■Fixing and Piping

• Piping must be performed by qualified personnel

according to good refrigeration systems practices.

• Piping materials and insulation materials must be of

refrigerant quality.

• Select the pipe diameters according to the size of unit

and cut the pipe to design length by using pipe cutter.

• Install the flare nuts and flare the end of the pipes.

• Check that no foreign bodies are inside the piping.

• Align the central of the connecting pipes and tighten

the flare nut.

• Fix piping with pipe clamps and check that any pipe

vibrations cannot be transmitted to the building

structure.

• Connect the pipe correctly.

• Do not apply the excessive torque.

• Use an appropriate bending tool to form curves and

avoid over-tightening the refrigerant tubes.

• To prevent heat loss, the two lines must be insulated

separately.

■ Maximum Piping Length

The suction line must have a 2% gradient up to the

compressor on horizontal sections.

Where piping lengths are unusually long and include a

large number of oil traps, it may be necessary to adjust

to compressor charge.

■Refrigerant piping connections

(FLARE connections)

To avoid alteration of unit capacities, check that piping lengths

and changes in elevation are kept to a strict minimum.

Before connectiong the refrigerant lines, follow the

procedures below (if pre-charged connection lines are

not supplied):

- Select copper pipe diameters according to the size of

unit to be installed.

- Install the refrigeration lines, checking that no foreign

boodies get inside the piping.

- Install the flare connectors and flare the ends of the pipes.

- Evacuate the piping. This operation, which should last

at least 15 minutes if there are large piping lengths and

changes in elevation, should be followed by a leak test.

Refrigerant charge to be added per extra meter

of piping length when more than 7.5 meters.

OPERATION TIPS

The following events may occur during normal operation.

1. Protection of the air conditioner.

Compressor protection

•The compressor can’t restart for 3 minutes after it stops.

Anti-cold air (Cooling and heating models only)

•The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the following

three situations and the set temperature has not been reached.

A) When heating has just starting.

B) Defrosting.

C) Low temperature heating.

•The indoor or outdoor fan stop running when defrosting (Cooling and heating models only).

Defrosting (Cooling and heating models only)

•Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is

high resulting in lower heating efficiency of the air conditioner.

•During this condition air conditioner will stop heating operation and start defrosting automatically.

•The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of frost

buildup on the outdoor unit.

2. A white mist coming out from the indoor unit.

•A white mist may generate due to a large temperature difference between air inlet and air outlet on COOL mode

in an indoor environment that has a high relative humidity.

•A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts in

HEAT mode operation after defrosting.

3. Low noise of the air conditioner.

•You may hear a low hissing sound when the compressor is running or has just stopped running.

This sound is the sound of the refrigerant flowing or coming to a stop.

•You can also hear a low “squeak” sound when the compressor is running or has just stopped running. This is

caused by heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing.

•A noise may be heard due to louver restoring to its original position when power is first turned on.

4. Dust in blown out from the indoor unit.

This is a normal condition when the air conditioner has not been used for a long time or during first use of the unit.

5. A peculiar smell come out from the indoor unit.

This is caused by the indoor unit giving off smells permeated from building material, from furniture, or smoke.

6. The air conditioner turns to FAN only mode from COOL or HEAT (for cooling and heating models only) mode.

When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop automatically,

and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on

COOL mode or falls on HEAT mode (for cooling and heating models only) to the set point.

7. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity (relative

humidity higher than 80%). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.

8. Heating mode (For cooling and heating models only)

The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating operation.

When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time,

heat loading of the air conditioner increases due to larger difference between indoor and outdoor temperature. If a

comfortable temperature can’t be achieved by the air conditioner, we suggest you use a supplementary heating device.

9. Auto-restart function

Power failure during operation will stop the unit completely.

For the unit without Auto-restart feature, when the power restores, the OPERATION indicator on the indoor unit starts

flashing. To restart the operation, push the ON/OFF button on the remote controller. For the unit with Auto-restart

feature, when the power restores, the unit restarts automatically with all the previous settings preserved by the memory

function.

10.

Lightning or a car wireless telephone operating nearby may cause the unit to malfunction.

Disconnect the unit with power and then re-connect the unit with power again. Push the ON/OFF button on the remote

controller to restart operation.
