AirLite will not be used for an extended time.
Note: Increases in back pressure in sampling condition due to buildup on fi lter
can decrease battery life.
Note: For maximum run time, insert new batteries in pump before sampling.

the compartment door. Remove the existing ba eries and
replace with new ba eries (see ba ery polarity below). Once the

Setting or Verifying the Flow Rate
For High Flow Sampling (1000 to 3000 ml/min)
Ensure pump has run for 5 minutes before calibrating. Using
1/4-inch ID tubing, connect a representative sampling medium to
the pump inlet (Figure 1, #4). Connect a calibrator to the inlet of
the sampling medium.
Turn on the pump using the On/Off bu on (Figure 1, #8). To adjust
the fl ow, turn the fl ow adjustment screw (Figure 1, #6) clockwise to
increase the fl ow or counterclockwise to decrease the fl ow until the
desired fl ow rate is indicated on the fl owmeter. When the desired
fl ow is obtained, take three readings to confi rm that the fl ow rate
is consistent. Calculate and record the fl ow rate as the average of
three readings.
Disconnect the calibrator and replace the representative sampling
medium with a new unexposed medium for sample collection.

Setting or Verifying the Flow Rate
For Low Flow Sampling (5 to 500 ml/min)
(Requires optional Constant Pressure Controller (CPC) and Adjustable Low Flow
Tube Holders - see Low Flow Adapter Kit in Optional Accessories.) See Figure 2.
Ensure pump has run for 5 minutes before calibrating.
The Constant Pressure Controller (CPC) accessory, Cat. No. 22426CPC-10, is used as a pressure regulator to maintain a constant
10 inches water back pressure for low fl ow sampling. The CPC is
used in conjunction with an Adjustable Low Flow Tube Holder
(Cat. Nos. 224-26-01, -02, -03, or -04) for single or multiple-tube
sampling.
Set the fl ow rate at ap-
proximately 1.5 L/min.
(See Se ing Flow Rate
for High Flow Sampling,
page 7.) For multiple-
tube sampling, the
fl ow rate must be
greater than the sum
of the required fl ow
rates through all the
tubes.

Label all tubes and ports. Insert opened representative tubes into
the rubber sleeves of each port on the Adjustable Low Flow Tube
Holder. If any port remains unused, place an unopened tube in it; it
is important to “seal” unused ports.
Use tubing to connect the exposed end of one tube to a primary
standard fl owmeter. Loosen the screw on the low fl ow holder port.
Turn on the pump using the On/Off bu on (Figure 1, #8), and calibrate
fl ow. Turn the brass screw (needle valve) on the Adjustable Low Flow
Tube Holder (Figure 2) until the fl owmeter matches the desired fl ow
rate. For multiple-tube sampling, repeat this procedure for each port
to calibrate the fl ow rate for each tube. Seal unused ports.
Do not adjust the fl ow on the pump. Adjust fl ow by using the brass
screw on the Adjustable Low Flow Tube Holder.

Turn off the pump. Disconnect the calibrator and replace the
representative tubes with new unexposed media for sampling.
Caution: Do not operate AirLite in hazardous or explosive
locations. AirLite is designed for applications that do not require
intrinsic safety.

Caution: Failure to follow warnings or cautions voids any
warranty.
Note: The CPC has two small inlet ports on the bottom of the unit.
These ports should be periodically inspected for blockage, which
can occur when sampling in dusty environments. Blocked ports may
cause back pressure to increase. Clean ports with a small pick and
use air to blow away particles.

Sampling
Caution: Do not operate AirLite in hazardous or explosive
locations. AirLite is designed for applications that do not require
intrinsic safety.
Caution: Protect sample pump from weather when in use
outdoors.
Caution: Before use, allow pump to equilibrate after moving it
from one temperature extreme to another.
Calibrate the sample pump for the
desired fl ow rate (see Se ing or Verifying
the Flow Rate, pages 7 & 8). Attach
the pump to a worker’s belt and the
sampling medium to the worker’s collar
(near the breathing zone). Turn on the
pump. Record the start time and any
other pertinent data. Monitor pump
and ba ery status by observing the LED
(see Reading the LED below). At the end
of the sampling period, record the stop
time. Cap the sample and send it with
pertinent sampling information to a
laboratory for analysis.
Clip sampling medium to
worker and pump to belt.
Reading the LED
The LED on top of the pump case (Figure 1, #7) indicates pump
and ba ery status.

Flow Fault Detection
(Pumps are shipped with fl ow fault enabled).
If the pump is unable to compensate for > 10 seconds due
to excessive back pressure, the pump enters fl ow fault. The
motor will stop and the LED will fl ash quickly. The auto-
restart feature will a empt to restart the pump a er 10
seconds. If back pressure is not corrected for an additional 10
seconds, the pump will a empt a second restart. The pump
will continue restart a empts every 10 seconds for a total
of fi ve times. If restart a empts are unsuccessful, the pump
will shutdown and the LED will fl ash four times every six
seconds. If the excessive back pressure is removed within the
fi ve restart a empts, the pump will run normally.
Note: The pump must be running without fault for at least 20
seconds for the auto-restart feature to be reset to fi ve tries.
Disabling the Fault Shutdown and Auto-restart
Features
If the fault link is fi ed when the pump
is initially switched on, the LED will
display a quick double fl ash before
running. If the link is not fi ed, the
pump will immediately run without
the LED fl ashing.
To disable the fault shutdown and autorestart features, remove the two screws
from the belt clip and set the clip and
screws aside. Remove the single screw
from the back of the pump case. Gently
remove the top of the pump case by
sliding it up and off . Using a pair of
tweezers, grip and pull off the program
connect link located on the board just
below where the motor wires connect
to the board. Reassemble the pump
and operate. The pump LED will indicate a fl ow fault by
fl ashing quickly, but the pump will no longer shutdown
during a fl ow fault. To restore fl ow fault shutdown and
auto-restart features, replace the program connect link.
Tip: For easy storage of link, simply place the link on one
pin only as shown above right.
