High and Low Water Pressure Controls

These controls interrupt the electrical current to the contactor coil when the

pressure settings are exceeded. The operation and setting of these controls

are described in the manual provided by the control manufacturer. This

manual is included with the water heater Installation and Operating

Instruction manual provided by the manufacturer.

The pressure settings for these controls are adjustable. These controls are

specified for use when the installation has unique pressure requirements that

must be safeguarded. Therefore, before adjusting the pressure values, it is

recommended that you consult the person responsible for the facility that the

water heater is servicing.

The electrical connections are referenced in the Control Circuit Wiring

Diagram and in the pressure control manual provided by the control

manufacturer. Refer to these instructions when servicing the controls.
