Product Overview

The Raypak 006737F Direct Mount Pressure Switch is a genuine OEM replacement water-pressure safety switch designed for compatible Raypak gas pool and spa heaters. Rated at 1.75 PSI, the switch mounts directly to the heater inlet/outlet header and monitors water pressure to help verify adequate circulation before heater operation.

When sufficient water pressure is present, the switch closes the heater safety circuit and allows the ignition sequence to continue. If adequate pressure or circulation is not detected, the switch helps prevent heater operation, protecting the heat exchanger and other components from potential damage caused by insufficient water flow.

Specifications

Installation Information

The 006737F mounts directly into the compatible heater inlet/outlet header.

Before servicing:

• Disconnect electrical power to the heater
• Shut off the gas supply
• Turn off the circulation pump
• Allow the heater to cool completely
• Relieve water pressure as required

Disconnect the pressure-switch wires before removing the existing switch. Inspect the header threads, wiring terminals, connectors, and surrounding components for corrosion or damage before installing the replacement.

Installation and heater diagnosis should be performed by a qualified pool-heater service professional.
