If the AHU will have lights fitted on site make sure that sections with condensate (cooling sections),
humidifier sections and wet sections are equipped with lights with appropriate protection of at least
IP55. Switches or junction boxes mounted on the outside of rooftop AHUs must also have at least
protection class IP55.
For AHUs with integrated control and lighting, an additional power supply for the lighting must be
provided and separated from the power supply for the control cabinet. This ensures that the light
also can be switched on during repair work, despite the main switch being switched off (prerequisite
for access to the AHU).
7.10 UV section
This section contains UV-C-lamps to destroy germs on surfaces as well as in the air in the direct
radiation area. If nothing else is agreed, these lamps should be mounted as evenly as possible and
distributed on the ceiling, the rear sidewall and on the bottom. The number of lamps to be installed
will be determined in consultation with your EUROCLIMA office.
EUROCLIMA is not able to determine, the amount of germs killed through the use of UV-C-
lamps.
The lamps will be mounted, cabled and led to the junction box (inclusive switch) outside of the AHU
by EUROCLIMA.

The safety instructions in
chapter 2.2 ( Indications for minimizing specific
hazards
)
and the user manual of the lamp manufacturer (delivered with the
present instruction manual) have to be considered.
-
Due to the high voltage of the lamp, maintain it safely and do not work with it
whilst it is on. Danger of life due to electrical shock!
-
DANGER:
UV-risk class 3. These lamps emit strong UV radiation, which could
lead to serious injuries of skin and eyes. Avoid eye and skin contact with un-
screened products. Use them just in a closed environment, which protects the
user against radiation.
-
It is highly unlikely that a lamp break has impacts on your health. If a lamp
breaks, air the room for 30 minutes and remove the broken pieces, preferable
with cut resistant gloves. Put them into a sealed plastic bag and take them to
the local recycling station. Don not use a vacuum cleaner.
8 Commissioning
8.1 Preliminary steps
-
Clean thoroughly the AHU and all components of dust, swarf and other debris.
-
Remove all loose parts like tools, etc. and any documentation 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
-
Ensure that the duct pressure corresponds to the pressure for the nominal air flow and the
pressure specified in the technical data sheet.
-
Ensure that all planned filters are mounted. Not mounted filters can overload the fan motor.
-
All cables must be checked for damage to the insulation and replaced if necessary.
