Solar Energy Heating Systems Manufacturer Solar Water Heater Collectors and Solar Panels

10a. INSTRUCTIONS AFTER THE INSTALLATION

	The solar water heater reaches the optimum performance two days after the installation. During these two days, it is recommended to avoid hot water consumption, even if there is sunshine.
	Check every year the level of the fluid in the closed circuit. Use only the thermal fluid SOLATHERM to fill it.
	In regions with too much dust, we recommend you to clean the glass of the collector with water, every two months in order to remove the dust from the glass, unless there is enough rain.
	In case of a glass damage, replace the glass immediately to avoid further damage of the collector.
	For all water heaters, the main principles 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, the nuts, the plates, the moly plugs, the screw nuts and the support plates, for looseness or any damages, especially when the appliance 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.

10b. 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 circuit and fill it, if necessary (see instructions).
3.	Check the connection tubes (05) and (18) to ensure that they are not bended 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 a 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 collector's connections are properly made and are fully watertight.
9.	Ensure that there is no obstacle (building, tree etc.) shading the solar water heater, or a part of it.
The following should be also taken into consideration:
10.	The consumption of hot water is bigger than the appliance's capacity.
11.	Weather conditions.
12.	Huge consumption of hot water during 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 in the thermostat, which has to be pushed in.
3.	Check the wiring between the thermostat 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 connected to the relevant poles of the resistance.
A certified electrician must do all the electrical connections and checkings.

10c. 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.
Note: An authorized distributor must do the replacement of the magnesium rod. The time of the replacement, of the magnesium 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.
