IMPORTANT SAFETY INFORMATION
Water Supply Safety
DANGERS:
• WATER TEMPERATURE
SETTINGS – Safety and energy
conservation are factors to be
considered when selecting the
water temperature setting of a
water heater’s remote control.
Water temperatures above 125°F
(52°C) can cause death or severe
burns from scalding. Be sure to
read and follow the warnings
outlined on the pictured label.
• There is a hot water scald potential
if the water temperature is set
too high. Households with small
children, the disabled, or elderly
persons may require a 120°F
(49°C) or lower temperature setting
to prevent contact with “HOT”
water.
• Before manually operating the relief
valve, make certain no one will be
exposed to the danger of the hot
water released by the valve. The
water may be hot enough to create
a scald hazard. The water should
be released into a suitable drain to
prevent injury or property damage.
• Failure to perform the recom-

can cause severe burns instantly or
death from scalds.
Children, disabled and elderly are
at highest risk of being scalded.
See instruction manual before
setting temperature at water
heater.
Feel water before bathing or
showering.
Temperature limiting valves are
available, see manual.

CAUTIONS:
• This water heater must only be used
with the following water supply system
conditions:
– With clean, potable water free of
corrosive chemicals, sand, dirt, or
other contaminants.
– With inlet water temperatures above
32°F (0°C), but not exceeding 120°F
(49°C).
– DO NOT reverse the hot and cold
water connections. The water heater
will not operate.
• Even when drained properly, a small
amount of water will remain in the water
heater. In cold weather conditions, this
water can freeze. If this happens, allow the
defrost protection on the heater at least
30 minutes to melt the frozen water or the
water heater may not work properly.
NOTICE:
The factory setting
allows operating temperatures between
100°F (38°C) and 120°F (49°C).
Temperatures of 85°F (29°C) and up
to 140°F (60°C) can be achieved with
the MAIN (UMC-117) remote control.
Temperatures of 85°F (29°C) can be
achieved with the Bath (USC-117 or
USC2-117) remote control. Only qualified
service personnel should perform this
adjustment. Only factory-authorized
remote control(s) should be used.
• mended Routine Preventive Maintenance can harm
the proper operation of this water heater, which can
cause carbon monoxide dangers, excessive hot
water temperatures, and other potentially hazardous
conditions.
WARNINGS:
• IMPORTANT: Do not apply heat to the HOT or
COLD water connections. If sweat connections are
used, sweat tubing to adapter before fitting adapter
to the water connections on heater. Any heat
applied to the water supply fittings will permanently
damage the internal components of the water
heater.
• In case the pipe insulation is not rated for the
appropriate weather conditions, install electric
heat tracing or equivalent to prevent freezing of
the pipes. Do not insulate or block the drain valve
on the hot outlet fitting. If the pipes are allowed
to freeze, the water heater and the pipes may
malfunction or leak due to freezing water.
• Failure to drain the water heater as described on
page 20 can cause serious personal injuries from
scalding and/or damage the water heater.
