IMPORTANT NOTICE-PLEASE READ

FOR MAXIMUM SYSTEM PERFORMANCEVINTAGE AIR RECOMMENDS THE FOLLOWING:

LUBRICANT CAPACITIES

134a SYSTEM R-12 SYSTEM

REFRIGERANT CAPACITIES

CHARGE WITH 2.0 lbs. OF REFRIGERANTCHARGE WITH 1.8 lbs. (1lbs. 12ozs) OF REFRIGERANT

NEW COMPRESSOR - NO ADDITIONAL OIL NEEDEDUSED COMPRESSOR - CONSULT VINTAGE AIR

SERVICE INFO:

SAFETY SWITCHES:

EVACUATE THE SYSTEM FOR 35-45 MINUTES WITH SYSTEM COMPONENTS(DRIER, COMPRESSOR, EVAPORATOR AND CONDENSER) AT A TEMPERATUREOF AT LEAST 85° F. ON A COOL DAY THE COMPONENTS CAN BE HEATEDWITH A HEAT GUN OR BY RUNNING THE ENGINE WITH THE HEATER ONBEFORE EVACUATING. LEAK CHECK AND CHARGE TO SPECIFICATIONS.

YOUR VINTAGE AIR SYSTEM IS EQUIPPED WITH A BINARY PRESSURE SAFETYSWITCH. A BINARY SWITCH (11078-VUS) DISENGAGES THE COMPRESSORCLUTCH IN CASE OF EXTREME LOW PRESSURE CONDITION (REFRIGERANT LOSS)OR EXCESSIVELY HIGH HEAD PRESSURE (406 lb.), 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 lbs., 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.

*18” HEAVY DUTY FAN - 32918-VUF*1955-57 CHEVY FAN SHROUD (V/8 RADIATOR POSITION)- 37155-VCF, OR 1955-57 CHEVY FAN SHROUD (6 cyl. RADIATOR POSITION)-32057-VCF*16” SPAL AUXILIARY CONDENSER FAN PACKAGE - 32007-VUF

THIS KIT DOES NOT CONTAIN HEATER HOSE. YOU MUST PURCHASE 8 FEET OF 5/8” DIA. HEATER HOSE FROM VINTAGE AIR(31800-VUD) OR FROM YOU LOCAL PARTS RETAILER

THE PROPER 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.

w/o FACTORY AIR GEN IV

4 PG 4 OF 25 901257 REV A 10/18/07, 1957 CHEVY w/o AC GEN IV INSTRUCTIONS


SOME VEHICLES MAY HAVE HAD SOME OR ALL OF THEIR RADIO INTERFERENCE CAPACITORS REMOVED. THERE SHOULD BE A CAPACITOR FOUND AT EACH OF THE FOLLOWING LOCATIONS:

1. ON THE POSITIVE TERMINAL OF THE IGNITION COIL2. IF THERE IS A GENERATOR, ON THE ARMATURE TERMINAL OF THE GENERATOR3. IF THERE IS A GENERATOR, ON THE BATTERY TERMINAL OF THE VOLTAGE REGULATOR

MOST ALTERNATORS HAVE A CAPACITOR INSTALLED INTERNALLY TO ELIMINATE WHAT IS CALLED 'WHINING' AS THE ENGINE IS REVVED. IF WHINING IS HEARD IN THE RADIO, OR JUST TO BE EXTRA CAUTIOUS, A RADIO INTERFERENCE CAPACITOR CAN BE ADDED TO THE BATTERY TERMINAL OF THE ALTERNATOR.

IT IS ALSO IMPORTANT THAT THE BATTERY LEAD IS IN GOOD SHAPE AND THAT THE GROUND LEADS ARE NOT COMPROMISED. THERE SHOULD BE A HEAVY GROUND FROM THE BATTERY TO THE ENGINE BLOCK, AND ADDITIONAL GROUNDS TO THE BODY AND TO THE CHASSIS.

IF THESE PRECAUTIONS ARE NOT OBSERVED, IT IS POSSIBLE FOR VOLTAGE SPIKES TO BE PRESENT ON THE BATTERY LEADS. THESE SPIKES COME FROM IGNITION SYSTEMS, CHARGING SYSTEMS, AND FROM TURNING SOME OF THE VEHICLE'S OTHER SYSTEMS ON AND OFF. MODERN COMPUTER OPERATED EQUIPMENT CAN BE SENSITIVE TO VOLTAGE SPIKES ON THEIR POWER LEADS, WHICH CAN CAUSE UNEXPECTED RESETS, STRANGE BEHAVIOR, AND MAY ALSO CAUSE PERMANENT DAMAGE.

VINTAGE AIR STRIVES TO HARDEN THEIR PRODUCTS AGAINST THESE TYPES OF ELECTRICAL NOISE, BUT THERE IS A POINT WHERE A VEHICLE'S ELECTRICAL SYSTEM CAN BE DEGRADED SO MUCH THAT NOTHING CAN HELP.

RADIO INTERFERENCE CAPACITORS SHOULD BE AVAILABLE AT MOST AUTO & TRUCK PARTS SUPPLIERS. THEY TYPICALLY ARE CYLINDRICAL IN SHAPE, A LITTLE OVER AN INCH LONG, A LITTLE OVER A HALF INCH IN DIAMETER, THEY HAVE A SINGLE LEAD COMING FROM ONE END OF THE CYLINDER WITH A TERMINAL ON THE END OF THE WIRE, AND THEY WILL HAVE A MOUNTING CLIP WHICH IS SCREWED INTO A GOOD GROUND ON THE VEHICLE. THE SPECIFIC VALUE OF THE CAPACITANCE IS NOT TOO SIGNIFICANT, IN COMPARISON TO IGNITION CAPACITORS THAT ARE MATCHED WITH THE COIL TO REDUCE PITTING.

THE HEATER CONTROL VALVE IS A NORMALLY OPEN VALVE. IT MUST BE CONNECTED TO THE ECU TO BLOCK WATER FLOW IN AC MODE.

G WHEN INSTALLING GROUND LEADS ON EN IV SYSTEMS, THE BLOWER CONTROL GROUNDAND ECU GROUND MUST BE CONNECTED DIRECTLY TO THE NEGATIVE BATTERY POST.

CARE MUST BE TAKEN WHEN INSTALLING THE COMPRESSOR LEAD, NOT TO SHORTIT TO GROUND. THE COMPRESSOR LEAD MUST NOT BE CONNECTED TO A CONDENSERFAN OR ANY OTHER AUXILIARY DEVICE. SHORTING TO GROUND OR CONNECTING TO A CONDENSER FAN OR ANY OTHER AUXILIARY DEVICE WILL CAUSE SEVERE DAMAGETO THE ECU.

FOR MAXIMUM COOLING AND HEATING, THE AIR LEVER MUST BE IN “INSIDE MODE” POSITION

NOTE: WHEN BATTERY POWER IS FIRST CONNECTED TO THE ECU, THE COMPUTER GOES THROUGH AN INITIALIZATION SEQUENCE. THIS INITIALIZATION MAY TAKE UP TO 30 SECONDS. DURING INITIALIZATION THE BLOWER WILL NOT OPERATE, BUT THE DOORS INSIDE THE UNIT WILL BE OPERATING. A LOW BATTERY OR DISCONNECTING THE BATTERY MAY ALSO TRIGGER A RE-INITIALIZATION. DURING START UP, A LOW BATTERY MAY DROP BELOW 7 VOLTS, TRIGGERING RE-INITIALIZATION.
