Light Duty Commercial Utility
Energy Saver Electric Water Heater
The Light Duty Utility Electric Models Feature:
■ Fully Automatic Controls—Fast acting surface-mount thermostat for
automatic temperature control. Factory installed sensitive manual reset
energy cut-off for safety to prevent overheating. (Maximum thermostat
setting is 160°F.)

by retarding loss of heat.
■ Water Connections—3/4" NPT factory installed true dielectric fittings
extend water heater life and eases installation. Located on the side for
easier installation.

alternate 3/4" water connection tappings on top.
