3. Piping can easily be made by lifting the indoor unit with a cushioning material between the indoor unit and the wall. Get it out after finish piping.

4. Push the lower part of the indoor unit up on the wall, Then move the indoor unit from side to side, up and down to check if it is hooked securely.

Cushioning material

Piping and wrapping

1. Bundle the tubing, connecting cable, and drain hose with tape securely and evenly as shown in the sideward figure.

2. Because the condensed water from rear of the indoor unit is gathered in ponding box and is piped out of room, do not put

Attention

1. Connect the indoor unit first, then the outdoor unit.

2. Do not allow the piping to let out from the back of the indoor unit.

3. Be careful not to let the drain hose slack.

4. Both of the auxiliary piping should be heat insulation.

5. Be sure that the drain hose is located at the lowest side of the bundle. Locating

at the upper side may cause drain pan to overflow inside the unit.

6. Never intercross nor intertwist the power wire with any other wiring.

7. Run the drain hose sloped downward to drain out the condensed water

smoothly.

Indoor unit installation

Outdoor unit installation

1. Install the outdoor part of the unit on a rigid surface to avoid excess noise and vibration.

2. Direct the air vent toward an area without obstacles.

3. Install the unit at the site where it is exposed

especially in areas where it is frequently windy.

4. If the installation site is exposed to heavy winds, such as in coastal areas, place the unit along the widest part of the wall or use protective plates.

5. If suspended installation is needed,

purchase kit No.EA140S from your local or servicer. The installation bracket should accord with technique

requirement in the installation bracket diagram. The installation wall should be solid brick, concrete or the same intensity construction, or action to reinforce, damping supporting should be taken. The connection between bracket and wall, bracket and the air conditioner should be firm, stable and reliable.

6. Be sure there is no obstacle which blocks radiating air, including schrubs or bushes.

Refrigerant piping connection

Unit comes with 16.4 feet tubing bundle. It is not recommended to cut. If too long, loop for excess.

Note: Keep original bend so not kinking of the tube occurs.

Flaring work

Main cause for refrigerant leakage is due to defect in the flaring work.

Carry out correct flaring work using the following procedure:

1. Cut the pipes and the cable.

A) Use the piping kit accessory or

pipes purchased locally.

B) Measure the distance between the

indoor and the outdoor unit.

C) Cut the pipes a little longer than the

measured distance.

D) Cut the cable 4.92 feet longer than

the pipe length.

2. Burr removal

A) Completely remove all burrs from

the cut cross section of pipe/tube.

B) 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.

3. Put nut on.

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

Caution

After the confirmation of the above conditions, prepare the wiring as follows:

1. Never fail to have an individual power circuit specifically for the air conditioner. As for the method of wiring, be guided by the circuit diagram posted on the inside of control cover.

2. The screws which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could cause burn-out of the wires.)

3. Specification of power source.

4. Confirm that electrical capacity is sufficient.

5. See to that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate.

6. Confirm that the cable thickness is as specified in the power source specification.

7. Always install an earth leakage circuit breaker in a wet or moist area.

8. The following would be caused by voltage drop: vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance of the normal function of the overload protector.

9. The means for disconnection from a power supply shall be incorporated in the fixed wiring and have an air gap contact separation of at least 0.12 inch in each active (phase) conductors.

Air purging

Air and moisture in the refrigeration system have undesirable effects as indicated below:

1. Pressure in the system rises.

2. Operating current rises.

3. Cooling or heating(only for

models with heating function) efficiency drops.

4. Moisture in the refrigerant circuit

may freeze and block capillary tubing.

Electrical work and air purging

5. Water may lead to corrosion of parts in the refrigeration system.

Therefore, the indoor unit and tubing

between the indoor and outdoor unit must apply leakage test and be evacuated to remove any noncondensables and moisture from the system.

Air purging with vacuum pump

1. Check that each tube(both liquid and gas side tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Remove the service valve caps from both the gas and the liquid side on the outdoor unit. Note that both the liquid and the gas side service valves on the outdoor unit are kept closed at this stage.

2. When relocating the unit to another place, perform evacuation using vacuum pump.

3. Pipe length and refrigerant amount:

Caution in handling the packed valve integrated in the outlets of outdoor unit.

1. Operation of opening packed valve: Open the valve stem until it hits against

the stopper. Do not try to open it further.

2. Operation of closing packed valve: Securely tighten the valve stem with a special

tool. Then securely tighten the valve stem cap with a spanner or the like. Refer to

for valve stem cap tightening torque tightening torque table in page 17

Electrical safety

Perform the electric safety check after completing installation:

1. Insulated resistance: The insulated resistance must be more than 2M .

2. Grounding work: After finishing grounding work, measure the grounding resistance by visual detection and grounding resistance tester. Make sure the grounding resistance is less than 4 .

3. Electrical leakage check (performing during test running): During test operation after finishing installation, the serviceman can use the electric probe and multimeter to perform the electrical leakage check. Turn off the unit immediately if electrical leakage happens. Check and find out the solution ways till the unit operates properly.

Gas leak check

Soap water method

Apply a soap water or a liquid neutral detergent on the indoor unit connection or outdoor unit connections by a soft brush to check for leakage of the connecting points of the piping. If bubbles come out, the pipes have leakage point.
