Step 2 - Install the Drain Joint
NOTE: Before bolting the outdoor unit in place, you must install the drain joint at the bottom of the unit. For units with a base pan built-in
(with multiple holes for proper draining during defrost), the drain joint is not needed to be installed.
1. Locate the outdoor unit’s base pan hole.

2. Fit the rubber seal on the end of the drain joint that connects to the outdoor unit.

3. Insert the drain joint into the hole in the base pan of the unit. The drain joint will “click” in place.
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, ensure 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.
