  • Provides accurate pressure reading and fill
  • 24” braided charging hose gives easier access to hard-to-reach ports
  • Foolproof metal coupler only connects to low side ports in R-134a systems

Usage Directions

FOR USE WITH A/C PRO® R-134a AUTO AIR-CON RECHARGE (AC02001EN)

  • Compatible with STP Auto Freeze Air-Con Recharge (ID02000EN) and STP EZ CHILL Auto Air-Con Recharge (ID02001EN)
  1. Find port & leak check – Do not start the engine. Always connect and disconnect with engine off. Locate the A/C low-side service port – use the port locator on this website for help finding the low-side port. You will not be able to connect to the high side port in error. Unscrew the dust cap and connect the trigger dispenser. If reading is zero, this indicates there may be an abnormal leak on the system. DO NOT ATTEMPT TO ADD REFRIGERANT. SEEK PROFESSIONAL ADVICE.
  2. Measure – Start the engine. Set A/C to maximum cooling and allow to run for 3 minutes. Check that the A/C compressor is running, listening and watch the clutch engaging. Check the gauge reading and compare to chart below: below:

  1. Charge –Remove coupler from port with engine switched off. Screw container into trigger dispenser – do not overtighten. Follow detailed instructions on A/C Pro® recharge container. Reconnect the coupler to the low-side port and restart the engine. Squeeze the trigger to charge to the level shown on chart below. Release trigger every 10-15 seconds to check refrigerant level.

IMPORTANT: ALWAYS WEAR GLOVES AND SAFETY GOGGLES WHEN RECHARGING YOUR SYSTEM.

Keep out of reach of children.

FAQs

  • If your A/C is not blowing cold you probably are low on refrigerant due to a leak. Most leaks are in rubber components such as O-rings, hoses and gaskets.

  • We recommend using a pressure gauge to determine an accurate fill. A/C Pro®’s colour-coded gauges indicate whether you should continue filling (charging) or not.

  • The best way to find leaks is with our R-134a UV Leak Detection Kit (part # 436) which provides UV dye, high-intensity UV light and yellow tinted protective glasses.
