Special Remarks

Heating ( ) Operation

Heating performance

Defrosting

POWER lamp

Because this air conditioner heats a room by drawing on the heat of the outside air
(heat pump system), the heating efficiency will fall off when the outdoor temperature
is very low. If sufficient heat cannot be obtained with this air conditioner, use another
heating appliance in conjunction with it.

When the outdoor temperature is low, frost or ice may from in the heat exchanger
coil, reducing heating performance. When this happens, a microcomputer defrosting
system will operate. At the same time the fan on the indoor unit stops ( or runs at
very low speed in some cases). Heating operation restarts after several minutes.
(This interval will vary slightly depending upon the outdoor temperature and the way
in which frost forms).

For several minutes after the start of heating operation, the indoor fan will not start
running until the indoor heat exchanger coil has warmed up sufficiently. This is
because the COLD DRAFT PREVENTION SYSTEM is operating.

The POWER lamp also remains lit during defrosting or when the compressor has
been turned off by the thermostat when the system is in the heating mode.

Power failure
during operation

Clicking Sound

Clicking sound is

heard from the air

conditioner

In the event of power failure, the unit will stop. When the power is resumed,
the unit will restart automatically after three minutes.

In heating or cooling operation. Some plastic parts may expand of shrink due to a
sudden temperature change. In this event, a clicking sound may occur. This is normal,
and the sound will soon disappear.

The remote control unit sends the temperature signal to the air conditioner regularly
at three-minute intervals. If the signal from the remote control unit stops for more
than ten minutes due to the loss of the remote control unit or other trouble, the air
conditioner will switch to the temperature sensor which is built into the indoor unit
and control the room temperature. In these cases, the temperature around the
remote control unit may differ from the temperature detected at the air conditioner s

position.

5.Air purging

Air and moisture remaining in the refrigerant system have
undesirable effects as indicated below. Therefore, they must be
purged completely.

pressure in the system rises
operating current rises
cooling efficiency drops
moisture in the air may freeze and block capillary tubing
water may lead to corrosion of parts in the refrigerant system

Air Purging with a Vacuum Pump (for Test Run)

(1)Check that each tube (both narrow and wide tubes between

the indoor and outdoor units have been properly connected
and all wiring for the test run has been completed. Note that
both narrow and wide tube service valves on the outdoor
unit are kept closed at this stage.

(2)Using an adjustable wrench or box wrench, remove the valve

caps from the service valve on both narrow and wide tubes.

(3) Connect a vacuum pump and a manifold valve (with

pressure gauges) to the service port on the wide tube
service valve.(Fig.A)

Be sure to use a manifold valve for air
purging. If it is not available, use a
stop valve for this purpose. The ¡°Hi¡±
knob of the manifold valve must

CAUTION

always be kept closed.

(4)With the ¡°Lo¡±knob of the manifold valve open, run the vacuum

pump. The operation time for the vacuum pump varies with
tubing length and the capacity of the pump. The following table
shows the amount of time for evacuation:

of 100 liter/h vacuum pump is used

If tubing length is less than 10 m

10 min. or more

If tubing length is more than 10 m

15 min. or more

NOTENOTE

The required time in the above table is calculated based
on the assumption that the ideal (or target) vacuum
condition is around 10 mmHg abs.

(5) With the vacuum pump still running, close the Lo

knob of the manifold valve. Then stop the vacuum
pump.

(6)With the accessory hex wrench, turn the valve stem on

the narrow tube service valve counterclockwise by 90
degrees (1/4 turn) for 10 seconds, and then turn the
stem clockwise to close it again. (Fig.B)

Be sure to completely insert the hex
wrench before attempting to turn the
valve.

CAUTION

Fig.B

(7)Leak test all joints at the tubing (both indoor and outdoors)
with liquid soap. Bubbles indicate a leak. Be sure to wipe off
the soap with a clean cloth.
(8)With the hex wrench, turn the wide tube service valve stem

counter-clockwise to fully open the valve.

(9)Turn the narrow tube service valve stem counter-clockwise

to fully open the valve.

(10)Loosen the vacuum hose connected to the wide tube

service port slightly to release the pressure. Then, remove
the hose.

(11)Replace the bonnet and flare nut on the wide tube service

port and fasten the flare nut securely with an adjustable
wrench or box wrench. Next, mount the valve cap and
tighten it with a torque wrench (the cap needs to be
tightened with the torque of 200kg-cm). This process is

very important to prevent gas from leaking from the system.
(12)Test run the air conditioner.
(13)While the air conditioner is running, apply liquid soap to

check for any gas leaks around the service valves or caps.
(14)If there is no leakage, stop the air conditioner.
(15)Wipe off the soap on the tubing.
This completes air purging with a vacuum pump and
the air conditioner is ready for actual operation.
