Connecting the 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.
