Bard 8406-067 Pressure Switch Manual Reset High Pressure

Product Description

The BARD 8406-067 is a manual reset, high-pressure switch designed for use in HVAC systems. This safety control monitors refrigerant or system pressure and opens the circuit when pressure exceeds a set threshold, shutting down equipment to prevent damage. Unlike automatic-reset switches, the 8406-067 requires a deliberate manual reset after a trip event, which helps prevent equipment from cycling back on before the root cause of the fault has been identified and corrected. It is typically installed by licensed HVAC technicians as part of a refrigeration circuit or equipment safety chain.

This high-pressure switch is used in commercial and residential HVAC applications where manual reset functionality is required by equipment design or local code. It is suited for installation in systems where automatic restart after a high-pressure trip could cause equipment damage or safety hazards. Technicians installing this switch should verify the pressure rating and terminal configuration match the system requirements before installation.

Key Features

• Manual reset operation requires deliberate technician intervention after a high-pressure trip
• High-pressure switch function protects refrigerant circuits and associated equipment from overpressure conditions
• Compact and lightweight at 0.29 pounds for easy integration into control panels or equipment cabinets
• Designed for HVAC system applications where safety lockout is required on overpressure events

Compatibility

Designed as an OEM-style replacement high-pressure switch for HVAC systems requiring a manual reset, high-pressure safety control.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect all power to the unit and recover refrigerant per EPA Section 608 guidelines before accessing the refrigerant circuit. Verify the switch pressure rating matches system operating parameters before installation. After resolving the condition that caused the initial trip, manually reset the switch before returning the system to service.
