WARNING:
Before carrying out any work on the pumps or control unit, these devices must be deenergised in
accordance with the guidelines.
1.2 Intended use
For use in heating systems in accordance with DIN EN 12828.
Installing and operating the devices incorrectly will invalidate any warranty claims. The shut-off valves may only be closed
by an authorised specialist when servicing, otherwise the safety valves will not work.
Caution:
Do not make any changes to the electrical components, the design of the system or the hydraulic components!
This would adversely impact on the safe function of the system.
1.3 Initial start-up
Before the initial start-up the system should be checked for leak tightness, correct hydraulic connection and accurate and
correct electrical connections. It is also necessary to flush the system thoroughly or as required. Commissioning must be
performed by qualified specialist personnel and be recorded in writing. The setting values must also be recorded in writing.
The technical documentation must remain with the device.
1.4 When working on the system
The system must be disconnected from the mains and monitored to ensure that no voltage is being supplied (e.g. at the
separate cut-out or a main switch). Secure the system against being restarted. (With gas-fuelled systems, close the gas
shut-off valve and secure it to prevent it being opened accidentally.) Repairs to components with a safety function are not
permitted.
1.5 Liability
We reserve all copyrights for this document. Misuse, in particular the reproduction or disclosure to third parties is
prohibited.
These installation and operating instructions must be given to the customer. The technical team carrying out the work (e.g.
installer) must clearly explain to the customer how the unit works and operates.
