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 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.

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.
