Hang the unit from the hangers and make sure that the hangers
are engaged correctly as shown at picture below.
4
Do NOT install the unit tilted. If the unit is tilted against the
direction of the condensate flow (drain piping side raised), it will
cause water to drip.
5
Please check, if the unit is levelled with a water level (a) or a
water filled plastic tube (b).

Connecting water piping
NOTICE
Do not use excessive force when connecting the piping.
This could deform the unit piping. Deformation of the piping
can cause the unit to malfunction.
CAUTION
Valves should always be used to control the water
circulation in the unit. The valve should be of the NC
(normally closed) type so that the valves are closed when
the unit is not operating. This will prevent condensate
water from being produced.
