Connecting the Piping

Indoor
1. Prepare the indoor unit's piping and drain hose for installation through the wall.
2. Remove the plastic tubing retainer(see the illustration
by) and pull the tubing and drain hose away from
chassis.
3. Replace the plastic tubing holder in the original posi-
tion.(Optional)
For right rear piping
1. Route the indoor tubing and the drain hose in the
direction of rear right.
2. Insert the connecting cable into the indoor unit from the
outdoor unit through the piping hole.
• Do not connect the cable to the indoor unit.
• Make a small loop with the cable for easy connec-
tion later.
3. 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 uper side
can cause drain pan to overflow inside the unit.
CAUTION: If the drain hose is routed inside
the room, insulate the hose with an insulation
material* so that dripping from
"sweating"(condensation) will not damage fur-
niture or floors.
*Foamed polyethylene or equivalent is recom-
mended.
