Units extract air condensate tray are with self controlled heating cable. Heating cable are activated
in heating mode only. The water trap must be installed D = 28mm.
Ductwork
The air flows in/out air handling unit through ductwork. We recommend using galvanized steel (Zn
275 gr/m
2
) ductwork, to ensure easy cleaning and durability. It is necessary to use the ductwork system
with low air flow rate and small pressure drop to have necessary air volume and low sound level and save
the energy. The appropriate sound attenuators will reduce the noise level of the fans in the premises.
All ductwork should be insulated with 50–100 mm thickness insulation to avoid the condensation.
Note:
temperature sensor B1 has to be mounted in the supply air duct under electric heater (see the functional diagram in Control
System Electrical Installation and Operation Manual). It is necessary to leave space in straight air duct for sensor mounting and
guarantee the space for maintenance and service work. Minimal space between the unit and B1 sensor is the space of double air
duct diameter.
Ductwork, steelwork and any other services should not be supported off the unit.
It is recommended to install air dampers in the inlet and outlet ducts. For ventilation
units with water air heater, it is mandatory to use inlet air closing damper with spring
return mechanism.
In the air intake duct, before the AHU

it is recommended to install additional air filter
(for example G4 class), to protect heat-pump components from dust.

Final Inspection
After installation of the unit, a thorough inspection should be carried out. This should include in-
specting the inside of the unit and removing debris and tools, which may have been left behind by on
site contractors. Replace any panels, which may have been removed and close all access doors, ensuring
that the door sealing gaskets have not been damaged.
