Outdoor Condensate Drainage
During heating operation, the condensate and defrosting
water should be drained out reliably through the drain hose.
Install the outdoor drain connector in a Φ25 h ole on
the base plate and attach the drain hose to the connector
so that the waste water formed in the outdoor unit can be
drained out. The hole diameter 25 must be pl ugged.
