Explain the functions of the unit to the user and familiarize
him or her with its use.
Important instructions:
» Draw the user’s attention to possible hazards
(scalding).
» Hand over these instructions for future reference.
» In order to obtain a proper temperature at a single
spout mixer-type faucet, restrict cold water fl ow to
faucet by partially closing the cold water shut-off
valve under the sink until cold water and hot water
fl ow rates are approximately the same.
10. Normal maintenance


CAUTION: OTHER THAN THE FILTER SCREEN, THE
Mini DOES NOT CONTAIN ANY PARTS SERVICEABLE
BY THE LAY PERSON. IN CASE OF MALFUNCTION PLEASE
CONTACT A LICENSED PLUMBER OR ELECTRICIAN.
Stiebel Eltron Mini tankless 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 recommended to periodically remove scale and
dirt that may build up at the aerator of the faucet or in the
shower head. Also, the Mini has a built in fi lter screen that
should be cleaned from time to time. In order to do this,
turn off the cold water supply at the isolating valve. Clean
screen and put the screen back into its original position.
