Special Remarks
Heating (
) Operation
Heating performance
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).
Defrosting
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.
POWER lamp
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.
In the event of power failure, the unit will stop. When the power is resumed,
the unit will restart automatically after three minutes.
Power failure
during operation
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.
Clicking Sound
Clicking sound is
heard from the air
conditioner
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
position.

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.
Vacuum pump
(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
knob of the manifold valve must
always be kept closed.

CAUTION
Vacuum hose to manifold valve
(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:
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.
Table
Required time for evacuation when capacity
of 100 liter/h vacuum pump is used
If tubing length is more than 10 m
15 min. or more
If tubing length is less than 10 m
10 min. or more
(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.
NOTE
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)
This completes air purging with a vacuum pump and
the air conditioner is ready for actual operation.
6. Please contact the technical service for further
information.
Be sure to completely insert the hex
wrench before attempting to turn the
valve.
