Connecting the drain hose
• In the heating mode, the outdoor unit discharges water due to
defrosting from its drain port and drain hole. Perform drain work if
water drops are a problem.
• In very cold areas where the water in the drain hose could freeze,
do not use a drain hose and the base pan cap with the outdoor unit.
(1) Insert the base pan caps into the drain holes on the bottom of the
outdoor unit.

drain port.
