CAUTION:
In case of connecting some units to the same water piping, design the water piping so that the water distribution to each unit
is equal (refer to gure below) Imbalance of water distribution may cause a serious damage like a water freezing in the heat-
exchanger.
6.3. Minimum internal system water volume
To ensure the cooling operation at least 5 minutes without interruption, the internal chilled water volume in the piping
system should be greater than the minimum volume as shown below.
NOTE:
Minimum internal system water volume written above is for standard ON/OFF differential, minimum internal system water volume
shall be increased by the setting of differential.
