Warnings
• Use the AC power source as the primary power source. Battery is used as an auxiliary power source when the AC
power source cannot be used sufficiently, such as during transportation, electric failure, etc. If the battery is depleted
and charging is insufficient, the Controller will not be able to operate by the battery during an emergency such as electric
failure.
• Connect the AC power cable to the AC power inlet of the Controller until you hear a click. Subsequently, check that the AC
power lamp in the control panel of the Controller is lit. If the connection is insufficient, the Controller will be powered by the
battery. And therefore the battery will be depleted, the devices will shut down and circulation will not be maintained.
• When the Low Battery Alarm or the Battery Empty Alarm is issued, immediately connect the Controller to the AC power
source.
• Do not store the battery in a discharge status. Storing the battery left in a discharge status may cause degradation,
resulting in making the battery unavailable in emergency situations.
