1.2 Safety instructions
Please follow these safety instructions faithfully to eliminate hazards, personal injury and material damage. The installation,
commissioning, inspection, maintenance and servicing may only be performed by an approved, specialist company.
Please familiarise yourself with all the parts and their handling before starting work. Observe the applicable accident prevention
regulations, environmental regulations and legislation for the assembly, installation and operation of the system. In addition,
observe the applicable safety provisions of the DIN, EN, EVGW, VDI and VDE and all relevant country-specific standards, laws
and guidelines.
When working on the system: Disconnect the system from the mains and monitor it 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 from being opened accidentally). Repairs to components with a safety function
are not permitted. The installation location must be dry and frost proof. Hazards resulting from adjacent components must be
avoided. Free access must be ensured.
1.3 Intended use
The components listed in the following instructions are intended for use in heating systems according to
DIN EN 12828. The Fülly is only intended for the monitored refilling of heating water during the bleeding procedure. Bleeding
the heating system causes the system pressure to drop. If this is lower than the pressure set in the Fülly, the flow is turned on
and the lack of pressure is balanced out by the refilling of the water.
