Indoor Unit Installation (cont.)
6. Hang Indoor Unit
•
Bundle the refrigeration lines, drainage hose, and
wiring conduit attached to the indoor unit and
wrap them securely for enough length to extend
through the piping hole to the exterior of the
building. (Note: leave remainder unwrapped to
allow for remaining steps in installation of the
outdoor unit and connecting the indoor unit to the
outdoor unit.)
•
Carefully push bundled lines through the piping
hole.
•
Hang the unit on the wall by hooking the mounting
slots of the unit over the upper tabs of the rear
panel.
•
Check to make sure the unit is properly secured --
it should feel firmly attached to the wall, and you
should not be able to slide it to the right or left.

Outdoor Unit Installation
1. Connect Refrigeration Lines to Bundled Lines from Indoor Unit
•
Use standard A/C practices to attach the connection pipes to the proper pipes of the
bundled lines coming through the wall from the indoor unit.
•
Tighten the flare nut of the connection pipes using a spanner
and torque wrench. (see diagram)
•
Note: Do not over-tighten flare nuts, or the connection may be
damaged.
2. Insulate/Bundle Refrigeration Lines and Wiring
•
Individually insulate all refrigeration lines and condensation drainage hose to ensure that
they do not sweat. This will help to maintain the unit at its proper capacities.
•
Once all lines have been properly insulated, bundle the refrigeration lines with the wiring
conduit and wrap securely to complete the run to the outdoor unit.
•
Note: The condensation drainage hose should be left free of the bundled lines in order to
drain properly.
3. Install Outdoor Condensation Drainage Hose (Heat Pump Models Only)
•
When the heat pump unit is heating or defrosting, wastewater forms in
the outdoor unit. This can be drained off using the outdoor drain elbow
and hose provided.
•
Insert the drain elbow into the hole on the base plate as shown.
•
Joint the drain hose to the elbow and turn so that the water
drains in the desired location.
