OPTIONS

The following optional features may be included in your water heater. Reference included drawing

specific to your heater for further details.

Low Water Cut-Off

Used as a safety device, the electronic low water cut-off is

used to detect a low water situation and disengage the

operating coils in the magnetic contactor(s). Once the

condition is remedied, the low water cut-off switch is

automatically reset.

Fused Low Voltage Transformer

A fused low voltage transformer may be supplied. This option

is used only in 480-volt systems with low water cut-offs to step

down the voltage to 240-volt for safety when working with

control circuits.

Dial Temperature and Pressure Gauge

A combination temperature (70° - 250° F) and pressure (0

– 200 psi) gauge with 2½-inch dial may be supplied for

in-line installation (shipped loose).
