VALUE Manifold Gauge Set

VALUE Manifold Gauge Set for Professional AC Technicians

Busy technicians need gauges they can trust on every job, from a home split unit in the morning to a supermarket cold room in the afternoon. The VALUE manifold gauge set is a favourite with AC and refrigeration professionals for exactly this reason. At Wisdo Merchants, we supply it to HVAC contractors, refrigeration engineers and workshops across Nairobi and Kenya.

VALUE is an established manufacturer of tools for the HVAC trade, including vacuum pumps, recovery machines and gauges. This dual manifold set combines a low-side and a high-side gauge on one valve body. As a result, technicians can charge, evacuate and diagnose systems quickly with a single, well-built tool that shows how the vapour-compression cycle is performing.

Features and Benefits of the VALUE Manifold Gauge Set

• Large, easy-read dials. Clear, colour-coded gauge faces make readings quick, even in dim plant rooms.
• Refrigerant temperature scales. The dials show saturation temperatures for common refrigerants, so there’s less need for charts.
• Sight glass. A sight glass on the manifold lets you watch refrigerant flow while charging.
• Robust construction. A metal manifold body with brass connections stands up to daily site use.
• Complete kit. It comes with red, blue and yellow charging hoses in a fitted carry case.

For contractors, this means one dependable tool for most of the systems they service. Meanwhile, clients benefit from faster, more accurate repairs.

Applications of the VALUE Manifold Gauge Set and How to Use It

• Charging and topping up split ACs, VRF units, fridges and freezers
• Evacuating systems with a vacuum pump before charging
• Nitrogen pressure tests on new pipework
• Fault diagnosis on AC and refrigeration systems
• Commissioning new installations

Charging a New Split Unit

Picture an installer finishing a new office split AC. First, they connect the gauges and pressure-test the pipework with nitrogen. Next, they pull a deep vacuum through the manifold to remove air and moisture. After that, they connect the refrigerant cylinder to the yellow hose and charge the system by weight, watching the sight glass and gauges. Finally, they check the running pressures against the saturation temperatures on the dial. For the gas itself, choose the refrigerant on the unit’s nameplate, such as our low-GWP HFC-32 for inverter units.

Check the Refrigerant Before You Start

Newer refrigerants such as R410A and R32 run at much higher pressures than R22. Therefore, always check that the gauge’s pressure range and scales cover the gas you are working with. If a system keeps losing gas, the gauges will show it; to trace the leak, try our UV-dye leak sealer.

Safety and Handling

• Wear safety glasses and gloves. Escaping liquid refrigerant can cause frostbite.
• Respect pressure ratings. Never connect the gauges to a system above their rated range.
• Inspect hoses and seals. Replace damaged hoses and worn gaskets promptly.
• Open valves slowly. This protects the gauges and prevents sudden refrigerant release.
• Never vent refrigerant. Recover it with proper equipment.
• Store in the case. Keep the gauges protected from knocks, dust and moisture.

Frequently Asked Questions

What do the blue and red gauges show?

The blue gauge reads the low (suction) side and the red gauge reads the high (discharge) side of the system.

What is the yellow hose for?

It’s the service hose. It connects to the refrigerant cylinder, vacuum pump or recovery machine.

What does the sight glass do?

It lets you see refrigerant flowing through the manifold, which helps when charging liquid.

Which refrigerants can I use it with?

Check the scales printed on the gauge faces, or ask our team before buying. High-pressure gases such as R410A and R32 need gauges rated for them.
