AC PRO Instructions

Step 1 Turn engine & A/C on

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

Step 2 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 7.

Step 3 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.

Step 4 Remove shipping disk

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

Step 5 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.

Step 6 Read pressure

Rotate the grey dial on the gauge until the center arrow in the “V” on the clear plastic lens points to the ambient (outside) temperature (if temperature is between 85°-115°F, point red arrow at 85°F). Read pressure when the clutch is engaged. If the gauge needle is past the “V”, please read instruction #2. If the gauge needle is before the “V” please read instruction #7. If the compressor is cycled on and the pressure is in the red, do not attempt to recharge. Seek professional help.

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

Step 7 Charge

Pull ring back to disconnect recharge hose from vehicle and screw can on to recharge hose (CAN IS NOW READY FOR USE). DO NOT REMOVE TRIGGER FROM CAN UNTIL EMPTY. Reconnect quick connect to low pressure port. Shake can well. Hold can upright to charge, shaking and rotating from 12 o’clock to 3 o’clock every few seconds. Squeeze trigger to dispense contents.

Continue process, releasing trigger every 10 – 15 seconds to check system pressure with the “V” range on gauge. 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).

Step 8 Completion

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-100CA/ACP-102CA) 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.
