location for the unit.
Proper installation locations meet the following
standards:
; Meets all spatial requirements shown in
Installation Space Requirements above.
; Good air circulation and ventilation
; Firm and solid—the location can support
the unit and will not vibrate
; Noise from the unit will not disturb others
; Protected from prolonged periods of direct
sunlight or rain
; Where snowfall is anticipated, take
appropriate measures to prevent ice
buildup and coil damage.

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.

STEP 2: INSTALL 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. A), do the following:
Fit the rubber seal on the end of the drain
joint that will connect to the outdoor unit.
Insert the drain joint into the hole in the base
pan of the unit.
Rotate the drain joint 90° until it clicks in place
facing the front of the unit.
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:
Insert the drain joint into the hole in the base
pan of the unit. The drain joint will click in
place.
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.
