Changing Minimum Pressure/Check Valve Seals
1.
Be sure the unit is completely off and that no air pressure is in the oil reservoir.
2.
Disconnect, lockout and tagout the power supply to the starter.
3.
Tighten the nut down on the minimum pressure/check valve cover.
4.
Remove the 6 bolts holding the cover onto the separator housing.
5.
Remove the snap ring in the cover.
6.
Remove the components and replace the seals in the minimum pressure/check valve.
7.
Re-assemble valve, including the snap ring.
8.
Tighten the cover down to the separator housing.
9.
Loosen the nut on top of the minimum pressure/check valve .05 to .08 inches.
10. Run the unit and check for leaks.
DANGER
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the starter before removing valves, caps, plugs, fittings, bolts
and filters.
STARTER/CONTROL BOX
(Figure 1-2, page 2) - The following control components are located on the
combination starter/control box.
Hourmeter
- A continuous reading (nonreset) type hourmeter displays the accumulated operating time of
the unit and provides a convenient means for scheduling changes of oil and servicing of filters, separators
and other devices.
CONTROL BOX AND CONTROLLER
- Most of the electrical controls are mounted within the control box
mounted on the compressor package. If service is required, disconnect and lock out the power to the
compressor.
The starter within the enclosure runs and stops the compressor motor. The contactor is controlled by the
electronic controller.
The control transformer steps the voltage down from the compressor line voltage to 120 volts for the
control circuits. Control circuit fuses are located within the enclosure. These protect the control
transformer, wiring and other control components from damage due to short circuits.
The manual switch is used to enable and disable compressor operation. In the OFF position, it removes
power from the electronic controller outputs, and resets the controller. When in the ON position, it
enables the electronic controller to operate the compressor.
