Oil Injection Orifices - These orifices are installed in the oil return lines and control the flow
rate of oil returned to the compressor.
Pressure Gauge - Indicates gas pressure in the supply line. When the compressor is not
running, the gauge located on the compressor’s front panel shows the equalization pressure.
Supply Gas High Temperature Thermistor - Senses discharge gas temperature. It causes
the compressor to shut down if the temperature of the high-pressure helium from the
compressor is too high.
Water High Temperature Thermistors - Sense water temperature. One each is located in the
“water in” line and in the “water out” line. They provide a warning if the inlet or the outlet water
temperature is too high. High outlet water temperature indicates low water flow.
Water In and Out Fittings – F-70H is fitted with two (2) ½" MNPT and F-70L is fitted with two
