Product Overview:
The Swimables SW41060 MasterTemp MaxETherm style pressure switch is an essential safety and functional replacement part for Pentair MasterTemp, StaRite MaxETherm, and ETI 400 pool and spa heaters. Operating under OEM part 420010060S, this switch monitors water pressure within the heaters plumbing circuit. It ensures proper water flow is present before allowing the burner to activate, thereby safeguarding against dryfiring and potential heat exchanger damage.
Constructed with highquality components, this pressure switch attaches directly to the manifold and responds reliably to pressure variations. Should water pressure fall below required thresholds, the switch deactivates the ignition sequence, helping prevent overheating scenarios and equipment failure. At approximately 0.11 lb and compact in size, it’s easy to handle and install without specialized tools, making it a practical replacement item.
Ideal for pool owners and service technicians, the SW41060 reinstates safe and efficient heater operation, promoting longevity of the heating system. Whether addressing a fault code or performing preventative maintenance, this switch remains a vital component for reliable pool and spa heating.
