Enviro-Care Demonstration
1. Find the low side of the a/c system. R-134a is the bigger line but smaller fitting. On R-12 systems the low side is the biggest of the two lines with the bigger fitting. Adapters can only connect to the proper fittings. All auto a/c systems have low sides.
2. Connect kit to the low side. Use appropriate hose/adapter. To get a correct reading on the gauge the car must be running and the a/c system must be set on maximum.
3. Charge a/c system with appropriate Enviro-Care products. Keep can upside down, first turn the tap fully to perforate can then open tap fully in other direction to charge system. Allow one minute for can to empty completely. Optimum psi pressure for any auto system is between 30-45 psi. Use gauge to charge to proper level.
The process is the same for all products or any additional cans. Please see our tips section for useful information on how to use your system more efficiently.
