1. GENERAL
1.1 Description of the apparatus
The construction and equipment of the
electric storage heater meet the European
standards for electric household apparatus
(EN60335-1 and EN60335-2-21). Thus, the
heater is in conformity with the European
directives of electric household apparatus,
implying the authority to bear the CE-mark.
The heater is appropriate for a working power
of 8 bar (=800 kPa). The tank is of steel plate
and has got a glasslined coating, in its
interior. Simultaneously, the tank is provided
with two sacrificial anodes, as an additional
protection against corrosion. A thick FFC
insulating layer, surrounded by a steel casing
is preventing it from an unnecessary loss of
heat. As soon as the heater will be
completely filled with water, it will continually
be under the pressure of the water supply.
Draining hot water, the heater will
immediately be refilled with cold water. A
good transmission of heat is given by the use
of incoloy heating elements.
Additional comfort can be created by making
use of a circulation pipe with the
corresponding pump. The connection of the
above pipe will have to take place at the cold
water pipe.
1.1.1 Packaging material
The packaging protects the device against
transportation damage. The selected
packaging material is environmentally
friendly, recyclable and can be disposed of in
a relatively easy and environmentally friendly
way.
1.1.2 Disposal
Old and discarded devices contain
substances that are to be recycled. Please
take the local laws with respect to waste
processing into account when disposing of
