ALWAYS WEAR GLOVES AND SAFETY GOGGLES.
1. OPEN HOOD AND FIND LOW-PRESSURE A/C SERVICE PORT
With engine off, open hood and locate the low-pressure A/C service port (on the larger diameter tubing, between the compressor and evaporator). Remove the plastic cap from port and save.
NOTE: For best results charge under shade. Keep the car doors open while charging (front and back).
TIP: Visit ACPRQCQLO COM for additional help in locating your /ow-pressure service port.
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. TURN GAUGE ON & 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.Remove clear plastic battery tab, and tum on the gauge by pressing the On/Off Button. Then, attach quick-connect fitting on end of recharge hose to low-pressure service port by pressing the back of the fitting onto the port.
NOTE: Our quick connect fitting will attach only onto the low-pressure port.
4. READ PRESSURE
Without pulling the trigger, look at gauge to see current pressure of the system. Match this pressure to PSI range/color on indicator above screen. Depending on the color, determine next step according to grid below:
5. REMOVE PLASTIC SPACER
Detach gauge from vehicle by pulling back oo the connection ring to release the coupler. Unscrew and remove plastic spacer between trigger assembly and can.
6. CHARGE SYSTEM
Shake can well, and screw can ooto gauge/ trigger assembly. Reattach the quick-coonect 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 clown, alternating between an upright and sideways posnion. Every 15 secoods release trigger, and check the PSI reading oo the screen.
TIP: It is typical for pressure to bounce around as the compressor is cycling. If that happens, read the lowest pressure.
7. STOP CHARGING WHEN PSI IN GREEN RANGE
BE CAREFUL NOT TO OVERCHARGE YOUR SYSTEM – DO NOT LET PSI READING MAKE IT INTO THE RED RANGE. Once PSI makes it anywhere between 26-50 PSI, check vent temperature. If vent temp is colder, then charging is complete. Do not try to get it to the highest part of the green zooe or you risk overcharging. Remove hose from service port and replace plastic cap when finished. Store any unused refrigerant in a cool, dry place.
