1.3 MILKING THE SYSTEM FOR OIL
Assembly
| 1. Connect blue extension hose and Checkmate Body
to a clean and dry suction port of an operating system having positive pressure. Never
connect to a liquid or discharge port. 2. Insert Oil Detector Tube RT752C - blue end first. Note:
Alignment bushing is no longer required on kits manufactured after June 1998 |
|
Start Test
| 4. While the system is running, loosen the flare
cap to commence a s-l-o-w bleed. 5. BE PATIENT. Watch for any Oil entering the Tube, Oil will appear as a liquid, wetting the crystals of the Transfer Agent. 6. Allow Oil to pass through the Transfer Agent and deposit a small stain on the Indicator. |
|
Stop Test
| 7. As soon as the Oil hits the Indicator, stop
flow immediately by tightening the flare cap. Close the suction port. 8. Remove entire Checkmate Assembly at extension hose relieving any remaining back pressure. Remove Detector Tube and compare stain on Indicator to the closest color on the chart. |
|
| At times you may experience difficulty coaxing Oil out
of the System. Try the following: (1) Shut down System and commence bleed while suction pressure is rising. Still no Oil? (2) Restart Compressor after a 5 minute rest. Bleed at startup. Be prepared to stop flow immediately. This technique may cause an enormous surge of Oil into the Detector Tube. Oil is always attainable with a de minimis Refrigerant bleed. If required, outlet of Checkmate devise can be adapted to a tank or vessel to capture the Refrigerant bleed. |
