General safety precautions
▪ Establish the power supply in ac-
cordance with IEC 60335-1, via a
separate isolator which separates all
poles with a contact opening dis-
tance that provides full disconnection
in accordance with overvoltage cat-
egory III.
▪ All electrical work must only be car-
ried out by electrically qualified ex-
perts and with consideration of the
local and national regulations and
the instructions in this manual.
Ensure that a suitable electrical cir-
cuit is used.
Insufficient load capacity of the elec-
trical circuit or improperly executed
connections can result in electric
shock or fire.
▪ The customer must install a pressure
relief device with a rated over-pres-
sure of less than 0.6 MPa (6 bar).
The connected drain line must have
a continuous gradient and a free out-
let in a frost-free environment (see
Chap.
3.3).
▪ Water may drip out of the drain line
of the pressure relief device. The
drain opening must be left open to
atmosphere.
▪ The pressure relief device must be
operated regularly in order to re-
move scale deposits and to make
sure it is not blocked.
▪ The storage tank and hot water cir-
cuit can be drained. The instructions
in
Chap. 8.1
must be observed.
