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 heating system.
While the System is heating up, water will leak out of the safety valve.
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. Decalcification at regular intervals may be
necessary in highly calcareous water areas.
Attention – only valid for heating tanks with hot water supply.
A chemical decalcification can be carried out by a specialist using an approved decalcifier and taking the appropriate
precautions.
1.
The safety valve protects the tank against excess pressure. The functional capacity must be checked at regular intervals
by venting. If an expansion vessel is used, the safety valve is not, or only rarely, required. Over a longer period of time
therefore, it can become blocked and not function when needed.
2.
If there is a danger of freezing, the DHW tank should be permanently heated or completely emptied.
3.
A damp cloth is sufficient to clean the outer parts. Please avoid using any abrasive or solvent cleaning.
