| Question: | PCXR Series samplers: How are they used in low flow mode? |
| Answer: | Low flow applications on the PCXR Series require an adjustable low flow holder (224-26 Series):
- Turn the pump on and adjust the flow to approximately 1.5 L/min. (Attach nothing to the intake of the pump.)
- Remove the protective cap covering the regulator shut-off valve. (It is the small round screw on top of the pump.) Open the regulator shutoff valve by turning the adjustment screw 4-5 turns counterclockwise. Replace the protective cap.
- Connect an adjustable low flow holder to the filter housing intake.
- Insert an opened tube in the adjustable low flow holder's rubber sleeve and connect a flowmeter to the exposed end of the tube.
- Turn the pump on and turn the adjustment screw ON THE ADJUSTABLE FLOW HOLDER until the flowmeter displays the desired flow rate.
