MOISTURE AND LEAD TO PREMATURE FAILURE AND REDUCED PERFORMANCE.
EVACUATE THE SYSTEM FOR 35-45 MINUTES WITH SYSTEM COMPONENTS (DRIER, COMPRESSOR, EVAPORATOR
AND CONDENSER) AT A TEMPERATURE OF AT LEAST 85° F. ON A COOL DAY THE COMPONENTS CAN BE HEATED
WITH A HEAT GUN OR BY RUNNING THE ENGINE WITH THE HEATER ON BEFORE EVACUATING. LEAK CHECK

VINTAGE AIR SYSTEMS ARE DESIGNED TO OPERATE WITH R134a REFRIGERANT
ONLY! USE OF ANY OTHER REFRIGERANTS IS A FIRE HAZARD 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.
REFRIGERANT CAPACITIES FOR VINTAGE AIR SYSTEMS
(FOR OTHER SYSTEMS, CONSULT MANUFACTURER GUIDELINES)
A COMPRESSOR SAFETY SWITCH MUST BE INSTALLED ON EVERY A/C SYSTEM. A BINARY SWITCH
DISENGAGES THE COMPRESSOR CLUTCH IN CASES OF EXTREME LOW PRESSURE (REFRIGERANT LOSS) OR
EXCESSIVELY HIGH HEAD PRESSURE (406 PSI) TO PREVENT COMPRESSOR DAMAGE OR HOSE RUPTURE. A
TRINARY SWITCH COMBINES HI/LO PRESSURE PROTECTION WITH AN ELECTRIC FAN OPERATION SIGNAL AT
254 PSI. COMPRESSOR SAFETY SWITCHES ARE EXTREMELY IMPORTANT SINCE AN A/C SYSTEM RELIES ON
REFRIGERANT TO CARRY LUBRICATION THROUGH THE SYSTEM.
