Outdoor Unit Installation

SPECIAL CONSIDERATIONS FOR

EXTREME WEATHER

If the unit is exposed to heavy wind:

Install unit so that 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 air ﬂow. 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 air ﬂow around the unit.

Step 2: Install drain joint

Heat pump units require a drain joint ONLY if the

unit is elevated. DO NOT install if the unit is sitting

on the ground or concrete pad.

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.

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 doesn’t 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.
