Antunes Controls 804111707 Pressure Switch

The Antunes Controls 804111707 is a high-performance HLGP-A manual reset pressure switch designed for precision monitoring in commercial HVACR and process heating applications. This dual-purpose unit features a high-limit range of 5 to 28 inches W.C. and a low-limit range of 6 to 24 inches W.C., providing critical protection against over-pressure or loss of pressure conditions. Built for industrial durability, the 804111707 pressure switch incorporates a SPDT contact configuration, ensuring reliable signal transmission to safety circuits or building management systems. As a gas pressure safety switch, it is compatible with natural gas, propane, and air, making it a versatile component for burner manifolds and commercial ovens. The manual reset feature is essential for systems requiring technician intervention following a trip, preventing automated restarts in unsafe conditions. For contractors, the 1/4" NPT connection and robust housing ensure straightforward installation and long-term stability in high-demand environments.

• Dual-Function Monitoring: Combines high and low pressure sensing within a single HLGP-A model, reducing cabinet footprint and installation labor.
• Reliable Manual Reset: Ensures system lockout until a diagnosis is performed, meeting strict safety protocols for industrial gas pressure regulators and burners.
• Precise Setpoint Adjustment: Features an accessible adjustment dial for field-tuning water column pressure settings to match specific equipment requirements.
• Durable Construction: Engineered to withstand the rigors of commercial mechanical rooms and industrial kitchen environments.

How do I adjust the trip points on the Antunes 804111707?
Adjustments are made via the internal scale. Use a calibrated manometer to verify the inches W.C. setpoints during commissioning to ensure the manual reset pressure switch trips at the specified parameters.

What media is this pressure switch compatible with?
This Antunes gas pressure switch is rated for use with air, natural gas, and LP gas (propane) in non-corrosive environments.

Can this replace an automatic reset HLGP model?
No, the 804111707 is a manual reset unit. Replacing an auto-reset switch with a manual reset one may be required for code compliance in certain furnace or boiler applications, but always verify the original sequence of operations.
