DISMANTLING AND REASSEMBLY

Required tools

Medium flat-bladed screwdriver

Small Phillips screwdriver

Dismantling

a) Use the bladed screwdriver to loosen the four

captive screws that secure the Front Bezel and/or

Rear Cover Assemblies (depending on which

component is being replaced) and remove the

cover(s).

b) Remove Power Supply and/or Input PCB

Assemblies by unscrewing the two Phillips

screws and unplug the assemblies from their

connectors.

c) Remove Microprocessor/Display PCB Assembly

by unscrewing the four Phillips screws and

unplug the keypad cable by lifting the locking

arms on the side of the connector and remove

the cable from the connector.

d) Remove the cable hubs by screwing the retaining

nut and removing the hub from the Shell

Assembly.

Reassembly

Check that the gaskets are not damaged and have a

thin layer of silicone grease. If the gaskets are

damaged, replace gaskets.

a) Install the Microprocessor/Display by securing

the assembly with the four Phillips screws and

installing the keypad cable into the connector and

locking it into place by pushing down the two

locking arms on the side of the connector.

b) Install the Power Supply and/or Input PCB

Assemblies into their respective connector and

secure the assemblies with the two Phillips

screws per assembly.

c) Attach cable hubs by installing the gaskets onto

the hubs and insert the hubs into the ports in the

Shell assembly. Secure the hubs by tightening

the nut onto the hub threads.

d) Install the Front Bezel and/or Rear Cover

Assemblies and secure by tightening the four

captive screws per assembly using a bladed

screwdriver.
