TURN ENGINE & A/C ON
Start car and turn on A/C to its highest settings, MAX-COOL.
DETERMINE IF COMPRESSOR IS ON
With A/C on, determine if compressor clutch is engaged (cycled on).
TIP – If the compressor is not cycling on, add ½ can of refrigerant using instruction 4-7.
If the compressor still does not engage, repairs may be necessary.
FIND SERVICE PORT
Locate the vehicle’s low pressure port on the larger diameter aluminum tubing, between the compressor and evaporator. Remove the plastic cap from port and save. Visit our port locator for help locating your low pressure service port.
ATTACH QUICK CONNECT
Attach the quick connect fitting on end of recharge hose to the low pressure port (only port it will fit on to) by simply pushing the fitting on to the low pressure port; you will hear a click. DO NOT PULL TRIGGER as it will release refrigerant from the vehicle.
Check gauge reading on gauge. Read pressure when the clutch is engaged. If the compressor is cycled on and the pressure is in the red, do not attempt to recharge. Seek professional help.
CONNECT HOSE & CAN
Thread recharge hose onto top of can. Connect recharge hose to low pressure port(refer to instruction #4).
Remove top cap and press button to dispense. Hold can upright to charge, shaking and rotating from 12 o’clock to 3 o’clock every few seconds. Release button frequently every 10-20 seconds to check the system pressure. Continue this process until the system is fully charged (PSI is in BLUE zone) or can is empty. BE CAREFUL NOT TO OVERCHARGE YOUR SYSTEM.
It is possible that the can will not be empty when finished. In this case, after disconnecting from vehicle you can leave the recharge hose on the can or remove for future use. Store in a cool dry location. If the can is empty, hold upside down for one minute to dispense any remaining product. Disconnect from vehicle and simply unscrew the recharge hose and discard can. The recharge hose may be used again with another can of EZ Chill® 134a refrigerant. Replace the plastic cap you removed from port during instruction #3.
TIP – It is normal for the recharge hose and gauge to hold pressure after use.
