4-4. EXPLANATION TO THE USER
• Using the OPERATING INSTRUCTIONS, explain to the user how to use the air conditioner
WKHUHPRWHFRQWUROOHUUHPRYLQJWKHDLU¿OWHUVSODFLQJRUUHPRYLQJWKHUHPRWHFRQWUROOHU
from the remote controller holder, cleaning methods, precautions for operation, etc.)
• Recommend that the user read the OPERATING INSTRUCTIONS carefully.
Caution:
• After test run or remote signal reception check, turn off the unit with the E.O. SW or the
remote controller before turning off the power supply. If this procedure is not performed,
the unit will automatically begin operation when power supply is resumed.
To the user
• After installing the unit, explain to the user about auto restart function.
• If auto restart function is unnecessary, it can be deactivated. Consult the service
representative to deactivate the function. Refer to the service manual for details.
4-2. TEST RUN
1) Insert power supply plug into the power outlet and/or turn on
the breaker.
2) Press the E.O. SW once for COOL, and twice for HEAT (only
MSZ series) operation. Test run will be performed for 30
minutes. If the upper operation indicator light blinks every 0.5
seconds, inspect the indoor/outdoor unit connecting wire (A).
After the test run, emergency COOL mode (75°F [24°C] COOL)
will start.
3) To stop operation, press the E.O. SW several times until all
LED lamps turn off. Refer to operating instructions for details.
Checking the remote (infrared) signal reception
Press the OFF/ON button on the remote controller and listen for an audible indicator from
the indoor unit. Press the OFF/ON button again to turn the air conditioner off.
• Once the compressor stops, the restart preventive device operates so the compressor
will not operate for 3 minutes to protect the air conditioner.
4-3. AUTO RESTART FUNCTION
This product is equipped with an auto restart function. When the power supply is cut off during
operation, such as during blackouts, the function automatically starts operation in the previous
setting once the power supply is resumed. (Refer to the operating instructions for details.)

4-1. PURGING PROCEDURES AND LEAK TEST
1) Remove service port caps from stop valves on both sides of refrigerant lines. (The stop
valves are fully closed when shipped.) Leave closed.
2) Connect gauge manifold to ports of stop valves.

Precautions when using the control valve
When attaching the control valve
to the service port, valve core may
deform or loosen if excess pressure
is applied. This may cause gas leak.

4. PURGING PROCEDURES, LEAK TEST, AND TEST RUN
3) Evacuate the system to 4000 microns from both service valves. System manifold gauges
must not be used to measure vacuum. A micron gauge must be used at all times. Break
the vacuum with Nitrogen(N2) into the discharge service valve to 0 PSIG.
4) Evacuate the system to 1500 microns. Break the vacuum with Nitrogen(N2) into the
discharge service valve to 0 PSIG.
5) Evacuate the system to 500 microns.
6) Close gauge manifold valves, stop the pump, and conduct a 30 minute rise test.
7) System should hold 500 microns for a minimum of 1 hour.
8) Fully open the valve stem of all stop valves on both sides of gas pipe and liquid pipe
by the hexagonal wrench. If the valve stem hits the stopper, do not turn it any further.
Operating without fully opening lowers the performance and this causes trouble.
9) Refer to 1-3 and charge the prescribed amount of additional refrigerant if needed. Be
sure to charge slowly with liquid refrigerant. Otherwise composition of the refrigerant in
the system may be changed and affect performance of the air conditioner.
10) Remove gauge manifolds and replace service port caps and tighten.
11) Leak test
