CONDENSATE DRAIN
The drain pan is equipped with drain pipes for condensate removal
outside the unit.
Connect the drain pipe, the U-trap (not included into the delivery set) and
a sewage system with metal, plastic or rubber drain hoses, fig. 8.
While laying the hoses provide the slope downward min. 3%.
Fill the system with water prior to connecting it to power supply. The
U-trap must always be filled with water.
Before starting the unit fill the drain system with water and keep the
U-trap always filled with water. Provide free drainage for the condensed
water, otherwise it is accumulated inside the unit which may result in the
equipment damage and condensate outflow to the room.
The condensate drain system is suitable for indoor frost-free
application with the ambient temperature above 0°C!
If the expected ambient temperature is below 0°C provide heating
for the drain system.
WARNING
In case of several unit mounting connect each unit to an individual U-trap. Direct condensate discharge with no connection to
the drain system is not allowed.

The unit is suspended using threaded rods and threaded dowels. The unit
must be mounted on the even surface to avoid the unit casing distortion and
operation disturbances. The installation place must have connection to the
sewage drain system.
While planning the ductwork layout avoid too long air duct sections,
numerous bends and reducers because it may reduce air flow.
The mounted air ducts must not be deformed.
While planning the ductwork layout avoid too long air duct sections,
numerous bends and reducers because it may reduce air flow.
The mounted air ducts must not be deformed.
Provide airtight connection of the air ducts to the unit spigots and fittings.
Install straight air ducts on both sides of the unit to minimize aerodynamic
resistance caused by air flow turbulence, the minimum air duct section
length is equal to 1 time air duct diameter on the inlet side and 3 time air
duct diameters on the outlet side.
In case of insufficient length or no air ducts cover the unit spigots with a
protecting grille or any other protecting device with maximum mesh width
12.5 mm to prevent ingress of foreign objects inside the unit and prevent
contact with fans of the unit.
Prior to starting mounting make sure the mounting surface has sufficient
load capacity matching the unit weight. Otherwise reinforce the installation
place with beams.
Use threaded rods of sufficient length to avoid possible resonance with a
mounting surface.
If the connection point of the spiral seam air duct to the unit is supposed
to be a source of noise generation, replace a spiral seam air duct with a
flexible air duct. The flexible anti-vibration connectors (specially ordered
accessories) may be also useful.
