Key Features

• Anti-Flutter Gauges: 3.5-inch silicone-dampened gauges smooth out needle movement for precise pressure readings, enhancing diagnostic reliability.
• Easy-to-Read Dials: Large gauge faces display measurements in Bar, PSI, °F, and °C, with clear temperature scales for quick reference under all lighting conditions.
• Recalibratable Accuracy: Gauges can be easily recalibrated to maintain long-term precision, reducing the need for costly replacements.
• Free-Floating Piston Valves: Piston-type valves minimise O-ring wear, ensuring smooth operation and extended durability.
• Extra-Large Sight Glass: Allows quick visual checks of refrigerant flow, simplifying system diagnostics and ensuring efficient servicing.
• Heavy-Duty Aluminium Manifold Block: Assembled with three 12 mm-F fittings per SAE J2888, constructed from extruded aluminium for exceptional strength and long-lasting performance.
• Industry-Compliant Hoses: Includes three 72-inch nylon barrier hoses (red, blue, and yellow) meeting SAE J2888, EPA, SAE, and UL standards for leak-free performance with R1234yf refrigerants:
  • Red and blue hoses feature 12mm-M fittings on both sides, compliant with SAE J2888.
  • Yellow hose has a 12mm fitting on one side and 1/2 x 16 LH ACME on the other, meeting SAE J2844.
• R1234yf Couplers: High and low-side couplers with extended disconnect protection sleeves comply with SAE J639 and J2888, ensuring secure, leak-proof connections during refrigerant recovery and charging.
• Ergonomic Design: Easy-grip, front-facing knobs provide precise control, while a built-in hose organiser and robust clamshell case ensure neat storage and portability.

Applications

Perfect for diagnosing and servicing automotive air conditioning systems, the Mastercool 83272 is suited for:

• Identifying low refrigerant levels (low side and high side pressures are low).
• Detecting system blockages, such as in expansion valves or orifice tubes (low side pressure low, high side pressure high).
• Troubleshooting compressor faults, indicated by high low-side pressure, low high-side pressure, and a vibrating gauge needle (faulty reed valves).
• Diagnosing overcharged systems (high low-side and high-side pressures).

How to Use

System Diagnosis:

1. Ensure service ports are clean and free of metal shavings.
2. Verify both manifold valves are fully closed.
3. Connect the blue coupler to the compressor suction service valve (low side).
4. Connect the red coupler to the compressor discharge service valve (high side).
5. Start the vehicle, set A/C to HIGH, and fan to HIGH.
6. Observe gauge readings and refer to your automotive manual for diagnosis (e.g., low pressure may indicate low charge, blockages, or compressor issues).

Charging Refrigerant:

1. Ensure both manifold valves are fully closed.
2. Turn on the vehicle and A/C system to aid refrigerant charging.
3. Connect a vacuum pump adapter to a vacuum pump (not included).
4. Attach the yellow hose to the manifold’s centre port and its shut-off valve end to the vacuum pump. Remove air from the hose and manifold.
5. Disconnect the yellow hose from the vacuum pump and connect it to an R1234yf gas supply, following the refrigerant manufacturer’s instructions.
6. Slowly open the low-side valve until pressure reaches 42 PSI. Do not exceed 42 PSI to avoid compressor damage.
7. Close the low-side valve when charging is complete.

Warning: Always wear safety goggles and avoid contact with refrigerant to prevent injury.
