Operating Instructions

System Diagnosis:

1. Ensure service ports are clean and free of debris.
2. Close both manifold valves completely.
3. Connect the blue coupler to the low side service port and the red coupler to the high side service port.
4. Start the vehicle, set the A/C to HIGH, and fan to HIGH.
5. Observe gauge readings and refer to your automotive manual for diagnosis (e.g., low/high pressure issues indicate low charge, blockages, or compressor faults).

Charging Refrigerant:

1. Close both manifold valves and turn on the vehicle’s A/C system.
2. Connect the yellow hose to the manifold’s centre port and a vacuum pump (not included) to remove air.
3. Disconnect the vacuum pump and connect the yellow hose to an R1234yf gas supply, following the refrigerant manufacturer’s instructions.
4. Slowly open the low side valve until pressure reaches 42 psi (do not exceed to avoid compressor damage).
5. Close the low side valve when charging is complete.
