Installation

Indoor unit

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

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

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

4. Do not install near a doorway.

5. Ensure that the interval between a wall and the left (or right) of the unit is more than 10cm.The unit should be installed as high as possible on the wall, allowing a minimum of 20cm from ceiling.

6. Use a stud finder to locate studs to prevent unnecessary damage to the wall.

Outdoor unit

1. If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that heat radiation from the condenser is not restricted.

2. Ensure that the space around the back and sides is more than 30cm.The front of the unit should have more than 70cm of space.

3. Do not place animals and plants in the path of the warm air.

4.Take the weight of the air conditioner into account and select a place where noise and vibration are minimum.

5. Select a place where the warm air and noise from the air conditioner do not disturb neighbors.

Installation

Fixing Installation Plate

• Drill the piping hole with a ø70mm hole core drill. Drill the piping hole at either the right or the left with the hole slightly slanted to the outdoor side.

Drill a Hole in the Wall

5-7mm

(3/16"~5/16")

Indoor

WALL

Outdoor

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

1. Mount the installation plate on the wall with

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 W ork

Main cause for gas leakage is due to defect in flaring work.Carr y out correct flaring wor k 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.

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

1. Firmly hold copper pipe in a die in the dimension shown in the table below.

2. Carry out flaring work with the flaring tool.

Installation

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.

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.

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.

3.When extending the drain hose at the indoor unit, install the drain pipe.

Wrap the insulation material around the connecting portion.

1. Overlap the connection pipe insulation material and the indoor unit pipe insulation material. Bind them together with vinyl tape so that there may be no gap.

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.
