General
The TEMPRA 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 ºF (30 ºC)
and 125 ºF (52 ºC). Please set the desired
temperature using the knob on the front
cover. The LED displays the temperature
that the unit will produce in °C. Please use
the conversion table on the unit in order to
obtain degree Fahrenheit. The maximum
temperature is electronically limited to 125 °F
(52 °C).
Recommended is a setting of
108 °F (42 °C) to 116 °F (47 °C).
In case the “Power” light 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.
In case you have questions regarding the way
you plan to use the TEMPRA, 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. You can also e-mail us at
info@stiebel-eltron-usa.com or fax us at USA
413-247-3369.
One TEMPRA can be used for the following
applications.
F
Typical residential installation
F
Typical commercial installation
Mounting the unit
UNIT MUST BE INSTALLED IN A
VERTICAL POSITION WITH THE
WATER FITTINGS POINTING DOWNWARD. DO NOT INSTALL UNIT WHERE
IT WOULD ROUTINELY BE SPLASHED
WITH WATER. ELECTRIC SHOCK MAY
RESULT.
1. Install TEMPRA as close as possible to the
main hot water draw-off points.
2. Install TEMPRA in a frost free area. If frost
may occur, remove unit before freezing
temperatures set in.
3. Leave a minimum of 5“ of clearance on all
sides for servicing.
C
– 6 –
.
D
.
4. Remove the cover
5. Mount unit securely to wall by putting four
screws through mounting holes
Screws and plastic wall anchors for moun-
ting on masonry or wood are provided.
Water connections
1. All plumbing work must comply with national and applicable state and local plumbing
codes.
2. A pressure reducing valve must be installed
if the cold water supply pressure exceeds
150 PSI (10 bar).
3. Make certain that the cold water supply line
has been flushed to remove any scale and
dirt.
4. An isolating valve
of the cold water inlet. This valve allows
the unit to be isolated for maintenance purposes.
5. The cold water connection (inlet) is on the
right side of the unit, and the hot water
connection (outlet) is on the left side of the
unit.
NOTE: EXCESSIVE HEAT FROM
SOLDERING ON COPPER PIPES
NEAR THE TEMPRA MAY CAUSE
DAMAGE.
6. Tankless water heaters such as the TEMPRA
are not required to be equipped with a
Pressure and Temperature Relief Valve
(P&T). If the local inspector will not pass
the installation without a P&T, it should be
installed on the hot water outlet side of the
unit.
7. The TEMPRA is designed for connection
to copper tubing, PEX tubing or a braided
stainless steel hose with a 3/4“ NPT female
tapered thread. If soldering near the unit
is necessary, please direct the flame away
from the housing of the unit in order to
avoid damage.
8. When all plumbing work is completed,
check for leaks and take corrective action
before proceeding.
