Position the Unit
Important.
The unit is heavy. Exercise caution while putting the unit in place to prevent
damage to the unit or personnel.
The unit must be installed in a level position. An inclination of more than 6-7 mm (± 1°) could cause
the condensation tray to overflow.
Lift the unit from below with lifting equipment or tools, and then move the unit to the wall. Use the
screws (installer supplied) to affix the unit on the wall. Generally, this is done by following these steps:
1.
Position the unit next to the wall.
2.
Attach a single mounting screw and adjust to ensure the unit is level.
3.
After the unit is level, attach the remaining mounting screws.
Seal the Joints between Units and Wall
To prevent moisture from getting in and air leaking out, coat the joint between the rear panel of the
unit and the wall with a layer of silicone sealant (installer provided, see Table 7: Installer Supplied
Materials, item 1)
Duct Work
All duct work shall be properly sized for the airflow requirement of the equipment. A minimum of 1" of
fiberglass insulation or equivalent is recommended to prevent energy loss and moisture build up. All

When no supply or return duct are used, metal grilles shall be deployed on all supply and return
openings.
