TIPS FOR SAVING ENERGY
Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
• Do not cool excessively indoors. This may be harmful to your health and may consume more electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

LEAKAGE TEST AND EVACUATION 19
ENGLISH
LEAKAGE TEST AND EVACUATION
Air and moisture remaining in the refrigerant
system have undesirable effects as indicated
below.
- Pressure in the system rises.
- Operating current rises.
- Cooling(or heating) efficiency drops.
- Moisture in the refrigerant circuit may freeze
and block capillary tubing.
- Water may lead to corrosion of parts in the
refrigeration system.
Therefore, the indoor/outdoor unit and connecting tube must be checked for leak tight,
and vacuumed to remove incondensible gas
and moisture in the system.
Preparation
Check that each tube(both liquid and gas side
tubes) between the indoor and outdoor units
have been properly connected and all wiring
for the test run has been completed. Remove
the service valve caps from both the gas and
the liquid side on the outdoor unit. Check that
both the liquid and the gas side service valves
on the outdoor unit are kept closed at this
stage.
! CAUTION
To avoid nitrogen entering the refrigerant
system in a liquid state, the top of the
cylinder must be higher than its bottom
when you pressurize the system. Usually,
the cylinder is used in a vertical standing
position.
- Do a leakage test of all joints of the
tubing(both indoor and outdoor) and both gas
and liquid side service valves.
Bubbles indicate a leak. Be sure to wipe off
the soap with a clean cloth.
- After the system is found to be free of leaks,
relieve the nitrogen pressure by loosening
the charge hose connector at the nitrogen
cylinder. When the system pressure is
reduced to normal, disconnect the hose from
the cylinder.
Indoor unit
Outdoor unit
Leakage test
Connect the manifold valve(with pressure
gauges) and dry nitrogen gas cylinder to this
service port with charge hoses.
Manifold valve
! CAUTION
Be sure to use a manifold valve for leakage
test. If it is not available, use a stop valve for
this purpose. The "Hi" knob of the manifold
valve must always be kept close.
- Pressurize the system to no more than
3.8 Mpa with dry nitrogen gas and close
the cylinder valve when the gauge reading reached 3.8 MPa Next, test for leaks
with liquid soap.

Evacuation
- Connect the charge hose end described in
the preceding steps to the vacuum pump to
evacuate the tubing and indoor unit.
Confirm the "Lo and Hi" knob of the manifold
valve is open. Then, run the vacuum pump.
The operation time for evacuation varies with
tubing length and capacity of the pump. The
following table shows the time required for
evacuation.
- Replace the valve caps at both gas and liquid
side service valves and fasten them tight.
This completes air purging with a vacuum pump.
The air conditioner is now ready to test run.

- With a service valve wrench, turn the valve
stem of liquid side valve counter-clockwise to
fully open the valve.
- Turn the valve stem of gas side valve counterclockwise to fully open the valve.
- Loosen the charge hose connected to the gas
side service port slightly to release the pressure,
then remove the hose.
- Replace the flare nut and its bonnet on the gas
side service port and fasten the flare nut securely with an adjustable wrench. This process is
very important to prevent leakage from the system.

TEST RUNNING 21
ENGLISH
TEST RUNNING
Precautions In Test Running
- The initial power supply must provide at least 90 % of the rated voltage.
Otherwise, the air conditioner should not be operated.
! CAUTION
For test run, carry out the cooling operation firstly even during heating season. If heating operation
is carried out firstly, it leads to the trouble of compressor. Then attention must be paid.
Carry out the test run more than 5 minutes without fail.
(Test run will be cancelled 18 minutes later automatically)
- The test run is started by pressing the room temperature checking button and down timer button for 3 seconds at the same time.
- To cancel the test run, press any button.
CHECK THE FOLLOWING ITEMS WHEN INSTALLATION IS COMPLETE
- After completing work, be sure to measure and record trial run properties, and store measured
data, etc.
- Measuring items are room temperature, outside temperature, suction temperature, blow out
temperature, wind velocity, wind volume, voltage, current, presence of abnormal vibration and
noise, operating pressure, piping temperature, compressive pressure.
- As to the structure and appearance, check following items.
□Is the circulation of air adequate?
□Is the draining smooth?
□Is the heat insulation complete
(refrigerant and drain piping)?
□Is there any leakage of refrigerant?
□Is the remote controller switch operated?
□Is there any faulty wiring?
□Are not terminal screws loosened?

M5......196 N·cm {20 kgf·cm}
M6......245 N·cm {25 kgf·cm}
M8......588 N·cm {60 kgf·cm}
Connection of power supply
• Connect the power supply cable to the independent power supply.
- Circuit breaker is required.
• Operate the unit for fifteen minutes or more.
Evaluation of the performance
- Measure the temperature of the intake and
discharge air.
- Ensure the difference between the intake
temperature and the discharge one is more
than 8 °C (Cooling) or reversely (Heating).

22 TEST RUNNING
ENGLISH
! CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1 Never fail to have an individual power specialized for the air conditioner. As for the
method of wiring, be guided by the circuit diagram pasted on the inside of control box
cover.
2 Provide a circuit breaker switch between power source and the unit.
3 The screw which fasten the wiring in the casing of electrical fittings are liable to come
loose from vibrations to which the unit is subjected during the course of transportation.
Check them and make sure that they are all tightly fastened. (If they are loose, it could
give rise to burn-out of the wires.)
4 Specification of power source
5 Confirm that electrical capacity is sufficient.
6 Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate.
7 Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8 Never fail to equip a leakage breaker where it is wet or moist.
9 The following troubles would be caused by voltage drop-down.
- Vibration of a magnetic switch, damage on the contact point there of fuse breaking, disturbance to the normal function of a overload protection device.
- Proper starting power is not given to the compressor.
