Install Drain Joint - MrCool DIY E Star Series Installation & Owner's Manual

SPECIAL CONSIDERATIONS FOR
EXTREME WEATHER
If the unit is exposed to heavy wind:
Install the unit so the 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 airflow. 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 airflow around the
unit.
If the unit is frequently exposed to salty air
(seaside): Use an outdoor unit that is
specially designed to resist corrosion.
Step 2: Install drain joint
Heat pump units require a drain joint if the unit
is elevated. Before bolting the outdoor unit in
place, you must install the drain joint at the
bottom of the unit. NOTE: there are two
different types of drain joints depending on
the type of outdoor unit.
