The accessory package 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).
Refer to the steps in section 2.4 to connect the tubing to the
system using the compression fittings. Then, complete the
connections (refer to Figure 2-3):
1. Push the three tubes through the cap. The tubing will fit
snugly in the cap and may require some force.
2. Push the Waste Level Sense tubing until the Tubing Stop
is against the cap. This ensures that the outlet is about two
inches (5 cm) below the container’s maximum level.
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. Seal the container
opening to avoid solvent vapors.
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.
