Pump Installation
‐ Before installation, check your local electrical and plumbing regulations. These regulations
are for your safety.
‐ Use the pump dimensional drawing to ensure proper installation.
‐ Make sure the cables are not kinked or nipped.
‐ Ensure that hoses, tubes and valves are suitable for the pressure of the pump. Place the
pump on a flat base and make sure it cannot fall over or sink.
‐ Make sure that the pump cannot rotate at the startup or during operation.
‐ Make sure that the impeller rotation is correct.
‐ Should there be any problems occurred during installation, please get in touch with a
PRORIL representative.
‐ DO NOT dismantle the product before/during installation without any authorized
instructions from PRORIL
.
‐ Make sure the pump is on a firm and stable surface and
cannot roll or fall over.
‐ Check the direction of rotation.
• The correct starting rotation of the pump is counter-
clockwise (seen from above).
• If the direction of rotation is incorrect,two of the wires
should be switched (consult a certified electrician).
NEVER hold the handle while checking the direction of rotation. The starting jerk may be
very violent.
WARNING! Changing the direction of rotation on a plug connection without phase shifter
can only be performed by a certified electrician.
ATTENTION! If the built-in motor safety is activated, the pump will shut down and restart
automatically as soon as the motor has cooled down.
WARNING: if you need to work on the pump,make sure that it is isolated from the power
supply and cannot be energized.
