Rolling out shelves
The PC2200 and PC3200 models have roll-out shelves to provide easier access to agitators.
!
WARNING:
On PC3200 models, do not roll out more than one shelf at a time if they have
agitators on them. Having more than one shelf open at a time may cause the
incubator to roll forward and cause injury.

Storing items in the built-in agitator
NOTE:
This section only applies to PC4200 models, which have a built-in agitator. For
information about loading platelet bags in a Helmer agitator that is installed in
the incubator, refer to the Flatbed Platelet Agitator Operation Manual for your
agitator.
!
WARNING:
Follow all chemical handling and disposal requirements and procedures specified
by your organization. For more information, see Section 1, “Working safely.”
Before storing items in the incubator, be sure that the temperature is correct and stable. If you are using the
incubator for the first time, or after a power failure that causes the chamber to reach room temperature, let
the incubator stabilize at the setpoint temperature before storing items in it. Stabilization may take as long
as 30 minutes.
