- check the earth connections
- check for water and refrigerant leaks
- check operation and parameters with the commissioning
data
- clean the water fi lters

- check system pressure
- clean the outdoor unit heat exchanger
- clean the condensate trays
- Close the fi lter tight, in order to avoid water leakage.
- Install the base pan on the hydronic module with the
previously removed screws (only 80AW1/80AWT).
