Connection of the Pipes
Preparing the indoor unit’s piping and drain
hose for installation through the wall.
Remove the plastic tubing retainer (see
illustration below) and pull the tubing
and drain line away from chassis.
Replace the plastic tubing holder in the original
position.
FOR RIGHT REARPIPING:
Route the tubing and the drain hose straight
backwards.
Insert the connecting wiring cable into the
indoor unit from the outdoor unit through
the piping hole.
1
Do not connect the cable to the indoor unit.
2
Make a small loop with the cable for easy
connection later.
NOTE:
Wiring must comply with local and NEC
codes. The interconnecting wiring between
indoor and outdoor units of this system must be
18–4 wiring, 18-gauge (minimum), 300-volt rating,
type SJO-WA or STO-WA.
Tape the tubing, drain hose and the connecting
cable. Be sure that the drain hose is located at
the lowest side of the bundle. Locating at the
upper side can cause drain pan to overflow
inside the unit.
NOTE:
If the drain hose will be routed in the room,
insulate the hose with an insulation material
*
so
that dripping from “sweating” (condensation) will
not damage furniture or floors.
*
Foamed polyethylene or equivalent is
recommended.
