With 14 Ounce Cans

Fig. 10 Complete Charging Of System:

Never use cans to charge into high pressure side of system (compressor discharge port) or into system at high temperature, as high system pressure transferred into can may cause it to explode.
1. Attach center hose from manifold gauge set to refrigerant dispensing manifold. Turn refrigerant manifold valve completely counterclockwise to open fully, and remove protective cap from refrigerant manifold.
2. Screw refrigerant can into manifold, ensuring gasket is in place and in good condition. Torque can and manifold nuts to 6-8 lb-ft
3. Turn refrigerant manifold valve clockwise to puncture can, and close manifold valve.
4. Loosen charging hose at gauge set manifold and turn refrigerant valve counterclockwise to release refrigerant and purge air from charging hose. When refrigerant gas escapes from loose connection, tighten hose.
5. Fully open refrigerant manifold valve and place refrigerant can into pan of hot water at 125°F to aid transfer of refrigerant gas. Do not heat refrigerant can over 125°F as it may explode. Place water pan and refrigerant can on scale and note weight.
6. On Colt, Colt Vista, Conquest & Eagle Summit, connect a jumper wire across cycling clutch switch terminals. This will engage clutch to compressor.
7. On all models, start engine and turn A/C On, then index blower switch to low position.
8. Low pressure cut-out switch will prevent clutch from engaging until refrigerant is added to system. If clutch does engage, replace switch before continuing.
9. Charge through suction side of system by slowly opening suction manifold valve. Adjust valve so charging pressure does not exceed 50 psi.
10. Adjust engine speed to fast idle of 1300 RPM on 1989 models or 1400-1550 RPM for 1990-1992 models.
11. After specified refrigerant charge has entered system, close gauge set manifold valves, refrigerant manifold valve, and connect wiring.
