Practicals for RAC Trainees
When trainees replace a part such as a Filter Drier, some oil leaves the system inside the old part. They can put back a measured amount with this injector, using the oil the compressor is built for, such as Mineral Oil in an older system. The oil goes in on the low side while the unit runs.
A second practical joins dye work and a leak test. The class injects UV dye into a demonstration unit such as the Air Conditioning Test Rig, runs it, and checks the joints with a UV lamp. They then spray one suspect joint with Bubble Solution For Leak Detection and compare what the two methods show.
Frequently Asked Questions
Why add oil with an injector instead of pouring it in?
A charged system is sealed and under pressure, so oil cannot be poured in. The injector pushes oil through the service port against the suction pressure, and the auto shut-off valve stops refrigerant escaping while it is connected and removed.
Which oil should go into the system?
Use the oil named on the compressor label or in the service data. Mineral oil suits many older systems, HFC systems usually need POE oil, and car AC systems normally run on PAG oil. Do not mix the types.
How do I keep air and moisture out of the oil?
Fill the injector from a freshly opened, sealed container and purge the air from the connection before injecting. Keep oil containers closed between jobs, since POE and PAG oils draw moisture from the air quickly.
Can it put dye into a car air-conditioning system?
Yes, it handles UV dye as well as oil. Car systems have quick-connect service ports, so a low-side quick coupler goes between the port and the 1/4 in connection before you inject.
Other Oils and Oil-Charging Tools
- POE Oil
- PAG Oil
- Combination Oil Pump (pumps larger amounts of oil against system pressure)
