instruction manuals for other precautions concerning storage of individual components of pumping unit. Fresh lubricant should be applied to bearings upon removal of equipment from storage. SECTION 3 INSTALLATION Location: Several factors should be considered when selecting a location for the pumping unit (pump and drive). -
Page 7: Wiring And Controls
To check coupling alignment, the following procedure should be followed: Set the coupling gap to the dimension shown on the coupling data sheet. Check for parallel misalignment by placing a straight edge across both coupling halves at four points 90° apart. Correct alignment occurs when the straight edge is level across the coupling halves at all points. -
Page 8: Operation
The motor ratings stamped on the motor nameplate must match the line voltage and wire capacity. DO NOT USE ANY OTHER VOLTAGE. SECTION 4 OPERATION Do not exceed the rated working pressure of the pump. The sum of the suction pressure and the maximum pump operating head (converted to units of pressure) must be less than the pump working pressure, at all times. -

vacuum pump or ejector operated by air, steam, water, etc. to evacuate air from the pump case and suction line by connecting the ejector to the priming connection on top of the pump case. Check direction of rotation before starting pump. Rotation should be the same as the direction arrow on the case. - Page 10 Mechanical seals should be replaced if they are leaking. Refer to the motor manufacturer’s instructions for periodic maintenance requirements. Check that electrical control equipment contacts are in good condition and clean.
