Close the ball valves and drain the water from the dirt separator. Add PAB to the installation using 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. Let the water circulate according to the schedule in the ‘dosage’ section. For very dirty installations, the cleaning time must even be extended to 1 week.
3. Drain the dirt via the dirt separator until clean water is obtained. Dispose of the waste water in accordance with the applicable regulations
4. Fill in the label on the cap of the PAB and attach it to the heat pump.
