• If a wall mount installation is required, the installation
bracket should meet the requirement in the installation
bracket diagram and the wall should be able to support
the installation.
• Be sure there are no obstacles blocking air discharge.
The installation wall should be constructed of brick, con-
crete or another surface of equal strength to hold the
unit safely. Make sure the connections to the wall,
bracket and unit are firmly seated and there are no ob-
structions to the airflow.
Anchoring the outdoor unit
The unit should be tightly anchored, horizontally, with a nut
and bolt ( 10 or 8) on a concrete or similarly rigid, stable
surface.

Drain joint installation
NOTE: Drain joints differ slightly according to the different
outdoor units. Inspect your unit and use the installation in-
structions for your specific unit.
For drain joints with seals (Figure 15A):
• Slide the seal onto the drain joint and insert into the
base pan hole of the outdoor unit. Rotate 90° to secure
(see Figure 16).
For drain joints without seals (Figure 15B):
• Insert the drain joint into the base pan hole of the out-
door unit until it remains fixed, accompanied by a click-
ing sound.
NOTE: For protection against water condensation off the out-
door unit during heating mode, connect the drain joint with an
extension drain hose (provided by the installer).
