Thank you for purchasing this evaporator kit from Vintage Air. When installing these components as part of a complete SureFit™ system, Vintage Air recommends working from front to back on the vehicle, installing the condenser kit, hose kit, and compressor first, followed by the wiring, evaporator, and finally the control panel.

Important Notice—Please ReadFor Maximum System Performance, Vintage Air Recommends the Following:
New Vintage Air-supplied Sanden Compressor: No additional oil needed (Compressor is shipped with proper oil charge).All Other Compressors: Consult manufacturer (Some compressors are shipped dry and will need oil added).
NOTE: Vintage Air systems are designed to operate with R134a refrigerant only. Use of any other refrigerant could damage your A/C system and/or vehicle, and possibly cause a fire, in addition to potentially voiding the warranties of the A/C system and its components.
Refrigerant Capacities:Vintage Air System: 1.8 lbs. (1 lb., 12 oz.) of R134a, charged by weight with a quality charging station or scale. NOTE: Use of the proper type and amount of refrigerant is critical to system operation and performance.Other Systems: Consult manufacturer’s guidelines.
Lubricant Capacities:
Safety Switches
Service Info:Protect Your Investment: Prior to assembly, it is critical that the compressor, evaporator, A/C hoses and fittings, hardlines, condenser and receiver/drier remained capped. Removing caps prior to assembly will allow moisture, insects and debris into the components, possibly leading to reduced performance and/or premature failure of your A/C system. This is especially important with the receiver/drier. Additionally, when caps are removed for assembly, BE CAREFUL! Some components are shipped under pressure with dry nitrogen.Evacuate the System for 35-45 Minutes: Ensure that system components (Drier, compressor, evaporator and condenser) are 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.
Your Vintage Air system is equipped with a binary pressure safety switch. A binary switch disengages the compressor clutch in cases of extreme low pressure conditions (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, and should be substituted for use with electric fans. Compressor safety switches are extremely important since an A/C system relies on refrigerant to circulate lubricant.
Bolts Passing Through Cowl and/or Firewall:To ensure a watertight seal between the passenger compartment and the vehicle exterior, for all bolts passing through the cowl and/or firewall, Vintage Air recommends coating the threads with silicone prior to installation.
Heater Hose (Not Included With This Kit):Heater hose may be purchased from Vintage Air (Part# 31800-VUD) or your local parts retailer. Routing and required length will vary based on installer preference.

Important Wiring Notice—Please Read
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 coil.2. If there is a generator, on the armature terminal of the generator.3. 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 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 switching some of the vehicle’s other systems on and off. Modern computer-operated equipment can be sensitive to voltage spikes on the power leads, which can cause unexpected resets, strange behavior, and/or permanent damage.
Vintage Air strives to harden our 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 and truck parts suppliers. They typically are cylindrical in shape, a little over an inch long, a little over a half inch in diameter, and they have a single lead coming from one end of the cylinder with a terminal on the end of the wire, as well as 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 of the points.
Care must be taken, when installing the compressor lead, not to short it to ground. The compressor lead must not be connected to a condenser fan or to any other auxiliary device. Shorting to ground or connecting to a condenser fan or any other auxiliary device may damage wiring, the compressor relay, and/or cause a malfunction.
When installing ground leads on Gen IV systems, the blower control ground and ECU ground must be connected directly to the negative battery post.
For proper system operation, the heater control valve must be connected to the ECU.

On a workbench, install the evaporator rear brackets and hardlines with properly lubricated O-rings (See Figure 9, Page 12, and Figure 19, Page 20).Install the front mounting bracket onto the evaporator using (2) 1/4-20 x 1/2” hex bolts, and tighten as shown in Figure 7, below.Lift the evaporator unit up under the dashboard. Secure loosely to the firewall from the engine compartment side using (2) 1/4-20 nuts and washers (See Figure 7a, below). NOTE: To ensure proper drainage, it is very important that the evaporator is level, both left-right and fore-aft. Check for level on the flat portions of the case around the drain.Using the front evaporator bracket as a guide, mark and drill (2) 3/16” holes in the cowl (See Figure 7b, below).Using (2) #14 x 3/4” sheet metal screws, secure the front evaporator mounting bracket to the inner cowl (See Figure 7b, below).Verify that the evaporator unit is level and square to the dash; then tighten all mounting bolts. NOTE: Tighten the bolt on the firewall first. Then tighten the front mounting bracket sheet metal screws.
NOTE: To ensure a watertight seal between the passenger compartment and the vehicle exterior, for all bolts passing through the firewall, Vintage Air recommends coating the threads with silicone prior to installation.

Install duct hoses as shown in Figure 18, Page 19.Route A/C wires (12 volt/grounds/binary switch/heater valve) through 3/8” grommet as shown in Figure 16, below.Install the control panel assembly. NOTE: Controls must be calibrated for proper operation. Refer to control panel instructions.Plug the wiring harnesses into the ECU module on the sub case. Wire according to the wiring diagrams on Pages 21 and 22.Install the new glove box.Reinstall the glove box door.Using the template provided on Page 28, modify the center console as shown in Figure 17, below.Reinstall all previously removed items.Fill radiator with at least a 50/50 mixture of approved antifreeze and distilled water. It is the owner’s responsibility to keep the freeze protection at the proper level for the climate in which the vehicle is operated. Failure to follow antifreeze recommendations will cause heater core to corrode prematurely and possibly burst in A/C mode and/or freezing weather, voiding your warranty.Double check all fittings, brackets and belts for tightness.Vintage Air recommends that all A/C systems be serviced by a licensed automotive A/C technician.Evacuate the system for a minimum of 45 minutes prior to charging, and perform a leak check prior to servicing.Charge the system to the capacities stated on Page 4 of this instruction manual.See Operation of Controls procedures on Page 23.

Defrost/De-fog Operation
On Gen IV systems with three lever/knob controls, the temperature control toggles between heat and A/C operations. To activate A/C, move the temperature lever/knob all the way to cold and then back it off to the desired vent temperature. For heat operation, move the temperature lever/knob all the way to hot and then adjust to the desired vent temperature. The blower will momentarily change speed, each time you toggle between operations, to indicate the change. NOTE: For proper control panel function, refer to control panel instructions for calibration procedure.
