Installation Instructions – Outdoor
Unit
Step 1: Select installation location
Before installing the outdoor unit, you must
choose an appropriate location. The following
are standards that will help you choose an
appropriate location for the unit.
Proper installation locations meet the
following standards:
o
Meets all spatial requirements shown in
Installation Space Requirements (
Fig. 4.1
)
o
Good air circulation and ventilation
o
Firm and solid—the location can support the
unit and will not vibrate
o
Noise from the unit will not disturb others
o
Protected from prolonged periods of direct
sunlight or rain
DO NOT
install unit in the following locations:
Near an obstacle that will block air inlets
and outlets
Near a public street, crowded areas, or
where noise from the unit will disturb others
Near animals or plants that will be harmed
by hot air discharge
Near any source of combustible gas
In a location that is exposed to large
amounts of dust
In a location exposed to a excessive amounts
of salty air

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.
See
Fig. 4.2
and
Fig. 4.3
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.
If the unit is frequently exposed to salty air
(seaside):
Use outdoor unit that is specially designed to
resist corrosion.
Step 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 different types of drain joints
depending on the type of outdoor unit.
If the drain joint comes with a rubber seal
(see
Fig. 4.4 - 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. 4.4 - 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.

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.
