The Waste Level Sense uses air pressure to detect the liquid
level in the common waste container. If using individual
containers, use the waste level sense to detect the level of the
Diverter Valve waste container. Under normal operating
conditions it will fill faster than the Inject Valve waste
container. Empty both containers at the same time to prevent
overfilling the unmonitored container.
Accessory package (P/N 60-5239-006) includes parts to
complete the waste connections. Figure 2-3 shows the
recommended connections for user-supplied waste containers
with either a 38 or 45 mm opening (GL 38 or GL 45). Note that
there are two different styles that can ship with the system.
One styles includes a metal plate (Figure 2-3), the other has a
plastic plate with four small openings on the cap (Figure 2-4).
Refer to the steps in section 2.4 to connect the tubing to the
system using the compression fittings. Then, complete the
connections according to Figure 2-3 or 2-4.
If your connection hardware matches Figure 2-3, connect the
Waste Level Sense line to the compression fitting in the center
of the cap. Push the ends of the two black waste lines through
the holes in the cap.
If your connection hardware matches Figure 2-4, push the
three tubes through the cap. Push the stop on the Waste Level
Sense tubing against the cap. This ensures that the Waste
Level Sense tubing is far enough into the container to detect
when it is nearly full.
Should the container not have a GL 38 or GL 45 opening, omit
the use of the waste cap. Ensure the solvent tubes are secured
so they drain into the waste container. Secure the Waste Level
Sense air tubing so its outlet is at least two inches (5 cm)
below the container's maximum level.
Note
When using higher-density solvents such as dichloromethane
(DCM), ensure that the waste container is no more than 3 feet
below the supply solvent levels. Placing solvent containers above
the system and waste containers on the floor may cause the
internal check valves to open and allow solvent to flow through the
system when in the standby state.
