Cleaning system with auxiliary pump
Use of the LF-M Meter
Directly filling via the ion exchanger is not suitable for surface heating systems that can only be de-aerated
through purging. The delivery rate is insufficient enough for purging air from a horizontal line. In these
cases, we recommend filling up with untreated water and subsequently demineralising using a cleaning
system.
This procedure is also suitable for subsequently demineralising systems with too much salt content accor-
ding to the boiler manufacturer's specifications or guidelines.
In doing so, the ion exchanger is integrated into the heating system circulation with the help of a separate
pump (e.g. jet pump, impeller pump, centrifugal pump) and two reinforced hoses. The type of adapter
used here is of less importance; instead, it is more important that the circulation pumps are operating and
all valves are open enabling the system water to be mixed thoroughly.
The temperature of the cartridge may be a maximum of 60 °C for a short period. It must be connec-
ted to a return line with the lowest possible temperature. Only hoses that are sufficiently pressure
and temperature resistant should be used (reinforced hoses). The work may only take place with
monitoring.
The pump must be connected behind the cartridge, no pump pressure on the cartridge!
General safety instructions
The resin from the cartridge must not enter the heating system. Before each use, the retention sieves
on both sides of the cartridge must be checked. The work with the cartridge may only take place with
monitoring.
It is recommended to do a test run of the system and purge the oxygen and carbon dioxide gases that
are normally present in tap water.
Run the cartridge until it is exhausted.
Determine the number or size of the
required cartridges based on the sys-
tem content and the capacity diagram
on page 2.
The adhesive label stick visibly to the
boiler.
Affix the correct fill-up.
The use of measuring devices makes
reliable system cleaning easier.
The LF-M meter enables flow rate and
water quality monitoring. The cartrid-
ge can be completely used up and
then replaced at the appropriate
time.
The cartridge can easily be used seve-
ral times with the LF-M meter for
smaller amounts of water until it is
exhausted.
