Page 12: Setting Up And Installing The Equipment
page 12 of 50 + Do not use the pump to generate pressure. + The pumps are designed for ambient temperatures during operation between +50°F and +104°F (+10°C and +40°C). Periodically check maximum tempera- tures if installing the pump in a cabinet or a housing. Make sure ventilation is adequate to maintain recom- mended operating temperature. - Page 13 page 13 of 50 + Keep the control line away from heated surfaces. • Provide a firm, level platform for the equipment. Check that the system which you are going to evacuate is mechanically stable. Check that all fittings are secure. Ensure a stable position of the pump without any me- chanical contact other than the pump feet.

page 16 of 50 pump chambers regularly and clean if necessary. • Consider interactions and chemical reactions of the pumped media. Ensure that the materials of the pump’s wetted parts are compatible with the pumped substances, see section „Technical data“, pg. 22. When changing the substances pumped, we recom- mend purging the pump with air or inert gas prior to changing the pumped media. - Page 17 page 17 of 50 + Make sure that the exhaust pipeline cannot become blocked. If there is an exhaust isolation valve, make sure that you cannot operate the equipment with the valve closed to avoid a risk of bursting! + Always provide a free and pressureless exhaust outlet to avoid damage to pump valves and risk of bursting.
