AirLite Quick Start Guide
On/Off
1. Lift control cover on top of pump.
2. Press On/Off button.
Setting Flow Rate (1000 to 3000 ml/min)
1. Set up sampling train.
2. Connect calibrator to inlet of sample medium.
3. Turn on pump and adjust flow adjustment screw on pump until

Caution: To prevent corrosion of battery terminals, remove batteries when
AirLite will not be used for an extended time.
Note: Increases in back pressure in sampling condition due to buildup on filter
can decrease battery life.
Note: For maximum run time, insert new batteries in pump before sampling.
Note: If using rechargeable AA 1.2-volt NiMH batteries, run time will be
approximately half that stated for disposable batteries.

Changing the Batteries
The AirLite is powered by three standard AA alkaline batteries
located in a compartment on the bottom of the pump (Figure 1, #1).
1
To change the batteries, use a slotted screwdriver to loosen the
screw on the bottom of the case (Figure 1, #2). Open and remove
the compartment door. Remove the existing batteries and
replace with new batteries (see battery polarity below). Once the
new batteries are in place, insert the hinge (Figure 1, #3) on the
compartment door under the lip of the case, close the door, and
tighten the screw until secure.

Polarity of Batteries
Important: Note the polarity of the batteries.
Note: For maximum run time, insert new batteries in pump before sampling. If using rechargeable AA 1.2-volt NiMH batteries, expect
approximately half the run time stated for disposable batteries.
Note: To prevent corrosion of battery terminals, remove batteries when
AirLite will not be used for an extended time.

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 button (Figure 1, #8). To adjust
the flow, turn the flow adjustment screw (Figure 1, #6) clockwise to
increase the flow or counterclockwise to decrease the flow until the
desired flow rate is indicated on the flowmeter. When the desired
flow is obtained, take three readings to confirm that the flow rate
is consistent. Calculate and record the flow 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 flow 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.
2
cont’d
Set the flow rate at approximately 1.5 L/min.
(See Setting Flow Rate
for High Flow Sampling,
page 7.) For multipletube sampling, the
flow rate must be
greater than the sum
of the required flow
rates through all the
tubes.

With a short length

(marked “to sample”)
to the Adjustable Low

Configuration for Low Flow Sampling
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 flowmeter. Loosen the screw on the low flow holder port.
Turn on the pump using the On/Off button (Figure 1, #8), and calibrate
flow. Turn the brass screw (needle valve) on the Adjustable Low Flow
Tube Holder (Figure 2) until the flowmeter matches the desired flow
rate. For multiple-tube sampling, repeat this procedure for each port
to calibrate the flow rate for each tube. Seal unused ports.
Do not adjust the flow on the pump. Adjust flow 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.
3
Calibrate the sample pump for the
desired flow rate (see Setting 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 battery 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 battery status.
Slow flash ..................... Normal run
Fast flash ....................... Flow fault
Double flash ................ Low battery, approximately one-hour
run time remaining
Flash every
eight seconds ............... Pump shutdown due to
exhausted batteries
Four flashes every
six seconds ................... Pump shutdown due to flow fault
Note: Indication of pump shutdown due to exhausted batteries will
override all other indicators.

Flow Fault Detection
(Pumps are shipped with flow fault enabled).
If the pump is unable to compensate for > 10 seconds due
to excessive back pressure, the pump enters flow fault. The
motor will stop and the LED will flash quickly. The autorestart feature will attempt to restart the pump after 10
seconds. If back pressure is not corrected for an additional 10
seconds, the pump will attempt a second restart. The pump
will continue restart attempts every 10 seconds for a total
of five times. If restart attempts are unsuccessful, the pump
will shutdown and the LED will flash four times every six
seconds. If the excessive back pressure is removed within the
five restart attempts, the pump will run normally.
3
cont’d
Note: The pump must be running without fault for at least 20
seconds for the auto-restart feature to be reset to five tries.
Disabling the Fault Shutdown and Auto-restart
Features
If the fault link is fitted when the pump
is initially switched on, the LED will
display a quick double flash before
running. If the link is not fitted, the
pump will immediately run without
the LED flashing.
Link fitted
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 Link stored
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 flow fault by
flashing quickly, but the pump will no longer shutdown
during a flow fault. To restore flow 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.
