Flaring Work
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure.
Cut the pipes and the cable.
1.Use the piping kit accessory or the pipes purchased locally.
2.Measure the distance between the indoor and the outdoor unit.
3.Cut the pipes a little longer than measured distance.
4.Cut the cable 1.5m longer than the pipe length.
Burrs removal
1.Completely remove all burrs from the cut cross section of pipe/tube.
2.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.

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 only the plastic tubing holder 1, not 
the holder 2 in the original position. 
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.
Drain hose
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 "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.
Press the lower left and right sides of the unit against the installation plate until the hooks engage into their slots(clicking sound).
Connecting the piping to the indoor unit and drain hose to drain pipe.
1.Align the center of the pipes and sufficiently tighten the flare nut by hand.
2.Tighten the flare nut with a wrench.

2.Wrap the area which accommodates the rear piping housing section with vinyl tape.
3.Bundle the piping and drain hose together by wrapping them with vinyl tape for enough to cover where they fit into the rear piping housing section.
