All Tankless Models
Stiebel Eltron tankless water heaters are designed for a very
long service life. Actual life expectancy will vary with water
quality and use.
In areas with hard water that produces scale, descaling of
the entire unit may be required, and should be performed
as often as necessary. We recommend the Flow-Aide System
(Stiebel Eltron part # 540000) for this procedure. In these
areas, consideration should also be given to installing a filter
that will prevent scale buildup on the cold water supply to
the water heater. We recommend the Scale TAC-ler Water
Conditioner (Stiebel Eltron part # 692442) for this.
Scale and dirt may build up in the filter screen in the unit
and should periodically be removed. Following all directions
and precautions in this manual, regularly clean the filter
screen and replace if necessary. Always shut off power to the
unit at the circuit breakers and water at the unit’s isolation
valves prior to removing the filter screen.
Scale and dirt build up may also occur at the hot water out-
lets served by the unit, such as the faucet aerator, or shower
head. Keeping these filter screens clean will ensure consis-
tent water flow.
CLEANING: Use a damp cloth to clean of the unit’s housing.
Do not use any abrasive or corrosive cleaning agents.

Following all directions and precautions in this manual,
regularly clean the filter screen located in the cold water
inlet connection and replace if necessary. Descaling can be
done using a descaling solution or household vinegar.
To access the filter screen in a Mini
™
, always shut off power
to the unit at the circuit breakers and water at the unit’s
isolation valves prior to removing the filter screen. Then
disconnect the cold water supply at the unit. Remove the
filter screen by reaching up into the cold inlet pipe with a
small flathead screwdriver and while putting pressure on the
inside of the screen’s plastic rim, pull the screen down and
out. Clean and replace the filter screen, or install a new one.
Never run the unit without the filter screen in place.

! DANGER: BURNS
WATER TEMPERATURES OVER 125°F (51°C) CAN CAUSE
SEVERE BURNS INSTANTLY OR DEATH FROM SCALDING.
A HOT WATER SCALDING POTENTIAL EXISTS IF THE
THERMOSTAT ON THE APPLIANCE IS SET TOO HIGH.
HOUSEHOLDS WITH SMALL CHILDREN, DISABLED OR
ELDERLY PERSONS MAY REQUIRE THAT THERMOSTATS
BE SET AT 120°F (48°C) OR LOWER TO PREVENT
POSSIBLE INJURY FROM HOT WATER.
CAUTION: OTHER THAN THE FILTER SCREEN, THESE
APPLIANCES DO NOT CONTAIN ANY PARTS SERVICEABLE
BY THE LAY PERSON. IN CASE OF MALFUNCTION, PLEASE
CONTACT A LICENSED PLUMBER OR ELECTRICIAN.
