-2. Fan IPDU P.C. Board (MCC-1610)

Replacement steps:
[Remove PCB]

(1) Turn off the power supply of the indoor unit and allow at least one minute for the capacitor to discharge.

Confirm that the light of the LED (D640) fades away.

(2) Remove all the connectors which are connected to the FAN IPDU. (Remove the connectors by pulling

the connector body. Do not pull the wire, because there are some rocks in connector).

(3) Remove all the five screws (a) which secures the FAN IPDU to the Heat sink.(These screws are to be

re-used after procedure.)

(4) Remove the Fan IPDU from four PCB spacer (b).

[Set PCB]

(5) Confirm that no dirt or damage is on the sub heat sink.

And don’t forget to set sub heat sink.

As it can

reduce the heat transfer efficiency, and cause a breakdown.

(6) Screw the FAN IPDU to the heat sink using the five screws that were removed in step (3). If the screws

are loose, the effected component will generate heat, and cause in to breakdown. Do not use an electric

driver or an air driver, as it can cause component damage. The torque of 5 screws (IC701, DB509,

DB510 and Q590) is “0.55Nm”.

(7) Re-connect the connectors. Be sure that all the connectors are connected correctly and securely

inserted.

(8)Install the cover, then turn on the supply. Check the operation.

10-3. N/F P.C. Board (MCC-1551) Replacement Procedure

(1) Turn off the power supply of the indoor unit
(2) Remove all the connectors and remove earth lead from metals. (Remove the connectors by pulling the

connector body. Do not pull the wire, because there are some rocks in connector).

(3) Remove the Fan IPDU from four PCB spacer (a).

(4) After changing PCB, re-connect the connectors. Be sure that all the connectors are connected correctly

and securely inserted. And Screw to earth lead.

(5) Install the cover, then turn on the supply. Check the operation.
