1. Safety instructions
1.2 Intended use
Appropriate use in heating and domestic water systems in accordance with the applicable DIN standards. Installing and operating the assembly 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 Commissioning
Before commissioning, 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 trained experts and be recorded in writing. The
setting values must also be recorded in writing. The technical documentation must remain with the unit.
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 acci-
dentally). 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 oper-
ating 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.
