Note：
(1) Follow local codes and regulations when field selecting wires. All the above are the minimum wire sizes.
(2) Transmission cable length is longer than 262ft. (80m), a larger wire size should be selected.
(3) Install main switch and ELB for each system separately. Select the high response type ELB that is activated within
0.1second. Recommended capacity to see outdoor equipment switch capacity.

Test run

Test run should be performed after refrigerant piping, drain, wiring, etc. have been finished.
CAUTION
The air conditioner is provided with a crankcase heater. Ensure that the main power supply has been
turned ON for more than 6 hours ahead of power on preheating. Failure to do so may damage the
compressor.
Do not operate the system until all the check points have been cleared.
(A) Ensure that the stop valves of the outdoor unit are fully opened.
(B) Ensure that the electric wires have been fully connected.
(C) Ensure that the electrical resistance is more than 2MΩ, by measuring the resistance between ground and the
terminal of the electrical parts. If not, do not operate the system until the electrical leakage is found and repaired.
Test run function identification
Operate the thermostat to turn ON the equipment, then proceed test run.
Pay attention to the following items while the system is running.
Do not touch any of the parts by hand at the discharge gas side. Compressor chamber and pipes at the discharge
side will reach temperatures in excess of 194℉（90℃）.
Turn off the power after test run is finished.
●
Installation of the equipment is complete after concluding the test run. For additional information, contact local
technical service center of our company for further information.

<Attentions when Connect the power supply wiring>
1.When connecting the terminal block using stranded wire, make
sure to use the round crimp-style terminal for connection to the
power supply terminal block. Place the round crimp-style
terminals on the wires up to the covered part and secure in place.
2. When connecting the terminal block using a single core wire, be
sure to perform curing.
