Raypak 062237B Pressure Switch

The Raypak 062237B Pressure Switch is a critical safety component designed for precise water flow monitoring in Raypak pool heaters, specifically the 185A, 265A, 335A, and 405A models. This SPST (Single Pole Single Throw) switch features a robust brass compression connection and is engineered to protect the heat exchanger by ensuring the burner only fires when adequate water pressure is detected. Rated for a factory setting of approximately 1.75 PSI, this genuine OEM replacement part prevents dry firing and overheating, common causes of premature equipment failure. The unit comes complete with terminal connectors and a durable brass fitting to ensure a leak-proof seal during installation. Technicians frequently utilize the Raypak 062237B to resolve "Water Sw Open" or "PRS" fault codes on digital displays. Its heavy-duty construction is built to withstand the corrosive chemical environments typically found in pool and spa applications, maintaining system integrity across various Raypak atmospheric heater series.

Key Benefits

• Optimized Compatibility: Fits Raypak heater models 185A, 265A, 335A, and 405A, ensuring a perfect mechanical match and electrical interface.
• System Protection: Acts as a primary safety interlock to prevent the heater from operating under low-flow or no-flow conditions.
• Durable Construction: Features a brass compression connection for superior corrosion resistance and long-term reliability in outdoor environments.
• Direct OEM Replacement: Replaces factory part numbers 062237B and RAY-151-3584, maintaining the original engineering specifications of the heating system.

Common Questions

Where is the Raypak 062237B pressure switch located?
On most compatible models, the switch is mounted on the header (inlet/outlet manifold) to directly monitor the water pressure entering the heat exchanger.

What causes a "Water Sw Open" or "PRS" error code?
These codes often indicate that the pressure switch has detected insufficient water flow. This can be caused by a dirty filter, closed valves, a failing pump, or a faulty 062237B pressure switch that no longer closes the circuit.

Can I adjust the PSI setting on this switch?
While the switch is factory-set for deck-level installations, it can be adjusted for heaters located above or below the pool water level. However, this should only be performed by a qualified technician using a multimeter to confirm the circuit closes at the correct flow rate.
