Water Temperature Setting continued…
Set Temperature Memory:
1. This model can memorize and save the last set temperature on the remote control with “priority”.
2. If no remote control has “priority”, the set temperature of the unit will be the same as the set
temperature of the remote control which starts the water heater.
• This water heater contains an electronically
controlled thermostat. From the factory, the
temperature range is between 90°F and 140°F.
• The remote control is factory preset to 110°F.
• To turn the remote control ON or OFF, press
the POWER button for more than 3 seconds.
• To adjust the temperature to a required
setting, in“priority” mode, press the UP or
DOWN temperature button. Press and hold UP
or DOWN to raise or lower the temperature
continuously.
• When the unit is in use, the set temperature
can increase to 122°F, but there is no limit
to temperature decrease. To increase the
temperature more than 122°F, the water will
need to be shut o rst.
NOTICE: If inlet water temperature is high,
and set temperature is low, the actual
temperature might be higher than the set
temperature, and vice versa.
• The display will read the set temperature if the
water heater is not in use or there is no water ow.
If the water heater is in use or has water ow, the
display will read the actual temperature. To view
the set temperature in this condition, press UP or
DOWN and the set temperature will ash for 3
seconds.
• The hottest temperature water will be at the hot
water faucet closest to the water heater
• Always remember to test the water temperature
with your hand before use and remember that
hotter water increases the risk of scald injury.
• Always supervise young children or others who are
incapacitated.

ood or physical damage, turn o the manual gas
shut-o valve(s), and do not operate the water
heater again until it has been checked by qualied
personnel.

contaminant levels allowed, based on the
EPA National Secondary Drinking Water
Regulations (40 CFR Part 143.3).

contaminated in any way, discontinue use of
the water heater and contact an authorized
