Working Principle - Atlantic ECHANGEUR OPTIMISÉ Bedienungsanleitung

Important : Installation of the water heater must comply with national standards in the country of installation. If you are not sure that your knowledge is sufficient to install this
product, we advise you to consult a professional.
IMPORTANT FOR MODELS WITH ACI: A 3 solid core power cable form the appliance powering your anti-corrosion protection (ACI) system is ready to be
connected to the bridging terminal, powered 24/24 hours.
Forgetting to make this electrical connection to a permanent (230V) supply, will entail loss of the manufacturer's guarantee.

WORKING PRINCIPLE

1. IN WINTER (heater switched on)
Your heater operates and provides bathroom water heating through the circulation of a hot fluid inside an exchanger (optimized exchanger) ((E)
2 IN SUMMER or in mid-season (heater switched off) for operation with an electric kit (not supplied as standard).
Your heater is switched off. Heating is carried out by switching on the power. The thermostat interrupts electrical heating when the water temperature reaches 65 °C

Warning: Heavy items, to be handled with care
st
1 ) Install the device in premises free from frost. Destruction of the device by overpressure due to blockage of the safety unit is outside the guarantee.
nd
2 ) Ensure that the wall is capable of supporting the weight of the device when full of water.
rd
3 ) If the device is to be installed in premises or a location whose ambient temperature is permanently above 35°C, provide ventilation of the premises
th
4 ) In a bathroom do not install this product in volumes V0 and V1 (see fig. 1). If the water-heater is installed above habitable premises provide a storage tank with outflow to the
drains .
th
5 ) Fit the device in an accessible place.
INSTALLATION OF A VERTICAL WALL MOUNTED WATER HEATER: To enable change of the heating element, if required, leave space below the ends of the pipes
of the appliance. Appliances can be mounted on a tripod (optional) if the wall is not strong enough. It is, however obligatory for the upper bracket of the water heater to be
attached to the wall to prevent tilting. (fig. 2)
INSTALLATION OF A FLOOR STANDING WATER HEATER The water heater must be installed absolutely vertically in such a way as to guarantee absolute stability
with access to electrical parts and safety parts. Allow for access to parts which might need replacing.
B) W A T E R C O N N E C T I O N S
All water supply pipes must be thoroughly cleaned before connection. The connection to the hot water outlet must be made using a cast iron or steel sleeve or a dielectric union in
order to avoid corrosion of the tubes (due to direct contact between iron and copper). A brass union must not be used.
Secondary Circuit (fig. 4/5 or 6): A new safety device that complies with the applicable standards (in Europe EN 1487) MUST be fitted to the water heater inlet. No water
accessory must be installed between the safety device and the cold water inlet to the appliance. A pressure reducing valve (not supplied) is recommended when water supply
pressure exceeds 5 bar. Connect the safety device to an outlet pipe to drain off the heat-expanded water or to allow for drainage of the water heater. Pipes used must be capable of
withstanding a temperature of 100 °C and a pressure of 10 bar. The pressure of the cold water system is usually below 5 bar. If that is not the case, put a pressure reducer on the
main feed, after the meter.
Possible recycling circuit: If the location of the appliance is distant from the last supply point, a distribution ring can be made. Water will be circulated with a pump (E.C.S.). If
the pipework goes outside ensure that the plumbing is insulated. As to connections it is essential to comply with the same recommendations as those for the secondary circuit
(pipes, connections). Recycling allows hot water to by available quickly, in the case of distant water supply(ies), this can cause a lower storage temperature. In summer,
permanent electric supply is required (optional electrical kit)
Primary circuit (heating): Protect from excessive pressure due to expansion of water during heating with a 3 bar valve or a header tank of the open (to atmospheric pressure)
type or a closed type diaphragm tank. The circuit working pressure must not exceed 3 bar, its temperature must not exceed 100°C.
WORKING PRINCIPLE WITH BOOSTER PUMP: Supply a pump (optional kit) the aquastat diverter valve, which is fitted in series, is put in the pocket as the bulb of the
tripolar electric thermostat controlling the electrical power. Make an electrical connection between the aquastat and the booster pump control. The recommended setting for the
aquastat is 65°C (factory setting) and of the tripolar electric thermostat controlling the electrical supply on maximum i.e. 65°C.
Connection in series: Where several appliances are connected in series, ensure that the safety units are capable of accepting high temperatures.
