1. OPEN HOOD AND FIND LOWPRESSURE A/C SERVICE PORT
With engine off, open hood and locate the lowpressure A/C service port (on the larger diameter tubing, between the compressor and evaporator). Remove the plastic cap from port and save.
TIP: Visit rechargeac.com for additional help in locating your low-pressure service port. NOTE: For best results, charge under shade. Keep the car doors open while charging (front and back)
2. TURN ENGINE ON. TURN A/C ON HIGH.
Start car and turn on A/C. Set fan to highest setting and temperature to coldest setting. Make sure recirculation mode is selected.
3. ATTACH QUICK CONNECT FITTING
Attach quick connect fitting on end of recharge hose to low-pressure service port identified earlier by pulling the connector ring back as the fitting is pushed on.
NOTE: Our quick connect fitting will attach only onto the low-pressure port.
4. READ PRESSURE COLOR
Without pulling the trigger, look at gauge to see what color section the needle is pointing toward. Depending on the color, determine next step according to grid below:
5. REMOVE PLASTIC SPACER
Disconnect the trigger assembly from service port. Unscrew and remove plastic spacer between trigger assembly and can.
6. CHARGE SYSTEM
Shake can well and screw can onto gauge/ trigger assembly. Connect the quick connect back on the low-side port. Make sure to always hold the can upright (12 o’clock position) before starting to charge. Squeeze the trigger to charge the A/C system. While charging, shake the can up and down, alternating between 12 o’clock and 3 o’clock position. Every 10–15 seconds release trigger. After needle is stabilized, check pressure readings on gauge.
TIP: Read pressure when trigger is released, not while being squeezed. It is typical for gauge to bounce around as the compressor is cycling. If that happens, read the lowest pressure.
7. STOP CHARGING WHEN NEEDLE IN GREEN
BE CAREFUL NOT TO OVERCHARGE YOUR SYSTEM – DO NOT LET NEEDLE MAKE IT INTO THE RED AREA. Once needle makes it anywhere in green zone of the gauge, charging is complete. Do not try to get it to the highest part of the green zone or you risk overcharging. Remove hose from service port and replace plastic cap when finished. Store any unused refrigerant in a cool, dry place, with charging hose securely attached to can.
