Instruction for changing the setting to 140ºF (60ºC) or
185ºF (85ºC):
WARNING: Improper adjustment, alternation, service or maintenance can cause property
damage, personal injury, or death.
Maximum Temperature Adjustment by the Main Remote Control (UMC-117)
Required adjustment for up to 140ºF (60ºC) water temperature setting for Residential product or 185ºF (85ºC)
water temperature setting for Commercial version.
Note: Commercial version requires the adjustment by the commercial conversion kit.
WARNING: Changing this setting is done at your risk.
WARNING: Water Temperature over 125ºF (52ºC) can cause severe burns instantly or death from scalds.
Children, disabled and elderly persons are at highest risk of being scalded. See the Instruction Manual before
setting the temperature on the remote control. FEEL WATER BEFORE BATHING or SHOWERING. DO NOT
leave a child in the bath unsupervised.
Danger: Hotter water increases the potential for Hot Water SCALDS.
Notice: For safety reasons the BATH Remote Control(s) cannot be adjusted to temperature above 120ºF (49ºC).
Note: We recommend that you install the thermostatically controlled tub and shower valve & tempering valve
for your safety.
DO NOT execute the following adjustment if the setting of up to 140ºF (60ºC) or 185ºF (85ºC) is not required.
Follow the instruction below if it is determined that a setting of up to 140º (60ºC) or 185ºF (85ºC) is required.
(1) Turn on the remote control (UMC-117). Turn off the gas and water shutoff valves.
(2) Press the UP arrow temperature adjustment button on the remote control for several times and set the temperature
at 120ºF (49ºC).
(3) Press and hold the UP button on remote control for more than 5 seconds. Number (120) on the display of the re-
mote control will begin to blink.
(4) While the number is blinking, push the UP arrow temperature adjustment button and the DOWN arrow temperature
adjustment button at the same time. The display of the remote control will show "140".
(5) Push the UP or DOWN button to set desired temperature.
(6) Turn on the gas and water shutoff valves.
(7) Check and ensure safe operation and performance of the water heater.
