Water Treatment - EdilKamin Italiana Camini IDROPOINT Installation, Use And Maintenance Manual

PLUMBING
(FOR TECHNICAL ASSISTANCE CENTRE USE ONLY)
• IDROPOINT MUST NEVER OPERATE WITHOUT WATER IN THE SYSTEM.
• OPERATING PRESSURE MUST BE ABOUT 1.5 BARS.
• SWITCHING ON WHEN "DRY" CAN DAMAGE THE STOVE.
Plumbing must be carried out by qualified personnel and a declaration of conformity must be issued pursuant to Min. Decree 37
ex Law 46/90.
In any case, it is essential that the laws in force in the country concerned are followed.
• For the water input, return and discharge connections, opt for suitable solutions to facilitate, if necessary, a any future re-posi-
tioning of the stove.
• For better performance, the primary circuit (where the heat generator is situated) must be separate from the secondary circuit
(user).
For example, using a plate exchanger which allows the exchange of energy in the form of heat without mixing the waters.

WATER TREATMENT

It may be necessary to add anti-freeze, anti-scaling and anti-corrosion additives suitable for light alloys.
If the water for filling and topping up the stove has a hardness of above 35°F, use a water softener.
For suggestions, consult the standard UNI 8065-1989 (Water treatment in heating systems for civil use).
NOTES ON THE RETURN WATER TEMPERATURE
A suitable system which guarantees a return water temperature of no less than 45° - 50°C is required.
N.B.
• The installer must assess whether an extra expansion tank is necessary, according to the type of system served.
• During the production of domestic hot water, there is a temporary reduction in supply to the radiators.
• FIRST IGNITION
Check that the plumbing is correct and that the expansion tank is sufficient to guarantee safety.
The existence of the tank built into the stove does NOT guarantee adequate protection against the increased volume of the heated
water of the whole system.
Switch on the electricity to the stove and carry out testing while cold.
Fill the water circuit using the loading connection (the recommended pressure is about 1.5 bars).
During loading, "bleed" the pump and open the manual bleed valve (see page 211).
This operation must also be repeated periodically.
