■ Have the small water heater connected only by
a specialist.
■ Observe the legal regulations as well as the connection
conditions of the electrical power company and the water
works.
Caution!
Fill the unit completely with water first and then plug in
the mains plug. Otherwise the temperature fuse will
melt and must be replaced by customer service.
■ Connect the unit only to a mains socket with protective
contact that is installed according to regulations. Do not
use an extension cord. If necessary, equip the unit with a
longer cord (see Section I).
■ The small water heater may be used only open
(unpressurised) and for one tapping point. The warm
water outlet serves for pressure equalisation and
may be connected only to special mixing batteries
(Order-Nr. BZ 13051 or BZ 13061).
■ The outlet of the battery must always be free.
Do not use a aerator (air mixer).
■
During heating, expansion water drips from the outlet.

■ After mounting, please give the instructions for use to
the owner and explain the unit to him.
■ Maintenance and repair work should only be
performed by a qualified professional.
■ The appliance should not be supplied power via a timer
switch. Otherwise, there is a risk of an unintentional reset
of the protection temperature limiter during a
malfunction.
Disconnect the power supply before
opening the appliance!
