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.
QUICK START GUIDE 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.
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.

NOTE: Our quick connect fitting will attach only onto the low-pressure port.
TIP: Visit acprocold.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).
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:

• System low on refrigerant. Continue on to step
5 to begin recharging process.
• If needle is within the green section, system is properly
charged and no additional refrigerant is needed.
• Malfunctioning A/C when needle within green indicates
other system problems besides low refrigerant.
• No additional refrigerant needed.
• Confirm compressor clutch is engaged when checking
pressure (see image below).
• If compressor is not engaged, ensure car is running and
A/C is turned on.
• If needle is in the red and compressor is cycling on,
do not add refrigerant. System needs to be serviced by
technician.

WHAT IT MEANS
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.
