Print PageMOUNTING
EPC and EPCD-Series Controllers have mounting holes for convenient mounting to
flat panels. These controllers are position insensitive and can be mounted in any
orientation. The sizes and dimensions for the mounting holes are shown on page 11.
Minimize physical handling of the exposed circuit board of the EPC
or EPCD while installing. Hold the circuit board on its edges while
installing, in order to minimize contact with the exposed circuit board
of the EPC or EPCD.
PLUMBING
Your instrument is shipped with plastic plugs fitted in the port openings.
To lessen the chance of contaminating the flow stream do not remove
these plugs until you are ready to install the device.
Controllers with M5 (10-32) ports have O-ring face seals and require no sealant
or tape. Do not use tape with welded or O-ring fittings.
For non M5 (10-32) ports use thread sealing Teflon® tape to prevent leakage
around the port threads.
Do not wrap the first two threads. This will minimize the possibility of getting
tape into the flow stream and flow body.
Do not use pipe dopes or sealants on the process connections as these
compounds can cause permanent damage to the controller should they get
into the flow stream.
When changing fittings, carefully clean any tape or debris from the port connections.
