When the Outdoor Unit is Installed Below the Indoor Unit:
1. Use a conduit, piping set cover, or bundle the (separately) insu-
lated refrigerant piping, the drain hose, and the communications /
connection (power) cable together.
2. Make sure to include some slack in the wiring. Wiring must be
installed in an upwards direction to prevent water from entering the
control box.
3. Secure the conduit, piping set cover, or bundle along the outside
wall using saddles or a similar type of piping support.
4. Seal any openings in the wall that are around the piping.

cable together up to the outdoor unit service valves.
2. Make sure to include some slack in the wiring. Wiring must be
installed in upwards direction to prevent water from traveling into the

3. If necessary, secure the conduit, piping set cover, or bundle along
the outside wall using saddles or a similar type of piping support.
4. Ensure the insulated drain hose from the indoor unit is installed
away from the outdoor unit, and in a downwards direction. If neces-
sary, secure along the outside wall using saddles or a similar type of
support.
5. Seal any openings in the wall that are around the piping.
Always include plenty of insulation on all refrigerant and drain piping to
ensure condensate does not form and cause damage to walls, floors,
etc.
