6. Maintenance
6.1. Maintenance and Shutting the System Down
Maintenance work may only be carried out by expert trained personnel. The Thermosiphon System must be regularly checked
and documented in accordance with the initial installation and maintenance checklist contained in the installation instructions. 6
The panel surface must be protected from direct sunlight during shutting-down, during maintenance work and when draining
the hot water storage tank. You must take particular care to ensure that the electrical lines are de-energised (electric immersion
heater). The service itself should be carried out in the morning if possible.
In order to be able to replace the electric immersion heater or to service the Mg anode, you must make sure that there is no hot
ter, until the storage tank temperature has dropped to the line temperature. (See hydraulic circuit diagram; Caution - Danger of
scalding!). The storage tank can then be drained by interrupting the process water infeed line and unscrewing the safety valve in
the process water circuit.
Careful Opening the Screwed Fittings - Storage Tank is Under Pressure!
Danger of injury and scalding!
The electric immersion heater, available as an option, may only be integrated in the Thermosiphon System by expert personnel.
6.3. Safety Instructions for Subsequent Installation of the Electric Immersion Heater
For subsequent installation of the electric immersion heater, you must make sure that the solar panel is protected from direct
sunlight and that the contents of the storage tank have been drained (Caution: Danger of scalding, system is under pressure).
