Instructions For; Airflow Adjustment - VWR Pinocchio Super Petri Manual De Instrucciones

Overview
The Pinocchio Super II microbiological gas sampler is a portable instrument for determining the level of
existent microbiological contaminants in the compressed gas of aseptic manufacturing operations.
An official validation of the Pinocchio Super II air sampler is required as part of an inspection. The flow meter
should be calibrated by an official agency at regular intervals (usually every year). Official validation of the
flow meter can also be performed by VWR INTERNATIONAL customer support service.

3) Fully open the flow meter knob (pos. "C" Figure 1).
4) Fully close the D and D2 valves.
5) Fully open the D1 valve.
6) Open the line of compressed air or gas.
7) Start opening the D valve slightly, ensuring that the manometer is not indicating a pressure greater than 6
bar.
8) Open the D valve until you see the desired airflow on the flow meter, the suggest value is 100 l/min (210
SCFH). The purpose of this operation is to obtain a known volume of air, without contaminating the sampling
circuit.
