Maintenance And Shutting Down The System - Fondital Sulpack Natural Plus 150 Manual De Instalación, Uso Y Mantenimiento

5.5 Maintenance and shutting down the system

Maintenance and repair operations must only be carried out by qualified technical personnel in possession of the necessary
safety equipment. The system's proper maintenance will ensure optimal working conditions, thus ensuring complete safety for
people, animals and property, while at the same time maintaining the system's performance and functionality levels unaltered
over time.

WARNING
Maintenance work must be carried out with the system cold. Prior to performing any maintenance work, always make
sure that the water in the boiler and the solar liquid in the system have not reached high temperatures. If necessary,
cover the collectors with non-transparent materials and wait until the system has cooled down.
The system must be regularly checked and documented according to the checklist contained in the present manual (12 Check
list). Six months after the installation it is recommended to be checked some points such us valves, screws, mg anode etc.
During shutting down the collectors must be covered by a non-transparent material. Ensure that the electrical element is not
switched on. If required to remove the electrical element or the mg anode, make sure that there is no hot water in the tank.

WARNING
Open carefully screwed parts, as the tank is operating under pressure.
Maintenance schedule
The boiler must be serviced at least once every year.

WARNING
Prestare molta attenzione al liquido solare contenuto nei collettori poiché può raggiungere temperature molto elevate e
può ustionare.
Routine maintenance schedule are to include the following:
Inspections and checks
-
check efficiency of the system safety valve.
-
Inspection and possible replacement of magnesium anodes.
-
Verification of the frame elements' tightness.
-
Verification that the installation is in good condition.
-
Inspection of the connection pipes.
The following cleaning is to be done
-
Cleaning the solar collector's glass.
Be sure to purge any air present from the system during commissioning and after every maintenance or repair operation.
Also check:
-
the pH of the Heat transfer fluid.
If the DHW circuit has not been used for an extended period of time, the safety valve may open, causing water to leak out.

WARNING
The safety valves' drains should be channelled into the sewer system. If this precaution is not taken, the installation area
could be flooded in the event that the safety valve is triggered. The manufacturer shall bear absolutely no responsibility
for any damage caused by the opening of the safety valve.

WARNING
In the case of disuse, the solar collector must be covered in order to prevent it from overheating. The absence of a cover
or the non-consumption of water can result in the need for the circuit to be purged, thus requiring the heat transfer fluid
to be topped up.
