Care And Maintenance Program - SOLE S150 Installation Manual

10. Care and Maintenance Program

• The collectors should be subject to periodic visual inspections. If it appears that
excessive dirt has been accumulated on the glass of the collectors, then it must be
cleaned. This operation should take place during the morning, before 10:00 am or in
the afternoon after the 18:00 pm, checking before that the collectors are not too hot.
Otherwise, there might be a risk of damaging the collector, (especially when using a
hose), or burning if manual cleaning is performed.
• If for some reason the collector's glass breaks, it should be replaced immediately.
Otherwise, the interior of the collector may deteriorate due to rain, humidity or dirt.
• During each inspection, visually check the possible loss of tightness in the closed-
circuit connections and the entry and exit of each collector and the connections
between them. Fix if necessary or replace items (parts) in poor condition.
• The support of solar collector is made of highly resistant galvanized steel. As a
precaution, check regularly their condition and repair if necessary. Verify also
fixations to the tile or flat roof.
• In the event that an extended period without hot water consumption is foreseen (for
example during holidays) it is recommended to cover the collectors with a blanket or
a similar opaque material or empty the collectors circuit, so as to avoid unnecessary
overheating. The cover of the collectors must be well fixed to avoid being gone by
the wind.
• The closed circuit of the collectors should be suitably protected against frost with
antifreeze liquid of the right characteristics. Particular attention should be given not to
reduce the concentration of antifreeze mixture, for example by filling with water.
