Fluids under pressure may cause injury to personnel or damage to equipment when
released. Be sure to shut off all incoming and outgoing water shutoff valves. Carefully
decrease all trapped pressures to zero before performing maintenance.
•
Before attempting to perform any maintenance on the unit, shut off all electrical power to
the unit from an exterior switch.
•
Electrical voltages up to 120 VAC may be used in this equipment; therefore, the front panel
door on the unit’s power box must be closed at all times, except during maintenance and
servicing.
•
A three-pole switch must be installed on the electrical supply line of the unit. The switch
must be installed in an easily accessible position to quickly and safely disconnect electrical
service. Do not affix switch to any part of the water heater itself.
