Confirm the system switch is at the OFF position.
6.3 Test Running
When the unit is wired according to the standard label, test running should be performed as follows.
(1) Confirm the system switch is at OFF position.
(2) Check to ensure that the electrical resistance is more than 1 mega ohm by measuring the resistance between
earth and the terminal of the electric parts. If not, do not try to operate the unit until the electrical leakage is
found and repaired.
(3) Ensure that the stop valves of the outdoor unit are fully open, and then start the unit.
(4) Check the room temperature if it is higher than 21
o
C DB and 15
o
C WB while on cooling operation.
(5) Switch ON the main power source.
(6) Check the operating voltage, phase balance and operating current.
(7) Check to ensure that the operate panel functions properly.
(8) Check to ensure that the control and protective devices functions properly (refer to Test Running and
Maintenance Record).
