6.2 Cleaning of solar combi- tank
V
Inspect tank interior for lime deposits.
When solid lime deposits are observed in the tank, pro-
ceed as follows:
V
Rinse out inner surface with a strong cold water stream
58 – 72.5 psi (4 to 5 bar).
When you heat up a drained solar hot water tank prior to
the water spraying, you can increase its effectiveness
drastically. The lime deposits will break off the heat
exchanger units due the thermal shock.
V
Remove any solid debris with a wet vacuum from the
tank interior.
In case of extreme hard and solid deposits, you can
remove these through a chemical cleaning. We recom-
mend you have a professional perform the chemical clean-
ing.
Caution: Tank damage due to damaging of
the tank surface.
V
Do not use any hard or sharp objects to
clean the tank interior.
