The drainage pipe is used to drain the water from the
unit. Incorrect installation can cause damage to the unit
and other material damage.

CAUTION DANgER
– Insulate all of the pipes to prevent
condensate from forming, which could
cause water damage.
– If the drainage pipe is bent or not installed
properly, the water can escape and cause
the float switch to malfunction.
– In HEAT mode, the outdoor unit discharges
water. Make sure that the drainage pipe is in
a suitable area to avoid water damage and
slipping hazards caused by the discharge
water freezing.
– DO NOT pull the drainage pipe, as this could
detach it.

– When using an extension for the drainage
pipe, tighten the connection on the inside
with an additional protection pipe to stop it
from coming loose.
– The drainage pipe must slope by at least
1/100 to prevent the water from flowing back
into the air conditioner.
– To stop the pipe from bending, fix the
suspension elements every 1-1.5 m.
– Incorrect installation can cause the water to
flow back into the unit.
