Deciding on Where to Install the Outdoor Unit
Outdoor Unit
◆ The outdoor unit must NEVER be placed on its side or upside down, as the
compressor lubrication oil will run into the cooling circuit and seriously
damage the unit.
◆ Choose a location that is dry and sunny, but not exposed to direct sunlight or
strong winds.
◆ Do not block any passageways or thoroughfares.
◆ Choose a location where the noise of the air conditioner when running and
the discharged air do not disturb any neighbours.
◆ Choose a position that enables the pipes and cables to be easily connected
to the indoor unit.
◆ Install the outdoor unit on a flat, stable surface that can support its weight
and does not generate any unnecessary noise and vibration.
◆ Position the outdoor unit so that the air flow is directed towards the open
area.
◆ Maintain sufficient clearance around the outdoor unit, especially from a radio,
computer, stereo system, etc.

Performing Leak Test & Vacuum Drying
Before completing the installation(insulation of the hose and piping),
you must check that there are no gas leaks and remove air in the unit.
1
Purge the refrigerant pipes and perform the vacuum test.
Note
◆ The pressure should not be increased for 1 minute.
2
Inject nitrogen into the pipes until the pressure becomes 2kg/cm2 at least.
3
Check for gas leaks by using soapy water.
4
Let the pipes under 28kg/cm2 pressure for 24 hours, then check that the
pressure has been decreased.
5
Discharge the nitrogen.
6
Make the pipes vacuous.
7
If the piping is longer than the standard length, refrigerant must be added.
For further details on adding refrigerant, refer to page 20.

ENGLISH
Insulation
Once you have checked that there are no leaks in the system, you can
insulate the piping and hose.
1
To avoid condensation problems, place an insulator around each
refrigerant pipe.
Note
No gap
◆ When insulate the pipe, be sure to overlap the insulation.
◆ You have to use more than 120°C insulation(T13.0 or thicker
Acrylonitrile Butadien Rubber) for the gas refrigerant pipe.
NBR(T13.0 or thicker)
2
If you have not insulated the refnet joint, you should insulate it.
For the refnet joint insulation, refer to page 16.
E-19
Adding Refrigerant
The outdoor unit is loaded with sufficient refrigerant for the standard
piping. Thus, refrigerant must be added if the piping is lengthened.
This operation can only be performed by a qualified refrigeration
specialist. For quantity of adding refrigerant, refer to page 21.
1
Check that the stop valve is closed entirely.
2
Charge the refrigerant through the service port of liquid stop valve.
Note

Checking and Testing Operations
To complete the installation, perform the following checks and tests to
ensure that the air conditioner is operating correctly.
Review all the following elements in the installation :
◆ Piping connection tightness to detect any gas leakages
◆ Connecting wiring
◆ Heat-resistant insulation of the piping
◆ Drainage
◆ Earthing wire connection
◆ Correct operations (follow the steps below)
How to Test Operations
1
Check the power supply.
◆ Compressor power supply : L1(R)-Red, L2(S)-White, L3(T)-Black
Be careful about the cables so that they will not be mixed up.
◆ 220-240V power supply : L, N (Single phase cable)
2
Check the indoor unit(s).
2-1 Check that you have connected the power and communication
cables correctly. (Communication cables should be connected with
F1 and F2 terminals)
- If the power cables and communication cables are mixed up or
connected incorrectly, the PCB will be damaged.
2-2 Ensure the address of indoor units.
- Choose appropriate address between 0 and F.
- Each indoor unit must have different address.
2-3 Check the thermistor sensor, drain pump/hose, and electronic
expansion valve are connected correctly.
3
Check the outdoor unit(s).
3-1 Check how many indoor units are installed and the number of
indoor units registered on the rotary switch.
3-2 Check the DIP switch is at proper position.
E-28
4
Connect the outdoor unit to your computer where the provided software is
installed, then power the outdoor unit on.
5
If the outdoor unit is powered on, it will start tracking to check user's
option(s) and number of indoor unit. It takes about 20 seconds.
- At this time, the SEG 1 and 2 on outdoor unit PCB display the number of
indoor unit registered and the SEG 3 and 4 display the number of
indoor units which responded.
ENGLISH
6
If both sides numbers are equal, your computer will perform the next
stage.
Note
◆ If 'E2' is displayed on the outdoor unit PCB at this time, you
must check that you registered the number of indoor units
and assigned addresses correctly. Then restart the tracking
by pressing the key 3 in the outdoor unit.
7
Check the thermistor sensor, electronic expansion valve by using the
computer.
8
Open the service valve, then press the test operation KEY on the outdoor
unit PCB.
9
Check the pressure switch by a manifold gauge.
- Refer to the pressure table classified by outdoor temperature and
length of piping.
- The pressure is variable at the beginning of compressor operation.
Thus, check the pressure valve after 20 minutes at least.
- If there is an unusual noise and no change of pressure, you have to
check the compressor power(L1, L2 and L3) and wire connection.
10 Check these elements by using the computer.
10-1 Check each indoor unit temperature, RPM, capacity code,
and open degree of electronic expansion valve.
10-2 Check the temperature of compressor and condenser,
and outdoor unit fan operation.
11 Check that there is any error mode in the outdoor unit PCB during the test.
- You should test operations for 2 hours or more.
- Check that the water dripping from the drain hose runs away correctly
and safely.
12 To finish the test, press the test operation KEY again.
13 After finishing the test, operate only one indoor unit in the cool mode for
30 minutes.
- Check the temperature of the other indoor units and leakage of electronic
expansion valve. If there is no matter, turn the indoor unit off, then
operate another indoor unit to check the previous indoor unit.
