3 Reception control / transportation / unloading / storage
3.1 Reception control
-When the AHUs arrive, please check the scope of delivery for completeness and damage im-
mediately. Scope of delivery:
oEUROCLIMA air purifier
oInstruction manual (loose in transport bag on the outside of the AHU)
oTool wrench (hexagon socket / Allen bit 5 mm) (loose in the transport bag on the out-
side of the AHU)
oMounting bracket (loose in the transport bag on the outside of the AHU)
o2 fixing screws for mounting brackets (loose in transport bag on the outside of the AHU)
oPre-filter and HEPA filter (inserted in the AHU)
-If damages are found, complete immediately a damage report. Only then the transport com-
pany can make the claim with the insurer (Note damage on the shipping documents with date
and signature in the presence of the carrier). Complaints about apparent damaged or missing
parts of the delivery cannot be subsequently recognized, if procedures are not followed. In
case of complaints please inform immediately your contract partner.
-Depending on the environmental conditions, a superficial corrosion may occur on components
like e.g. motor shafts, fan shafts, clamping bushes, sheet cutting edges. The resulting corrosion
layer protects the underlying material from further corroding and does not represent a defect of
the component or the device (see also chapter 7 (Maintenance)).
WARNING!
Danger due to tipping over
Beware of the risk of the AHU or narrow parts tipping over when removing the
safety straps. Secure the AHU against tipping.
WARNING!
Danger due to thin or sharp sheet metal edges
Thin or sharp sheet metal edges such as roof plates or corners of frames on the
parts of the AHU represent a source of injury. This must be considered when han-
dling the AHU. Gloves, safety shoes and long work clothing must be used.
3.2 Transporting AHU‘s
3.2.1 Necessary general measures
WARNING!
-The technical data (dimensions, weight, etc.) in chapter 1.5.2 (Technical
data) must be observed.
-Make sure that nobody is under the raised load.
-Before lifting, check that there are no objects on the load.
-Riding and climbing on the load are prohibited!
-Transport the AHU very slowly and completely horizontally. When transport-
ing, a maximum lifting speed of 10 m/min is permissible.
-After the section is lifted slowly from the floor for a few centimeters, stop the
operation. Now check the correct course of the load carrying equipment and
that the lifting and fastening elements are all secure and safe.

Instruction Manual
AirSanitizer
V12-20.0 11/28
-Before further lifting, check by visual inspection that no conspicuous defor-
mations can be detected on the suspension means.
-Avoid jerky lifting.
-Loads must be picked up and set down in such a way that unintentional over-
turning, falling apart, sliding or rolling of the load is avoided.
-Due to the dimensions and weight of the AHU (see chapter 1.5.2 (Technical
data), the transport and unloading of the AHU must be carried out jointly by at
least 2 qualified persons.
-Personal protective equipment: safety shoes must be worn during transport
and unloading.
3.2.2 Transportation by forklift / lift truck
WARNING!
Danger due to loss of stability of the AHU
During transport and unloading, there is an increased risk of the AHU tipping over
due to its high center of gravity. Therefore, if possible, transport the AHU lying on
the pallet, see Figure 2. If this is not possible, the AHU must be secured against
tipping with additional measures provided by the customer. When unloading and
setting up, secure against slipping and tipping over until the AHU is fully assem-
bled.
Each AHU is delivered on its own pallet and can be unloaded using a forklift and transported using
a forklift or pallet truck. In principle, force may only be applied through the pallet, see Figure 2.
Figure 2: Correct transport
Figure 3: Incorrect transport
The center of gravity must be centrally located between the forks (see Figure 4).

Instruction Manual
AirSanitizer
12/28 V12-20.0
Figure 4: Center of gravity centrally between the forks
3.3 Storage
The AHU is generally packed in nylon. This package is suitable to protect the AHU during loading
and unloading from bad weather, but not for outdoor storage. The insertion into a dry area after un-
loading is therefore essential for the preservation of the AHU.
NOTICE!
Removal of nylon packaging
Remove the nylon packaging after delivery and place the AHU in a dry, weather
protected area: the risk of corrosion due to the lack of ventilation in combination
with a higher humidity under the nylon packaging is possible. For example, white
rust may be formed within a short time on galvanized surfaces. It can further arise
that an excessively high temperature is created under the packaging, which can
also cause damages to the components.
4 Assembly / Erection
4.1 Space requirements
The AHU must be positioned in the room so that it has good access to the room air. Therefore, the
AHU must not be covered or placed behind or in a cupboard, e.g.
At the location of installation, it should be spatially possible to carry out proper maintenance and, if
necessary, to remove components. For this purpose, a free working space from the AHU width +
300 mm must be available on each side. For the space requirement, it must also be considered
that the ON / OFF switch (operating lamp) on the rear of the AHU remains accessible and that the
door can be opened far enough to allow changing the filters.
4.2 Anti-tilt protection / assembly mounting bracket
WARNING!
Danger due to AHU tipping over
Due to the high center of gravity of the AHU and / or accidental bumping against
the AHU, there is an increased risk of the AHU tipping over. Serious or life-threat-
ening injuries may result. Therefore, the AHU must be firmly anchored to a wall im-
mediately after installation using the supplied mounting bracket.
To secure the AHU against tipping over / falling, it must be mounted in the room as follows:

Instruction Manual
AirSanitizer
V12-20.0 13/28
1. The mounting bracket supplied loose (see Figure 5) is to be fixed to the rivet nuts at the
rear of the AHUs blow out hood in exact alignment using the enclosed fixing screws (see
Figure 6), see Figure 7.
2. Move the rear of the AHU to the wall and align it horizontally.
3. The mounting bracket must be fixed firmly to the wall with suitable fixing material (screws
and dowels), see Figure 8 and Figure 9. Fixing material is not included in the scope of
supply. The fixing material must be suitable for the wall conditions; consult your local spe-
cialist retailer.
4. The mounting bracket leaves a small distance to the wall so that the ON / OFF switch at the
rear of the AHU is accessible.
5. Check that the fixing material is firmly fixed.
6. Check the stability of the AHU.

4.4 Erection
4.4.1 Potential risks that may arise at the erection site
-Cleaning work - including wet cleaning - can be carried out on the inside and outside of the
AHU. During this work, leakage / dripping of cleaning fluid is possible.
4.4.2 Actions to prevent potential risks
These risks can be prevented by following actions:
-The AHU must be set up in such a way that it is easy to assemble and maintain.
-Appropriate safety precautions must be taken in accordance with the installation so that per-
sons, buildings, and equipment are not endangered by falling parts (e.g. tools, screws, etc.).
The decision on suitable measures must be made by the customer in knowledge of the situation at
the location. The installer or the operator of the AHU must provide preventive protection in accord-
ance with the instructions given. In this context, it is advisable to take out insurance against dam-
age.
4.5 Door
The accessibility to the inside of the AHU is provided by a hinged door with a butterfly lock. To
open (see Figure 10) and close (see Figure 11) the AHU, a tool wrench (hexagon socket / Allen
bit 5 mm) is always required (see Figure 12).
Figure 10:Service door / lock open
Figure 11:Service door / lock closed
Figure 12:Tool wrench (hexagon
socket / Allen bit 5 mm)
DANGER!
Danger due to rotating parts
Rotating parts can cause extremely serious injuries. Therefore, the service door
must be locked tightly with the tool wrench before switching on and during opera-
tion. The tool wrench must be kept out of reach of unauthorized persons. Before
opening the AHU, disconnect the AHU from the power supply by using the power
plug and the overrun time of the fan must be observed.

5 Commissioning
5.1 Preliminary steps
-Clean thoroughly the AHU and all components of dust, swarf, and other debris.
-Remove all loose parts like tools, documentation, etc. from the AHU. Such parts can be sucked
in by the fan and lead to its destruction.
-Check all bolt connections and electrical connections and retighten if necessary.
-All cables must be checked for damage on the insulation and replaced if necessary.
-Insert the power plug into a properly fused power socket.
-Lay the power cable in such a way that no one can step on it and that there are no tripping haz-
ards.
-The power connection must comply with the specifications in chapter 1.5.2 (Technical data).
Here are some important points to consider, which could cause problems after transport or inap-
propriate AHU handling:
-Rotate the impeller of the fan by hand, to check whether it rotates freely.
-Check the motor connection and the matching of the supply voltage at the rated voltage - a
fluctuation of supply voltage between +/- 5 % is permitted.
5.2 EC motors
EC motors are variable through an integrated frequency converter.
5.3 Air filters
NOTICE!
Check air filter for tight fit
Before commissioning the AHU, all filters should be checked for tightness, as
otherwise they could be sucked in and could lead to damage.
5.4 Potentiometer
The volume flow (air exchange rate) is factory pre-set by using a potentiometer. If it is necessary to
adjust the volume flow, it can be set by using this potentiometer. The potentiometer is located in-
side the AHU (see Figure 13) and is accessible after opening the service door.

A timer switch installed on site can be used for a temporal control of the AHU (ATTENTION: Note
the switching capacity!).
7 Maintenance
EUROCLIMA AHUs are built mostly maintenance free and easy to maintain when required. The
maintenance intervals (see Table 6) are indicative for normal operating conditions. Widely differing
applications may require different intervals, what must be checked in the individual case. The exe-
cution of the described checks and maintenance needs, see chapter 7.5 (Maintenance plan), are
necessary to ensure a permanent safety operation and functionality of the AHU.
The entire AHU and all components must be checked regularly for pollution, corrosion, damage
and fixing and, if necessary, they must be cleaned or repaired.
Depending on the environmental conditions, it can lead to a superficial corrosion on components,
for example: motor, fan shafts, sheet metal cutting edges, etc. The resulting corrosion layer pro-
tects the underlying material from further corroding and does not represent a deficiency of the com-
ponent or the device. The removal of surface corrosion and treatment of the corresponding sites
are generally not required.
DANGER!
Danger due to electric shock
Before maintenance work, the AHU must be disconnected from the power by us-
ing the power plug. Indications of chapter 2 (Safety instructions) have to be ob-
served!
To order spare parts please contact your service partner.
EUROCLIMA recommends performing checks, maintenance, and repair work in compliance to the
specifications according to VDI 6022 sheet 1 and VDMA 24186 part 1.
Please note that EUROCLIMA is not responsible for damage caused by improper handling of sol-
vents and cleaning agents, and not liable for mechanical damage. Solvents and cleaning agents
may not contain alcohol for use on coated surfaces. EUROCLIMA recommends Allrain or Multirain
as cleaning agents and Sanosil or Sanirain from Hygan as disinfectants.

7.1 Electrical connection
All electrical connections must be inspected annually and deficiencies (e.g. loose cable strands,
loose screw, clamp connection, etc.) must be identified and eliminated immediately. Any dust de-
posits must be removed regularly.
The AHU is secured with a micro fuse F1 3.15 A (see Figure 1, in chapter 1.5.1 (Overview / con-
struction of the AHU)). This may have to be changed if necessary. The following steps must be
followed:
1. Pull the fuse holder out of the AHU.
2. Remove the defective micro fuse.
3. Insert a new micro fuse F1 3.15 A into the fuse holder.
4. Reinsert the fuse holder with the new micro fuse into the power supply.
7.2 Fan / motor group
7.2.1 Vibrations
WARNING!
Danger due to high vibrations / resonance frequency
Permanent operation of the fan-motor-unit at inadmissible high vibrations or at
resonant frequency (and multiples of it) can lead to severe damage of the AHU
and subsequently to damages to property or personnel.
During operation of the AHU, an excessive vibration level can occur due an unfavorable air flow,
accumulation of dirt and dust, missing and / or incorrect cleaning and maintenance
7.2.2 Fan
-Check for dirt, debris, damage, and corrosion, clean if necessary.
-Coat surface damage of the housing and impeller with zinc dust paint.
-Check the protection grid for correct installation / damaged (visual inspection).
-Test the wheel by rotating it by hand for abnormal noises.
-In case of irregular or unusual sounds, your service partner must be contacted.
-The theoretical lifetime, depending on the operating conditions, is at least 20,000 hours.
-The fan bearings are lubricated for life.
-Visual inspection: Check the wheel for any weld cracking.
DANGER!
Danger due to lack of or incorrect maintenance of the fan wheel
Deposits on the fan wheel can lead to damage (danger of fatigue fracture).
7.2.3 Motor
-Check the motor for cleanliness and clean if necessary.
-In case of irregular or unusual sounds, your service partner must be contacted.

7.3 Air filters
EUROCLIMA recommends changing the filter outside the period of use to reduce the risk of infec-
tion for other persons. When checking and changing the filters, disposable gloves and FFP3 respir-
atory protection must be used. The soiled filters must be disposed of in closed waste bags and in
accordance with local regulations.
NOTICE!
Use intended filter types / sizes
To ensure the performance and the energy-efficient operation of the AHU, the air
filters must be replaced regularly. Use only filter types and filter sizes, which are
suitable and intended for assembly (see Figure 15). For further information please
contact your service partner.
NOTICE!
Check air filter for tight fit
All filters must be checked for tight fit, otherwise they may be sucked in and
cause damage.

7.3.1 Pre-filter ePM185% (ISO 16890)
The pre-filter must be checked regularly (according to maintenance plan Table 6) for degree of
contamination, damage, odor, and moisture penetration. For inspection, cleaning and mainte-
nance, the pre-filter must be pulled out (lower filter, see Figure 15).
Check the filter chamber for dirt and clean it with a damp cloth if necessary.
The pre-filter must be changed if necessary, but at least once a year. To change the filter, pull out
the dirty filter and dispose it properly. When inserting the new filter, do not damage or touch them.
Touch the filter only by the frame to avoid damage.
