Compress 7001i/7400i AW AWE – 6721835320 (2021/09)
Fig. 6 AWE
[1] Particle filter
[2] Pressure gauge
4.1.1 Check system pressure
Check the pressure on the pressure gauge.
If the pressure is lower than 0.5 bar, slowly increase the pressure in
the heating system by adding water through the filling valve to a
maximum of 2 bar.
Contact your installer or reseller if you are insecure how to perform
the filling.
4.1.2 Particle filter
The filter prevents particles and contamination from entering the heat
pump. Over time, the filter can become blocked and must be cleaned.
To clean the filter, the system does not need to be emptied. The filter and
shut-off valve are integrated.
Cleaning the strainer
Close the valve (1).
Unscrew the cap (manually) (2).
Take out the strainer and clean it by running water over it or by
pressure cleaning.
Reinstall the strainer. For proper assembly, make sure that the guide
bumps fit into the recesses in the valve.
Fig. 7 Cleaning the strainer
Screw the cap back on (tighten handtight).
Open the valve (4).
Check the magnetite indicator
After installation and startup the magnetite indicator must be checked at
more frequent intervals. If a lot of magnetic dirt is clinging to the
magnetic bar in the particulate filter and that dirt frequently causes an
alarm related to the poor flow (e.g., low or poor flow, high flow supply or
HP alarm) an approved magnetite filter must be installed to avoid regular
draining of the indicator. The magnetic filter must be installed in addition
to the mesh filter and be placed in the secondary circuit after the
hydraulic separation. A filter also increases the longevity of components
in the heat pump as well as the remaining parts of the heating system.
When installing a magnetic filter, consideration should be made for the
product specific impact on the pressure drop on the system.
4.1.3 Overheating protection
Overheating protection is only available in indoor units with integrated
booster heater. The overheating protection has to be manually reset if it
is triggered.
To reset the overheating protection on AWE:
Contact the installer or dealer.
4.1.4 Pressure switch
The pressure switch and the overheat protection are connected in series,
triggered alarm or information in the controller means too low pressure
in the system or too high temperature in the booster heater.
If the pressure switch is released it resets itself when the pressure is
sufficient in the system.
