Refrigerant Oil: Service and Repair

When using any R12 or R134a Recovery Station equipped with a refrigerant monitor (PureGuard or PureGuard 2), always inject oil and charge refrigerant into vehicles through the HIGH SIDE ONLY. Injecting oil or charging refrigerant through the low side WILL damage the PureGuard and PureGuard 2.


CAUTION: Never open low side manifold valve when injecting oil.
