4.4 Install drain joint
Heat pump units require a drain joint. Before bolting the
outdoor unit in place, you must install the drain joint at the
bottom of the unit. Note that there are two different types
of drain joints depending on the type of outdoor unit.
• If the drain joint comes with a rubber seal (see
Fig. A ), do the following:
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.
• If the drain joint doesn't come with a rubber seal
(see Fig. B ), do the following:
1. Insert the drain joint into the hole in the base pan of the
unit. The drain joint will click in place.
2. Connect a drain hose extension (not included) to the
drain joint to redirect water from the unit during heating
mode.
