possibility of chilled water freezing in the evaporator tube. Please operate the cooling water pump
automatically by a signal from the chiller.
(2) If you operate the cooling water pump within 1 hour after the chiller stop, the chilled water pump will
operate automatically to prevent chilled water freezing. Caution labels are put on the control pane
of chiller and field supply panel.
(3) When the chiller is used for cooling and you want to operate the cooling water pump within 1 hour
after the chiller shutdown for preventing cooling water freezing, be sure to operate the chilled water
pump at the same time for preventing chilled water freezing.
