Routine Maintenance

Freedom HW Unit

Minimal maintenance is required to keep your Freedom HW operating
properly. Periodically you should:
• Clean the exterior of the unit with a damp cloth to prevent the
accumulation of dust and dirt.
• Ensure that the DC cables are secure and fasteners are tight.
• Make sure the ventilation openings are not clogged.

Batteries

When possible, you should recharge your batteries whenever a low
voltage warning or a shutdown occurs with the Freedom HW. This gives
the batteries a much longer life than recharging when the batteries have
been almost completely discharged.
