Rust Protection Magnesium Anode (For Water Heaters With Water Tanks Covered By Glass-Ceramics Coating); Operation; Switch On; Water Heaters With Electromechanical Control - Bosch Tronic 3000 T Installation Instructions Manual

16 | Εlectric water heater
For water heaters with electric power
4000 W, this connection to the electric
system is done by means of a three core
copper cable 3x4 sq.mm. to a separate
circuit circle, protected by a 20A safety
device.
The electrical circuit supplying the appli-
ance must have an in-built device ensur-
ing the splitting of all terminal poles un-
der conditions of
category III.
To install the power supply wire to the
boiler, remove the plastic cover (Fig.2 a,
b, c, d - according to the purchased
model).
Connect the power wires in compliance
with the marks on the terminals, as
follows:
- the phase - to mark A, A1, L or L1;
- the neutral - to N (B or B1 or N1)
The safety wire must be obligatory con-
nected to the screw joint marked with
. After the installation, put the plas-
tic cover back in its place!
Note: For models with externally adjustable ther-
mostat (shown on Fig. 2c), dismount the handle
before mounting the cover by pressing it from
the internal side till it gets detached from the
plastic cover. Mount the plastic cover again, af-
terwards set the handle on its place by pressing
it to click in.
V. Rust protection magnesium
anode (for water heaters
with water tanks covered by
glass-ceramics coating)
The magnesium anode protects the wa-
ter tank's inner surface from corrosion.
The anode's term of use is up to five
years. The anode element is an element
undergoing wear and tear and is subject
super-voltage of
to periodic replacement.
In view of the long-term and accident
free use of your water heater, the manu-
facturer recommends periodic inspec-
tions of the magnesium anode's condi-
tion by a qualified technician and
replacement whenever required, and
this could be performed during the ap-
pliance's technical
maintenance.
For replacements, please contact the au-
thorized service stations!
VI. Operation

1. Switch on:

Before switching on the appliance for
first time, make sure that the boiler is
properly connected to the power supply
network and full with water.
The boiler is switched on by a switch in-
tegrated into the installation, described
in item 3.2 of Section IV, or upon con-
necting the plug to the electrical contact
(in the case of an extension cable with
plug).
