• The solar water heater will reach opti
-
mum performance two days after the
installation. During these two days, it is
recommended to avoid hot water con
-
sumption, even if there is sunshine.
• Check every year the level of the fluid in
the closed circuit.
• In regions with a lot of dust, we recom
-
mend that you clean the glass of the col
-
lector with water, every two months in
order to remove the dust from the glass,
unless there is enough rain.
• In case of glass damage, replace the
glass immediately to avoid further dam
-
age of the collector.
• For all water heaters, the main princi
-
ples and codes require that the function
of the valves is checked once a year.
We also recommend that during the
same period you check the screws,
nuts, plates, moly plugs, screw nuts
and support plates, for looseness or any
damages, especially when the appli
-
ance is installed near the sea. In case
of damages, they must be replaced by
owner’s expenses.
• During a long absence (such as summer
holidays), it is recommended to cover
the collector(s) with an opaque cover.
• Once the storage tank is filled in with
water, it must not get empty (evacu
-
ated) for many hours, and only if there
is a need for changing the magnesium
rod or the electrical resistance for which
it is required a short time, since there
is the possibility of creating cracks and
detachments in the internal protection of
the storage tank.
• In areas where the water supply pres
-
sure exceeds 6 Bar it is necessary to fit
a pressure reducer.
TROUBLESHOOTING
A. IF THE SOLAR
HEATER DOESN’T
SUPPLY HOT WATER
WITH THE SUN
1. Check carefully all the connections of
the solar water heater for leaks.
2. Check the fluid level in the closed cir
-
cuit and fill it, if necessary (see instruc
-
tions, page 18).
3. Check the connection tubes (05) and
(18) to ensure that they are not bented
or twisted
4. Ensure that there is no air trapped
inside the collector and the storage
tank
5. Ensure that the solar water heater is
installed in horizontal position.
6. Ensure that the supply of hot water
is not connected to a supply of cold
water.
7. Check the plumbing piping of your
house as well as the taps for slow
leaks.
8. Ensure that the storage tank’s and col
-
lector’s connections are properly made
and they are fully water tight.
9. Ensure that there is no obstacle (build
-
ing, tree etc) shading the solar water
heater, or any part of it.
The following should be also taken into
consideration:
10. The consumption of hot water is big
-
ger than the appliance’s capacity.
11. Weather conditions.
12. Huge consumption of hot water dur
-
ing the night.
13. The customer didn’t understand the
use of the electric resistance.
14. Customer’s expectations about the
performance of the system.
If your solar water heater continues not
to supply hot water, contact your local
distributor.
B. IF THE SOLAR
WATER HEATER
DOESN’T SUPPLY
HOT WATER WITH
THE ELECTRIC
RESISTANCE
1. Turn off the power supply and remove
the resistance’s cover.
2. Check the safety thermal switch F
on the thermostat, which has to be
pushed in.
3. Check the wiring between the thermo
-
stat and the electric resistance.
4. Check if the thermostat is adjusted in
a lower temperature than the desired
one.
5. Check the resistance for any damage
6. Check the main power supply.
7. Turn the power supply on and check
if the electric wires are properly con
-
nected to the relevant poles of the
resistance.
A certified electrician must do all the
electrical connections and checkings.
REPLACEMENT OF THE
MAGNESIUM ROD
To replace the magnesium rod:
1. Turn the power supply off.
2. Empty the water from the storage
tank.
3. Unscrew the bronze plug (09B), and
remove the magnesium rod
4. Fix the new rod on the bronze cup,
and re-screw it on the tube (09A) using
oakum for its water tightness.
5. Turn on the water supply and ensure
that it is completely water tight.
6. When the storage tank is completely
filled, turn on the main power supply.
notes:
An authorized distributor must do the
replacement of the magnesium rod.
The time of the replacement, of the mag
-
nesium rod, depends on the quality of
the water.
It is recommended that in areas where
total dissolved solids (TDS) is up to
600ppm, the magnesium rod must be
replaced every 5 years.
In regions where the TDS is more than
600ppm, the magnesium rod must be
replaced every 3 years.
In regions where the TDS is more than
1000ppm, the magnesium rod must be
replaced every 2 years.
In areas where the total dissolved solids
(TDS) is more than 600ppm it is neces
-
sary to install a filter
