Operation
The voltage stabilizer unit indication is displayed on the lower right front panel
of the upright freezers and on the front panel above the air filter on the chest
freezers.
When you switch the freezer on, if the input voltage is within the specified
range, the green
NORMAL
LED will illuminate. If the voltage stays within the
specified range, the green LED will remain illuminated.
Sustained variations in the input power will be automatically compensated for
by the stabilizer circuit and indicated by a red LED for
HIGH
VOLTAGE
or an
amber LED for
LOW VOLTAGE
