Flange Insertion Opening; Central Heating Connection - Atlantic Mileo Serie Manual De Instalación

Electric built-in heater
Appliances with electrically powered built-in heaters are equipped with a safety temperature limiter which turns off further
heating of the appliance at a temperature of max. 110 °C (EN 60335-2-21; ÖVE-EW41, Part 2 (500)/1971). Therefore, select the
connection components (pipe fittings, circulation, safety valve combination, etc.) such that they will resist temperatures of
110 °C in the event of any possible malfunction of the thermostat and thus preventing consequential damage.
Assembly and installation may be performed only by authorized specialists.
A built-in heater, installed via the flange, is provided for continuous operation.
The built-in or screw-in heaters must be installed or designed with insulation (at least 600 Ω), as otherwise the tank interior
may corrode.
If the corrosion protection is built-in to the flange plate as standard, alternative corrosion protection must be provided if the
flange plate is removed.
Due to the hysteresis of the thermostat (±7 °K) and potential dissipation losses (cooling of the pipelines) the temperatures
can deviate by ±10 °K.
If the water heater is heated via its heat exchanger, ensure that the hot water temperature cannot exceed 85 °C under any
circumstances, as it could trigger the safety temperature limiter of the electric heater, and shut the heater down.
Important: all built-in metallic parts, such as coiled radiators, finned tube ribbed pipe radiators and/or integrated heaters, are
to be installed after being electrically insulated with respect to the storage tank. To protect the built-in parts from corrosion,
contact resistance of approx. 600 Ω is to be provided (unless already installed in the parts in the factory).

5. FLANGE INSERTION OPENING

Depending on the system design, electric built-in heaters or heat
exchangers can be installed on the boiler flange Ø240 mm (clear diameter
Ø173 mm, hole circle Ø210 mm, 12 x M12) and Ø180 (clear diameter Ø117
mm, hole circle Ø150 mm, 8 x M12).
Built-in electric heating elements are to be installed so that the thermostat
probe is at the top.

6. CENTRAL HEATING CONNECTION

The pipe register resp. the double shell must be rinsed prior to
commissioning in order to remove any possible contaminations (e.g. scale)
from the heating circuit. The heating water must be treated in accordance
with the national regulations and standards (e.g. ÖNORM H5195-1) during
commissioning and comply with the regulations.
Water heater with register
The bare-tube heat exchangers installed in the storage tank can be connected to a water heater if the pressure and temperature
correspond to the data stated on the specification label. Forced circulation using a pump is required.
When installing a water heater with register a shut-off member must be installed in the flow line to prevent back-heating into
the heating circuit when the central heating and heat pumps are turned off or for electrical operation.
The outgoing and return flow must, however, never be shut off, since otherwise the water in the register cannot expand and
three is a risk of damaging the water heater. The bare-tube heat exchanger must be properly rinsed before performing the
initial installation (we also recommend installing a dirt filter). If the bare-tube heat exchanger is not used when operating
the water heater (such as when electric heating only is used), fill it completely with an appropriate glycol mixture to prevent
corrosion caused by the resulting condensed water. The filled bare-tube heat exchanger is not permitted to be closed off at
both ends after filling (expansion pressure caused by temperature rise).
