6.2 Cleaning of solar hot water 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) (Æ Fig. 20).
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 coils due the thermal shock.
V Remove any solid debris with a wet vac from the tank
interior.
In case of extreme hard and solid deposits, you can
remove these through a chemical cleaning. We recom-
mend to have a professional perform the chemical clean-
ing.

clean the tank interior.
