Flaring Work and Connection of Piping
Check
1. Compare the flared work with the figure by.
2. If a flared section is defective, cut it off and do flaring work
again.
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 only the plastic tubing holder 1, not the holder 2 in
the original position.
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 out-
door unit through the piping hole.
• Do not connect the cable to the indoor unit.
• Make a small loop with the cable for easy connection 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.
If the drain hose is routed inside the room, insulate the hose
with an insulation material* so that dripping from "sweat-
ing"(condensation) will not damage furniture or floors.
*Foamed polyethylene or equivalent is recommended.
