6.5 Voltage stabilizer
The following freezer models are equipped with a built-in voltage stabilizer:
• Innova U535, 120 V and 208 - 230 V, 60 Hz
• Innova U725, 208 - 230 V, 60 Hz
• Innova C585, 120 V and 208 - 230 V, 60 Hz
• Innova C760, 208 - 230 V, 60 Hz
The built-in voltage stabilizer automatically compensates for variations in the supply voltage (in
case of over-voltage, brown-outs, dips, sags and surges). The output is only switched if the
power disturbance is sustained for at least two seconds.
The U101 freezer has the option of an external voltage stabilizer.
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 LED
NORMAL 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.
