Operation
High Flow Applications (750-5000 ml/min)
Setup
Fully charge the battery by connecting the charger plug to the sampler charging jack
(Figure 1, #18). Use only an SKC charger designated for this model. CAUTION: DO
NOT CHARGE IN A HAZARDOUS ENVIRONMENT. Using flexible tubing,
connect the sampling media to the pump intake (Figure 1, #9). Make sure the pump is
set for high flow. (See “Return to High Flow” p. 4).
Setting the Flow Rate
Test the battery pack by turning the sampler on using the ON/OFF switch (Figure 1,
#4). Press the START/HOLD key then the FLOW AND BATTERY CHECK key.
Adjust the flow to 2 L/min using the FLOW ADJUST SCREW (Figure 1, #7). The LCD
should indicate “BATT OK” in the upper left corner, if not, recharge the battery. Press
the FLOW AND BATTERY CHECK key to place the pump in “HOLD” mode.
Connect a flowmeter to the intake of the sampling media using flexible tubing. [For
pressure applications, insert the exhaust port fitting into the exhaust port (Figure 1,
#15) and connect the sample bag to this fitting.] Press the FLOW AND BATTERY
CHECK key to start the pump and set the flow rate using the FLOW ADJUST SCREW
(Figure 1, #7). When the flow rate is set, press the FLOW AND BATTERY CHECK key
to place the pump in “HOLD”.
Caution: When using impingers, place an in-line trap between the pump and the
impinger to protect the sampler from liquid or vapors. FAILURE TO USE THE
IMPINGER TRAP VOIDS THE WARRANTY. The impinger and trap may be
mounted to the sampler using the accessory mounting screws (Figure 1, #8).
Sampling
For personal sampling, clip the sample collection media to the worker in the breathing zone. While the LCD shows “HOLD,” start the test cycle by pressing the START/
HOLD key at the beginning of the desired sampling period. “SAMPLE RUNNING”
will display. Record the start time. The time display will automatically track the
sampling period time elapsed.
User options during sampling:
Pause - pause (shutdown) by pressing the START/HOLD key. All timing data will
freeze. To resume sampling press the START/HOLD key, timing data will resume.
Fault shutdown - during restricted flow or low battery conditions the sampler will
shut down. “HOLD” will display on the LCD and timing functions will pause. “LO
BATT” or “FLOW FAULT” will display on the LCD depending on the cause of the
shutdown. To restart a pump in “FLOW FAULT,” correct the flow blockage and press
the START/HOLD key. A pump displaying “LO BATT” must be recharged before
sampling.

Low Flow Applications (5-500 ml/min)
Setup
Fully charge the battery by connecting the charger plug to the sampler charging jack
(Figure 1, #18). Use only an SKC charger designated for this model. CAUTION: DO
NOT CHARGE IN A HAZARDOUS ENVIRONMENT.
Test the battery pack by turning the sampler on using the ON/OFF switch (Figure 1, #4). Press
the START/HOLD key then the FLOW AND BATTERY CHECK key and adjust the flow to 1.5
L/min using the FLOW ADJUST SCREW (Figure 1, #7). If performing multiple sampling using
an adjustable flow tube holder (dual, tri, or quad), the flow rate of the pump must be greater
than the sum of the flow rates through the tubes; the flow rate through any one tube cannot
exceed 500 ml/min. The LCD should indicate “BATT OK” in the upper left corner. If not,
recharge the battery. Press the FLOW AND BATTERY CHECK key to place the pump in
“HOLD”.
Remove the screw cap (Figure 1, # 14) covering the regulator isolation valve. Turn the
exposed screw 4-5 turns counterclockwise. Replace the screw cap. The pump is now
set for low flow. Connect an adjustable low flow holder (Figure 2) to the pump intake
(Figure 1, #9) using flexible tubing. Insert an opened sorbent tube into the rubber sleeve of
the low flow holder so the arrow on the tube points toward the holder.
Caution! Long duration color detector tubes require a special tube cover which
accommodates an in-line trap tube. The trap tube protects the pump from caustic
fumes which are often released from detector tubes. FAILURE TO USE THE TRAP
TUBE VOIDS THE WARRANTY.
Setting the Flow Rate
Connect a flowmeter to the exposed end of the sorbent tube. Loosen the screw on the low
flow holder, for Tri and Quad models first rotate the anti-tamper cover (Figure 2, #1) to
expose the brass screw(s) (Figure 2, #2). Activate the pump by pressing the FLOW AND
BATTERY CHECK key and adjust the flow rate by turning the brass screw until the
flowmeter indicates the desired flow. Do not adjust the flow on the pump. Adjust the flow
only by using the brass screw (Figure 2, #2) on the low flow holder.
When the flow rate is set, place the pump in “HOLD” by pressing the FLOW AND
BATTERY CHECK key and disconnect the flowmeter. Replace the sorbent tube used
for setting the flow with a new sorbent tube for sample collection. Place the appropriate size tube cover (Figure 2, #5) over the tube, and screw it in place on the low flow
holder.

Sampling
For personal sampling, clip the sample collection media to the worker in the breathing zone. While the LCD shows “HOLD,” start the test cycle by pressing the START/
HOLD key at the beginning of the desired sampling period. “SAMPLE RUNNING”
will display. Record the start time. The time display will automatically track the
sampling period time elapsed.
User options during sampling:
Pause - pause (shutdown) by pressing the START/HOLD key. All timing data will
freeze. To resume sampling press the START/HOLD key, timing data will resume.
Fault shutdown - during restricted flow or low battery conditions the sampler will
shut down. “HOLD” will display on the LCD and timing functions will pause. “LO
BATT” or “FLOW FAULT” will display on the LCD depending on the cause of the
shutdown. To restart a pump in “FLOW FAULT,” correct the flow blockage and press
the START/HOLD key. A pump displaying “LO BATT” must be recharged before
sampling.
Return to High Flow
To return to High Flow, remove the screw cap (Figure 1, # 14) covering the regulator
isolation valve. Turn the exposed screw clockwise until it stops. (Do not over-tighten.)
Replace the screw cap. The pump is now set for high flow.
Bag Sampling by Positive Pressure
Using flexible tubing, connect the sampling media to the pump intake (Figure 1,#9).
[For sample bags using positive pressure filling, insert the exhaust fitting into the
exhaust port (Figure 1, #15). After setting the flow rate, you will connect the sample
bag to this fitting instead.]

Preventive Maintenance
Battery Pack Maintenance
Removal—Remove the two screws (Figure 1, #16) which secure the battery pack
(Figure 1, #17) and loosen the four case screws above and below the belt clip.
Carefully slide the battery pack out from under the belt clip (Figure 1, #19) being
careful to keep it straight.
Replacement—Slip the front edge of the battery pack (Figure 1, #17) under the belt
clip (Figure 1, #19) and rotate the battery pack so the rails engage the slots on the case
front. Push the battery pack until it is properly located. Reinstall battery screws and
tighten the case screws (Figure 1, #16).
Charge Maintenance
For proper maintenance of battery packs, SKC produces an optional cycling charger
(Catalog No. 223-426) which discharges and recharges the battery automatically to
protect against memory effects.
Rotate the use of any spare pack to avoid idle periods in excess of one month. Fully
charge packs before or after use or storage.
SKC UL listed battery packs (SKC Catalog No. P21661) contain a protective device to
eliminate potential short circuiting while the pump is in use. If the indicator light on
the charger will not light while charging, either the battery pack, charger, or wall
outlet is inoperative. If you are unable to determine which is inoperative, please
contact SKC Technical Support at 724-941-9701 or e-mail [email protected]
Caution: Do not charge in a hazardous environment.
Warning: Using a non-approved charger voids the SKC warranty.
Warning: Tampering with the battery pack voids the SKC warranty
and the UL Intrinsic Safety listing.
Pump Inlet Filter
The SKC sampler is fitted with a filter/trap inside the clear plastic intake port
housing. This prevents particulates from being drawn into the pump mechanism.
Occasionally, the filter should be visually checked to assure that it does not become
clogged. If maintenance is necessary:
1. Clean all dust and debris from around the filter housing.
2. Remove the four screws (Figure 1, #10) and the front filter housing.
3. Remove and discard the filter membrane (Figure 1, #12) and O-ring (Figure 1, #11).
4. Clean the filter housing.
7
5. Insert a new filter membrane and o-ring.
(Filter Replacement Kit, SKC Catalog No. P22409)
6. Reattach the front filter housing and cross-tighten the four screws.
