Operation
High Flow Applications (1000 to 3000 ml/min)
Setup
Ensure pump is
not
running. Fully charge the battery by connecting the charger plug to
the sampler charging jack (Figure 1, #15). Use only an SKC charger designated for this
model.
CAUTION: DO NOT CHARGE OR OPERATE PUMP FROM CHARGER
IN HAZARDOUS LOCATIONS. Charge in fresh air only.
Using
fl
exible tubing,
connect the sampling media to the pump intake (Figure 1, #6). Ensure the battery is fully
charged and the pump is set for high
fl
ow before calibrating and sampling. (
See Return to
High Flow, page 6.
)
After charging the battery pack, it is good practice to run the pump for approxi-
mately 5 minutes before calibrating. This ensures the battery is in more steady-state
conditions and improves the agreement in pre and post-sampling calibrations.
Use only an SKC-approved charger designated for this model to ensure
reliable performance. Failure to do so voids any warranty.
Ensure proper orientation of charging cable before plugging it into the
charging jack. Improper orientation/contact will short-circuit the battery
and voids any warranty.
Short-circuiting the battery pack will render it immediately inoperative.
Failure to follow warnings and cautions voids any warranty.
Setting the Flow Rate
Before use, allow pump to equilibrate after moving it from one
temperature extreme to another.
Remove the tamper-resistant cover. Ensure pump has run for 5 minutes before
proceeding with calibration. Connect a calibrator to the intake of the sampling media
using
fl
exible tubing. Start the pump using the ON/OFF switch (Figure 1, #1). Set the
fl
ow rate using the FLOW ADJUSTMENT SCREW (Figure 1, #4). When the
fl
ow rate
is set, use the ON/OFF switch to turn off the pump. Disconnect the calibrator. Replace
the medium used for calibration with a new unexposed medium for sample collection.
