Maintenance

Advice after instalation
 Control once a year the level, pH and proportion of the thermal fluid. Refill
if necessary. The thermal fluid must be changed every 2 year.
 In dusty areas and low rainfall we advise to clean with water and a cloth
the glass collector, if these are clearly dirty.
 In case of glass collector breakage, the whole collector must be replaced by a
new one.
 Check seals, valves, connections and thermal insulation status once a year. In
addition, it must be controlled the general status of the structure with its
bolts and screws.
 Magnesium anode must be checked and changed if necessary once a year.
 If collectors are easily accessible, cover them with an opaque coverage du-
ring long absences in order they do not work uselessly.
 Especially in hard water cases it is convenient to install a suitable filter in
the water inlet to the house.
Protection against calcareous incrustations
 To keep the performance of the equipment steady throughout the time
and prevent corrosion problems, it is necessary to install a decalcification
system or lime inhibitor (Polyphosphates doser)
 It is necessary to verify the correct functioning of the doser in the annual inspection.
Troubleshooting
Attention!
 Before opening the tank, the primary circuit or manipulate the electrical re-
sistance cap, close the cold water input and disconnect the electrical current
 Danger of burning with the tank's water or with the thermal fluid!
 Any control or manipulation of the electrical installation must be done by a
licensed electrician
If the equipment does not heat with the sun:
Possible causes of malfunction:
1. There is not enough thermal fluid: If there is not enough thermal fluid, the
thermosiphon does not work. You should locate and correct possible leaks in
the collector connections to the tank or in the connections between both
collectors or in the collector's plugs. Then you must refill thermal fluid and
purge.
2. The go and return flexible hose have not inclination, stopping the flow of the
primary circuit.
3. Air in the primary circuit, you must purge it.
4. The equipment is not placed on level.
