English

From 4th July 2007 and following Regulation EC Nº 842/2006 on Certain Fluorinated Greenhouse gases, it is mandatory to ll in the label attached to the unit

with the total amount of refrigerant charged on the installation.

Do not vent R410A/R407C into the atmosphere: R410A & R407C are uorinated greenhouse gases covered by the Kyoto protocol global warming potential

(GWP) R410A/R407C: = 1975/1652.5.

- Factory Charge,



- Additional Charge &



- Total Charge.

2.- Stick the Protection Plastic Film on the F-Gas Label (delivered in a plastic bag with the Manual). To see Figure nº 2.

works must be performed by qualied service person.

• Do not put any strange material (sticks, etc...) into the air inlet

and outlet. These units have high speed rotating fans and it is

dangerous that any object touches them.

• Refrigerant leakage can cause difculty with breathing due to

insufcient air.

C A U T I O N

This unit is designed for commercial and light industrial applica-

tion. If installed in house hold appliance, it could cause electro-

magnetic interference.

Start-up and Operation: Check to ensure that all the stop valves

are fully opened and no obstacle exists at the inlet/outlet sides

before start-up and during the operation.

Maintenance: Periodically check the high pressure side pres-

sure. If the pressure is higher than the maximum allowable pres-

sure, stop the system and clean the heat exchanger or remove

the cause.

6 BEFORE OPERATION

C A U T I O N

• Supply electrical power to the system for approximately 12 hours

before start-up or a long shutdown. Do not start the system im-

mediately after power supply, it may cause a compressor failure

because the compressor is not heated well.

• When the system is started after a shutdown longer that ap-

proximately 3 months, it is recommended to check the system

by your service contractor.

• Turn OFF the main switch when the system is to be stopped

for a long period of time: If the main switch is not turned OFF,

electricity will be used, because the oil heater is always ener-

gised during compressor stopping.

• Make sure that the outdoor unit is not covered with snow or

ice. If covered, remove it by using hot water (approximately

50°C). If the water temperature is higher that 50 °C, it will

cause damage to plastic parts.

7 REMOTE CONTROLLER

It is advisable to use PC-ART or PC-ARF remote controller (both optional). For more information about it installation and operation,

please refer to its corresponding Installation and Operation Manuals.

5 TRANSPORTATION AND HANDLING

When hanging the unit, ensure a balance of the unit, check safety

and lift it up smoothly

Do not remove any packing materials.

Hang the unit under packing condition with two ropes.

For safety reasons ensure that the outdoor unit is lifted smoothly

and does not lean

8 AUTOMATIC CONTROLS

The system is equipped with the following functions.



Three minute guard

The compressor remains off for at least 3 minutes once it has

stopped. If the system is started within approximately 3 minutes

after it has stopped, the RUN indicator is activated. However, the

cooling operation or the heating operation remains off and does

not start until after 3 minutes has elapsed.

Operation may stop for 6 minutes maximum to protect compressor.



Frost prevention during cooling operation

When the system is operated in a low temperature room, the

cooling operation may be changed to fan operation for a while to

avoid frost formation on the indoor heat exchanger.



Automatic restart after power failure

If the power supply is interrupted for short periods of time (up to

2 seconds) the Remote Control switch will retain the settings and

the unit will restart when the power is restored. If Automatic Re-

start is required after periods of lost power supply in excess of 2

seconds please contact your distributor (optional function).



Slow air control during heating operation

Can be setting than when the compressor is stopped while the

thermostat is OFF, or the system is performing the automatic de-

frosting operation, the fan speed is set at the slow position.



Automatic defrosting cycle

When the heating operation is stopped by pressing RUN/STOP

switch, frosting on the outdoor unit is checked and the defrosting

operation may be performed for the maximum of 10 minutes.



Prevention of overload operation

When the outdoor temperature is too high during heating opera-

tion, heating operation is stopped due to activation of the outdoor

thermistor until the temperature becomes low.



Hot start during heating operation

To prevent cold air discharge, the fan speed is controlled from

the slow position to the set position according to the discharge air

temperature. At this time the lover is xed horizontally.

9 BASIC TROUBLESHOOTING

C A U T I O N

• When water leakage from the indoor unit occurs, stop the op-

eration and contact your contractor

• When you smell or white smoke occurs from the unit, stop the

system and contact your contractor.



This is not abnormal

• Sound from deforming Part

During system starting or stopping, and abrading sound might

be heard. However, this is due to thermal deformation of plastic

parts. It is not abnormal.

• Refrigerant Flow Sound

While the system is being started or stopping, sound from the

refrigerant ow may be heard.

• Smells from Indoor Unit

Smell adheres on indoor unit after a long period of time. Clean the

air lter and panels or make a good ventilation.

• Steam from Outdoor Heat Exchanger

During defrosting operation, ice on the outdoor heat exchanger is

melted, resulting in making steam.

• Dew on Air Panel

When the cooling operation continues for a long period of time

under high humidity conditions (higher than 27°C DB/80% R.H.),

dew can form on the air panel.

• Dew on Cabinet

When the cooling operation continues for a long period of timer

(higher than 27°C DB/80% R.H.), dew can form on the cabinet.

• Sound for the indoor unit heat exchanger

During the cooling operation, a sound may be heard from the in-

door unit heat exchanger due to water freezing or melting.



No operation

Check whether the SET TEMPERATURE is set at the correct

temperature.



Not cooling well or heating well

- Check for obstruction of air ow of the outside or inside

units.

- Check if too much heat source exists in the room.

- Check if the air lter is clogged with dust.

- Check to see if the doors or windows are opened or not.

- Check if the temperature condition is not within the operat-

ing range.



Abnormal swing louver’s position

Check if the four louver’s position at the air outlet are in same

position.



If trouble still remains...

If the trouble still remains even after checking the above items,

contact your service contractor and inform the following data:

- Unit Model Name

- Content of Trouble

- Alarm Code no. on Liquid Crystal Display

N O T E

Except for a long period of shutdown, keep the main switch ON,

since the oil heater is energised when the compressor is stopped.
