Usage Directions
Our R-1234YF refill is designed to work with the A/C Pro R-1234YF Air-Con Reusable Trigger and Gauge (AC00093EN). It’s also compatible with the STP YF Air-Con Reusable Trigger and Gauge (ST00093EN).
- Find the port and remove cap
Always connect and disconnect the coupler of the trigger dispenser with your engine off. Locate your vehicle’s A/C low-side service port and remove the protective dust cap. The low-side port can be found on the larger diameter aluminium tubing, between the evaporator and compressor.
Wearing goggles and gloves, connect the coupler by pressing it on to the low-side service port. But don’t force it. Disconnect the coupler from the low-side port.
Note: If the reading is zero, it indicates there may be an abnormal leak in the system. In this case, don’t attempt to add refrigerant. Seek professional advice.
- Take a reading
Prepare the R-1234YF refill for use by removing the valve protection cap and attaching the gauge. Please note that this product has a left-handed thread. This means you’ll turn it counterclockwise to tighten. Don’t overtighten it. The product contains flammable gas, so keep it away from hot surfaces such as the exhaust manifold. Do not smoke.
Connect the coupler by pressing it on to the low-side service port. Start the engine and set your car’s A/C to max cool, with the system on re-circulate.
Allow it to run for three minutes and ensure the air-conditioner’s compressor is running and the clutch is engaging. Check the gauge reading without pressing the trigger and refer to the pressure gauge chart below for a diagnosis.
If the PSI reading is in the white sector (5-25 psi), charge the system. Using a thermometer can be helpful too. Simply place it in the central dashboard vent inside the vehicle and note the reading.
- Charge your system
Squeeze the trigger to dispense the contents of the R-1234YF refill can. Look and listen for the sound of an abnormal leak. If an abnormal leak is found, stop adding refrigerant.
Hold the can upright to charge and rotate between 12 o’clock and 3 o’clock, continually agitating (shaking). Continue the process, releasing the trigger every 10-15 seconds to check the system pressure against the pressure gauge chart, until the gauge reads ‘Filled’ (green sector, where the system has the correct amount of charge).
A thermometer reading below 15°C indicates the system is charged. During the charging step, system pressure readings should be taken when the compressor is running. Do not overcharge. Please remember to always wear gloves and safety goggles.
FAQs
-
Not only is overcharging your system potentially dangerous, an overcharged system will not function properly and can seriously damage your A/C compressor or other component parts. The symptoms of an overcharged A/C system are exactly the same as a system that is undercharged: warm air out of the vents.
In order to prevent overcharging your A/C system it is imperative to measure the pressure before beginning to charge it. To measure the pressure in the A/C system, attach a pressure gauge to the low-side port. Your car must be running with the A/C system set to maximum cool and the fan in its highest setting.
It is important to note that the proper pressure in your A/C system is dependent on the ambient (outside) temperature. To determine the proper pressure for your system consult a pressure chart, or set the bezel arrow on your pressure gauge to the corresponding ambient temperature and charge to the pressure corresponding to that temperature setting. If the outside temperature is at or below 55°F, do not charge your car. Also, never charge your vehicle above 55psi.
-
In order to properly charge your automotive A/C system the ambient temperature should be above 65ºF. Anything below that does not allow the system to build up enough pressure for a proper reading on your A/C Pro pressure gauge. Because of this, adding refrigerant to your vehicle is not recommended when the ambient temperature is under 65ºF.
-
Your system should be vacuumed if you have replaced a component part in the system, or if the pressure gauge indicates that the A/C system pressure is lower than 10psi.
