Honeywell SP970A Installation Instructions

Ensure the regulator is mounted in a vertical position with adequate clearance for maintenance. Use the appropriate fittings and sealants to prevent leaks. Follow the installation instructions provided by Honeywell to ensure safety and compliance.
To calibrate, connect a pressure gauge to the output and adjust the set screw until the desired output pressure is achieved. Verify the accuracy using a calibrated reference gauge.
Check for blockages or leaks in the system. Ensure that the regulator is properly calibrated and that the input pressure is stable. Inspect internal components for wear or damage.
Perform visual inspections monthly, check for leaks and wear every three months, and conduct a full functional test annually. Replace any worn components as needed.
Shut off the system pressure and carefully disassemble the regulator. Clean components with a mild detergent and water. Dry thoroughly before reassembly. Avoid using harsh chemicals that can damage the regulator.
Check for leaks in fittings and connections. Ensure the regulator is properly calibrated. Inspect internal components for signs of wear or damage and replace if necessary.
The SP970A is not recommended for use with corrosive gases unless specifically designed for such applications. Consult Honeywell for compatible models and materials.
The SP970A Regulator operates efficiently within a temperature range of -40°C to 60°C (-40°F to 140°F). Ensure the environment stays within these limits for optimal performance.
Relieve system pressure and disassemble the regulator. Remove the old diaphragm and install a new one, ensuring proper alignment. Reassemble the regulator and test for leaks and functionality.
Common causes include improper installation, lack of maintenance, contamination, and exceeding design limits. Regular inspections and adherence to Honeywell guidelines can prevent failures.
