7.2 Install Drain Fitting

Heat pump units require a drain fi tting. Before bolting the outdoor unit in place,
you must install the drain fi tting at the bottom of the unit. Note that there are two
diff erent types of drain fi ttings depending on the type of outdoor unit.
If the drain fi tting comes with a rubber seal (see Figure 23, pos. A ), do the
following:
1. Fit the rubber seal on the end of the drain fi tting that will connect to the
outdoor unit.
2. Insert the drain fi tting into the hole in the base pan of the unit.
3. Rotate the drain fi tting 90° until it clicks in place facing the front of the unit.
4. Connect a drain hose extension (not included) to the drain fi tting to redirect
water from the unit during heating mode.
If the drain fi tting doesn't come with a rubber seal (see Figure 23, pos. B), do the
following:
1. Insert the drain fi tting into the hole in the base pan of the unit. The drain
fi tting will click in place.
2. Connect a drain hose extension (fi eld supplied) to the drain fi tting 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.
