Step 3 - Condensate Drain Installation
NOTE: Install drains must meet local sanitation codes.
Install the outdoor unit drain joint
Fit the seal into the drain joint, then insert the drain joint into the base
pan hole of the outdoor unit. Rotate 90° to securely assemble them.
Connect the drain joint with an extension drain hose to avoid condensate
from draining off the outdoor unit during the heating mode.

ensure swift water drainage. If water drains too slowly, it can freeze
in the hose and flood the unit.
