Installation & Compatibility Notes

Before installing, disconnect power to the heater and allow it to cool. Remove the old pressure switch and clean the mounting surface on the header. Install the new 006737F switch, ensuring proper mounting orientation and full threading engagement. Restore heater power and monitor operation; verify the heater cycles normally and shows no error codes related to flow or pressure. If the heater still indicates low pressure or flow, check plumbing and pump components in addition to the switch.

Maintenance Tips

Inspect the switch annually for corrosion, damaged diaphragm or faulty contacts—replace if any issue is found.
Ensure the plumbing system provides consistent circulation and that no air pockets or blockages affect pressure measurement.
Having a replacement switch in stock helps service professionals reduce downtime during heater repair calls.

Why Choose This Switch?

Replacing the pressure switch with the correct OEM part ensures your Raypak heater functions reliably, safely and in line with manufacturer requirements. The Raypak 006737F offers peace of mind, professional-grade compatibility and service-ready performance.
