Cleaning the heating system

Choose cleaning intervals according to the degree of soiling in the system itself.
Cleaning the screen insert and dirt/magnetite separators
1. Depressurise the heating circuit in the area of the dirt trap.
2. Unscrew the screening chamber.
3. Remove and clean the screen insert.
4. Re-assembly the components in reverse order.
!
NOTICE! Ensure that the screen insert is installed correctly and the connection is tight.
Flushing the system
The ingress of oxygen into the heating water circuit may result in the formation of oxidation products (rust), particularly if
steel components are used. These enter the heating system via the valves, the circulating pumps and/or plastic pipes.
Particularly for the piping, diffusion-proof installation must therefore be ensured.
Residue from lubricants and sealants may also contaminate the heating water. If the contamination is so severe that the
performance of the liquefier in the heat pump is reduced, the system must be cleaned by a specialist installation
company.
• Based on current information, cleaning using a 5% phosphoric acid solution is recommended. If cleaning needs to
be performed more frequently, a 5% formic acid solution should be used.
• The cleaning fluid should be at room temperature.
• We recommend flushing the heat exchanger in the direction opposite to the normal flow direction.
• We recommend connecting the flushing device directly to the feed and return for the liquefier in the heat pump to
prevent acidic cleaning agent getting into the heating system circuit.
• Then re-flush thoroughly with suitable neutralising agents to prevent damage caused by any cleaning agent residue
remaining in the system.
!
NOTICE! Handle acids with care. Always observe the trade association regulations and the cleaning agent
manufacturer's specifications.
9.2

Cleaning the air system

• Under extreme weather conditions (e.g. snow drifts), ice may form on the air intake and air outlet grating in
individual cases. Clear the air intake and air outlet area of ice and snow to ensure the minimum air flow.
• Remove any twigs, leaves and dirt accumulated around the device at regular intervals.
• Clean the evaporator, ventilator and condensate drain of contamination (leaves, twigs, etc.) as required.
Removing the gratings on the front and rear
• If necessary, open the inspection cover to clean the condensate drain or the condensate hose.
