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.

1. Basics
1.4 Functions
1 Constant pressure position
Automatic refilling of the heating water to the adjustable
system pressure.
2 Filter
An integrated filter prevents larger foreign particles from
entering the heating system.
3 Check valve
Prevents the heating water from flowing in the reverse
direction when there is insufficient fill pressure.
4 System separation
Via hose connection with terminal.

2. Installation and operation
2.1 Installation
1. Establish a rigid connection (which is capable of being shut
off) between the heating system and the ½“ female thread
of the Fülly. Ensure free access to the pressure adjuster and
the filter. Sufficiently secure the connecting line.
2. Establish a hose connection between the filling water source
(which is capable of being shut off) and hose connector of
the Fülly. The hose should be long enough to be disassem-
bled easily once the heating system has been filled (system
separation).
2.2 Operation
1. The Fülly is set to approx. 1.5 bar in the factory. If a lower system pressure is desired, rotate the slotted screw in the centre
of the plastic housing approx. 4 times counter clockwise.
2. Slowly open the shut-off on the filling water side. Check the set pressure on the manometer. (The pressure in the replenish-
ment system must be greater than the system pressure.). To increase the filling pressure, rotate the slotted screw below the
„1.5 bar“ sticker clockwise.
3. Slowly open the shut-off on the heating water side. This lowers the pressure on the Fülly manometer and filling water is
replenished until the setpoint value is reached.
4. Bleed the pipework. Meanwhile, the Fülly will automatically refill to the set value.
5. Close the boiler-side and filling-water-side shut-offs and release the hose connection on the Fülly.
2.3 Operation
Please note the application limits:
•Permissible media: Heating water (in accordance with VDI 2035, non-corrosive), max. glycol content: 50%
•Max. permissible pressure of filling water: 10 bar
•Max. permissible pressure of heating system: 6 bar (manometer)
•Permissible temperature: 0-70°C / Room temperature 5°C to 70°C (non-condensing)
2.4 Maintenance
Clean the filter as required in a depressurised state. Remove the filter insert by unscrewing the plastic stopper (SW17) and clean it
with a soft brush. We recommend performing regular leak-tightness tests.
