WARNINGS: Turn drive off before removing or installing tubing. Fingers
or loose clothing could be caught in the rollers.
Periodically examine bearings and moving parts for excessive wear that can cause overheating of surfaces from friction.
Select tubing for chemical compatibility. Ground or
electrically bond containers during fluid transfer to avoid
electrostatic charge buildup that can ignite vapors when
discharged. Refer to NFPA 77.
ATEX Ratin g: The models are rated as Group II, Category 3 (Zone 2) equipment
