YOUR VINTAGE AIR SYSTEM IS EQUIPPED WITH A BINARY PRESSURE SAFETY SWITCH. A BINARY SWITCH

(11078-VUS) DISENGAGES THE COMPRESSOR CLUTCH IN CASE OF EXTREME LOW PRESSURE CONDITION

(REFRIGERANT LOSS) OR EXCESSIVELY HIGH HEAD PRESSURE (406 PSI), TO PREVENT COMPRESSOR DAMAGE

OR HOSE RUPTURE. A TRINARY SWITCH (11076-VUS) COMBINES HI/LO PRESSURE PROTECTION WITH AN

ELECTRIC FAN OPERATION SIGNAL AT 254 PSI

., AND MAY BE SUBSTITUTED FOR USE WITH ELECTRIC

CONDENSER FANS. COMPRESSOR SAFETY SWITCHES ARE EXTREMELY IMPORTANT SINCE AN A/C SYSTEM

RELIES ON REFRIGERANT TO CARRY LUBRICATION THROUGH THE SYSTEM.

VINTAGE AIR SYSTEMS ARE DESIGNED TO OPERATE WITH R134a

REFRIGERANT ONLY! USE OF ANY OTHER REFRIGERANTS RISKS A DANGER OF FIRE

AND COULD DAMAGE EITHER YOUR AIR CONDITIONING SYSTEM OR YOUR VEHICLE.

USE OF ANY OTHER REFRIGERANTS WILL VOID ALL WARRANTIES OF

THE AIR CONDITIONING SYSTEM AND COMPONENTS. USE OF THE PROPER

TYPE AND AMOUNT OF REFRIGERANT IS CRITICAL TO PROPER SYSTEM

OPERATION. VINTAGE AIR RECOMMENDS OUR SYSTEMS BE CHARGED BY

WEIGHT WITH A QUALITY CHARGING STATION OR SCALE.
