3. General

DANGER: WATER TEMPERATURES OVER 125 °F CAN

CAUSE SEVERE BURNS INSTANTLY OR DEATH FROM

SCALDING. A HOT WATER SCALDING POTENTIAL EXISTS

IF THE THERMOSTAT ON THE UNIT IS SET TOO HIGH.

HOUSEHOLDS WITH SMALL CHILDREN, DISABLED OR

ELDERLY PERSONS MAY REQUIRE THAT THE THERMOSTAT

BE SET AT 120 °F OR LOWER TO PREVENT POSSIBLE

INJURY FROM HOT WATER.

The TEMPRA B and TEMPRA Plus units are designed to supply hot water

for a house, apartment or certain commercial applications. Unlike a

conventional storage type water heater the TEMPRA tankless water heater

does not store hot water. Instead, water is heated instantaneously as it

ﬂows through the unit. The TEMPRA offers greater energy efﬁciency than

storage type water heaters due to the absence of stand-by losses and

reduced hot water pipe runs.

The input of heat into the water is controlled electronically. The TEMPRA

will deliver any water temperature between 86 °F (30 °C) and 140 °F (60 °C).

Please set the desired temperature using the knob on the front cover. The

TEMPRA Plus Temperature adjustment knob can be set to: OFF, 86...140 °F

(30...60 °C).

The TEMPRA B has a °F and a °C scale. The output temperature of the

TEMPRA Plus is shown in the digital display in °F or °C units. (°F or °C units

can be selected during installation, factory setting: °F). The maximum

temperature is electronically limited to 140 °F (60 °C).

For reasons of appliance efﬁciency and durability (scaling), the

optimum temperature setting lies between 86 °F (30 °C) and

120 °F (50 °C).

The outlet temperature of the TEMPRA Plus can be limited (see "Initial

settings").

TEMPRA B units:

In case the "Power” LED is ﬂashing while the unit operates, the water

ﬂow rate exceeds the heating capacity of the unit. Reduce the hot water

ﬂow rate in order to let the unit achieve the set point temperature.
