4. General
I The Tempra B and Tempra Plus units are designed to supply hot
i water for a house, apartment or certain commercial applications.
Unlike a conventional storage type water heater the Tempra tank -
less 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 140 IF (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 OC).
The Tempra B has a IF and a *C scale. The output temperature of
the Tempra Plus is shown in the digital display in IF or 'C units.
(OF or *C units can be selected during installation, factory setting:
IF). The maximum temperature is electronically limited to 140 IF
(60 OC).
WWW.STIES EL- E LTRO N - U SA.CO M TEMPRA & TEMPRA PLUS 13
For reasons of appliance efficiency and durability (scaling), the
optimum temperature setting lies between 86 OF (30 OC) and
120 OF (50 OC).
The outlet temperature of the Tempra Plus can be limited (see
"Initial settings").

1. Install Tempra in a frost free area. If frost might occur, re-
move unit before freezing temperatures set in.
2. Leave a minimum of 5" of clearance on all sides for servicing.
3. Remove the cover screw with a #2 Pozi-drive screwdriver and

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. The Tempra unit has a built in filter screen (9 that should be
cleaned from time to time. Clean screen and put the screen
and the washer 6 back into their original position.
5. 1 he cold water connection (inlet) is on the right side of the
unit, and the hot water connection (outlet) is on the left side
ofthe unit.

6. The Tempra on the hot side is designed for connection to
copper
tubing, PEX tubing or a braided stainless steel hose with a
3/4" NPT female tapered thread.
The plumbing on the cold water inlet side needs to be such
that
it can easily be removed to allow access to the inlet filter
screen.
The easiest way to achieve this is to us a stainless steel
braided hose connector.
If soldering near the unit is necessary, please direct the
flame away from the housing of the unit in order to avoid
damage.

Please refer to the technical data table for the correct wire and
circuit breakersize. In all cases, makesurethatthe unit is properly
grounded.
1. Cut the electrical connection cable to length and strip.
15" (380MM)
The wire must be fed through the knock -outs located between
the hot and cold water connections (See 8.1, "Circuit Layout",
pg. 6). The "live" wires must be connected to the slots on the
terminal block marked Ll and L2. The ground wire must be con-
nected to slot marked with the ground symbol (See 13.5. "Wiring
Diagrams", pg. 13).

- (9 Activate anti -scalding protection function
On the Tempra Plus, an anti -scalding protection function can be
activated by two different methods.
1. Limit the outlet temperature to the fixed temperature of
109 OF (43 OC).
- Insert the coding plug into position Tred (reduced
temperature).
2. Select a specific outlet temperature
- Switch the appliance 'live%
Open the casing so that coding plug �.d becomes
accessible.
Set the temperature selector to "OFF". The coding plug must
be set to T mom (standard delivery).
Set coding plug to T ; the setting mode will be activated and
the flashing display's'hows the current temperature limit.
Within the next 30 seconds, you can select the required
temperature (display continues to flash). The setting mode
will terminate after 30 seconds: the. programming unit will
display "OFF" again.

Stipbel Eltron Tempra tankless water heaters are designed for a
ve�y long service life. Actual life expectancy will vary with water
quality and use. The unit itself does not require any regular main-
tenance. However, to ensure consistent water flow, it is recom-
mended to periodically remove scale and dirt that may build up
at the aerator of the faucet(s), the filter screen in the unit, or in
the shower head.
