Section 2 Preparation

2-11

If an optional waste cap is not used, ensure the waste lines 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.

2.8 Optional External Gas

The Torrent has an internal air pump that provides

compressed air for solvent and waste level sensing, and

column/cartridge purging. Optionally, the system can deliver a

compressed gas instead of air. Inert or other gases may be

more suitable than air for some applications.

If ambient air is compatible with your solvents and waste,

simply leave the GAS INLET port open.

If you want to use a gas instead of air, connect user-supplied

8" I.D. tubing to the GAS INLET port. Connect the other end

to the user-supplied compressed gas. The external compressed

gas should be dry, filtered, and regulated to 2–5 psi (0.14–0.34

atm, 13.8–34.5 kPa).

2.9 Connect and Route Drain Line

WARNING

Risk of fire or equipment damage. Failure to connect drain lines

may allow organic solvents to pool in unsafe areas, creating a

potential for dangerous levels of flammable vapors. Improper

draining may damage the instrument’s internal components.

The Torrent has a front-mounted drip tray. There is a drain

connection under the left side of the tray. Connect

user-supplied tubing to this drain and route it to a suitable

waste fluid collection container.
