IMPORTANT NOTICE-PLEASE READ
1956 F-100 FORD TRUCK
HEAT/COOL/DEFORST
FOR MAXIMUM SYSTEM PERFORMANCE VINTAGE AIR RECOMMENDS THE FOLLOWING:
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.
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 YOUR LOCAL PARTS RETAILER.
70053-LFR - RADIATOR
32053-LFF - FAN SHROUD
32518-VUF - 18” FAN
32000-VUF - CLUTCH FAN
SAFETY SWITCHES:
SERVICE INFO:
R134a SYSTEM
LUBRICANT CAPACITIES: NEW COMPRESSOR - NO ADDITIONAL OIL NEEDED
USED COMPRESSOR - CONSULT VINTAGE AIR
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
(PART# 24679-VUS) DISENGAGES THE COMPRESSOR CLUTCH IN CASE OF EXTREME LOW PRESSURE
CONDITIONS (REFRIGERANT LOSS) OR EXCESSIVELY HIGH HEAD PRESSURE (406 PSI.) TO PREVENT
COMPRESSOR DAMAGE OR HOSE RUPTURE. A TRINARY SWITCH (PART# 24678-VUS) COMBINES
HI/LOW 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.
ATTENTION: SYSTEM COMPONENTS: THE COMPRESSOR, EVAPORATOR, CONDENSER & DRIER ARE
CAPPED. CAPS MAY BE UNDER PRESSURE WITH DRY NITROGEN. BE CAREFUL REMOVING CAPS. DO
NOT REMOVE CAPS PRIOR TO INSTALLATION. REMOVING CAPS PRIOR TO INSTALLATION WILL CAUSE
COMPONENTS TO COLLECT 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 AND CHARGE TO SPECIFICATIONS.
CHARGE WITH 1.8 lbs.
(1 lbs. 12 oz) OF REFRIGERANT

BEFORE STARTING THE AIR CONDITIONER INSTALLATION, CHECK FOR
PROPER OPERATION OF ALL COMPONENTS (RADIO, LIGHTS, WIPERS, ETC.).

SOLUTION:
THE THERMOSTAT IS SET TOO COLD AND THE EVAPORATOR IS "ICING UP" AND RESTRICTING
AIR FLOW. ALLOW THE ICE TO MELT AND SET THE WARMER (COUNTERCLOCK-
WISE) 1/8 OF A TURN EACH ADJUSTMENT UNTIL THE SYMPTOMS DIMINISH.
ADJUST THE

THE SYMPTOMS DIMINISH.
2.) A/C NEVER GETS COLD AND THE COMPRESSOR CLUTCH CYCLES FREQUENTLY.
THE THERMOSTAT IS SET TOO WARM. SET THE COLDER (CLOCKWISE)
1/8 OF A TURN EACH ADJUSTMENT, UNTIL THE DESIRED AIR TEMPERATURE IS REACHED. ADJUST
IN 1/8" INCREMENTS TOWARD COLDER UNTIL THE DESIRED AIR TEMP IS REACHED.
AVOID SETTING THE THERMOSTAT TOO COLD.
3.) THE A/C NEVER GETS COLD, SOMETIMES EVEN BLOWS HOT, AND THE A/C COMPRESSOR
CLUTCH INFREQUENTLY CYCLES OFF.
THE HEATER MAY BE ON AT ALL TIMES.
CAREFULLY FEEL THE HEATER HOSE BETWEEN THE
EVAPORATOR AND THE HEATER CONTROL VALVE. THIS HOSE SHOULD NOT BE HOT IN THE A/C MODE.
IF THE HOSES ARE HOT ....
A)- THE HEATER CONTROL VALVE MAY BE INSTALLED BACKWARDS. CHECK THE FLOW DIRECTION
ARROW ON THE VALVE AGAINST THE ILLUSTRATION IN YOUR INSTALLATION INSTRUCTIONS.
B)- IF CABLE OPERATED: THE VALVE MAY BE MISADJUSTED.
C)- IF VACUUM OPERATED: IT MAY BE GETTING VACUUM AT ALL TIMES (CHECK ELECTRIC SOLENOID).
D)- THE HEATER CONTROL VALVE MAY BE INSTALLED IN THE WRONG HOSE. IT MUST BE INSTALLED
IN THE HOSE COMING FROM THE INTAKE MANIFOLD ENGINE COOLANT PRESSURE PORT.
• THE AIR CONDITIONER THERMOSTAT CONTROLS COIL TEMPERATURE. ROTARY TYPE THERMOSTATS ARE
SHIPPED ADJUSTED FULLY COLD (CLOCKWISE). IN THE MAJORITY OF CASES THE A/C WILL OPERATE
