4. Operation
4.1 Check items before test operation
4.1.1 Check items related to the electrical system
(1) Check that the fan is correctly wired.
(2) Check that the terminals are securely connected.
(3) Check that the fan is securely grounded.
(4) Check that the setup value of the overload protection device is consistent with the rated current
value of the motor.
Warning
Do not use the product at any voltage other than the rated voltage.
Otherwise, a fire or an electric shock may occur.
4.1.2 Check items related to the pump
Caution
Do not run the pump with its side plates and strainer removed. Failure to
observe this may cause an injury or breakage.
Caution
Do not allow a large amount of foreign matter in the pump section. Failure
to observe this may cause breakage of the sliding parts (e.g. bearings) in
the pump, leakage or unusual noise.
(1) Ensure that the oil level in the tank (oil tank) is above the "lowest oil
level" position.
Caution
Never run the pump idling (operation with oil level being lower than the
lowest oil level) during test operation. Also do not run the pump dry for
more than 30 sec. Failure to observe this may seize up the sliding parts in
the pump.
(2) Check the rotational direction. Normal rotational direction is
counterclockwise rotation when viewed from the motor side. (See the
right figure.)
(3) Rotate the pump shaft by hand to check smooth rotation. To turn the
pump by hand, remove the side plates and then grasp and turn its shaft.
If the rotation is stiff or not uniform, there may be some rusting or foreign
matter inside the pump. Inspect the pump in such a case.
(4) After the rotation by hand, fit the side plates.
Warning
Before rotating the pump shaft by hand to check it, be sure
to turn off the main power. Sudden operation of the pump
may cause an accident.
