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 illustration on the right) and pull the tubing and drain hose away from chassis.

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 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 on the lowest side of the bundle. Locating on the Upper side can cause the conden- sation to overflow in the drain pan inside the indoor 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.
