A) PRE-CHARGE INSTALLATION
1) Start the engine. Inspect the system and determine if the system is operating correctly. Any repairs should be carried out prior to recharging the A/C system.
2) Check the system for refrigerant leaks using appropriate leak detection procedures and tools (stock # 606).
3) Minor leaks from O-ring shrinkage and/or hardening can be repaired instantly by installing RED TEK® LeakStop™ A/C Seal Repair (stock # 401). Leaks in metal lines, condensers, evaporators, fittings, and rubber hoses can be repaired effectively by installing RED TEK® ProSeal™ Advanced Seal Treatment (stock# 402).
4) Use a duct thermometer (stock# 605) to capture and record the center vent temperature. This will supply the installer a temperature reference, allowing the installer to compare before and after passenger compartment temperature readings.
5) Determine the type of refrigerant currently in the a/c system. The OEM tag is located inside the engine compartment. The OEM tag indicates the type and amount of refrigerant in the system. If missing, contact the OEM for further information. This must be determined before initiating a RED TEK® 12a recharge.
6) Evacuation of the refrigerant in the system is recommended prior to installing RED TEK® 12a refrigerant. Recover all existing refrigerants into a suitable approved container and mark appropriately, as FEDERAL REGULATIONS PROHIBIT THE VENTING OF REFRIGERANTS INTO THE ATMOSPHERE. Although RED TEK® 12a is compatible with most existing refrigerants and oils, DO NOT MIX REFRIGERANTS. Mixing refrigerants is illegal in Canada and the US and will not offer the maximum performance available from RED TEK® 12a.
7) Locate low and high side service ports of the A/C system. Generally, the low side service port is covered by a blue dust cap. The high side service port is usually covered by a red dust cap. All current R134a systems are compatible with RED TEK® 134a Installation Kit (stock# 502).
  Note: R-12 A/C systems will require a RED TEK® Low Side Conversion Fitting (stock# 503) and High Side Conversion Fitting (stock# 504 or 505 or 506) which can be purchased separately.
8) Determine the correct amount of RED TEK® 12 a Refrigerant required in the system with the use of the OEM refrigerant information and the RED TEK® 12a Conversion Chart.
9) RED TEK® 12a Refrigerant is installed through the LOW SIDE SERVICE PORT AND IS CHARGED AS A LIQUID INTO A "0" ATMOSPHERIC CONDITION. DO NOT INSTALL INTO A SYSTEM WHERE A HARD VACUUM EXISTS. DANGER!! DO NOT INSTALL ON HIGH SIDE SERVICE PORT.


B) CYLINDER CHARGING PROCEDURE
Follow all RED TEK® 12a safety precautions before initiating charging process.
1) Properly connect Manifold Gauge Set (stock# 601) to RED TEK® 12a cylinder. Cylinders are factory installed with R-12 fittings. Use Cylinder Adaptor (stock# 507) to convert R-12 fittings to R-134a fittings.
2) Locate Low Side Service Port and connect hydraulic coupler by pushing onto male service port making sure hydraulic coupler is fully secured.
3) Locate High Side Service Port and connect hydraulic coupler onto male service port making sure coupler is fully secured.
4) Place refrigerant cylinder on electronic charging scale (stock# 607) and set weight to 0.
5) Start engine and place A/C on maximum settings.
6) Slowly open liquid charging valve allowing refrigerant to enter system slowly.
7) Continue with charging process as determined by the RED TEK® 12a conversion chart and adequate cooling is attained. Low pressure gauge should read between 30 and 38 psi. DO NOT OVERCHARGE! EXCEEDING 60 PSI ON LOW SIDE CAN DAMAGE COMPRESSOR!
8) After RED TEK® 12a charging procedure is completed, turn cylinder valve clockwise until valve is fully closed.
9) Remove hydraulic couplers and charging hoses from low and high side service ports. Store unused RED TEK® 12a refrigerant in a well ventilated place away from open flames.
10) Apply RED TEK® refrigerant identification tags in a highly visible area near charging port.
