ACP Instructions 1


Start car and turn on A/C to its highest settings, MAX-COOL.

ACP Instructions 2


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 7.

If the compressor still does not engage, repairs may be necessary.

ACP Instructions 3


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 additional help locating your low pressure service port.

ACP Instructions 4


Unscrew trigger dispenser from can and set can aside. Remove red & white shipping disk by unscrewing and discard.

ACP Instructions 5


Attach the quick coupler fitting on end of recharge hose to the low pressure port (only port it will fit on to) by pulling the connector ring back as you push the fitting on to the low pressure port. DO NOT PULL TRIGGER as it will release refrigerant from the vehicle.

ACP Instructions 6


Your gauge will look like either one of these.

Check gauge pressure when the compressor cycles on. Rotate the dial so the arrow/indicator on the gauge face points to the current ambient (outside) air temperature. If the pressure is below the range outlined by the “V”, continue per below charging instructions. If the compressor is cycled on and the pressure is in the red do not attempt to recharge. Detach quick-connect fitting from low-pressure service port and seek professional help.

ACP Instructions 7


Shake can well. Screw can into hose assembly and reconnect quick-connect to low pressure port. Squeeze the trigger of the charging device to begin charging. Notice the gauge needle goes to zero to indicate no pressure reading is being taken during charging. While charging, rotate the can between 12 o’clock and 3 o’clock every 2 to 3 seconds while continually shaking the can back and forth. Every 10-15 seconds, release the trigger to check the pressure reading. Notice the gauge needle shows the A/C system pressure. System is charged when the gauge needle reaches inside the red “V” area marked on the lens. Frequently check the air blowing out of the dashboard vent. Continue this process until the system is fully charged (PSI in GREEN zone) or can is empty. BE CAREFUL NOT TO OVERCHARGE YOUR SYSTEM.

NOTE: For cans purchased without charging hoses, follow instructions on charging hose (purchased separately).

ACP Instructions 8


It is possible that the can will not be empty when finished. In this case after disconnecting from vehicle simply leave the recharge hose on the can and 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 can and discard. The recharge hose may be used again with another can of A/C Pro refrigerant or any R-134a can with a threaded cap. Replace the plastic cap you removed from port during instruction #3. For California Version (Model ACP-102CA/ACP-105CA). DO NOT DISCARD. Return to place of purchase for deposit.

TIP – It is normal for the recharge hose and gauge to hold pressure after use.
