• Check the power source and the pump’s rating plate
to be sure that the power source and the equipment
match in voltage, phase, and frequency.
•
Pump with dual-voltage motor: Check that the volt-
age selection switch is positioned correctly. Check ev-
ery time before starting the pump.
Note: If the pump is switched on with wrong voltage
selection, the motor may be damaged!
Change the selection at the voltage selection
switch only, if the pump is unplugged from the
power source.
•
Direction of rotation of pumps with three-phase mo-
tors: Pumps with three-phase motors wired ready for
connection are supplied with a power plug (CEE). The
electrical wiring is laid out for a right-handed rotary
field.
Checking the direction of rotation:
Switch on pump for a few seconds and check if the
pump aspirates at inlet. If no suction occurs switch off
pump immediately. The three phase socket has to be
checked and if necessary corrected by an electrician.
• Use only oil of the recommended type. Other oils or
operating fluids may cause damage of the pump or
danger.
• Use
special oils (see “Oil change”, pg. 32) for the
for the
rotary vane pump, if, e.g.,
- acid vapors are pumped.
- extremely high aging stability is required.
- oxygen or other strong oxidizing agents are pumped.
• Take adequate precautions when handling pump flu-
ids, lubricants, and solvents. Use appropriate protec-
tive clothing, safety goggles and protective gloves to
avoid excessive contact with the skin and possible skin
irritations (including dermatitis).
• Comply with all relevant statutory requirements and
regulations concerning the handling, storage and dis-
posal of oil.
