For use on A/C-R systems using CFCs, HCFCs, and HFCs in conjunction
with mineral oil, ester oil, alkylbenzene oil, and PAG oil as lubricants.
Not for use with ammonia or lithium bromide systems. Not for use with
ammable refrigerants.

WARNING!
Wear safety goggles when working with refrigerants. Contact with
refrigerants may cause eye injury.
Incorrect use or electrical connections may cause electrical shock.
Read and follow instructions carefully, and take precautions to avoid
electrical shock hazards. All associated devices must be correctly
grounded before energizing circuits.
The normal operating temperature will cause certain external
portions of the pump to be hot to the touch. Do not touch the pump
housing or motor during operation.

CAUTION Before connecting your vacuum pump to an A/C-R system,
remove refrigerant from the system in an accepted manner.
Damage to the pump may occur if evacuation is started while
the system is under high pressure. Robinair recommends the
use of our Refrigerant Recovery and Recycling equipment.
