IMPORTANT NOTICE-PLEASE READ
FOR MAXIMUM SYSTEM PERFORMANCE VINTAGE AIR RECOMMENDS THE FOLLOWING:
LUBRICANT CAPACITIES:
134a SYSTEM
CHARGE WITH 1.8 lbs.
(1lbs. 12ozs) OF REFRIGERANT
NEW COMPRESSOR - NO ADDITIONAL OIL NEEDED
USED COMPRESSOR - CONSULT VINTAGE AIR
SERVICE INFO:
SAFETY SWITCHES:
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.
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.
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.

NOTE: THE DRIER IS USUALLY MOUNTED WHERE YOU HAVE ROOM FOR IT.
JUST REMEMBER TO MOUNT IT IN THE COOLEST SPOT POSSIBLE AND
VERTICALLY SO THE SIGHT GLASS IS DIRECTLY ON TOP. (NOT NEXT TO
THE EXHAUST MANIFOLD). IT CAN BE MOUNTED INSIDE THE VEHICLE
AS WELL.
PUSH THE 5/16" I.D. HOSE ONTO THE 90° #6 FITTING. (SEE HOSE ROUTING ILLUSTRATION ON PG. 7). INSTALL
THE FITTING ONTO THE EXPANSION VALVE (FINGER TIGHT). PUSH THE 1/2" I.D. HOSE ONTO THE STRAIGHT
#10 FITTING, AND INSTALL THE FITTING ONTO THE #10 LINE ON THE EVAPORATOR. (SEE HOSE ROUTING
ILLUSTRATION PG. 7).
AT THIS TIME, TRY TO DETERMINE WHERE YOU WANT YOUR LINES TO GO THRU THE FIREWALL. MOVE THE
HOSES TO THAT POINT. HOLD THE FITTINGS UP TO THEIR RESPECTIVE HOSES, AND DETERMINE IF THE HOSES
WILL CONFORM TO THE LOCATION FOR THE BULKHEAD FITTINGS OR OPTIONAL BULK-HEAD PLATE (VINTAGE
AIR PART# 34215-VUQ OR 34217-VUQ). THE 1/2" HOSE IS HARD TO BEND AT A SHARP ANGLE, AND THE
FITTINGS TAKE UP A CERTAIN AMOUNT OF SPACE. BEFORE YOU DRILL HOLES IN YOUR FIREWALL, MAKE SURE
THAT YOU CAN MAKE THE HOSES FIT WHERE YOU HAVE PLANNED. THE ENGINE COMPARTMENT APPEARANCE
IS A CONSIDERATION WHEN CHOOSING THIS LOCATION.
WHEN YOU HAVE DECIDED WHERE YOU WANT TO PLACE YOUR BULKHEAD FITTINGS, MARK THESE POINTS
WITH A GREASE PENCIL, AND MAKE A TEMPLATE FROM THE INSIDE, LOCATING WHERE THE HOLES WILL BE
CUT WITH THIS TEMPLATE, LOCATE THE SAME POINTS ON THE OUTSIDE OF THE FIREWALL. MARK THESE
POINTS WITH A GREASE PENCIL.
DETERMINE THE BEST LOCATION FOR THE DRIER THAT WILL ALLOW ADEQUATE ROOM FOR THE HOSE AND
FITTINGS THAT CONNECT THE DRIER TO THE BULKHEAD FITTING.
MOUNT THE DRIER. (KEEP THE DRIER CAPPED AS MUCH AS POSSIBLE. IF YOU MUST SCREW THE FITTING TO
THE DRIER, TAPE IT CLOSED).
AT THIS POINT, CUT HOLES FOR BULKHEAD FITTINGS, AND INSTALL THEM.
USING THE HOSE ROUTING ILLUSTRATION AS A GUIDE, ROUTE REMAINING A/C LINES, AND CUT TO LENGTH.
AT THIS TIME, YOU SHOULD HAVE THE REFRIGERATION HOSES CUT TO THEIR PROPER LENGTH. PAY CLOSE
ATTENTION TO THE ORIENTATION OF ANY HOSE WITH TWO ANGLED FITTINGS. ANY HOSE WITH TWO
ANGLED FITTINGS MUST BE MARKED FROM THE HOSE TO THE FITTINGS TO ASSURE THEYWILL REMAIN IN THIS
POSITION AFTER CRIMPING. THE RUBBER HOSE IS ONLY CAPABLE OF A MINIMAL AMOUNT OF TWIST TO AID
ALIGNMENT.
REMOVE HOSES AND CRIMP ENDS. IF YOU DO NOT HAVE ACCESS TO THE PROPER EQUIPMENT, VINTAGE AIR
RECOMMENDS TAKING THEM TO A QUALIFIED A/C SERVICE CENTER FOR CRIMPING. (SEE CRIMPING
INSTRUCTIONS SUPPLIED WITH THE HOSE KIT).
WITH THE EVAPORATOR TRIAL FIT COMPLETE, REMOVE THE UNIT AND LOWER INTO THE VEHICLE.
AFTER CRIMPING HOSES, LOCATE THE #6 A/C HOSE WITH THE 90° FITTING. LUBRICATE A #6 O-RING AND
THE THREADS ON THE FITTING, AND INSTALL ON THE EXPANSION VALVE. TIGHTEN CAREFULLY. REFER TO
FIGURES 3 & 3A, PAGE 8.
LOCATE THE #10 A/C HOSE WITH THE STRAIGHT FITTING. LUBRICATE A #10 O-RING AND THE THREADS ON
THE FITTING, AND INSTALL ON THE #10 LINE OF THE EVAPORATOR. TIGHTEN CAREFULLY. REFER TO FIGURES
3 & 3A, PAGE 8.
WRAP THE #10 FITTING WITH PRESS TAPE, AND COVER ALL EXPOSED METAL SURFACES. (DO NOT WRAP
THE #6 HOSE, FITTING, OR THE HEATER CORE TUBES). SEE FIGURE 3, PAGE 8.

THERMOSTAT ADJUSTMENT
AIR CONDITIONING ADJUSTMENTS:
ADJUSTING A/C THERMOSTAT:
THE AIR CONDITIONER THERMOSTAT CONTROLS COIL TEMPERATURE. THERMOSTATS ARE SHIPPED ADJUSTED
FULLY COLD (CLOCKWISE). IN THE MAJORITY OF CASES, THE A/C WILL OPERATE CORRECTLY AS SHIPPED.
TURNING THE KNOB TO THE RIGHT (CLOCKWISE) MAKES THE SYSTEM OPERATE COLDER. IF THE THERMOSTAT
IS SET TOO COLD, THE EVAPORATOR COIL WILL "ICE UP," MEANING THE EVAPORATOR COIL IS RESTRICTED
WITH ICE, AND COLD AIR FLOW WILL BE REDUCED.
TURNING THE KNOB TO THE LEFT (COUNTERCLOCKWISE) MAKES THE SYSTEM OPERATE WARMER. THE
COMPRESSOR CLUTCH WILL CYCLE OFF FREQUENTLY. THE EVAPORATOR COIL WILL NOT GET AS COLD AND
THE AIR TEMPERATURE WILL NOT BE AS COLD.
1.) SYMPTOM: THE A/C WORKS WELL AT FIRST, THEN QUITS COOLING. THE AIRFLOW FROM THE VENTS IS LOW,
AND THE COMPRESSOR CLUTCH CYCLES INFRQUENTLY.
SOLUTION: THE THERMOSTAT IS SET TOO COLD AND THE EVAPORATOR IS "ICING UP" AND RESTRICTING
AIRFLOW. ALLOW THE ICE TO MELT AND SET THE THERMOSTAT WARMER (COUNTERCLOCKWISE) 1/8 OF A
TURN EACH ADJUSTMENT UNTIL THE SYMPTOMS DIMINISH.
2.) SYMPTOM: A/C NEVER GETS COLD AND THE COMPRESSOR CLUTCH CYCLES FREQUENTLY.
SOLUTION: THE THERMOSTAT IS TOO WARM. SET THE THERMOSTAT COLDER (CLOCKWISE) 1/8 OF A TURN
EACH ADJUSTMENT, UNTIL THE DESIRED AIR TEMPERATURE IS REACHED. AVOID SETTING THE THERMOSTAT
TOO COLD.
3.) SYMPTOM: THE A/C NEVER GETS COLD, SOMETIMES EVEN BLOWS HOT, AND THE A/C COMPRESSOR CLUTCH
INFREQUENTLY CYCLES OFF.
SOLUTION: 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.
