GENERAL POINTS
The water heater with smooth-tube heat exchanger can be connected to each gas or oil furnace or to a solar system. The position of the heat
exchangers provides complete heating of the water in the accumulator.
The tank is protected by an enamel covering giving protection up to 850°C, in accordance with the requirements of DIN 4753.
The water heater must be installed by an approved installer, in an area that is protected against freezing. Enamelled tanks are suitable for nor-
mal domestic hot water. Important: the electrical connections are vital to prevent corrosion (iron, copper).
Unused connections must be blocked. The directives in force and the instructions from the local water service as well as DIN standards must
be followed.
The tank is linked to the hydraulic distribution network via a cold water connection and to usage points via a hot water connection.
If hot water is taken from a usage point, cold water then enters the reservoir where it is heated to the temperature set using the thermostat
(not provided with the product).
It is advisable to maintain the water temperature between 60° and 65°C, as this guarantees the best performance for the unit and ensures the
following:
- Maximum level of hygiene,
- Maximum limit for thermal loss,
- Limiting the formation of limescale deposits.
Special features :
- High performance coils: high heating power.
- Maximum operating pressure: see technical data.
- Temperature display.
- Adjustable feet for better positioning.
- Protection against corrosion using magnesium anodes.
- Outer nish: white painted sheet steel.
- Heat insulation: expanded polyurethane foam.
INSTALLATION
Installation instructions
ONLY QUALIFIED PERSONNEL ARE AUTHORISED TO PERFORM THIS OPERATION, OTHERWISE THE WARRANTY WILL BECOME VOID
The information given below determines the validity of the warranty.
1. The installation must:
a. Be installed by a qualied installer. You must conform to current national standards. It is necessary to respect
the instructions for the water heater,
b. Provide, when necessary, a pressure reducer for inlet water, (pressure > 4,5 bar).
c. The system is required to have a safety assembly (maximum calibration: 7 bar) which must be installed
with the unit in a location where there is no possibility of freezing.
2. The storage temperature must remain below 90°C
3. To prevent corrosion, the anodes must be checked every 12 months, however in areas with especially aggressive water, inspections
must be carried out every 6 months; if the anode has been destroyed, it must be replaced..
4. It is recommended that the generator be installed as close as possible to the boiler; in all cases, it is important that the connection piping is
insulated.
