Seasonal Shutdown
The following services should be performed when the unit is to be
shutdown for a prolonged period:
1. Drain the cold water sump and all piping that will be exposed to
freezing temperatures.
2. Clean and ush the cold water sump with the sump strainers in
place. Leave the drain open so rain and melting snow will drain from
the unit.
3. Clean the sump strainers and re-install.
4. Lubricate the fan shaft and motor bearings, motor base and motor
base adjusting screw.
5. Close shut-off valve in water make-up line and drain all exposed
make-up piping.
6. Inspect the protective nish on the unit. Clean and renish as
required.

weather operation and consult your B.A.C. representative about
protection against coil freezing.
