Inverter P.C. Board
for compressor
MCC-1595
ASM-PCB(A3 IPDU)
This board is commonly installed in different models before shipment. Set the dip switch (SW800) setting of the
service board to the switch setting before replacement.
Replacement steps:
(1) Turn off the power supply of the outdoor unit and allow at least 1 minute for the capacitor to discharge.
Confirm that the light of the LED (D800) fades away.
(2) Remove all the connectors and 8 screws of the terminals (
1
) connected to the Compressor IPDU. (Remove
the connectors by pulling the connector body. Do not pull the wire. Screws are to be re-used after
procedure).
(3) Remove all the 5 screws(
2
) which secures the Compressor IPDU to the Heat sink.
(These screws are to be re-used after procedure.)
(4) Remove the Compressor IPDU from the four spacers (
3
) by pinching the top of the spacers by round-nose
pliers.

Insulation sheet (flesh color)
Spread it on the heat sink
Reuse the insulation sheet.
∗
Using a little heat transfer paste on the heat sink
will make easier to install, because the insulation
sheet will stick to the heat sink.
Remove the
PCB
(5) Confirm that no dirt or damage is on the insulation sheet (flesh color) on the heat sink. As it can reduce the
heat transfer efficiency, and can cause a breakdown. If the insulation sheet comes off the heat sink, re-
apply the insulation sheet as shown in the following figure.
