Key Features

• 4.3” Colour Touchscreen LCD: Intuitive resistive touchscreen for easy navigation, compatible with gloved hands or non-scratching styluses, with clear digital and analogue displays of pressure and temperature.
• Premium Vacuum Sensor: Built-in sensor with 1-micron accuracy (20,000 to 1 micron range), eliminating the need for external vacuum gauges.
• Advanced Diagnostics: Automatically calculates superheat and subcooling for over 60 refrigerants (e.g., R134a, R410A, R32, R1234yf). Displays pressure (psi, bar, MPa, kg/cm², kPa), temperature (°F or °C), and vacuum (micron, mBar, kPa, Pa, Torr, mTorr, mmHg).
• Bluetooth® Connectivity: Wirelessly monitor system performance via the Mastercool Connect app, with data logging for up to 36 hours, downloadable to spreadsheets for detailed analysis.
• Pressure Leak Test Function: Displays delta for vacuum and positive pressure tests, with timers and alarms to enhance diagnostic accuracy.
• Class 1.0 Gauge Accuracy: ±1 psi or 1% of reading (whichever is greater), with a proof pressure of 1000 psi (70 bar) for reliable performance under high-pressure conditions.
• Calibration Features: Simple pressure, temperature, and vacuum sensor calibration for ongoing accuracy, with a recommended pressure calibration near 300 PSI.
• Auto-Off and Sleep Mode: Conserves Li-Ion battery life (30-36 hours normal use, 25-30 hours with Bluetooth) with 30-minute auto-off and 4-minute sleep mode.
• ESD Protection: Designed to mitigate Electric Static Discharge, ensuring stable operation and display reliability in demanding environments.

Included Components

The Mastercool 99946-BT package includes high-quality components for immediate use:

• 60” High-Pressure Hoses (RYB): Three 152 cm hoses with 1/4” SAE standard fittings, 600 PSI working pressure, 3000 PSI burst pressure, and knurled brass nuts (Part #85211-R, 85212-R, 99923-YK).
• 3/8” SAE Black Vacuum Hose: Durable hose for efficient vacuum operations (Part #99923-BK).
• Premium Type-K Thermocouple Clamp: 3 ft (1 m) ergonomic clamp for precise temperature readings (Part #52036).
• USB Type-C Charging Cable: For recharging the Li-Ion battery (Part #99923-CPORT).
• 4-Piece Sight Glass Assembly: Enhances visibility during diagnostics (Part #99923-SG).
• Rubber Boot (Less Charging Plug): Protective cover for durability (Part #99923-RB-1).
• Plastic Carrying Case: For secure storage and transport of all components.

Operational Advantages

The 4-way configuration of the Mastercool 99946-BT allows technicians to vacuum and charge A/C systems without changing hose connections, significantly reducing downtime. The manifold’s left-centre fitting and black valve connect to recovery systems and vacuum pumps. At the same time, the right-centre fitting supports refrigerant sources, enabling seamless transitions between vacuuming and charging without purging hoses. The built-in vacuum sensor and K-type thermocouple clamps (left port for superheat, right for subcool) provide accurate real-time calculations, displayed on the touchscreen or via the app. The manifold supports recovery, vacuum, and charging processes with clear instructions for connecting to HVAC units, recovery machines, or vacuum pumps.

Maintenance and Spare Parts

The Spartan manifold is designed for long-term reliability, with repairable components listed in the official parts breakdown (Part #99943-8T-PAMTS). Key spare parts include:

• Pressure Sensor (Part #99923-002)
• Vacuum Sensor (Part #99923-003B-1)
• LCD Assembly (Part #99923-005-43B)
• Keypad (Part #99923-008)
• Optional 10 ft (3 m) K-Type Probe (Part #52108)

To maintain the vacuum sensor, use Mastercool ACC Flash Solvent (Part #91049-32) to clean contaminants, followed by vacuum pump drying. Avoid complete battery discharge to maximise lifespan, and store the manifold in a dry place to prevent moisture damage.

Why Choose the Mastercool 99946-BT?

Built for the rigours of professional HVAC work, the Mastercool 99946-BT combines cutting-edge technology with practical design.

Safety and Usage Notes

Wear safety glasses and gloves when operating. If refrigerant contacts the eyes, flush with water and seek medical attention immediately. Charge the manifold overnight before first use, and ensure the battery indicator is not red to maintain sensor accuracy. Avoid placing the manifold on top of A/C systems to prevent incorrect temperature readings.
