1.
Check the following before powering on the unit.
1) Check whether the drain pan heater has been properly
installed, wiring has been properly performed, and the removed
components have been returned to the original positions.
2) Check the insulation resistance of the drain pan heater.
• Use the tester (500 VDC) to check that the insulation
resistance between 1 terminal and the ground terminal
and between 2 terminal and the ground terminal is equal
to or higher than 1M
Ω
.
3) Check the continuity of the outdoor unit.
• Use the tester to check that the continuity between the
screw on the front grille and the ground terminal reads 0
Ω
.
• When there is no continuity, retighten the screws securing
the front plate and the bottom frame to increase the area
of contact with the screw. Then, carry out the continuity
test again.
2.
Check the following after powering on the unit.
• Turn on the power supply and check that the temperature of the
drain pan heater will rise.

the temperature rise.
• If the outdoor temperature is high, the heater will not be
energized which is not a failure.
