Special considerations for extreme weather
If the unit is exposed to heavy wind, install unit so that air outlet fan is at a 90° angle to the
direction of the wind. If needed, build a barrier in front of the unit to protect it from extremely
heavy winds. See figures below.
If the unit is frequently exposed to heavy rain or snow
Build a shelter above the unit to protect it from rain or snow. Be careful not to obstruct airflow
around the unit.
STEP 2: INSTALL THE DRAIN JOINT
1. Fit the rubber seal on the end of the drain joint that will connect to the outdoor unit.
2. Insert the drain joint into the hole in the base pan of the unit.
3. Rotate the drain joint 90° until it clicks in place facing the front of the unit.
4. Connect a drain hose extension (not included) to the drain joint to redirect water from the unit
during heating mode.

NOTE
In cold climates, make sure that the drain hose is as vertical as possible to ensure swift
water drainage. If water drains too slowly, it can freeze in the hose and flood the unit.
