Basin Heater (Optional)
One or more electric immersion heaters prevent the basin from completely freezing over and damaging the unit during
shutdown or standby. The heaters are sized for the specific unit. The heating element has an enclosure that is suitable for
outdoor use. Annually, inspect the basin heater prior to the risk of reaching freezing operating conditions.
Operation
Ensure that the heating element is completely submerged before energizing the main disconnect. For installations that have a
BAC Controls Enclosure, please consult the submittal packet provided with the unit and contact your local BAC Representative
for support. For installations that use a stand alone BAC heater control panel, see below.
NOTICE: The basin heater is not designed to prevent icing during unit operation.
