Installation and Operation Operation This section contains: • Procedures for connecting service hoses to the vehicle, and • A full sequence program to: — Recycle vehicle refrigerant, — Create a vacuum in the A/C system before recharging, and — Recharge the A/C system with recycled refrigerant. After performing all installation procedures, follow these recommended vehicle service procedures before using your Kool Kare unit for A/C work. Keep the service hoses away from moving or hot engine parts. Service hoses can not withstand high temperatures or severe mechanical stress. • Close tank valves when not in use. Open tank valves may result in refrigerant loss from tank. • Do not use your Kool Kare unit outside of the following limits: — Warmer than 49°C (120°F), — Colder than 10°C (50°F), and or — Relative humidity greater than 80%. • Stabilize your Kool Kare unit to a moderate temperature and inspect for abnormalities. • Contact your <strong>Snap</strong>-on representative before operating if unsure of condition. • Operating your Kool Kare unit with the following conditions may reduce its functionality: — Visible evidence of damage, — Has been subjected to prolonged storage under unfavorable conditions, or — Has been subjected to severe transportation stresses. 2-6
Installation and Operation Preliminary Checks Successful use of your Kool Kare unit depends on several external factors. The following information explains these. Precondition Vehicle The refrigerant in the vehicle A/C system is recovered faster and more completely when the components are warm. 1. Connect the service hoses. To efficiently recover refrigerant, the vehicle should be at normal operating temperature. Run the engine until normal operating temperature is reached, with • The A/C system off, and • The hood lowered as much as possible without damaging or crimping the service hoses. 2. Turn off the engine when normal operating temperature is reached. The unit and vehicle are ready to recover and recycle refrigerant. Allow Adequate Evacuation Time Evacuate the vehicle system for a minimum of 30 minutes. This helps ensure vehicle A/C system is free of non-condensable gases (mostly air) and moisture. 3 Sometimes a small amount of refrigerant is left in the vehicle A/C system that is not practical to recover. If recovery time is too short or if vehicle components are cold, this parasitic refrigerant can expand during a vacuum hold cycle, a leak test, and falsely report a leak condition that does not really exist. Follow Vehicle Manufacturer’s A/C Service Procedures When charging, a slow charge condition may occur due to pressure equalization between your Kool Kare unit and the vehicle A/C system. Finish charging by: • Closing the high-side manifold valve, • Starting the engine, and • Turning the A/C system ON. 3 Never operate the vehicle A/C system with the highside manifold valve open. 3 It is the technicians responsibility to be familiar with vehicle manufacturer recommended service procedures. 2-7
