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).
