8 Water Temperature Regulation

The thermostat is adjusted to a temperature setting of 125°F or lower when it is
shipped from the factory. Water temperature can be regulated by adjusting the
thermostat to the preferred settings. The preferred starting point is 125°F. There is
a hot water scald potential if the thermostat is set too high.
WARNING: SCALD HAZARD
 Hot water can produce first degree burns within:
—
Less than 5 seconds at 140°F (60°C),
—
Approx. 30 seconds at 130°F (54°C)
—
1.5 to 2 minutes at 125°F (51°C)
During low demand periods when hot water is not being used, a lower thermostat
setting will reduce energy usage and may satisfy your normal hot water
requirements. If hot water use is expected to be more than normal, a higher
thermostat setting may be required to meet the increased demand.
When leaving the premises for extended periods, turn the thermostats to their
lowest settings. This will maintain the water heater at low temperatures with
minimum energy losses and prevent the tank from freezing during cold weather.
Water Temperature Setting
WARNING: SCALD HAZARD
 Households with small children, elderly, impaired or disable
members and anyone with temperature sensitive skin may
require lower temperature settings to reduce the risk of
scald injury.
1. Turn off the power to the water heater.
2. Remove the jacket access panel(s) and insulation exposing the
thermostat(s).
3. Using a small fl at blade screwdriver set the thermostat(s) dial pointer(s) to
the desired temperature.

dishwasher manufacturers.

9 Safety Controls

The water heater is equipped with combination thermostat and temperature
limiting controls (ECO) that are located above the heating element in contact with
the tank surface. If for any reason the water temperature becomes excessively
high, the temperature limiting control (ECO) breaks the power circuit to the heating
element. Once the control opens, it must be reset manually.
WARNING: IMPROPER OPERATION, PERSONAL INJURY
 The cause of the high temperature conditions must be
investigated by a qualifi ed service technician and corrective
actions must be taken before placing the water heater into
service again.
To reset the high limit
1. Water in the tank must to be cooled down.
2. Turn off the power to the water heater.
3. Remove the jacket access panel(s) and insulation. The thermostat
protective cover should not be removed.
4. Press the red RESET button.
5. Replace the insulation and jacket access panel(s) before turning on the
power to the water heater.

10 Seasonal Operation

Vacation/Freezing Temperatures
Drain the piping to the water heater (refer to Page 18) and leave the drain valve
open if the water heater is left idle for 30 days or longer and/or is subjected to
freezing temperatures while shut off .
WARNING: FIRE, EXPLOSION
 Hydrogen gas can be produced in a hot water system
served by this heater that has not been used for a long
period of time (generally two weeks or more). Hydrogen
gas is extremely fl ammable. To reduce the risk of injury
under these conditions, open a hot water faucet for several
minutes before using any electrical appliance connected
to the hot water system. If hydrogen is present, there
will probably be an unusual sound, such as air escaping
through the pipe as water begins to fl ow. There should be no
smoking or open fl ame near the faucet at the time it is open.
