5.3.2 Battery
Replacement
The 6.0v Cyclon battery is mounted within the compressor housing, near the
interface board.
This is located (a) behind the lefthand base cover on the upright freezers, or (b)
in the compressor housing on the chest freezers.
WARNING!
Use only a replacement battery of the correct type and proper part
number. The battery must be fitted so the terminals correspond to
the polarity labels on the electrical panel.
To replace the battery:
1.
Turn off (
O
)
the power switch and disconnect the power supply.
2.
Remove the side cover and the screws that secure the battery to the housing
panel.
3.
Disconnect the battery terminals.
4.
Be certain, when connecting the new battery, to respect the correct polarity
(red is + positive and black is – negative).
5.
Reinstall the battery fixing screws and the side cover.
6.
Reconnect the freezer to the power supply and turn the power switch on (

).
