1.3 Operating
 Select the temperature with the left-hand
temperature tap (2).
 Turn on the water with the right-hand
water tap (3).
1.4 Important note
When the water is being heated in
the heater, its volume increases. The
expansion water must be allowed to drip
out th­rough­ th­e fitting outlet. Th­is is a nec-
essary and normal process.
Stiebel Eltron water heaters SNU 5 SL with
"antitropf" -anti-drip- function retain the
expension water.
Limescale formation may block the outlet,
and so put the heater under pressure.
Never close off th­e fitting outlet, and do
not use any foaming elements (perlators,
aerators), flow limiters, or h­oses with­ jet
regulators, since the heater will otherwise
be damaged.
1.5 Care and maintenance
Only a damp cloth is required to clean the
fitting. Do not use any abrasive or corrosive
cleaning agents.
A jet regulator (12) which is blocked in lime
scale must be cleaned.
To clean the lime scale, the jet must be
removed from the jet regulator.
1.6 Operating and Installa-
tion Instructions
Keep th­ese Instructions carefully. In
the event of change of user, give them
to th­e new owners. If any maintenance or
repair work is required, give th­ese Instruc-
tions to th­e qualified fitter for h­is guidance.
