- The inside of the hot water tank should be thoroughly cleaned once a year. The primary circuit
should be drained first, before draining the hot water tank.
- If the hot water tank includes electronic cathode protection, this should be inspected once a year
to ensure it is functioning correctly.
- The pressure of the primary installation must be kept between 0.1 and 0.15 MPa (1 and 1.5 bar).
- Make sure the safety valve and the drain valve are working correctly.
- If the installation has been out of use for a long time, check the hot water tank feed pump is
working correctly. To do this, remove the front cover from the pump, leaving the pump shaft

shaft down with a suitably sized screwdriver and turn it in both directions. Then connect the
switch again.
It is recommended for the user to periodically check the pressure and temperature levels of the hot
water tank and the state of the valves, connections and accessories.
