Low-Side and High-Side Pressure Monitoring
The dual analog gauges allow technicians to monitor low-side and high-side refrigerant pressure during compatible HVACR service procedures.
Pressure readings can support system inspection and troubleshooting when interpreted together with the refrigerant, equipment specifications and actual operating conditions.
The manifold can also be used as part of applicable evacuation and charging procedures when the gauge set, hoses and service connections are correctly matched to the system.
R22 Refrigerant Service
R22 is one of the refrigerants identified on this manifold gauge set. Before servicing an R22 system, confirm that the selected gauge scale, pressure range, hoses and service connections are suitable for the equipment.
R134A Refrigerant Service
The product is also identified for compatible R134A applications. Technicians should confirm that the manifold configuration and service hoses match the R134A system being serviced.
R404A Refrigerant Service
R404A is included among the refrigerants listed for this manifold gauge product. Confirm the required pressure range and connection configuration for the exact refrigeration equipment before use.
R12 Refrigerant Service
R12 is also identified on this product page. The exact gauge range, hoses and service connection requirements should be confirmed before working on a compatible R12 system.
Double O-Ring Piston Valves
The current product information identifies the manifold with double O-ring piston valves.
These valves form part of the manifold flow-control arrangement used during compatible pressure testing, evacuation and refrigerant charging procedures.
Sight Glass Option
Manifold configurations equipped with a sight glass allow technicians to visually observe liquid movement during applicable service procedures.
The current product information does not state that every configuration includes a sight glass. Confirm this feature for the exact model before ordering.
Gauge Zero Calibration
Check the zero position of the analog gauges before connecting the manifold gauge set to a pressurized system.
According to the current product instructions, if a gauge does not read 0 psi when unpressurized, remove the gauge face and adjust the calibration screw until the pointer returns to 0 psi.
Gauge condition and calibration should be checked before pressure-dependent service work.
