Installation
General remarks
•
Connections (electrical, hydraulic) must be carried out in accordance with
applicable standards and regulations.
•
If the water drawing off point is far from the tank, installing an auxiliary DHW
loop can allow to get hot water more quickly at all times.
Essential instructions for the correct operation of the system
•
The water heater must be installed in a dry location, that is protected against
frost (min 4 to 5°C ambient temperature).
•
Install the appliance to ensure easy access at all times.
•
To avoid any risk of corrosion, connect the stainless steel tank directly to the
earth. Use an adjustable earth clamp (see example below) on one of the DHW
connections to connect to the earth. Advised copper wire section: 2.5mm².
•
Make sure to install a pressure reducing valve set at 4.5 bar in the DHW circuit if
the supply pressure is higher than 6 bar.
•
On the cold water inlet of the domestic circuit, install an approved safety group,
comprised of a safety valve set at 7 bar, a check valve and a stop valve.
•
Make sure that the outlet of the safety group goes directly downards to the
sewer to avoid any potential damage.
•
Do not install the safety group above the water heater to avoid water discharge on to
the appliance.
•
If the water heater is installed above inhabited rooms, make sure to place a collection
container under the appliance to collect any leaking water.
