NOTE:

This service manual describes technical data of the indoor units.
RoHS compliant products have <G> mark on the spec name plate.
For servicing of RoHS compliant products, refer to the RoHS PARTS LIST (RoHS compliant).

Use the specified refrigerant only

OB367D

Never use any refrigerant other than that specified.

Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the spec labels provided with our products.
We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by
failure to follow the instructions.

SERVICE FUNCTIONS

MSH-GA50VB

MSH-GA80VB

8-1. TIMER SHORT MODE

For service, set time can be shortened by short circuit of JPG and JPS on the electronic control P.C. board.
The time will be shortened as follows. (Refer to 9-6.)

Set time : 1 minute ➔ 1-second
Set time : 3 minute ➔ 3-second (It takes 3 minutes for the compressor to start operation. However, the starting time is

shortened by short circuit of JPG and JPS.)

8-2. P.C. BOARD MODIFICATION FOR INDIVIDUAL OPERATION

A maximum of 4 indoor units with wireless remote controllers can be used in a room.
In this case, to operate each indoor unit individually by each remote controller, P.C. boards of remote controller must be
modified according to the number of the indoor unit.

How to modify the remote controller P.C. board

Remove batteries before modification.
The board has a print as shown below :

NOTE : For modification, take out the batteries and press the OPERATE/ STOP (ON/ OFF) button 2 or 3 times at first.

After modification, put back the batteries then press the RESET button.

Remote controller model : KM04A

J2

J1

The P.C. board has the print “J1” and “J2”. Solder “J1” and “J2” according to the number of indoor unit as shown in Table 1.

After modification, press the RESET button.

Remote controller model : KP0A

J2

J1

Table 1

How to set the remote controller exclusively for particular indoor unit

After you turn the breaker ON, the first remote controller that sends the signal to the indoor unit will be regarded as the
remote controller for the indoor unit.
The indoor unit will only accept the signal from the remote controller that has been assigned to the indoor unit once they are
set. The setting will be cancelled if the breaker has turned off, or the power supply has shut down.
Please conduct the above setting once again after the power has restored.

10

8-3. AUTO RESTART FUNCTION

OB367D

When the indoor unit is controlled with the remote controller, the operation mode, set temperature, and the fan speed are
memorized by the indoor electronic control P.C. board. “AUTO RESTART FUNCTION” automatically starts operation in the
same mode just before the shutoff of the main power. However if the unit is operated in “I FEELCONTROL” mode before
power failure, the operation is not memorized. In “I FEEL CONTROL” mode, the operation is decided by the initial room
temperature.

How to disable “AUTO RESTART FUNCTION”

1Turn OFF the main power for the unit.
2Pull out the electronic control P.C. board, the receiver P.C.

board and the display P.C. board. (Refer to 10-1.2.)

3Solder jumper wire to JR07 on the indoor

electronic control P.C. board. (Refer to 9-6.)

Operation

1If the main power has been cut, the operation settings remain.
2After the power is restored, the unit restarts automatically according to the memory.(However, it takes at least 3 minutes

for the compressor to start running.)

NOTE

•The operation settings are memorized when 10 seconds have passed after the remote controller was operated with the

remote controller.

•If main power is turned OFF or a power failure occurs while AUTO START/STOP timer is active, the timer setting is

cancelled.

•If the unit has been OFF with the remote controller before power failure, the auto restart function does not work as the

power button of the remote controller is OFF.

•To prevent breaker OFF due to the rush of starting current, systematize other home appliances not to turn ON at the same

time.

•When some air conditioners are connected to the same supply system, if they are operated before power failure, the

starting current of all the compressors may flow simultaneously at restart.
Therefore, the special counter-measures are required to prevent the main voltage-drop or the rush of the starting current
by adding to the system that allows the units to start one by one.

TROUBLESHOOTING

MSH-GA50VB
MSH-GA60VB
MSH-GA80VB

9-1. Cautions on troubleshooting

1. Before troubleshooting, check the following:

(1) Check the power supply voltage.
(2) Check the indoor/outdoor connecting wire for mis-wiring.

2. Take care the following during servicing.

(1) Before servicing the air conditioner, be sure to turn OFF the main unit first with the remote controller, and then after

confirming the horizontal vane is closed, turn OFF the breaker and / or disconnect the power plug.

(2) Be sure to turn OFF the power supply before removing the front panel, the cabinet, the top panel, and the electronic

control P.C. board.

(3) When removing the electronic control P.C. board, hold the edge of the board with care NOT to apply stress on the

components.

(4) When connecting or disconnecting the connectors, hold the housing of the connector. DO NOT pull the lead wires.

3. Troubleshooting procedure

(1) Check if the OPERATION INDICATOR lamp on the indoor unit is flashing ON and OFF to indicate an abnormality.

To make sure, check how many times the OPERATION INDICATOR lamp is flashing ON and OFF before starting ser-

vice work.
(2) Before servicing, check that the connector and terminal are connected properly.
(3) When the electronic control P.C. board seems to be defective, check the copper foil pattern for disconnection and the

components for bursting and discolouration.
(4) When troubleshooting, refer to 9-2. and 9-3.

4. How to replace batteries

Weak batteries may cause the remote controller malfunction.
In this case, replace the batteries to operate the remote controller normally.
1 Remove the front lid and insert batteries.

Then reattach the front lid.

2 Press the RESET button with a thin instrument, and

then use the remote controller.

NOTE : 1. If the RESET button is not pressed, the remote controller may not operate correctly.

2. Do not use the leaking batteries.
