OUTER SHELL, INSULATION, AND SUPPORTS
The tank is encapsulated in 2-inches of high-density fiberglass insulation. The protective shell is
constructed of galvaneel and is coated with a durable silver hammertone finish. NSF approved
adjustable plastic legs are provided for support.
FUSED LOW VOLTAGE TRANSFORMER
A fused low voltage transformer is supplied with all models rated
for 480-volts. This component is used to step down the 480-volt
power supply to 240-volts for safety when working with control
circuits. As an option, a transformer may be installed on any unit
to step down the voltage to 120-volts.
ON/OFF SWITCH
An illuminated on/off switch is provided for positive verification heater status.
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.
Stainless Steel Outer Jacket
An optional stainless steel outer jacket may replace the standard galvaneel jacket.
