11. TEST RUN

11.1. Pre-test run check items

Before the test operation, refer to the figure and check the following items.

Is the outdoor unit securely installed?

Have you performed gas leakage inspection?

(Connection joints of various pipes (flange connection, brazing))

Is the heat insulation done completely?

(Gas pipe, liquid pipe, drain hose extension on indoor unit side, etc.)

Is the water discharging from drain without any problems?

Are the cables connected correctly?

Are the cables as per specifications?

Is the earth wire connected accurately?

Are there any obstacles blocking the suction gate, and outlet of

the indoor/outdoor units?

Have you filled the specified amount of refrigerant?

Are the stop valves of gas pipe and liquid pipe fully open?

Has the power been supplied to crankcase heater for more than 6 hours?

After checking that the above items are all in order, refer to "11.2. Test operation

method" to test operation the unit. If there are problems, adjust immediately and

recheck.

11.2. Test operation method

Be sure to configure test run settings only when the outdoor unit has stopped

operating.

• Depending on the communication status between the indoor and outdoor units,

it may take several minutes for the system to start operating after settings for the

test run are complete.

• After the test run settings are complete, the outdoor units and the connected

indoor units will start operating. Room temperature control will not activate during

test operation (continuous operation).

• If a knocking sound can be heard in the liquid compression of the compressor,

stop the unit immediately and then energize the crank case heater for a sufficient

length of time before restarting the operation.

Test operation setting method (It can be performed in the following two ways)

• Set with test operation setting (refer to installation manual of indoor unit for further

details) available in the remote controller.

• "Cooling Operation" and "Heating Operation" can be set, using "SELECT" button and

"ENTER" button available on the board of display unit.

(*Make sure to perform the first test operation with cooling operation.)
