Securing water storage12. InstallationMinimum water storage• If the length of water pipe is too short, water storage within the system becomes lower and ON/OFF operationof the compressor occurs more often. For stable operation, maintain certain water storage by applying headeror Buffer tank.CAUTION• The product should be operated for 3 minutes after it has stopped to protect water side heat exchanger(plate type heat exchanger) from freezing.• If total water storage becomes under the minimum storage, install another tank to retain more water storage.- In case of variable flow system, retain certain amount of water by bypass pipe system.• Total water storage in the system = water storage within the water pipe + water storage in DVM CHILLER + waterstorage in AHU (or fan coil)• Minimum capacity of buffer tank = Minimum water storage - Total water storage in the system excluding buffer tank• Select the capacity of buffer tank according to system installation condition of the field.• Water amount within the DVM CHILLER: 3.17 galNOTEConnecting water pipeCompanion coupling is not supplied.
