To commission the fans for the first time, the following actions have to be taken:
•
Check by hand if the fan wheel is turning freely.
•
Check that all dampers are open in the right way (see chapter 5.2 and 5.3)
•
Check if the duct system is clean and not blocked by any parts.

If a frost thermostat is installed, check if it is set to the correct temperature. The factory
setting is +8°C.
5.6 Cooling circuit DanX 1/2/3 HP
When starting the compressor of the cooling circuit for the first time, let the compressor run
for about 5 minutes and then check the sight glass of the cooling circuit to see if there is
enough refrigerant in the unit (no bubbles). If refrigerant is missing, stop the compressor at
once and check for a leakage.
