Outdoor Unit Installation
SPECIAL CONSIDERATIONS FOR
EXTREME WEATHER
If the unit is exposed to heavy wind:
Install the unit so the air outlet fan is at a
90° angle to the direction of the wind. If
needed, build a barrier in front of the unit
to protect it from extremely heavy winds.
Ensure the wind barrier does not block
necessary airflow. See Fig. 6.2 and Fig. 6.3
below.
If the unit is frequently exposed to heavy
rain or snow: Build a shelter above the unit
to protect it from the rain or snow. Be
careful not to obstruct airflow around the
unit.
If the unit is frequently exposed to salty air
(seaside): Use an outdoor unit that is
specially designed to resist corrosion.
Step 2: Install drain joint

DRAINAGE 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.

If the drain joint comes with a rubber seal (see
Fig. 6.4 - 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 does not come with a rubber seal
(see Fig. 6.4 - 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
Wind Baffle
Heat pump units require a drain joint if the unit
is elevated. Before bolting the outdoor unit in
place, you must install the drain joint at the
bottom of the unit. NOTE: there are two
different types of drain joints depending on
the type of outdoor unit.
