5 Installation
All pipes connecting to the tank should have removable connections (fitting/flange). Pipe thread seals with teflon are to
be avoided.
All tank connecting pipes are to be planned, constructed and tested according to the technical rules in force, as well as to the
corresponding norms and regulations in accordance with their application and supply medium.
Sensors and thermostats necessary for temperature control must be securely and permanently positioned on the tank
(immersion sleeve and sensor rail).
T
he tank’s venting and draining facilities must have the appropriate dimensions and be correctly installed.
The installation company is responsible for the correct execution of work and for the safe and careful insulation of the pipes.
All factory-made, non-insulated surfaces must be insulated in a professional manner on site.
6 Commissioning
Before putting into operation, the entire system should be flushed through. Particles in the system compromise the
operating reliability.
Fill the heating system slowly with water and vent all the air.
Start-up the system.
Before the handover of the system to the end user/owner, the plumbing contractor should ensure that the
system is tested to full load, controls are set and that pipe work and connections are without leaks.
Afterwards,
the end user has to be instructed in the operation and handling of the tank, as well as the system. The instruction
must to be documented in the installation and maintenance record.
Please note that the operation and lifetime of the system depend decisively on a regular maintenance.
7 Maintenance and wear parts
Regular maintenance increases the lifetime and operation reliability of the system.
A damp cloth is sufficient to clean the outer parts. Please avoid using any abrasive or solvent cleaning.
8 Recycling and disposal
The products are specified and manufactured according to VDI 2243. The products are mechanically separable and 100%
recyclable. Make sure that the components are disposed according to the relevant regulations.
