fore setting the voltage selection switch. Note: If the
pump is switched on with wrong voltage selection, the
motor may be damaged!
Make sure ventilation is adequate to maintain recommend-
ed operating temperature. Keep a minimum distance of
2 in (5 cm) between the cooling fan and surrounding items
(e.g., housing, walls, etc.), or else install an external au-
tomatic ventilation system. 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 fittings (to avoid overpressure at the outlet, and
reduction of pumping speed at the inlet).
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.
