4. PUMP INSTALLATION

1) The pump have been evaluated for use with water or water based solutions. Please contact the
manufacturer for additional information.
2) Risk of electric shock. The pump models do not come with electric plug connectors. To reduce
the risk of electric shock, be certain that it is connected only to a properly grounded, grounding-type
receptacle.
3) Attach a rope or lifting chain (not included) to the handle (or lifting rings) on the top of the pump.
4) Do not lift the pump by the power cable or discharge hose/ piping. Proper lifting equipament
(rope/chain) must be used.
5) The pump are designed to operate fully or partially submerged. Avoid running the pump dry for
extended periods of time.
6) As a general rule, the top discharge pumps can pump down to a level above the suction screen.
Pumping lower than screen will permit air to enter the pump and cavitate, lose prime or become
air bound.
7) Running the pump dry for extended periods of time may damage the seals and over-heat the
motor.
8) Never place the pump on loose or soft ground. The pump may sink, preventing water from rea-
ching the impeller. Place on a solid surface or suspend the pump with a lifting rope/chain. The
pumps are provided with a suction.
9) Strainer to prevent large solids from clogging the impeller. Any spherical solids which pass
throug the strainer should pass through the pump.
10) For maximum pumping capacity, use the proper size non-collapsible hose or rigid piping. A
check valve may be installed after the discharge to prevent back flow when the pump is shut off.
ELECTRICAL
5. CONNECTIONS
1) The pump must be connected to terminals or starting equipment installed at a level at which it
cannot be flooded.
2) All electrical equipment must always be earthed (grounded). This applies both to the pump and
to any monitoring equipment.
3) The electrical installation must conform to national and local.
4) Check that the mains voltage and frequency agree with the particulars stamped on the motor
rating plate.
6. OPERATION
1) Before starting: Checking the direction of ration of the pump. At the instant of starting, the pump
will jerk anti-clockwise when viewed from above. If the direction of rotation is incorrect, transpose
two phases.
2) Reversal of the direction of rotation on a plug that has no phase transposing device may be don-
de only by authorized person.
3) If the built-in motor protection has tripped, the pump will stop but will restart automatically when
coocled down.
