To Add Oil to the Compressor
Required Materials:
Compressor Refrigeration Mineral Oil 3GS Grade-150 (Do not use synthetic oils use mineral
oil only)
Cut a ¼” refrigeration service hose to form a hose with one fitting end containing a Schrader
valve core depressor and the opposite end of the hose is the open cut end
Straight Blade Screwdriver
Clean 8 ounce container
1. Place approximately 8 ounces of compressor refrigeration mineral oil 3GS, Grade-150
into a container.
2. Place the front panel power switch to the on position.
3. Verify that the manual inlet ball valve on the front panel of the machine is in the closed
position and is capped with an access valve cap.
4. Place the inlet compressor and inlet valve switch to the on positions. Allow the
compressor to operate until a vacuum condition is indicated by the inlet pressure gauge
on the front panel.
5. Place the inlet compressor and inlet valve switch to the AUTO positions. Place the front
panel power switch to the off position.
6. Disconnect the main electrical power from the machine.
7. Open the filter access door of the hood and separate the two halves of the hood fan J5
electrical connector.
8. Remove the three screws along the top of the control panel and the three screws on
both sides of the control panel hood. With a helper, lift the hood up and over the control
panel.
9. Place the open cut end of the modified hose so that it is under the surface of the oil.
10. Remove the valve cap from the compressor oil maintenance access valve AV-3 refer
to figure-9 (next page) for the location of the valve.
11. Connect the fitting service end of the modified hose containing the core depressor
onto the AV-3 access valve. The vacuum in the compressor housing will immediately
begin to draw oil from the container through the hose.
12. View the compressor oil sight glass and disconnect the hose from the AV-3 access
valve when the oil level is from 1/4 to 1/2 full on the sight glass.
CAUTION: Do Not Overfill the compressor with oil.
13. Reinstall the valve cap back to the AV-3 access valve.
14. Reinstall the hood and connect the hood fan electrical connector. Reconnect the main
electrical power back to the machine.
