGN ventilátory, s.r.o.
4. TRANSPORT, STORAGE, ACCEPTANCE

5. INSTALLATION
The unit can only be installed by a professional installation company authorized in accordance with the Trade Licensing Act.
5.1 PLACE OF INSTALLATION
The unit can only be installed in accordance with the „Environmental Protocol“, in which the characteristics of all devices that can be placed in
this space are clearly defined, and it is not possible to place devices that would affect these conditions in any way. The unit has a limited load
capacity and is certainly not intended for storing and depositing any materials, especially objects of considerable weight. This could deform the
housing of the unit or severely damage it. These damages are not covered by the warranty. After connecting the unit to the HVAC piping, it is
necessary to check the insulation of the HVAC piping in parts with a risk of condensation. Condensate formed in the air duct can, in unfavourab-
le conditions, spill into the interior of the unit, where it is not separated and may flow out of the unit. The result of this process can be damage to
adjacent building structures.

5.2.3 CONNECTION OF ELECTRIC HEATER (MARKED „DI“ IN UNIT CODE)
The unit equipped with an electric DI heater is connected to the relevant control system and further to the electrical network. The general safety
regulations for the assembly and installation of electrical equipment apply to this equipment. On the front of the unit there is a cover with a release
button for the non-automatic thermal fuse. The non-automatic thermal fuse reacts in the event of overheating of the heater‘s heating block (tem-
perature above + 120°C). The electric heater is also equipped with an operating thermostat with automatic reset (set temperature is + 60 °C, when
it is exceeded, the operating thermostat opens and switches off the heater, after cooling below +60°C the heater automatically switches on again).
Table of minimum air flows through the electric heater of DUOVENT®COMPACT RV TOP unita:
CAUTION!
It is forbidden to remove, bypass or disconnect safety
devices, safety functions and protective devices! Any
intervention in the internal connection of the heater is
forbidden!
!CAUTION!
before service works!
• The unit must be disconnected from the power
supply
• The fan impellers shall not rotate
• Electric heater bars must be cooled to min. 30 °C

The release button is accessible by removing the front cover (loosen 2x M6 screws) on the outer casing of the unit.
If the electric heater emergency thermostat of the unit trips again, it is necessary to immediately look for the cause of the fault. Repeated manual
reset of the heater overheating error by a button on the heater is inadmissible and is not a solution to the fault. The reason for this type of failure
may be insufficient air flow through the electric heater of the unit, which will cause the heating rods to overheat and the intervention of the emer-
gency thermostat. The solution is to increase the air flow to the required minimum level according to the following table.
During maintenance, it is necessary to check the tightening of the terminals, clean the space of the heater terminal block from dust and dirt,
monitor whether some components show signs of excessive warming, water leakage, mechanical or other damage. Increased attention must
be paid to safety circuits, especially the thermal protection of the heater, including the correct response of the control system or power supply
switchboard. Faults found must be rectified immediately. These inspections are carried out at least once a year (or more often according to local
conditions) by an authorized professional service company.

5.2.4. CONNECTION OF WATER HEATER
The unit fitted with the water heater (unit code DCA or DCB) is connected to the heating media by means of three-way mixing unit (see „Types of
ESU control units“). The water heater outlets are located on the front of the unit and are threaded. The exchanger must be connected in counter-
-current to the flow of air passing through (in concurrent connection, the exchanger loses approx. 25 % of its output). When tightening the heat
exchanger connections, it is necessary, for example, to hold the heat exchanger neck with a second wrench so that the tightening torque is not
transmitted to the heat exchanger body.

For the water heater to function properly, it is necessary to bleed the heater after connecting and filling the system with heating water. The vent
screws are located directly at the heat exchanger connection necks. The vent screws are accessible from the outside of the service side.
Before starting service work on the heat exchanger (when replacing it), it is necessary to drain the heating water distribution system connected
to the heat exchanger and drain the heat exchanger itself using the drain screws on the heat exchanger collectors. The heat exchanger can then
be disconnected from the heating water distribution system and removed from the unit.
Max. operating water temperature of water heaters: +110 °C
Max. operating water pressure of water heaters: 1,6 MPa
Hydrogen exponent of heating water: pH 7-9
Heating water hardness: 1,0 mval / l
If necessary, water heaters can be operated with a heating medium based on a solution of water and ethylene glycol or propylene glycol - antif-
reeze mixture.
For water heaters, it is necessary to pay attention to the correct installation and function of the frost protection. The frost protection sensor is
located on the heating water return, or a capillary frost protection thermostat is used (depending on the unit).
All pipes must be connected independently of the heat exchangers - the heating water pipes must not act on the necks of the heat exchangers
due to their weight and expansion. We recommend the antifreeze mixture as a heat transfer medium for all outdoor units.
Units taken out of service must be protected against freezing by draining water from all parts of the unit. Residual water from the exchanger can
be expelled with compressed air.
When starting the unit at an outdoor air temperature below +5 °C, the active fluid supply to the heater must be opened before starting the fan,
which must have the projected temperature at the heating water supply to the heater. I.e. the boiler circuit must be in operation, the boiler must
heat and provide the warm water to the system.
For outdoor units, we recommend filling the water heater heating system with antifreeze mixture.
CAUTION!
For unit variants with water bivalence and heat pump (marked DXr DCA or DXr DCB in the unit code), it is recommended to use an
antifreeze mixture of water and ethylene glycol (eg. FRITERM E Stabil) in min. concentration 1: 2 (i.e. 1 part of FRITERM E Stabil: 2
pats of water). If the antifreeze mixture cannot be used, a year-round supply of heating water must be provided in front of the water
heater control valve so that all frost protection functions are active. For units that are not equipped with a Digireg control system, it
is recommended to install a capillary antifreeze thermostat behind the water heater in the direction of air flow, which activates the
antifreeze protection functions of the water heater in the customer control system of the unit.

For the water cooler to function properly, the cooler must be vented after connecting and filling the system with cooling water. The vent screws
are located directly at the heat exchanger connection necks. The vent screws are accessible from the outside of the service side.
Before starting service work on the heat exchanger (when replacing it), it is necessary to drain the heating water distribution system connected
to the heat exchanger and drain the heat exchanger itself using the drain screws on the heat exchanger collectors. The heat exchanger can then
be disconnected from the cooling water distribution system and removed from the unit.
Max. operating water pressure of water coolers: 1,6 MPa
Hydrogen exponent of heating water: pH 7-9
Heating water hardness: 1,0 mval / l
The water cooler section is equipped with a drip eliminator, which must always be installed in the unit during cooler operation.
All piping must be installed independently of the heat exchangers - the cooling water piping must not act on the necks of the heat exchangers
due to its weight and expansion. We recommend the antifreeze mixture as a heat transfer medium for all outdoor units.
Units taken out of service must be protected against freezing by draining water from all parts of the unit. Residual water from the exchanger can
be expelled with compressed air.
DCA/DCB/DCC water exchanger can be used also for water with antifreeze mixture (based on propylene-glycol, ethylene-glycol
etc.). We recommend e.g. concentrated antifreeze liquid FRITERM E STABIL or FRITERM P PLUS (recommended dilution for
temperature resistance to -18°C 1 : 2 = 1 part FRITERM E STABIL: 2 pats of water). The recommended dilution for each type of
coolant and the required frost resistance is included in the packaging of these antifreeze concentrates. For DCA / DCB / DCC
water exchangers, we always recommend filling with antifreeze mixture with min. concentration of 20:80 because the liquids con-
tain, among other things, inhibitors of corrosion. At least a minimum freezing resistance of the mixture (about -5 °C) is ensured.

5.2.6 CONNECTION OF DIRECT EVAPORATOR
The unit equipped with a direct evaporator (DX, DXr) is connected via a Cu pipe to the appropriate condensing unit or heat pump (the method
and design of the connection is not the subject of these installation instructions). The direct cooler outlets are located inside or outside the unit
(depending on the required design). The evaporator is filled with dry air or nitrogen from the factory. After removing the valves on the evapora-
tor necks, work on the refrigerant circuit assembly must begin immediately. The connection of the refrigerant circuit for direct cooling must be
carried out by a specialist company. It is mandatory to perform a „Refrigerant leak test“ on the refrigerant circuit. This test is performed only by a
technician with the appropriate authorization (according to the law).
5.2.7 CONNECTION OF CONDENSATE DRAIN
To ensure the drainage of condensate, the outlet must be connected to the sewer system via a siphon with an odour stopper. The condensate
drain neck is usually located below the rotary regeneration heat exchanger and water cooler or direct evaporator. In the case of a unit configura-
tion without water cooler or direct evaporator, the condensate drain is blinded.

Δp … absolute value of vacuum or overpressure at a given location of the unit
On DUOVENT®COMPACT RV TOP units, the condensate drain is located under the rotary heat exchanger and under the condenser / direct eva-
porator in the vacuum section of the unit! This means that the absolute pressure in this condensate drain is lower than the barometric pressure
outside the unit! If no siphon is connected, air is drawn in from around the unit at a very high velocity through the condensate drainage neck
(opening Ø 16 mm) and the air drawn into the unit makes it impossible for the condensate to drain out of the unit!!!

Scheme of overpressure siphon (type SF-P 400 PR):
Under the air cooler (unit code DX, DXr or DCC) the siphon is located in the unit overpressure part!
Vacuum siphon (SF-P 300) - contains a ball that serves as a non-return valve for the correct function of the siphon not flooded with water and
prevents the penetration of odours into the unit. The siphon must be fitted to the unit gas-tightly via the enclosed rubber sleeve. Max. usable
vacuum 1100 Pa.
Overpressure siphon (SF-P 400 PR) - the siphon must be completely filled with water to prevent the penetration of odours from the sewer into
the interior of the unit when it is shut down. Suitability of the overpressure siphon can be found by visual inspection. When the device is running
and started, the water must not be forced into the drain pipe after the siphon has been filled. Max. usable overpressure 1100 Pa.
Siphons are used individually for each condensate drain on the unit. The condensate drain behind the individual siphons of one unit assembly
can be connected to one pipe. Never connect the unit outlet necks by piping and then to single siphon. In winter, the outdoor units must be tem-
pered by a condensate route, including anti-freeze siphons, e.g. with electric heating cables. After mounting, fix the siphon so that it does not
disengage spontaneously due to the weight of the water inside.

5.2.8 CIRCULATION (MIXING) FLAP
The unit of MX variant features integrated mixing flap located in front of the rotating exchanger in direction of the exhaust air (ETA). This flap
allows you to efficiently mix part of the exhaust air with fresh air or allows the circulation mode of the unit. In this mode only inlet fan is in
operation. The circulation is mainly used for preheating or pre-cooling to the desired temperature. Circulation mode requires fitting the unit with
additional inlet flaps (KL must be specified in the unit code).
The circulation servo (of mixing damper) is accessible by opening the unit door (ETA air side door).
Types of actuators for the circulation or mixing flaps:
5.2.9 SUPPLY AND EXHAUST FLAPS (ODA-OUTDOOR AIR, ETA-EXTRACT AIR)
The basic version of the unit is equipped with a outdoor air and exhaust air flaps (ODA and ETA). The arrangement of the flaps in the unit is
shown on the picture in chapter 5.2.2. When using a variant of the unit with a water heater DCA or DCB, it is recommended to mount an actua-
tor with an emergency function on the fresh air inlet flap.
