8. Test Run

Test run should be performed according to "Installation & Maintenance Manual" of the outdoor unit or
wired remote controller.
WARNING
!
•
Do not operate the system until all need to add a table with the checks to be made.
(a) Check to ensure that the electrical resistance is more than 1 megohm, 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.
(b) Check to ensure that the stop valves of the outdoor unit are fully opened, and then start the system.
(c) 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 crankcase heater.
•
Pay attention to the following items while the system is running.
(a) 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.
(b) DO NOT PUSH THE BUTTON OF THE MAGNETIC SWITCH (ES). It will cause a serious accident.

WARNING
!
•
Use the ELB(Electric Leakage Breaker) which is above medium reaction speed (residual-current circuit
breaker, action time of 0.1s or less). Otherwise, it may lead to electric shock or fire.
•
Run the cables through an appropriately sized conduit completely sealing the openings on either
ends.

NOTES:
•
Follow local codes and regulations when selecting field wires.
•
The wire sizes marked with *1 in the above table are selected at the maximum current of the unit
according to the European Standard, IEC 60335-1. Use the wires which are not lighter than the
ordinary tough rubber sheathed flexible cord (code designation H05RR-F) or ordinary polychloroprene
sheathed flexible cord (code designation H05RN-F) when get power from outside.
