Getting Started Insert/Replace the Batteries The AirLite with Timer is powered by three standard AA alkaline batteries located in a compartment on the bottom of the pump (Figure 1). To insert new or replace existing batteries: Use a slotted screwdriver to loosen the screw on the bottom of the case (Figure 1). Open and remove the compartment door.
Operation High Flow Applications (1000 to 3000 ml/min) Set/Calibrate Flow Rate Do not operate pump in hazardous or explosive locations. AirLite with Timer is designed for applications that do not require intrinsic safety. • Allow pump to equilibrate after moving it from one temperature extreme to another. Turn on the pump using the on/off button (Figure 1) and run for 5 minutes before calibrating.

Set Up/Sample • Allow pump to equilibrate after moving it from one temperature extreme to another. • Protect sample pump from weather when sampling outdoors. • Do not operate the pump in hazardous or explosive locations. AirLite with Timer is designed for applications that do not require intrinsic safety.

Low Flow Applications (5 to 500 ml/min) • Single-tube sampling requires the All-in-One Adjustable Tube Holder; see the operating instructions for the All-in-One for details on its operation. • Multiple-tube sampling requires a Constant Pressure Controller (CPC) and a Dual, Tri, or Quad Adjustable Low Flow Tube Holder accessory; see the operating instructions for the CPC and Adjustable Low Flow Tube Holder for details on their operation.

Set Up/Sample with Single Tube Do not operate AirLite with Timer in hazardous or explosive locations. Pump is designed for applications that do not require intrinsic safety. • For maximum run time insert new batteries in pump before each sampling period. If using rechargeable AA 1.2-volt NiMH batteries, expect approximately half the run time stated for disposable batteries.
