8. Mounting and Safety Information
E
a)
Important mounting information! Do not bend hang-up hook safety
element due to possible fracture. Risk of injury by falling device in
the case of non-observance!
b) A wall rail for hanging up the upper fastening hook is enclosed with every
device, which is mounted to the wall using two screws and takes over the
supporting function.
Two additional screwed connections must be provided on the wall (in
accordance with the dimensioned drawing with the device dimensions)
for the lower wall plate of the device; this has only a supporting function
against the wall as well as against lateral shifting. Hot water heaters of a
suspended type must not be mounted horizontally.
c) The fastening hooks and with that the hang-up dimension A can be adju-
sted at intervals of 50 mm by repositioning the rear tank wall screws into other holes of the
hook
(only for 50 – 150 litres).
Caution
: only use the fastening hook provided by the company AE!
d) The dimensioned device drawings and any information labels that may be enclosed must be
observed during mounting.
e)
Caution
: the weight of the water heater including the weight of the water filling (the rated capacity)
must be taken into account for load-related and strength-related design of the device mounting
surface or selection of the mounting location.
Special suspensions: see thin-wall and/or ceiling suspension.
f) If a water heater is provided with enclosures (covering), installed in narrow, small rooms or in
suspended ceilings and the like, it is absolutely important to check that the connecting side of the
device (water connections, electric connecting area or heating unit) remains freely accessible and
no accumulation of heat results. A free space of 500 mm must be available for de-installation of
the heating flange. A space of at least 50 mm must be kept free above the device for hanging it
up on the wall rail.
g) Any electrochemical processes that may be possible (contact corrosion, e.g. copper – steel) must
be taken into account according to the rules of technology when selecting or arranging the order
of insulation material used on the part of the system (caution with mixed installations). We recom-
mend the installation of insulated screw fittings.
h) If particularly aggressive water is available that requires special solutions on the part of the instal-
lation, then the possible need for special tank designs should also be reviewed (consultation with
our representations or with our company).
i) The device is equipped with a safety temperature limiter, which stops any further heating of the
device from a water temperature of max. 110 °C (EN 60335 -2-21; ÖVE-EW41, Part 2 (500)
/1971). Therefore, the connecting components (connecting pipes, safety valve combinations, etc.)
must be selected in such a way that they resist temperatures of 110 °C and any consequential
damages are avoided in the case of a possible malfunction of the temperature control.
j) Mounting and installation must be performed exclusively by licensed craftsmen.
