Short-Form Operation Instruction
-
Before installing your CEM system it is
important to check:
* flow rate
* fluids to be controlled/evaporated
* up- and downstream pressures
* output signals
* heater temperature
- Watch the red-coloured stickers and make sure
the test pressures are in agreement with normal
safety factors for your application.
-
Check if the piping system is clean. Always install
filters to assure particle free fluids.
-
Install the CEM system and tighten the fittings
according to the instructions of the supplier of
the fittings.
- Check the system for leaks before applying fluid
pressure.
- In systems with corrosive or reactive fluids,
purging with an inert gas is absolute necessary
before use. Complete purging after use with
corrosive or reactive fluids is also required before
exposing the system to air.
-
Apply power to the instruments and allow for
approx. 30 minutes to warm-up and stabilize.
This must be done without flow.
- Your CEM system is now ready for operation.
-
Be sure that your liquid system is free of gas
bubbles. If needed remove the de-aerate plug
on top of the CEM control valve for de-aeration.
