Indoor unit

•Do not have any heat or steam near the unit.

•Select a place where there are no obstacles in front of the unit.

•Make sure that condensation drainage can be conveniently routed away.

Do not install near a doorway.

•Ensure that the space around the left and right of the unit is more than "A". The unit should be installed as high on the wall as possible, allowing a minimum of "B" from ceiling.

•Use a stud finder to locate studs to prevent unnecessary

damage to the wall.

Rooftop Installations:

•If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the roof structure and anchoring method are adequate for the unit location.

•Consult local codes regarding rooftop mounting.

HowtoFixInstallationPlate

The wall you select should be strong and solid enough to prevent vibration

1. Mount the installation plate on the wall with four type A screws. If mounting the unit on a concrete wall, use anchor bolts.

•Mount the installation plate horizontally by aligning the centerline using a level.

2.Measure the wall and mark the centerline. It is also important to use caution concerning the location of the installation plate-routing of the wiring to power outlets is through the walls typically. Drilling the hole through the wall for piping connections must be done safely.

Flaring work and connection of piping

Flaring work and connection of piping

Flaringwork

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.

Copper		Slanted Uneven Rough
pipe	90°

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.

Putting nut on

•Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube having completed burr removal. (not possible to put them on after flaring work)

Flaring work and connection of piping

For right rear piping

Route the indoor tubing and the drain hose in the direction of rear right.

Connecting the pipings to the indoor unit and drain hose to drain pipe.

•Align the center of the pipes and sufficiently tighten the flare nut by hand.

Drain hose

Indoor unit tubing

Flare nut Pipes

• Tighten the flare nut with a wrench.

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.

NOTE: 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.

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.
