INSTALLATION
THIS OPERATION MUST BE MADE SOLELY BY QUALIFIED PERSONNEL, PENALTY THE LOSS OF WARRANTY.
2.1.
FIRST CHECK
This cylinder has been designed, manufactured and tested for the storage of domestic hot water within the limits of temperature and pressure indicated
in the chapter "technical data" and on the id label applied on the product itself. Any use beyond the allowed limits should be considered dangerous and
not suitable.
2.2.
PLACEMENT
install the cylinder sheltered from the weather
install the cylinder as close as possible to the primary heat source
install the cylinder on a flat surface of suitable strength, able to support the weight of the product once filled with water
check that there is enough space around the tank in order to perform future maintenance
verify that the room where the tank is located has openings of a size to allow the free passage of the cylinder, in case it's necessary to bring it
out, in order to avoid any demolition.
2.3.
START
The connection diagram shown in this document is purely indicative and not binding. it's up to the designer of the system to choose the best
connection scheme for the required application, in accordance either with the applicable regulations and with the limits imposed by the data
declared by the manufacturer.
The connection to the water mains must be done through a safety hydraulic kit including:
- 1 shut-off valve
- 1 check valve
- 1 safety valve
- 1 stop device of water supply
all the above accessories are necessary to make the tank installation safe from dangers
provide the system of an expansion vessel including a relief valve (of counterweight or spring type) having a diameter not less than
where V is the volume in litres of the cylinder, with a minimum of 15mm. The valve must be set at a pressure not exceeding
the maximum working pressure of the tank
make sure that the volume and the pre-charge pressure of the expansion vessel of the secondary circuit are suitable for the installation
if the sanitary water system exceeds the maximum pressure allowed for the cylinder, install a pressure reducer as far away as possible from
the storage tank
in case the calcium value of the water coming from mains is too high, install a properly sized softener (before the storage tank)
in case impurities are contained in the water coming from mains, install a suitable filter
make sure that the pumps have enough flow and head and work correctly
make sure that the thermometer and thermostat probes are positioned correctly
always perform the grounding of the tank
in case the users are many, located far from the unit, and require discontinuous supply of water, the installation of a recirculation pump is
suggested, in order to keep constant the temperature of the domestic hot water. This way it's possible to avoid long waits and waste of cold
water
the insulation of the connecting pipes is always recommended in order to avoid unnecessary heat loss
