Whilst there is a correlation between the
emission and exposure levels, this cannot be
used reliably to determine whether or not
further precautions are required.
Factor that influence the actual level of
exposure of the workforce include the
characteristics of the work room and the other
sources of noise, i.e. the number of
equipment and other adjacent processes and
the length of time for which an operator
exposed to the noise. Also, the permissible
exposure level can vary from country to
country.
This information, however, will enable the
user of the equipment to make a better
evaluation of the hazard and risk.

28 LEAKAGE TEST AND EVACUATION
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 have 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.
Leakage test
- Connect the manifold valve (with pressure gauges) and dry nitrogen gas cylinder to this service
port with charge hoses.
!
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 using bubble test solution.
!
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.
LEAKAGE TEST AND EVACUATION 29
(both Indoor unit and outdoor unit) and
both gas and liquid side service valves.
Bubbles indicate a leak. Be sure to wipe
off the soap with a clean cloth.
2 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.

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.
- When the desired vacuum is reached, close
the "Lo and Hi" knob of the manifold valve
and stop the vacuum pump.
Finishing the job
- 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
counter-clockwise 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.
- 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.

TEST RUNNING
1 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?

TEST RUNNING 31
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.
10 Use only 1 remote-controller contained in indoor unit, when using simultaneous

INSTALLATION GUIDE
AT THE SEASIDE
!
CAUTION
• Air conditioners should not be installed
in areas where corrosive gases, such as
acid or alkaline gas, are produced.
• Do not install the product where it could
be exposed to sea wind (salty wind)
directly. It can result corrosion on the
product. Corrosion, particularly on the
condenser and evaporator fins, could
cause product malfunction or inefficient
performance.
• If outdoor unit is installed close to the
seaside, it should avoid direct exposure
to the sea wind. Otherwise it needs
additional anticorrosion treatment on the
heat exchanger.
Selecting the location (Outdoor Unit)
In case, to install the outdoor unit on the
seaside, set If the outdoor unit is to be
installed close to the seaside, direct exposure
to the sea wind should be avoided.
Install the outdoor unit on the opposite side of
the sea wind direction. a windbreak not to be
exposed to the sea wind.
Sea wind
Sea wind
In case, to install the outdoor unit on the
seaside, set up a windbreak not to be
exposed to the sea wind
Windbreak
Sea wind
- It should be strong enough like concrete to
prevent the sea wind from the sea.
- The height and width should be more than
150 % of the outdoor unit.
- More than 70 cm of space should be kept
between outdoor unit and the windbreak for
easy air flow.
Place with fluent water draining
- Install at a place with fluent water draining to
prevent damage from localized heavy rain
and avoid frequent flooded area.
• Periodic ( more than once/year )
cleaning of the dust or salt particles
stuck on the heat exchanger by using
water.
SEASONAL WIND AND CAUTIONS IN WINTER 41
- Sufficient measures are required in a snow
area or severe cold area in winter so that
product can operate well.
- Get ready for seasonal wind or snow in
winter even in other areas.
- Install a suction and discharge duct not to let
in snow or rain.
- Install the outdoor unit not to come in
contact with snow directly. If snow piles up
and freezes on the air suction hole, the
system may malfunction. If it is installed at
snowy area, attach the hood to the system.
- Install the outdoor unit at the higher
installation console by 50 cm than the
average snowfall (annual average snowfall) if
it is installed at the area with much snowfall.
- Where snow accumulated on the upper part
of the Outdoor Unit by more than 10 cm,
always remove snow for operation.
