drain joint into the base pan hole of outdoor unit.
Rotate it 90 degrees to secure it in place.
To install drain joint as shown in Fig. B, insert the
drain joint into the base pan hole of outdoor unit
until it remains fixed with a clicking sound. Connect
the drain joint with an extension drain hose (Locally
purchased), in case of water draining off the
outdoor unit during the heating or cooling mode.
