2. Selecting the installation location

2.1. Indoor unit

• Where airflow is not blocked.

• Where cool air spreads over the entire room.

• Where it is not exposed to direct sunshine.

• At a distance 1 m or more away from your TV and radio (to prevent picture from being distorted or noise from being generated).

2.2. Outdoor unit

• Where it is not exposed to strong wind.

• Where airflow is good and dustless.

• Where it is not exposed to rain and direct sunshine.

• Where neighbours are not annoyed by operation sound or hot air.

• Where rigid wall or support is available to prevent the increase of operation sound or vibration.

• Where there is no risk of combustible gas leakage.

• When installing the unit at a high level, be sure to fix the unit legs.

• Where it is at least 3 m away from the antenna of TV set or radio. (Otherwise, images would be disturbed or noise would be generated.)

• In a place as far away as possible from fluorescent and incandescent lights (so the infrared remote control can operate the air conditioner normally).

• Where the air filter can be removed and replaced easily.

Warning:

Mount the indoor unit into a ceiling strong enough to withstand the weight of the unit.

The indoor models should be installed the ceiling over than 2.5 m from floor.

3. Selecting an installation site & Accessories

• Select a site with sturdy fixed surface sufficiently durable against the weight of unit.

• Before installing unit, the routing to carry in unit to the installation site should be determined.

• Select a site where the unit is not affected by entering air.

• Select a site where the flow of supply and return air is not blocked.

• Select a site where refrigerant piping can easily be led to the outside.

• Select a site which allows the supply air to be distributed fully in room.

• Do not install unit at a site with oil splashing or steam in much quantity.

• Do not install unit at a site where combustible gas may generate, flow in, stagnate or leak.

• Do not install unit at a site where equipment generating high frequency waves (a high frequency wave welder for example) is provided.

• Do not install unit at a site where fire detector is located at the supply air side. (Fire detector may operate erroneously due to the heated air supplied during heating operation.)

• When special chemical product may scatter around such as site chemical plants and hospitals, full investigation is required before installing unit. (The plastic components may be damaged depending on the chemical product applied.)

• If the unit is run for long hours when the air above the ceiling is at high temperature/ high humidity (due point above 26

°

C), due condensation may be produced in the indoor unit. When operating the units in this condition, add insulation material (10-

20 mm) to the entire surface of the indoor unit to avoid due condensation.

Cautions On Refrigerant Piping

Be sure to use non-oxidative brazing for brazing to ensure that no foreign matter or moisture enter into the pipe.

Be sure to apply refrigerating machine oil over the flare connection seating surface and tighten the connection using a double spanner.

s

Provide a metal brace to support the refrigerant pipe so that no load is imparted to the indoor unit end pipe. This metal brace should be provided

50 cm away from the indoor unit’s flare connection.

6.4. Purging procedures leak test

PURGING PROCEDURES

Connect the refrigerant pipes (both the liquid and gas pipes) between the indoor and the outdoor units.

Remove the service port cap of the stop valve on the side of the outdoor unit gas pipe.

(The stop valve will not work in its initial state fresh out of the factory (totally closed with cap on).)

Connect the gage manifold valve and the vacuum pump to the service port of the stop valve on the gas pipe side of the outdoor unit.

Run the vacuum pump. (Vacuumize for more than 15 minutes.)

Check the vacuum with the gage manifold valve, then close the gage manifold valve, and stop the vacuum pump.

Leave it as is for one or two minutes. Make sure the pointer of the gage manifold valve remains in the same position. Confirm that the pressure gage show -0.101MPa

(-760 mmHg).

6.5. Drain piping work

• Ensure that the drain piping is downward (pitch of more than 1/100) to the outdoor

(discharge) side. Do not provide any trap or irregularity on the way. ( 1 )

• Ensure that any cross-wise drain piping is less than 20 m (excluding the difference of elevation). If the drain piping is long, provide metal braces to prevent it from waving. Never provide any air vent pipe. Otherwise drain may be ejected.

• Use a hard vinyl chloride pipe O.D. ø32 for drain piping.

• Ensure that collected pipes are 10 cm lower than the unit body’s drain port as shown in 2 .

• Do not provide any odor trap at the drain discharge port.

• Put the end of the drain piping in a position where no odor is generated.

• Do not put the end of the drain piping in any drain where ionic gases are generated.

• After connecting the drain piping, make sure that water is discharged properly and that there are no leaks.

9. Test run

9.1. Before test run

s

After completing installation and the wiring and piping of the indoor and outdoor units, check for refrigerant leakage, looseness in the power supply or control wiring, wrong polarity, and no disconnection of one phase in the supply.

s

Use a 500-volt megohmmeter to check that the resistance between the power supply terminals and ground is at least 1.0 M

Ω

.

s

Do not carry out this test on the control wiring (low voltage circuit) terminals.

Warning:

Do not use the air conditioner if the insulation resistance is less than 1.0 M

Ω

.

Insulation resistance

After installation or after the power source to the unit has been cut for an extended period, the insulation resistance will drop below 1 M

Ω

due to refrigerant accumulating in the compressor. This is not a malfunction. Perform the following procedures.

1. Remove the wires from the compressor and measure the insulation resistance of the compressor.

2. If the insulation resistance is below 1 M

Ω

, the compressor is faulty or the resistance dropped due the accumulation of refrigerant in the compressor.

3. After connecting the wires to the compressor, the compressor will start to warm up after power is supplied. After supplying power for the times indicated below, measure the insulation resistance again.

• The insulation resistance drops due to accumulation of refrigerant in the compressor. The resistance will rise above 1 M

Ω

after the compressor is warmed up for two to three hours.

(The time necessary to warm up the compressor varies according to atmospheric conditions and refrigerant accumulation.)

• To operate the compressor with refrigerant accumulated in the compressor, the compressor must be warmed up at least 12 hours to prevent breakdown.

4. If the insulation resistance rises above 1 M

Ω

, the compressor is not faulty.

Caution:

• The compressor will not operate unless the power supply phase connection is correct.

• Turn on the power at least 12 hours before starting operation.

- Starting operation immediately after turning on the main power switch can result in severe damage to internal parts. Keep the power switch turned on during the operational season.

Service port

1. Connect gas cylinder to the service port of stop valve (3-way).

2. Execute air purge of the pipe (or hose) coming from refrigerant gas cylinder.

3. Replenish specified amount of refrigerant, while running the air conditioner for cooling.

Note:

In case of adding refrigerant, comply with the quantity specified for the refrigerating cycle.

Caution:

• Do not discharge the refrigerant into the atmosphere.

Take care not to discharge refrigerant into the atmosphere during installation, reinstallation, or repairs to the refrigerant circuit.

• For additional charging, charge the refrigerant from liquid phase of the gas cylinder.

If the refrigerant is charged from the gas phase, composition change may occur in the refrigerant inside the cylinder and the outdoor unit. In this case, ability of the refrigerating cycle decreases or normal operation can be impossible. However, charging the liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly.

To maintain the high pressure of the gas cylinder, warm the gas cylinder with warm water (under 40
