7.2 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
diff erent types of drain joints depending on the type of outdoor unit.
If the drain joint comes with a rubber seal (see Figure 22, pos. 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 Figure 22, pos. 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 (fi eld supplied) to the drain joint to redirect
water from the unit during heating mode.
NOTICE
 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.
