16 Multi type Air Conditioner

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.

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.

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

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.

3. After pull down this panel a bit, and separate connecting wire with product.

Remove cover pipe and cover side

1. Remove two screws(for fixing cover pipe)

2. Pull up the cover side of desired connecting direction, then cover side is separated.

3. In case of connecting direction is left or right, path through the hole of cover side.

CAUTION: After removing the pipe hole, cut the burr for safety.

When connecting pipe path through rear wall, don’t remove the hole.

NOTICE

5. Check the fixed product with light power.

6. Look at suited horizon by horizontal meter on the horizontal setting line, and Fix lightly the map by adhesive tape.

7. Drill the piercing part for connecting pipe as diameter 50mm. (In case of piercing rear surface)

Refer to No. 5 on this page when making a hole in the wall.

8. First, Drive the two points of the upper parts by screws. (Leave 10mm for hanging product)

9. Drive the lower parts after facing the hole of product with plastic anchors, and fix completely the upper screws.

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.

Flaring Work and Connection of Piping

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.
