10 MAINTENANCE
Maintenance must only be carried out by qualified staff. All work carried out on the system must be
done by the Official Technical Assistance Service, as changing the configuration could cause
functioning errors and damage to the system and its surrounding environment.
10.1 Cleaning the inside of the tank
The inside of the domestic hot water tank should be thoroughly cleaned once a year.
The upper part of the stainless steel tank is equipped with an access opening, for ease of cleaning.
If the hot water tank has an electronic cathode protection, this should be inspected once a year to
ensure its correct functioning.
10.2 Checking the safety valve
Check the safety valve is functioning correctly by injecting air into it. If water comes out or if it does
not close hermetically, replace it.
10.3 Collectors
The state of the collector supports should be checked periodically.
10.4 Draining the solar circuit
If the solar circuit needs draining, the
procedure is as follows:
1. Connect a hose to the filling/emptying
valve and another hose to the level
valve.
2. Run the hoses to a suitable container.
3. Open the filling/emptying valve and the
level valve.
4. Completely drain the solar heating
circuit (see table below).
5. Disconnect the hoses used.
