DANGER
The ⅜ -in (9.6 mm)
DRAIN MUST BE VENTED TO ATMOSPHERE.
The
sample drain contains analysis wastes, which include both sample and
chemical reagents. Please check with local authorities concerning proper
disposal of waste from this product.
NOTES:
The enclosure drain produces no waste under normal use. However, in the
event of spills or leaks, some waste may be produced.
The analyzer is shipped with all of the internal tubing attached. Before
starting up the instrument, verify that the tubing lines are secured.
Installing Peristaltic Pump Head Tubing
Press the STOP key.
Disengage the U shape pressure plate of the pump head assembly by pressing with two fingers
and gently move upside as shown in Figure 6. Slide the tube fitting retainers at each side as
shown in Figure 5.
Replace the old tube by sliding off the barbed fitting. If necessary, clean the pump rollers.
Lubricate the tubing with a pea-sized quantity of silicone oil.
Fit the new tube and replace in the pressure plate. Note that the pressure plate sides must click
properly in the pump head assembly and align on both sides.
