Programming a Hold at the Beginning of the Agitate/Wash-In Operation
To program a Hold status at the beginning of the Agitate/Wash-In operation for a
given cycle, do not program a valve for that cycle.
When the Agitate/Wash-In operation with no valve programmed is reached, the
HOLD light illuminates, the centrifuge stops, the primary audible alarm sounds (if
turned on), the secondary audible alarm sounds, and the MINIMUM AGITATE
TIME timer is temporarily suspended.
You have the following options:
• Program the desired valve to open. Press the CONTINUE button. The
centrifuge agitates, the selected valve opens, and the Agitate/Wash-In
operation continues as programmed.
-or-
• Do not program a valve to open. Press the CONTINUE button. The
centrifuge agitates, and the Agitate/Wash-In operation continues as
programmed without processing/wash solution being added.
