11.REPLACEMENT OF THE SERVICE P.C. BOARD MCC-1630

1.Removing the P.C. board

(1)Turn off the power supply of the outdoor unit and allow at least 3 minute for the capacitor to discharge. Confirm that the light of the LED (D800 to D805) fades away.

(2)Remove all the connectors and fast-on terminals connected to the P.C.board.

(Remove the connectors and fast-on terminals by pulling the connector body. Do not pull the wire).

(3)Remove all the screws which secures the P.C.board. (These screws are to be reused after procedure.)

(4)Remove the P.C.board from the BOX.

2.Setting the jumper wires

Modelswitching (J800 to J804, J806)

Since this service P.C. board is available for several models, cut the jumper wires according to the following table. If they are not cut correctly, an error code “L10 or E04”h appears on the remote controller and the operation of the air conditioner is disabled.

3.Installing the P.C. board

(1)Apply thermal grease to the back (heat sink contacting side) of devices IC200 and IC300.

(2)Reuse the insulating sheet. When a small amount of thermal grease is applied to the back of the insulating sheet, it adheres temporarily to the heat sink, which makes it easy to attach the insulating sheet.

(3)Reuse the sub heat sink. Applying thermal grease to the surface and the back of the sub heat sink.

(4)Insert the P.C. board, align the holes of the insulating sheets, semiconductor devices, and heat sinks, and then secure them with screws.

Tighten the screw (A) at the end.

(5)Connect the lead wires according to the wiring diagram sticked on the backside of the panel .
