• Ensure that no foreign objects can be drawn into the
pump.
• 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.
• Direction of rotation of pumps with three phase
motor: Pumps wired ready for connection with three
phase motor are supplied with a mains plug. The elec-
trical wiring is laid out for a right-handed rotary field.
Checking the direction of rotation:
The three phase socket has to be checked, and if nec-
essary corrected, by an electrician. Otherwise the per-
formance of the pump might be reduced.
Make sure ventilation is adequate to maintain recommend-
ed operating temperature. Keep a minimum distance of
2 in (5 cm) between the cooling fan (underside the pump)
and surrounding items (e.g., housing, walls, etc.), or else
install an external automatic ventilation system. Do not
place the pump on soft surfaces (e.g., rubber foam) dur-
ing operation. This may reduce or block the fans’ air sup-
ply. Check fan regularly for dust/dirt. Clean fan guard grill
if necessary to avoid a reduction of ventilation.
Use only hoses at the inlet and outlet of the pump with
an inner diameter at least as large as the diameter of the
pump’s tubing (to avoid overpressure at the outlet, and
reduction of pumping speed at the inlet).
Assemble silencer or hose nozzle at the outlet of the pump.
Allow the equipment to equilibrate to ambient temperature
if you bring it from cold environment into a room prior to
operation. Notice if there is water condensation on cold
surfaces.
Comply with all applicable and relevant safety require-
ments (regulations and guidelines). Implement the re-
quired actions and adopt suitable safety measures.
