Operating Lever
The operating lever is a multiple function, bar-shaped lever located at the front left side of
the instrument, near the top. The three positions of the lever are labeled and their related
functions are as follows:
•
UNLOCK
releases the pressure of the reagent pump arms against the pump tubing.
•
LOCK
locks the reagent pump arms into their proper position against the pump tubing.
•
PRIME
provides an override control to allow the pumps to run continuously so the tubes
can be primed with solutions and cleared of air bubbles. The lever must be held
continuously in the
PRIME
position. When released, it returns automatically to the
LOCK
position.
