Operating and storage conditions
Note: To comply with CSA standards, the pump must be installed and used indoors, and within the operating
conditions specified in Table 1 below.
2.2
Performance
Note: Where total pressures are shown in Table 2 below, measurements were taken using an untrapped total
pressure capacitance diaphragm gauge on a header, as specified by Pneurop standards.
