8.3 Quantity of Water in Installation
Model
Minimum water volume (L)
If the total water volume in the system is less than the value in the table above, the additional water tank is
necessary in order to avoid the compressor On/Off frequency.
The minimum size of the water tank is calculated as:
Size of additional water tank(L)=Minimum water volume (L) –Actual water volume(L)
