Usage Directions

1. Start engine and set the air conditioner to maximum cooling with system on re-circulate. Allow to run for 3 minutes. Ensure the air conditioner’s compressor is running and clutch is engaging. If not, use A/C PRO^® R-1234YF recharge product and top up the system.
2. Turn air conditioner & engine off.
3. Turn the valve handle of the recharge hose counter-clockwise until the piercing stem is in the up position. Caution: do not add A/C PRO^® Super Seal through a manifold gauge & hose set. Use only enclosed recharge hose.
4. Carefully screw the top of the Super Seal can onto the end of the recharge hose with the valve hand. Please note: The can and hose use a reverse thread fitting, so you will be screwing it toward the left.
5. Locate vehicle air conditioner low-side service port and remove protective dust cap. The low-side port is located on larger diameter aluminium tubing, between the evaporator and compressor. For further help use the port locator on this website for help finding the low-side port.
6. With air conditioner switched off and whilst wearing goggles & cloth-lined gloves, pull back sleeve on coupler and attach by pressing onto low-side port. Coupler will only fit low-side port – do not force. Make sure fitting is tight. DO NOT ATTEMPT TO CONNECT TO THE HIGH-SIDE PORT AS THE PRESSURE MAY CAUSE THE CAN TO BURST, RESULTING IN SERIOUS INJURY.
7. Holding the can upright, turn the valve handle on the recharge hose clockwise all the way in. You will hear refrigerant moving from the vehicle’s A/C into the can.
8. Wait 10 seconds and turn valve handle clockwise to close valve.
9. Keeping the can connected, shake the can to allow refrigerant to mix with A/C PRO^® Super Seal.
10. Start engine and set air conditioning to maximum cooling with system on re-circulate.
11. Holding the can in an upside-down position and above the service port, turn the valve counter-clockwise. Shake lightly until can is empty.
12. Disconnect the recharge hose from the low-side service port. Turn the valve handle counter-clockwise on the hose until the pushing stem is in the up position. Unscrew can from hose and discard. Be careful of residual oil that may leak out of the hose. Discard can and hose in accordance with national regulations.
13. To prevent A/C PRO^® Super Seal from sealing the service port, immediately flush the charging port with A/C PRO^® R-1234YF recharge product.
14. Allow the air conditioning system to run for 15 minutes to let the Super Seal and refrigerant circulate.
