NOTE: No more than 200 fluid oz of oil should be in a 30 lb recovery cylinder at
any given time.
NOTE: Recovery cylinder should be marked with type of oil and refrigerant to be
used. A tag with a log of oil added and removed should be attached to each cylinder.
Filling empty cylinder with oil
- Pull a vacuum on cylinder.
- Attach oil hose to liquid side of recovery cylinder.
- Attach low side of manifold set to vapor side of recovery cylinder (loosely).
- Attach middle of manifold set to nitrogen bottle.
- Set nitrogen pressure to 5-10 psi.
- Purge manifold set with nitrogen, tighten fitting on recovery cylinder.
- Open vapor side of cylinder (filling cylinder with nitrogen).
- Open liquid side of cylinder. Purge oil hose with nitrogen BEFORE placing into oil.
- Place oil hose into oil. Close vapor side of recovery cylinder.
- Turn off nitrogen cylinder. Disconnect middle of manifold set from nitrogen and attach to vacuum pump.
- When bubbling through oil has ceased or slowed significantly, close liquid side of cylinder.
- Turn on vacuum pump. Slowly open vapor side of recovery cylinder.
- Slowly open liquid side of cylinder. This will begin to suck oil into the recovery cylinder.
- Carefully monitor oil level. When approximately one inch remains in the bottom of the can, close liquid valve of recovery cylinder. Allow oil in hose to drain back into can.
- Close vapor side of recovery cylinder. Turn off vacuum pump.
- Disconnect yellow hose from vac pump. Attach to cylinder of refrigerant to be used.
- Purge manifold set with small amount of refrigerant.
- Add approximately 1.5 lbs of liquid refrigerant. Close vapor side valve.
- Make note of amount of oil added and date.
Adding oil to partially filled cylinder
- Recover refrigerant from vapor side of oil cylinder.
- Follow oil filling procedure from step two.
Adding oil to system
- Attach oil hose to recovery cylinder.
- Attach other side of oil hose to low side of system.
- Recover small amount of refrigerant from low side through hose, retighten hose on cylinder.
- With system running, crack open liquid side valve of recovery cylinder. Carefully monitor system pressures and amount of oil used (using refrigerant scale).
- Close liquid side valve.
- Make note of amount of oil subtracted and date.
OR
- Use oil hose and deliver desired amount of oil into QwikInjector (QT2510) by slowly opening liquid side valve.
- Use QwikInjector (QT2510) per instructions.
