GENERAL INSTALLATION GUIDELINES
Drilling the Piping Hole in the Wall
Use caution when drilling holes through walls. Drilling into power wiring in the wall can cause seri-
ous bodily injury or death.
Follow the left or right piping clearance recommendations.
1.
Using a 2-5/8 (ø65mm) inch hole core drill bit, drill a hole at either the right or left side of
the wall mounting. The hole must slant 3/16” to 5/16” from level (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.

WARNING
•
Mounting hardware must be securely installed to prevent the chassis falling from its installation location. There is risk of injury or property
damage from falling equipment.
•
When choosing a location for the wall mount plate, be sure to take into consideration routing of wiring for power outlets within the wall.
Touching wiring can cause serious bodily injury or death.
•
Installation work must be performed by trained personnel and in accordance with all local or other applicable codes. There is risk of injury to
personnel from incorrect installation.
Note:
•
Ensure the unit is properly installed. Incorrectly installed units can result in degraded performance or an inoperative unit / system.
•
Mounting hardware must be securely installed to prevent the chassis falling from its installation location. There is risk of property damage
from falling equipment.
• Use a level indicator to ensure the installation plate and chassis are installed on a level plane.
•
If the unit is installed near a body of water, certain components are at risk of being corroded. Appropriate anti-corrosion methods must be
taken for the unit and all components.
General Guidelines — Wall-Mounted
Indoor Units
Wall-mounted indoor units have several options on how the piping
and wiring can be routed (see figure at right). Whichever way the
piping and wiring are routed out of the indoor units, the mounting
wall on which the indoor unit is installed must be strong and solid
enough to protect it from vibration.
•
Mount the installation plate on the wall using the Type “A”
screws. If mounting the unit on concrete, consider using anchor
bolts.
•
Always mount the installation plate horizontally. Measure the wall
and mark the center line using thread and a level.
