HYDROMATIC LIQUIDATOR 2 HP GRINDER PUMP
Models: SPGW200M2-2, SPGW200M3-2
OPERATION
Starting the pump
To start the pump, perform the following steps in order:
1.
If the motor is three phase, the rotation of the impeller must first be checked. With the pump removed from the
basin and lying on its side with the inlet in view, quickly turn the pump on and then off.
WARNING: Keep hands and clothing away from cutter elements at all times.
The impeller should turn counterclockwise when viewed from the suction inlet opening. If the rotation is
wrong, turn off the main breaker and interchange any two line leads to the motor in the control panel to correct
the rotation.
If the pump is piped in permanently and the inlet cannot be observed, rotation will have to be checked by pump
operation described later.
If pump is single phase, not rotation check is necessary.
2.
Run water into sump until motor is covered.
3.
Open valve in discharge line.
4.
Turn pump on. If the pump runs and the water does not pump down, stop the pump and close the valve in the
discharge line. Lift the pump until the sealing flange just clears the sealing face to allow trapped air to be
vented. Lower the pump to its normal operating position, open the discharge valve, and start the pump.
(If the pump is pipes in permanently it may be necessary to loosen the union at the pump discharge to vent
trapped air.)
5.
If the pump is three phase, and it is piped in permanently, and still does not operate properly after venting,
rotation is wrong and can be reversed by interchanging two line leads. (See 1 above.)
6.
The level controls should be set so that the pump turns off when the liquid level is approximately two inches
above the inlet and turns on when the level is approximately two inches above the top of the motor.
NOTE: All wire connections should be made by a qualified electrician. All local wiring codes must be
observed. Be sure ground wire is connected to a good ground such as a water pipe per NEC and local codes.
