KCU401-2 Keeler Cryomatic Service Manual
2. Enclosure & Fittings
Programming Port Cover
The programming port cover may need to be removed in
the event of a firmware upgrade (see Section 6). This is
secured at the rear of the unit by 2 small screws.
Removal of Front Cover
Almost all of the servicing and/or rectification will require
the removal of the front cover. This can be carried out as
follows.
a)
Remove the cryoprobe (if fitted).
b)
Switch off and disconnect gas supply.
c)
Disconnect Cryomatic from the mains electrical
supply.
d)
Disconnect footswitch.
e)
Remove 4 tamper-proof fixings at the rear of the
enclosure using the appropriate tooling.
f)
Withdraw the front cover and carefully disconnect
all connections to the Controller PCB Assembly.
g)
Completely withdraw the front cover.
h)
Re-fitting is the reverse of removal.
Rubber Feet
The rubber feet are secured to the base of the enclosure by
an adhesive layer. They are very robust. If they should
become detached due to rough handling they should be
replaced. Any residual adhesive should be removed using
an alcohol based cleaner before the new foot is firmly
pressed into the square locating recess on the base of the
enclosure.
