Installation

Select the best location

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 the spaces indicated by arrows from the wall, ceiling, fence or other obstacles.

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

CAUTION: Install the indoor unit on the wall where the height from the floors more than 2.3m(7.5ft).

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 spaces indicated by arrows around front, back and side of the unit.

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

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

5.Select a place so that the warm air and sound from the air conditioner do not disturb neighbors.

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.

Installation

Fixing Installation Plate(Standard Type)

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 Work and Connection of Piping

Flaring Work and Connection of Piping

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 (5.0ft) 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

Carry out flaring work using flaring tool as shown below.

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

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.

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.
