Outdoor Unit Installation 15
5.1.1.
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. 5.2 and Fig. 5.3 below.

If the unit is frequently exposed to heavy rain or snow:
Build a shelter above the unit it 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):
Distance to Wind Baffle must be >500mm
Step 2: Install drain joint
AC 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. 5.4-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. 5.4-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.

CAUTION
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.
Step 3: Anchor outdoor unit
The outdoor unit can be anchored to the ground or to a wall-mounted
bracket.
