Flaring
Work
Main cause for refrigerant leakage is due to defect in the flaring work. Carry out correct flaring work using the following procedure.
Cut the pipes and the cable.
•Use the piping kit accessory or pipes purchased locally.
•Measure the distance between the indoor and the outdoor unit.
•Cut the pipes a little longer than the measured distance.
•Cut the cable 1.5m longer than the pipe length.

Burr removal
•Completely remove all burrs from the cut cross section of pipe/tube.
•Put the end of the copper tube/pipe in a downward direction as you remove burrs in order to avoid dropping burrs into the tubing.

•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 hose away from chassis.
•Replace the plastic tubing holder in the original position.
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 upper side can cause drain pan to overflow inside the unit.
Tubing holder
CAUTION: When install, make sure that the remaining
parts must be removed clearly so as not to damage the piping and drain hose, especially power cord and connecting cable.
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 connection later.

NOTICE 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 furniture or floors.
*Foamed polyethylene or equivalent is recommended.
4.Indoor unit installation
•Hook the indoor unit onto the upper portion of the installation plate.(Engage the two hooks of the rear top of the indoor unit with the upper edge of the installation plate.) Ensure that the hooks are properly seated on the installation plate by moving it left and right.
