1. Precautions
1) Turn off the the power.
Be sure to turn off the power before attempting to repair the unit such as the disassembly of the unit.
2) Be careful of electric shock
When checking the circuit with the power connected in unavoidable circumstances, take special care not to touch the live parts. There is a danger of electric shock.
3) Use of appropriate parts
Be sure to use the genuine parts of the relevant model when it is necessary to replace parts. (Replace parts instead of repairing with regard to the malfunctioning of electric contact areas.
Never attempt to modify the unit. It is extremely dangerous for the consumer to attempt to repair the unit on his(her) own.)
4) Use of proper tools
Use appropriate tools for repair, and use measuring equipment after accurate calibration. Using worn tools may result in problems, including poor contact and poor connection.
5) Avoid damage to electric wire or electric cord.
Check the electric cord or electric wire for any damage during repair.
Be sure to replace it if damaged.
6) Avoid intermediate connection of the electric cord.
Never attempt to make an intermediate connection by cutting the middle area of the electric cord or make a connection to the power receptacle as it is very dangerous, causing problems or fire.
7) Checking of insulation
Be sure to check the insulation resistance after completion of the assembly work.
(Check whether the insulation resistance of the electric wire and grounding terminal is over 30M
Ω
by using the insulation resistance tester, and then connect the power source.)
8) Checking of grounding
Check the grounding condition, and perform repair if poorly grounded.
9) Checking of installation condition
Check the installation condition of the unit, and perform repair if there is any defective area.
If the unit remains in an unstable installing condition, install it at a new site.
10) Be careful of children
As the repair of the unit involves a lot of dangerous elements, do not allow children to approach nearby during repair work.
Cleaning
Turn off the sub power switch separately installed.
No connection with the power receptacle
Upon completion of the repair, clean the air conditioner and surrounding area, and inform the customer of completion of the repair.

3-4-3 Installation Method
3-4-3(a) Installation Procedures
1 . Open the inlet grille, and remove the flare nut.
2. Bend the connection pipe to an appropriate length using the spring bender depending upon the installation place.
- Allowable pipe length : Maximum 25m
- Allowable pipe drop distance : Maximum 15m
- Make no more than ten bending points on the pipe
• When the pipe length is in excess of the standard pipe length of 5m, add the refrigerant
(R-22) of 50g for each additional 1m.
CAUTION
• If the pipe is lengthened, the performance of the unit is degraded, and the service life is shortened.
Therefore, the pipe length should be as short as possible (less then 15m).

3. Install the high pre s s u re pipe to the heat exchanger liquid pipe, and the low pre s s u re pipe to the heat exchanger gas pipe respectively using the flare nut, taking care not to cause any leakage of re f r i g e r a n t .
4. Be sure to insulate the pipe with appropriate insulation material.
5. Insert the drain hose into the drain pipe, and connect them by tying them to the cable tie to prevent any water leakage.
6. After completion of the installation, check the connecting area for any gas leakage.
7. Wind a finish tape when the wiring of the refrigerant pipe, the unit, and the drain piping are comp l e t e d .

Pipe Bending
1. Perform bending of the pipe using the bender which has a specified bending radius.
2. Be sure to take full care to perform bending of the pipe successfully at one time.
Bending and unbending the pipe more than twice makes the bending work increasingly diff i c u l t .
3. You may use the spring inserted into the gas pipe instead of the bender to bend the pipe.
4. When you bend the pipe using the spring, hold the pipe with both hands to prevent any distortion, and secure a minimum bending radius of more than 100mm.

When the trouble is not related to the 1st or 2nd items above, check the troubled area in detail in accordance with the fault analysis method by symptom.
5-1 Items to be checked first
1 ) Is the supply voltage appro p r i a t e ?
The supply voltage: should be AC 187V-AC 253V/60Hz
2) Is the connecting wire between the indoor unit and outdoor unit appro p r i a t e ?
Be sure to check whether the cables for the indoor unit and outdoor unit are securely connected by the same terminal number.

No.
Operation of air-conditioner Description
1 The compressor does not operate even though the desired temperature is set lower than
The compressor operation is delayed for 3 minutes for the protection of it during the restart of compressor. It operates normally after 3 minutes room temperature (during the cooling operation) delay even at the initial operation.
2 The hot wind does not come out even though the In order to prevent the discharging of cool wind, the room fan motor desired temperature is set higher than the room operates only when the temperature of indoor heat exchanger is kept temperature. (heating operation) higher than a constant one.
3 The wind quantity is not controlled during the automatic (cooling/heating) turbo operation.
The wind quantity is set by the micom during the automatic turbo operation.
4 The temperature can not be set during the automatic (cooling/heating) turbo blowing operation.
The desired temperature is set automatically during the automatic turbo operation. The wind blowing operation is simply the operation mode for the circulation of indoor air.
