UNIT MOUNTING
To attain the best performance of the unit and to minimise turbulence-induced air pressure losses while mounting connect a straight
air duct section on both sides of the unit.
Minimum straight air duct length:
•
equal to 1 air duct diameter on intake side.
•
equal to 3 air duct diameters on outlet side.
If the air ducts are not connected or the connected air ducts are too short, protect the unit parts from ingress of foreign objects by
covering the spigots with a protecting grille or other protecting device with mesh width not more than 12.5 mm to prevent uncontrollable
access to the fans.
While installing the unit ensure convenient access for subsequent maintenance and repair. The unit must be mounted on an even
wall. Mounting the unit to an uneven surface can lead to the unit casing distortion and operation disturbance.
Unit wall mounting
Fasteners for wall-mounting are not included into delivery set
and need to be ordered separately. While selecting appropriate
fasteners consider the material of the mounting surface as well
as the weigh of the unit, refer technical data. For selection of the
fasteners for unit mounting please refer to service technicians.
Fix the wall mounting bracket at a required height and fix the unit
on the hook.
Unit floor mounting
Install the unit on the pre-set floor supports, minimum 150 mm
height, to ensure sufficient access for the drain pipe connection
to the U-trap and for condensate drain system mounting.
min 150 mm
Note: the mounting is shown for VUT/VUE 250 V(B) EC.
MOUNTING AND WIRING OF THE HEATERS TO THE UNIT WITH A19 CONTROL PANEL
NKP and NKD electric heaters are not included in the delivery set of the air handling unit and are available as specially ordered
accessory.
The heaters are rated for connection to 230V / 50 (60) Hz power supply.
NKP and NKD heaters may be connected to the unit both as a single unit each or jointly.
Prior to connecting the heater to the air handling unit remove the pre-installed plugs from the internal socket connectors.
WARNING!
•
Do not remove the plugs before the heaters are connected to the air handling unit.
•
Make sure to cover the socket connector with the plugs after dismantling of the connecting cable.
•
If only one heater is connected, do not remove the plugs from the other socket connector that is not in use.
•
If the socket connectors are not covered with plugs for any reasons, the ventilation unit does not start during connection to
power supply and the control panel displays DI1 and DI3 errors for NKP and DI1, DI3 and TE5 errors for NKD. Turn the unit
off and cover the socket connectors with the plugs to troubleshoot the errors.
Attach the NKP heater to the air duct connected to the intake air spigot.
The electric heater is connected to the unit via a connecting cable with DB-9F socket connectors connected to the external socket
connectors DB-9F on the unit and the heater.
Attach the NKD heater to the air duct connected to the supply air spigot. Install the air temperature sensor TE5 in the supply air
duct. Keep the minimum distance between the heater and the sensor 1 m.
Connect the electric heater to the unit via a connecting cable with DB-15M socket connectors inserted to the DB-15F external
socket connectors on the unit and the heater.
