Table 1. Pump Run Time in Hours with Alkaline Batteries
Following are typical run times achieved when using new AA Alkaline
batteries. Data is sorted by type of sample media. All run times are listed in
hours.
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.

6
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).
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. 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.
Important: Note the polarity of the batteries.
Note: For maximum run time, insert new batteries in pump before
sampling.
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)
Using 1/4-inch ID tubing, connect a representative sampling me-
dium to the pump inlet (Figure 1, #4). Connect an external flowme-
ter 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 flowmeter 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 on p. 12.) See Figure 2.
The Constant Pressure Controller (CPC), Catalog No. 224-
26CPC-10, is an accessory for the AirLite that 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 (Catalog No. 224-26-
01, 02, 03, or 04) for single or for multiple tube sampling.
Set the AirLite flow rate at approximately 1.5 L/min. (See
Setting Flow Rate for
High Flow Sampling,
page 7.) For multi-
tube sampling, the
flow rate setting of
the pump must be
greater than the sum
of the required flow
rates through all the
tubes.
With a
1
/ 2 - to 1-inch
length of Tygon tubing,
connect the pump inlet to
the CPC outlet (the side
of the CPC without a
label), (Figure 2).
Connect the inlet side of
the CPC (marked “to
sample”) to the Adjust-
able Low Flow Tube
Holder (Figure 2).
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 ports remain unused, place unopened tubes
in them; it is important to “seal” the unused ports.
Use tubing to connect the exposed end of one tube to a primary
standard flowmeter. Turn on the pump using the on/off button
(Figure 1, #8), and calibrate flow to a primary standard. Turn
the flow adjustment screw (needle valve) on the Adjustable Low
Flow Tube Holder (Figure 2) until the flowmeter matches the
desired flow rate. For multi-tube sampling, repeat this proce-
dure for each port to calibrate the flow rate for each tube. Seal
any unused ports.
Do not adjust the flow on the pump. Adjust flow by using the brass
screw on the Low Flow Tube Holder.

Sampling
Calibrate the sample pump for the de-
sired flow rate (see Setting or Verifying
the Flow Rate, pages 7 & 8). Attach the
pump to a worker’s belt and the sam-
pling medium to the worker’s collar
(near the breathing zone). Turn on the
pump. Record the start time and any
othernecessarydata.Monitorpumpand
battery status by observing the LED (see
Reading the LED below). At the end of the
samplingperiod,recordtheendingtime.
Cap the sample and send it along with
pertinent sampling information to a
laboratory for analysis.
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.
Turn off the pump. Disconnect the flowmeter and replace the
representative tubes with new unexposed media for sampling.
Caution: Long-duration Color Detector Tubes require a special
tube cover that accommodates an in-line trap tube. The trap
tube protects the pump from caustic fumes that are often
released from detector tubes. Please read closely all precau-
tions when using these tubes.
Failure to use the necessary traps will damage the pump and
void the 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.

Flow Fault Detection
(Pumps are shipped with flow fault enabled.)
If pump flow is blocked for 10 seconds or more, the pump
motor will stop and the LED will flash quickly. The auto-
restart feature will attempt to restart the pump after 10
seconds. If the fault continues, it will attempt a second
restart after ten seconds. It will continue for a total of five
restart attempts. If none are successful, the pump will
shutdown and the LED will flash four times every six
seconds. If the flow fault is removed within the five restart
attempts, 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 five tries.
Disabling the Fault Indicator and Auto-restart Feature
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.
To disable the fault shutdown and
auto-restart feature, 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 flow fault by
flashing quickly, but the pump will no longer switch
off. 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.
