Safety Warnings
•
For assistance in performing any disassembly
of the device, please contact Alicat
support (
) for assistance.
•
Operating this device under conditions which exceed
the specifications noted in the manual or specification
sheet could lead to equipment damage or injury.
Installation
The device does not require straight runs of pipes either
upstream or downstream of the device. It can operate in any
orientation whether it's on its side, laid on its back, or inverted
and operating upside down. The only exception to this are
controllers with Rolamite valves. Rolamite valves need to be
oriented vertically, but it can be configured so that the flow
body is connected in a different direction.
Be sure to reference your device dimensions to determine
the size and positions of the mounting holes on the bottom
of the device.
1.
Mount the device so that flow passes through the flow
body as indicated by the arrow or left to right if an arrow
is not present. Refer to the device specifications at
for dimensions and mounting options.
2.
Remove any plastic plugs from the inlet, outlet, or process
connections.
3.
Plumb appropriate lines to the inlet and outlet connections
(and process connection, if present). For pressure
controllers, refer to Appendix C (
) for diagrams
on plumbing specific controllers.
Face seal fittings do not need Teflon tape applied to the
threads.
⚠
Do not use pipe dopes or sealants on the
process connections. These compounds
can cause permanent damage to the device
should they get into the flow stream.
If you are using a fitting that does not have a face seal, use
thread-sealing Teflon tape to prevent leakage around the
connections.
⚠
Do not wrap the first two threads entering the device.
This minimizes the possibility of getting tape into the
flow stream and clogging or damaging the device.
4.
Connect cables to the power and signal connectors (may
not be applicable to battery devices).
5.
Enable power to the device. The device automatically turns
on once the device is connected to power.
⚠
Do not enable power to the device until all necessary
pins have been confirmed to be properly connected.
The device is now ready for use. For further instruction
and operation of your device, please read further.
