Page 43: During Operation
page 43 of 72 During operation ➨ Vent and dispose of potentially dangerous gases or vapors at the outlet of the pump appropriately. + Due to the high compression ratio, the pump might generate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust tubing or exhaust valve) at the outlet. - Page 44 page 44 of 72 Do not start the pump if the pressure difference between NOTICE inlet and outlet ports exceeds max. 16.0 psi (1.1 bar). Attempts to start the pump at higher pressure difference may cause stalling and damage of the motor. Prevent internal condensation, transfer of liq- condensate / dust uids or dust.
