Step 2: Install drain joint (Heat pump unit only)
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.

IN COLD CLIMATES
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.
