Thermostat Adjustment
The temperature of the water can be changed by adjusting the thermostat(s).
Before any work is done on the water heater, disconnect all power to the
water heater by opening the switch at the main electrical circuit breaker or
fuse box. Remove the access panels or front panel on table tops, fold the
insulation outward away from the controls. Set the thermostat(s) to the
desired water temperature using a screwdriver to move the thermostat dial.
The thermostat has been factory preset to approximately 120°F
(49°C).
Rotate the temperature dial clockwise to increase water temperature.
Replace the insulation making sure that the controls are well covered and
that the plastic terminal shield has not been displaced; replace the access
panel. The water heater is now ready for operation and the main switch can
be closed.

CAUTION
Before adjusting thermostat(s), turn off power supply to the water heater.
Hotter water increases the risk of scald injury. Scalding may occur within
five (5) seconds at a temperature setting of 140°F
(60°C).
To protect
against hot water injury, install an ASSE approved mixing valve in the water
system. This valve will reduce point of discharge water temperatures by
mixing cold and hot water in branch water lines. A licensed plumbing
professional or local plumbing authority should be consulted.
Note: This water heater is equipped with an energy cut out device to
prevent overheating. Should overheating occur, turn off the electrical supply
to the water heater and contact a qualified service technician.

MAINTENANCE
Shut off the electric power whenever the water supply to the water heater is
off. Shut off the electric power and water supply, drain the water heater
completely to prevent freezing whenever the building is left unoccupied
during the cold weather months. In order to insure efficient operation and
long tank life, drain the water heater at least once a month through the drain
valve until the water runs clear. Failure to do this may result in noisy
operation and lime and sediment buildup in the bottom of the tank. Check
the temperature-pressure relief valve to insure that the valve has not
become encrusted with lime. Lift the lever at the top of the valve several
times until the valve seats properly without leaking and operates freely.
The following maintenance should be performed by a qualified service
technician at the minimum periodic intervals suggested below. In some
installations, the maintenance interval may be more frequent depending on
the amount of use and the operating conditions of the water heater. Regular
inspection and maintenance of the water heater will help to insure safe and
reliable operation.
1. Annually, check the operation of the thermostat(s).
2. Bi-annually, check the seal around the heating elements for leaks. If there
is any sign of leaking, disconnect the power supply to the water heater
and contact the plumbing professional that installed this water heater or a
qualified service technician.
IMPORTANT
The water heater should be inspected at a minimum of annually by a
qualified service technician for damaged components.
DO NOT
operate
this water heater if any part is found damaged.
WARNING
When lifting lever of temperature-pressure relief valve, hot water will be
released under pressure. Be certain that any released water does not
result in bodily injury or property damage. The magnesium anode rod
should be inspected periodically and replaced when necessary to prolong
tank life.
