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 fi xed temperature of 109°F
(43 °C).
- Insert the coding plug into position Tred (reduced temperature).
2. Select a specifi c outlet temperature
- Switch the appliance 'live'.
- Open the casing so that coding plug T
max
/ T
red
becomes accessible.
- Set the temperature selector to "OFF". The coding plug must be
set to T
max
(standard delivery).
- Set coding plug to T
red
; the setting mode will be activated and
the fl ashing display shows the current temperature limit.
- Within the next 30 seconds, you can select the required tem-
perature (display continues to fl ash). The setting mode will
terminate after 30 seconds; the programming unit will display
"OFF" again.
8. Putting the water heater into oper-
ation
!
WARNING: OPEN HOT WATER FAUCET FOR A FEW MIN-
UTES UNTIL WATER FLOW IS CONTINUOUS AND ALL AIR
IS PURGED FROM WATER PIPES. THE UNIT’S COVER
MUST BE INSTALLED BEFORE THE CIRCUIT BREAKERS
ARE TURNED ON.
1. Close the cover and fi x it using the screw with chopper disc.
2. Turn on circuit breakers to bring electrical power to the unit.
3. Turn the temperature selector clockwise and anti-clockwise, to
calibrate the set value transducer.
4. Adjust the water temperature to the desired level using the knob
on the front cover of the unit.
5. Turn on hot water and wait twenty seconds until temperature
has stabilized.
6. Check the water temperature with your hand and make sure
that it does not feel too hot. Reduce if necessary.
7. Explain to the user how the unit works and familiarise him
or her with its use.
Advise the user about possible hazards (hot water temperature
up to 140 °F / 60 °C). Hand over these instructions, to be kept
for future reference.
9. Normal maintenance
!
NOTICE: THE TEMPRAS DO NOT CONTAIN ANY PARTS
SERVICEABLE BY THE LAY PERSON. IN CASE OF MAL-
FUNCTION PLEASE CONTACT A LICENSED PLUMBER OR
ELECTRICIAN.
STIEBEL ELTRON TEMPRA tankless water heaters are designed
for a very long service life. Actual life expectancy will vary with
water quality and use. The unit itself does not require any regular
maintenance. However, to ensure consistent water fl ow, it is rec-
ommended to periodically remove scale and dirt that may build
up at the aerator of the faucet(s), the fi lter screen in the unit, or
in the shower head.
