3000 System – Instruction Manual – Version 1.364
When the priming button is pressed, the green light in the priming button
goes on, the three pumps start rotating and fluid is delivered through the
pump tubing as long as the pump tubing release knob is in the lock position,
see Pump tubing release knob on page 4-6. When the priming button is
pressed again, the green light in the priming button goes off and the three
pumps stop rotating.
Priming of the pump tubing ensures that fluid is cleared of air bubbles.
Pump tubing release knob The pump tubing release knob is located next to the priming button on the
left side of the system, see Figure 4-6.
The pump tubing release knob has two positions:
• Lock position: The pump arms press the stain, buffer, and rinse tubes
against the pumps.
• Unlock position: The pressure of the pump arms against the stain,
buffer, and rinse tubes is released.
Sensing switch fingers The sensing switch fingers are three finger-like devices located just above
the rear edge of the platen.
When a sensing switch finger is contacted, the respective sensing switch is
activated, which signals that a glass slide is in position for the pump to run.
After a specific time delay, the pump motor for the specific fluid is activated.
The pumps are set so that precise volumes of stain, buffer, and rinse are
delivered to their respective areas on the platen, see Platen on page 4-8.
Each fluid is delivered through its respective cannula and tube to the platen
orifice. The capillary space between the glass slide and the platen is then
filled with the measured volume of fluid.
Waste tank The waste tank is located underneath the platen and collects used and
overflow fluids. The waste tank can be pulled out from the front of the slide
stainer. When installed properly, the waste tank front is flush with the front
plate of the slide stainer.
