Mounting of Indoor Unit

drilling Piping Hole in the Wall
Follow the left or right piping clearance recommendations as shown in Figure 9 and 10.
1. Using a 2-5/8 (ø 65mm) inch hole core drill bit, drill a hole at either the right or left
side of the wall mounting (Figure 13).
• The slant of the hole should be 3/16" to 5/16" from level with the slant being upward
on the indoor unit side and downward on the outdoor unit side.
2. Finish off the newly drilled hole as shown with bushing and sleeve covering.
• Sleeve and bushing prevents damage to the tubing/bundling of the piping.
Mounting the Indoor unit to the Installation Plate
1. Hook the indoor unit onto the upper portion of the installation plate (Figure 14).
2. Engage the hooks at the top of the indoor unit with the upper edge of the installation
plate.
• Ensure that the hooks are properly seated on the installation plate by moving it left
and right.
3. Move the bottom of indoor unit towards the installation plate to anchor to wall (Figure
145).
• It helps to press the lower left and right sides of the unit against the installation plate
until the hooks engage into their slots.
• You will hear a clicking sound as the bottom attaches to the installation plate
successfully.
4. Finish by inserting and tightening two type "C" screws into the bottom of the installa-
tion plate (Figure 16).
• Pay attention to the positioning of the piping through any wall as shown in the figure,
as you insert the screws to the indoor unit.
Preparing for Piping/electrical Connection
1. To prepare indoor unit for piping, disengage bottom on indoor unit from installation
plate by reversing step 3 from previous procedure.
• This step will separate the indoor unit's bottom side from the wall mount in order
to route drain hose correctly. See Figure 17 for a reference of the rear view of the
indoor unit.
2. Swing drain hose holder (L-bracket) out and anchor as shown in Figure 15,
against installation plate.
3. Optionally, go to Refrigerant Piping Connections section of this manual to
continue with piping connections to the indoor unit.
4. Optionally, go to Electrical Connections section of this manual to continue
with conduit/electrical wiring to the indoor unit.
