• Turn off the power supply when the filter is changed.

3. How to operate

In case of failure

Warning:

• Never remodel the unit. Consult your dealer for any repair service. Improper repair work can result in water leakage, electric shock, fire, etc.

• If the remote controller displays an error indication, the unit does not run, or there is any abnormality, stop operation and contact your dealer.

Leaving the unit as it is under such conditions can result in fire or failure.

• If the power breaker is frequently activated, get in touch with your dealer.

Leaving it as it is can result in fire or failure.

• If the refrigeration gas blows out or leaks, stop the operation of the unit, thoroughly ventilate the room, and contact your dealer. Leaving the unit as it is can result in accidents due to oxygen deficiency.

When the unit is not to be used for a long time

• If the unit is not to be used for a long time due to a seasonal change, etc., run it for 4 - 5 hours with the air blowing until the inside is completely dry.

Failing to do so can result in the growth of unhygienic, unhealthy mold in scattered areas throughout the room.

• When it is not to be used for an extended time, keep the [power supply] turned OFF.

If the power supply is kept on, several watts or several tens of watts will be wasted. Also, the accumulation of dust, etc., can result in fire.

• Keep the power switched ON for more than 12 hours before starting operation. Do not turn the power supply OFF during seasons of heavy use.

Doing so can result in failure.

1.3. Disposing of the unit

6. The smart way to use

Even minimal steps to care for your unit can help make its use far more effective in terms of air-conditioning effect, electricity charges, etc.

Clean the filter thoroughly

• If the screen of the air filter becomes clogged, the airflow and air-conditioning effect can be significantly reduced.

Further, if the condition is left unattended, failure can result. It is particularly important to clean the filter at the beginning of the cooling and heating seasons. (When profuse dust and dirt have accumulated, clean the filter thoroughly.)

Prevent intrusion of heat during air-cooling

• To prevent the intrusion of heat during cooling operation, provide a curtain or a blind on the window to block out direct sunlight. Also, do not open the entrance or exit except in cases of dire necessity.

Carry out ventilation sometimes

• Since the air periodically gets dirty in a room that is kept closed for a long time, ventilation is sometimes necessary. When gas appliances are used together with the unit, special precautions must be taken. If the “LOSSNAY” ventilation unit developed by our company is used, you can perform ventilation with less waste. For details on this unit, consult with your dealer.

7. Caring for the unit

Always have filter maintenance performed by a service person.

Before care-taking, turn the power supply OFF.

Caution:

• Before you start cleaning, stop operation and turn OFF the power supply.

Remember that the fan is rotating inside at high speed, posing a serious risk of injury.

• Indoor units are equipped with filters to remove the dust of sucked-in air.

Clean the filters using the methods shown in the following sketches. (The standard filter should normally be cleaned once a week, and the long-life filter at the beginning of each season.)

• The life of the filter depends on where the unit is installed and how it is operated.

How to clean

• Clear dust away lightly or clean it up with a vacuum cleaner. In the case of severe staining, wash the filter in lukewarm water mixed with dissolved neutral detergent or water, and then rinse off the detergent completely. After washing, dry it and fix it back into place.

Caution:

• Do not dry the filter by exposing it to direct sunlight or warming it using fire, etc. Doing so can result in the deformation of the filter.

• Washing it in hot water (more than 50

°

C) can also result in deformation.

Caution:

Never pour water or flammable sprays onto the unit. Cleaning using these methods can result in the failure of the unit, electric shock, or fire.

8. Troubleshooting

Before you ask for repair service, check the following points:

State of Machine

There are some obstacles at the air inlet and outlet of the indoor and outdoor units.

The filter is filled with dust and dirt.

Troubleshooting

Press the [ON/OFF] button after power restoration.

Turn the power supply ON.

Replace fuse.

Put in the earth leakage breaker.

After checking the set temperature and inlet temperature on the liquid crystal display, refer to [Room temperature adjustment], and operate the adjustment button.

Clean up the filter.

(Refer to [Caring for the machine].)

Remove.

Close.

Wait for a while.

(To protect the compressor, a 20-seconds restart-preventing circuit is built into the indoor unit. Therefore, there are occasions sometimes when the compressor does not start running immediately. There are cases when it does not run for as long as 20-seconds.)

Rerun after removal

Rerun after cleaning the filter. (Refer to [Caring for the machine].)

• If operation stops due to a power failure, the [restart-preventing circuit at power failure] operates and disables unit operation even after power restoration. In this case, press the [ON/OFF] button again and start operation.

If malfunctions persist after you have checked the above, turn the power supply OFF and contact your dealer with information about the product name, the nature of the malfunction, etc. If the display of “[check]” and (4 digit) check code flashes, tell the dealer contents of the display (check code). Never attempt to repair by yourself.

The following symptoms are not unit failures:

• The air blown out from the unit can sometimes give off odors. This is due to cigarette smoke contained in the air of the room, the smell of cosmetics, the walls, furniture, etc., absorbed in the unit.

• A hissing noise can be heard immediately after the unit is started or stopped. This is the sound of the refrigeration flowing inside the unit. This is normal.

• The unit sometimes snaps or clicks at the beginning or end of cooling/heating operation. This is the sound of friction on the front panel and other sections due to expansion and contraction caused by temperature change. This is normal.

• A white mist of steam may be emitted from the indoor unit when operation commences at high indoor temperature or humidity.

9. Installation, transferring works, and checking

Regarding place for installation

Consult with your dealer for details on installation and transferring the installation.

Caution:

Never install the unit where there is a risk of leakage of flammable gas.

If gas leaks and accumulates around the unit, fire can result.

Never install the unit at the following place:

• where there is a lot of machine oil

• near the ocean and beach areas where there is salt air.

• where humidity is high

• where there are hot springs nearby

• where there is sulphurous gas

• where there is a high-frequency processing machinery (a high-frequency welder, etc.)

• where acid solution is frequently used

• where special sprays are frequently used

• Install the indoor unit horizontally. Otherwise, water leakage can result.

10

• Take sufficient measures against noise when installing the units at hospitals or communication-related businesses.

If the unit is used in any of the above-mentioned environments, frequent operational failure can be expected. It is advisable to avoid these types of installation sites.

For further details, consult with your dealer.

Regarding electrical work

Caution:

• The electrical work must be undertaken by a person who is qualified as an electrical engineer according to the [technical standard respecting electrical installation], [internal wiring rules], and the installation instruction manual with the absolute use of exclusive circuits. The use of other products with the power source can result in burnt-out beakers and fuses.

• Never connect the grounding wire to a gas pipe, water pipe, arrester, or telephone grounding wire. For details, consult with your dealer.

• In some types of installation sites, the installation of an earth leakage breaker is mandatory. For details, consult with your dealer.

Regarding transfer of installation

• When removing and reinstalling the unit when you enlarge your home, remodel, or move, consult with your dealer in advance to ascertain the cost of the professional engineering work required for transferring the installation.

Caution:

When moving or reinstalling the unit, consult with your dealer. Defective installation can result in electric shock, fire, etc.

Regarding noise

• In installing work, choose a place that can fully bear the weight of the unit, and where noise and vibration can be reduced.

• Choose a place where cool or warm air and noise from the outdoor air outlet of the unit does not inconvenience the neighbors.

• If any alien object is placed near the outdoor air outlet of the unit, decreased performance and increased noise can result. Avoid placing any obstacles adjacent to the air outlet.

• If the unit produces any abnormal sound, consult with your dealer.

Maintenance and inspection

• If the unit is used throughout several seasons, the insides can get dirty, reducing the performance.

Depending upon the conditions of usage, foul odors can be generated and drainage can deteriorate due to dust and dirt, etc.

10. Checking Drainage

Check that water is able to drain smoothly. If water is unable to drain smoothly, check for blockage of the grooves in the drain pan and the piping trap by paper particles etc.

Carefully clean the grooves in the drain pan and the piping trap to prevent further blockage.

Ensure that the trap is always water-sealed.

11. Checking V Belts

1. Adjust parallel of the fan and motor pulleys in accordance with Fig.B-1.

2. Adjust the tension of each V belt so that the deflection load (W) at the optimum deflection ( r= 5 mm) is as shown in Fig.B-2.

3. It is recommended that the belt be adjusted to the optimum tension as shown in Fig.B-2 after it has been run-in on the pulley (24 - 28 hours operation). When a new belt is fitted, adjust the deflection load (W) to approximately 1.3 times the maximum value.

4. It is recommended that the V belt be replaced every 8000 hours. It has reached the end of its life when it has stretched by approximately 2% (including an initial stretch of approximately 1%) of the initial circumference.
