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 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 TEMPRAS tankless water heater does
not store hot water. Instead, water is heated
instantaneously as it fl ows through the unit.
The TEMPRAS offers greater energy effi ciency
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 TEMPRAS 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 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).
Recommended is a setting of
108 °F (42 °C) to 116 °F (47 °C).
The outlet temperature of the TEMPRA Plus
can be limited to 109 °F (43 °C).
In case the "Power" LED is fl ashing while the
unit operates, the water fl ow rate exceeds the
heating capacity of the unit. Reduce the hot
water fl ow rate in order to let the unit achieve
the set point temperature.
In case you have questions regarding the way
you plan to use the TEMPRAS, please call our
technical service line at 800-582-8423 (USA
and Canada). For service outside the U.S. and
Canada, please call us at USA 413-247-3380.
