ATTENTION: Although extensive efforts are made to deliver pumps to our
customers completely dry, new pumps may contain residual moisture from their
final DI water test. It is also recommended that a filter be placed on the
discharge side of the pump.
The pump should be operated with clean, dry air or nitrogen. Particulate, water
and oils in the air supply can damage the pump.
2.3 UTILITIES / HOOK-UP FOR REMOTE CONTROLLER
The Champion SL20 pump will work with many types of external control devices.
Trebor’s electronic Pump Control Module, the PC20, is recommended for its
proven, reliable performance. Please consult factory for assistance with other
external control devices.
2.3.a Trebor’s PC20 Electronic Oscillator
The PC20 Series external pump controller requires two separately regulated air
supplies; one to drive the vacuum generator, which fills the pump fluid chambers,
and one that controls pump discharge pressure.
In most booster pump applications the vacuum generators are not required and
may be turned off. (See sect, 2.1)
