Technical Installation Instructions and User Guide
Notes for the user :
• The tank is linked to the hydraulic distribution network via a cold water connection and to usage points via a
hot water connection.
• The hot water is preheated or heated by solar energy using the bottom coil.
• Regularly check that all the control, regulation and testing devices are functioning properly.
Always use new connection piping to make connections to a water supply network, never install used pipes.
These pipes must also conform to the EN 61770 standard.
CARE AND MAINTENANCE
THE CURRENT MUST BE CUT BEFORE ANY OPERATION IS CARRIED OUT ON THE UNIT
GB
All operations must be carried out by a qualified technician.
We recommend subscribing to a maintenance contract and planning to replace the safety assembly at least every 5 years, if necessary. The
safety unit must be used every month.
Every year (twice a year if the water is treated by a water softener), the unit must be drained so that :
1) The magnesium anode wear can be checked: if the diameter is less than 10 mm or its volume is less than 50% of its initial volume, it must
be replaced.
2) Deposits inside the tank can be removed.
For these operations, contact your trusted installer.
Exterior cleaning
The external parts of the tank must be cleaned using a damp cloth and appropriate cleaning products that are available commercially. In any
case, the use of abrasive products, solvents, spirits, alcohol, etc. is not recommended.
Draining
Shut off the cold water inlet.
Open the drainage valve on the safety assembly.
Open the hot water valve to let air in.
Remove limescale
In cases of very hard water, it is advisable to remove limescale at least twice a year.
To do this, it is first of all necessary to empty the hot water tank and then remove the upper flange to be able to ac-
cess the interior. Carry out the task using a suction device and a plastic or wooden brush (to remove the most
resistant sediment). Clean it again and rinse it with a spray of water.
While cleaning, be careful not to damage the enamel layer that protects the inside of the reservoir.
Replace the upper flange, install a new seal and fill the reservoir, making sure there are no leaks.
