Thanks to the adapter piece of the aerosol spray can, FPA can be added to the system by means of a dirt separator. To do this, proceed as follows:
! Switch off the circulation pump!
1. Drain the water from the dirt separator to remove any sediment.
2. Unscrew the hose connector of the dirt separator and tighten the spray can with the adapter piece. Open the drain tap of the dirt separator again.
3. Add FPA by pressing the button. The entire contents of the spray can are emptied in approximately twenty seconds.
4. Let the water circulate according to the schedule in the paragraph ‘Dosage’.
5. Drain the dirt via the dirt separator until clean water is obtained. Dispose of the waste water in accordance with the applicable regulations.
6. Fill in the label on the cap of the spray can and apply it to the heat pump.
