Installing the Indoor Unit

Hazardous Service Procedures!
The maintenance and troubleshooting procedures recommended in this section of the manual
could result in exposure to electrical, mechanical or other potential safety hazards. Always
refer to the safety warnings provided throughout this manual concerning these procedures.
Disconnect all electrical power including remote disconnect and discharge all energy storing
devices such as capacitors before servicing. Follow proper lockout/tag out procedures to
ensure the power can not be inadvertently energized. When necessary to work with live
electrical components, have a qualified licensed electrician or other individual who has been
trained in handling live electrical components perform these tasks. Failure to follow all of the
recommended safety warnings provided, could result in death or serious injury.

Mounting Location

1. Confirm the mounting location with the customer. Keep in mind the basic installation guidelines
on page 12.
2. Place the wall-mounting frame on the wall and check that it is level. Mark the screw holes to be
drilled, ensuring they are in a place with adequate support.
a. It is equally important to assure the mounting surface (i.e. wall) is flat. Use a
straight edge to assure the section of the mounting surface, in which the unit will be
secured, is neither concave or convex.
b. For corrugated walls, indoor unit installation is recommended on a solid backing
affixed to the wall.
3. Drill the holes on the wall according to the selected marks. If the mounting bracket cannot
be directly affixed to wall studs or other solid backing, wall anchors shall be used to secure
mounting bracket.
4. Attach the wall-mounting frame with the supplied tapping screws and check to make sure it is
firmly attached. If any of the screws or anchors are loose, select another point on the frame to
re-drill and attach securely.
5. Be sure that the wall-mounting frame has been secured firmly enough to withstand the weight
of the unit. The weight should be evenly distributed to the fasteners.
6. Prior to leaving the job site, seal any and all openings in the wall caused by the installation
process.
