up, so it is highly recommended to add alcohol and propanol mixture in chilled water. Do not cut o󰀨 the
power supply when the unit is turned o󰀨, otherwise the freeze protection does not work. Alternatively,
cut o󰀨 the power supply and drain the water system thoroughly.
(8) When the unit runs under the low load requirement, in order to avoid low load protection which would
a󰀨ect the service life of the unit, make sure the water capacity is more than 1/6 of total rated ow rate
per hour of each module. If necessary, a water tank will be installed.
(9) Note: never use salt mixture to prevent the unit from being corroded.
