15. TEST RUNNING
When installation is completed, perform test run according to the following procedure, and hand over the system to the customer.
Perform test run regarding indoor units one by one in order, and confirm that the electrical wiring and the refrigerant piping are
correctly connected.
Test run should be performed according to the "Test Run Procedure" on next page.

WARNING:
Do not operate the system until all the check points have been cleared:
•
Check to ensure that the electrical resistance is more than 1 MΩ, 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. Do not
impress the voltage on the terminals for transmission 1 and 2.
Check to ensure that the stop valves of the outdoor unit are fully opened, and then start the system.
-
- Check to ensure that the switch on the main power source has been ON for more than 12 hours, to warm the compressor oil by
the oil heater
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, since the compressor chamber and the pipes at the discharge
-
side are heated higher than 90°C.
DO NOT PUSH THE BUTTON OF THE MAGNETIC SWITCH(ES), it will cause a serious accident.
-
Do not touch any electrical components for more than three minutes after turning OFF the main switch
•
Confirm that the gas line stop valve and the liquid line stop valve are fully open.
•
Confirm that the leakage of the refrigerant does not exist. The flare nuts are sometimes loosened by vibration during
•
transportation.
Check that the refrigerant piping and the electrical wiring conform to the same system.
•
Confirm that the dip switch setting on the printed circuit board of the indoor units and the outdoor units are correct.
•
Check whether or not the electrical wiring of the indoor units and the outdoor units are connected as shown in the chapter
•
ELECTRICAL WIRING".

CAUTION:
Confirm that field-supplied electrical components (main switch fuse, fuse-free breaker, earth leakage breakers, wires, conduit
-
connectors and wire terminals) have been properly selected according to the electrical data given in the Technical Catalog of
the unit and ensure that the components comply with national and local codes.
