Wear disposable, clean, lint-free nylon or powder-free surgical gloves to
handle the media cartridge.
Ensure pump has run for 5 minutes
before calibrating. Ensure rain
cover is removed from inlet and
that sampling head is completely
assembled with a media cartridge
(see Inserting a Media Cartridge
into the Sampling Head).
Thread calibration adapter into sampling head inlet.
Set and calibrate pump
fl
ow rate to 10 L/min (see Leland
Legacy Quick Guide). Record the pre-sample
fl
ow rate. See
pump and calibrator operating instructions.

Use provided short length of calibration tubing to connect inlet of calibration
adapter to outlet of a calibrator to form a calibration train.
Unscrew quick-connect plug on side of case. Use tubing with quick-connect
fi
tt
ing to a
tt
ach case (pump) inlet to exhaust of sampling head.
Ensure O-ring is installed on the quick-connect
