Installation Instructions
11
(A) Check to ensure that the stop valves of the outdoor unit are fully opened.
(B) Check to ensure that the electric wires have been fully connected.
(C) Check to 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 appliance, and then proceed with the test run.
Pay attention while the system is running.
Do not touch any of the parts by hand at the discharge gas side, since the compressor chamber and the pipes at the
discharge side are will be at temperatures higher than 194℉（90℃）.
Test run should be performed only after refrigerant piping, drain, wiring, etc. have been completed.
The air conditioner is provided together with a crankcase heater. Check to ensure that the switch
on the main power source has been ON for more than 6 hours ahead of power on preheating,
otherwise it might damage the compressor!
Do not operate the system until all of the following check points have been cleared.
Turn off the power after test run is finished.
Installation of the appliance is generally finished after the above operations are done. If you still have any trouble,
please contact the local technical service center of our company for further information.

Electrical Data
Max. Running Current (A): REFER TO NAMEPLATE
Note：
(1) Follow local codes and regulations when selecting field wires. All of the above are the minimum wire size.
(2) When transmitting cable length is longer than 262ft. (80m), the next larger wire size should be selected.
(3) Install a main switch and ELB for each system separately. Select the high-response type ELB that activates within 0.1
second. Recommended capacity is based on outdoor machine switch capacity.
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, secure in place.
2. When connecting the terminal block using a single-core wire, be
sure to perform proper curing.
