Electronic Testing With Oem1437 - New Holland T8010 Manual

Electronic Testing with OEM1437

When performing electronic leak detection with
OEM1437, follow these general guidelines:
1. There must be enough refrigerant in the system
to produce normal pressures (at least 50 psi).
2. Leak test in an area free of wind and drafts.
3. Operate the tractor long enough to circulate the
r e f r i g e r a n t a n d p r o d u c e n o r m a l s y s t e m
pressures.
4. Shut the tractor and system off when leak
testing.
5. Clean oily spots with dry shop cloths; solvents
c a n l e ave a r e s i d u e w h i c h m ay c o n f u s e
OEM1437.
6. Hold the leak detector probe under the point
being checked, since refrigerant is heavier than
air.
7. The probe on the leak detector should never
come into contact with the component being
checked.
8. If OEM1437 indicates a leak, move the probe
away, blow out the area with clean shop air and
verify the leak with the detector.
9. If the leak cannot be found with OEM1437, use
UV florescent leak testing to locate the problem.
10. Repair all leaks and recharge the system.
