Always Observe The Following; Circulation Connection; Heating Inserts - Atlantic Mileo Bedienungsanleitung

Always observe the following:

To ensure proper function of the fitting, the latter must be installed only in a frost-protected space. The safety valve runout
must be open and visible and the waste line of the drip catcher (expansion water funnel) must be routed to the waste water
duct so that neither frost nor obstructions caused by dirt and such can cause a problem. Ensure that the drip cup or item to
be drained is free of deposits and soiling.
No shut-off valve or other restriction may be installed between the safety valve and cold water inlet of the water heater.
The safety valve must be set to a response pressure which is less than the rated pressure of the tank.
Before finally connecting the tank, flush the cold water line.
After making the water connection and air-bubble free filling of the tank, check the fitting for proper function.
When lifting or turning (venting) the safety valve test button, the water must flow out freely and without backing up through
the expansion water outlet funnel.
The discharge openings of the safety valves (domestic water and heating circuits) must open out into an appropriate draina-
ge object in order to avoid any damage caused by the escape of operating fluid.
To check the return valve, the shut-off valve must be closed and no water may flow out from the opened test valve. The safety
valve must be checked according to DIN 1988-8 or ÖNORM B 2531-1.
The water heater is operated using the hot water valve on the service water fitting. This means the tank is under continuous
line pressure. To protect the internal boiler against overpressure when heating up, the expansion water created is dispersed
through the safety valve every time it is heated. The return valve prevents hot water from flowing back into the cold water line
when there is a pressure drop and thus protects the boiler from heating when no water is present.
The shut-off valve can be used to isolate the tank on the water side and thereby eliminate the pressure from the cold water
supply, also allowing use of the waste valve when necessary.
In order to allow for a trouble-free repair, a removal or exchange of the device, it is necessary to establish the connection of
the tank by means of a detachable connection (Dutch). Tank leaks as a result of an improper connection and resulting dama-
ge and consequential damage are excluded from the warranty and product liability.

3. CIRCULATION CONNECTION

Due to significant energy loss, a circulation connection should be avoided when possible. If a highly branched service water
network requires a circulation line, this must be well insulated and the circulation pump controlled via a timer and thermos-
tat. The switching temperature of the thermostat should be kept low (45°C). The circulation connection piece has an external
thread.

4. HEATING INSERTS

Screw-in heater
Water heaters whose model name contains an „..M..", are fitted with a 1 1/2" sleeve which can be used to install an electric
screw-in heater for supplementary or auxiliary heating. Screw-in heaters are designed technically as supplementary heating,
and should not be used for continuous heating (failure due to natural calcification is not a sufficient reason for claim).
Ribbed tube heat exchanger
All metallic insert (flush mounted) components having a larger metallic surface area (e.g., condenser insert heat pumps,
ribbed tube heat exchangers, electric heaters) must be electrically isolated from the water heater. In order to protect these in-
sert (flush mounted) components against current-induced corrosion, we recommend installing a defined contact resistance
of approx. 600 Ω (unless already installed in the components ex works). The water heaters may not be transported with the
ribbed tube heat exchanger installed. Installation must be performed on-site. Attention must be paid to full overlapping of
screw threads on all coupling sleeves. When installing a ribbed tube heat exchanger, make sure that the storage tank is still
protected against corrosion.
Therefore, an appropriate external current anode or magnesium reactive anode must be mounted when the magnesium
reactive anode is removed from the storage tank with the flange plate during assembly of a ribbed tube heat exchanger.
