AHP60 26/32 kW - Installation, Use and Maintenance
is any copper or aluminium, appropriate treatment is recommended to guarantee a long lifetime for
the unit. In most cases, this treatment involves adding chemical solution corrosion inhibitors to the
installation. We recommend contacting water treatment specialists.

Unit monitoring
If the recommendations listed above (new installation or renovation) have been followed, the unit
monitoring is limited to:
- Checking the amount of make-up water (fill water volume + make-up water volume < 3 times the
unit volume).
- Checking the pH level (stable or slightly increasing)
- Checking the water hardness (TH stable or slightly decreasing)
We recommend monitoring these parameters two to three times a year. It should be noted that the
"make up water quantity" parameter is vital for a long lifetime for the unit.
If any of these three above parameters deviates from the above recommendations, refer to a water
treatment specialist to correct the problem.
•
Setting up a plate exchanger
If the recommendations listed above cannot be met, you can set up a plate exchanger to separate
the primary system from the secondary system, which protects the heat pump from undesirable
effects.
•
Setting up a filtration system
A filtration system on the back of the heat pump is obligatory in order to remove suspended particles
from the unit.

We recommend connecting the safety valve vent to an appropriate conveyor

If not, the discharge water may build up around the machine and constitute a
slipping or falling risk.
