INSTALLATION ON HORIZONTAL SURFACE
CONDENSATE DRAINAGE
The unit is equipped with two pans for removal of the condensed water generated during the operation of the heat pump heat-transfer
units.
To arrange a condensate drain connect the drain pipes and the U-traps to the sewage system using plastic or rubber pipes. The pipes must
be installed at the minimum downward gradient of 3o.
Fill the U-trap with water before starting the unit. During the operation make sure to maintain the sufficient water level in the U-trap and
enable unobstructed water flow from the unit into the sewage system. Failure to do so will result in accumulation of condensate during the
heat pump operation which may cause unit failure and water ingress into the serviced spaces.
SAFETY PRECAUTIONS
The unit must be mounted to a rigid and stable structure.
The unit must be suspended using anchor bolts. Make sure that the base structure is capable of sustaining the unit weight. Otherwise reinforce
the mounting location with beams or similar elements.
If the bolts used for the unit mounting are too short the unit can generate abnormal noise and resonate with the ceiling. Use bolts of sufficient
length to prevent resonance.
If the abnormal noise is generated at the spiral air duct joint replace the spiral air duct with a flexible one to prevent resonance. Flexible anti-
vibration connectors are another alternative for dealing with resonance.
ON COMPLETING THE UNIT INSTALLATION BALANCE THE AIR FLOW IN THE SUPPLY
AND EXHAUST VENTILATION SYSTEM.
THE SUPPLY AIR FLOW MAY NOT EXCEED THE EXHAUST AIR FLOW BY MORE THAN 15 %.
