Working Principle; Water Connections - Thermor IAV 75 Manual De Instrucciones

WARNING
This device is not intended for use by persons (including children) with physical, sensory or mental disability, or by persons lacking experience or knowledge, unless they have
received from a person in charge of their safety adequate supervision or preliminary instructions on how to use the device.
Care must be taken at all times to keep children from playing with the device.
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
A)INSTALLATION
Warning: Heavy items, to be handled with care
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.
st
2 ) Ensure that the wall is capable of supporting the weight of the device when full of water.
nd
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
rd
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.
th
If using PER pipes, we strongly recommend that a thermostatic regulator be fitted to the water heater outlet. It will be set according to the performances of the equipment used.
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) WATER CONNECTIONS
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, pressure between 7 and 9 bar (0,7 and 0,9 MPa) and size
3/4" (1" : 500 l) MUST be fitted to the water heater inlet. The safety valve must be protected from frost. 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-0,5 MPa. Connect the safety device to an
unpressurised outlet pipe in a frost free environment, with a continuous slope for the evacuation of the water during heating up or draining the water heater.. Pipes used must be
capable of withstanding a temperature of 100 °C and a pressure of 10 bar-1MPa. The pressure of the cold water system is usually below 5 bar-0,5MPa. 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-0,3MPa 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-0,3MPa, its temperature must not exceed 100°C.
