IMPORTANT DIRECTIONS
Before starting the assembly of the solar heater, take into account the following directions :
- The solar heater should be placed in a way that its collector see the south (in the northern hemisphere) or see the north (in the southern hemisphere),
- The place, that you will place the solar heater, must not be shaded and should be as near as possible to consumption,
- During works, the collectors should be covered from the sun to prevent any damage on the closed loop of the system,
- During the set-up, first fill the tank with the domestic cold water before filling the solar circuit with the antifreeze/water mixture (at least 15% antifreeze),
- The anti-freezing and anti-corrosive liquid delivered should be added to the closed loop after it has been diluted with water. Concentration must fit to the place,
- As temperature of over 60°C occur in the system a suitable domestic hot water mixing valve must be used on the domestic hot water side to avoid scalding.
SPECIFICATIONS:
The thermosyphon system comprises the following components: solar tank, collector(s), frame and installation kit (a detailed listing may be found below)
The maximum operating pressure on the domestic hot water side is 6 bars. A pressure reducer is recommended in the event that the domestic hot water pressure
is higher. The maximum pressure in the closed solar circuit is 1,5 bars. The solar tank is enamelled on the inside and equipped with two sacrificial magnesium
anodes to inhibit corrosion. 1,2 propylene glycol is used to provide frost and corrosion protection in the solar circuit.
PACKAGING AND TRANSPORT:
The system is packed in such a way as to prevent damages as far as possible. The products must be stored away from effects of the weather.
The packaging must be removed if the products are temporarily stored outdoors.
INSTALLATION GUIDELINES:
Before installing the system, ensure that the mounting surface (roof surface) will withstand the weight of the thermosyphon system when filled. Written confirmation
must be obtained from the architect/designer. The system must be installed at least 1m from walls or at the end of the roof to assist with maintenance of the system.
The piping must be sealed with a suitable roof insertion to prevent moisture getting in the roof. Precise guideline must also be provided by the architect for this.
All connection pipes must be very well insulated and UV resistant. The correct insulating material and insulation thickness must be selected according to local
conditions.
FRAMES:
The roof construction must be capable of withstanding the appropriate wind and snow loads. (1m³ powder snow = 60kg, 1m³ wet snow = 300kg).
The local conditions for snow and wind loads must be taken into consideration when mounting the system. Please consult local dealers for further information.
SAFETY EQUIPMENT:
A pressure relief valve with an opening pressure of 1,5 bars is used in the solar circuit. This valve is mounted on the tank in a ½ inch sleeve. The pressure relief
valve for domestic hot water is also installed in ½ inch sleeve above the tank.The solar pressure relief valve can also be fed through the overflow hose into a
container to trap the glycol.
WARNING: the collector should be covered before and during filling.
