GENERAL INSTALLATION GUIDELINES
Indoor Unit Mounting
Mounting the Indoor Unit to the Installation Plate
1. Position the indoor unit onto the top portion of the installation plate.
2. Engage the hooks at the top of the indoor unit with the top edge of the installation plate
(number of hooks depends on model type).
3. Ensure the hooks are properly seated on the installation plate by shaking the indoor unit left
and right.
dures are complete.
4. Retain a space between the indoor unit and the installation plate by unsnapping the piping
holder and using it as a space holder.
5. Carefully guide the refrigerant piping and drain piping through the access hole.
• Pay attention to the positioning of the piping through the wall.
6. Close the piping holder by snapping it back into place on the indoor unit.
7. Push the bottom of indoor unit towards the installation plate.
• Press the lower left and right sides of the unit against the installation plate until the clips
engage into their connection points.
• Clicking sounds could be heard as the bottom of the indoor unit attaches to the installation
plate successfully.
The indoor unit can fall from the wall if it is not properly installed and secured to the installation plate.
• To avoid a gap between the installation plate and the wall, ensure the screws are correctly
and fully secured.
• To prevent condensate from forming due to an inflow of outdoor air, before indoor unit installa-
tion is finished, completely seal the piping access hole in the wall.
Preparing for Piping / Electrical Connections
1. To prepare indoor unit for piping and electrical installation, disengage the bottom of the indoor unit from installation plate, if those procedures
have been performed.
2. Unsnap the piping / drain hose holder out from the indoor unit. Prop it open between the indoor unit and installation plate to separate the
bottom of the indoor unit from the wall. This will allow for more working space.
