FIG. 24 Electronic Low Water Cut-off Control

This water heater may be equipped with an optional electronic low water cut-off installed at the factory. This low water cut-off device uses a water level sensing probe located above the heating element installed in the highest point in the storage tank. If the internal water level drops below this point, the low water cut-off will shut down operation of the heating elements. An electronic type low water cut-off is available as a factory supplied option on all models. The optional electronic low water cut-off has an LED located on the main circuit board. This LED will be illuminated and the control circuit will be completed between the common and normally open contacts on the circuit board when the sensing probe is below the water level in the storage tank. An optional manual reset function and test button is available on the electronic low water cut-off. The operation of a low water cut- off should be inspected every six months.

FIG. 25 Low Water Pressure Switch

LOW WATER PRESSURE SWITCH

(Optional)

A low water pressure switch is available as an option on this water heater. A water pressure switch is used to monitor the water pressure in the water heater storage tank. If the water pressure drops below an adjustable set point, the control circuit is opened and operation of the water heater is shut down. The low water pressure switch may be specified with either a auto-reset function or a manual reset function on low water pressure.

HIGH WATER PRESSURE SWITCH

(Optional)

FIG. 26 High Water Pressure Switch

A high water pressure switch is available as an option on this water heater. A water pressure switch is used to monitor the water pressure in the water heater storage tank. If the water pressure rises above an adjustable set point, the control circuit is opened and operation of the water heater is shut down. The low water pressure switch may be specified with either a auto-reset function or a manual reset function on high water pressure.

MANUAL LIMITING SWITCHES (Optional)

As an option, a switch or multiple switches may be provided to interrupt the 120 VAC control circuit feed to the contactor coil or coils from the immersion heating thermostat(s). This switch may be used to manually turn off a portion of the heating element input. This feature may be used to reduce
