Simple Repairs
The module is designed for easy repair. The most frequent repairs such as
plunger seal change and purge valve frit change can be done from the front of
the module with the module in place in the system stack.
These repairs are described in “Simple Repairs” on page 77.
Exchanging Internal Parts
Some repairs may require exchange of defective internal parts. Exchange of
these parts requires removing the module from the stack, removing the covers,
and disassembling the module. The security lever at the power input socket
prevents that the module cover is taken off when line power is still connected.
