 Maintenance

■

ML-7112AH

Have the following items ready when inspecting or replacing the FC-LD of the ML-7112AH:

•

FC-LD (new or refurbished)

•

Phillips screwdriver

1

Unscrew the six screws at the back of 

the Control Unit.

2

Remove the cover on the right side by 

sliding it back about 25 mm and lifting it 

up.
Similarly, remove the cover on the left 

side.

3

Disconnect the Peltier power supply 

relay connector.

･

Before replacing the FC-LD, always turn off the equipment. Wait at least 5 minutes before 

starting work. Performing replacement while the unit is on or immediately after it is turned 

off poses a risk of electric shock, fire, or injury (including burns and blindness).

･

Never attempt to disassemble, repair, or modify the FC-LD yourself.

Slide the cover back 
about 25 mm, then lift 
it.

Control Unit, from right

Cover on right

Relay connector
