The LATENTO XXL is very easy to maintain. The only periodic work would be
checking the water level and the system pressures.
half-yearly
Check the water level in the LATENTO XXL: The float must be between "Min" and
"Max". Ideal is the middle position "OPT". When required, refill the storage
tank, as on page 32 described.
Check the system pressure of the solar, boiler and heating system – correct
pressure appropriately, whenever required.
whenever required
Should the performance of the DHW heat exchanger fade, you will need to
rinse or descale it. The intervals for this work depend on the hardness of the
drinking water and the temperatures in the storage tank.
The solar liquid must be checked in case the power of the solar yield should
fade (at existing solar radiation!). Exchange possibly flocculated or brown dis-
coloured solar liquid.
Exchange the solar liquid depending on manufacturer information.
