4 Installation
4.1 Pre-installation
Precautions
WARNING:
•When installing in a potentially explosive environment, ensure that the motor is properly
certified.
• All equipment being installed must be properly grounded to prevent unexpected dis-
charge. Discharge can cause equipment damage, electric shock, and result in serious in-
jury. Test the ground lead to verify it is connected correctly.
NOTICE:
•Electrical connections must be made by certified electricians in compliance with all inter-
national, national, state and local regulations.
• Supervision by an authorized ITT representative is recommended to ensure proper instal-
lation. Improper installation may result in equipment damage or decreased performance.
4.2 Location
Pumping unit should be placed as close as practical to the source of supply. Floor space and head room
allotted to the unit must be sufficient for inspection and maintenance. Be sure to allow for crane or hoist
service. On horizontatly split case pumps, always allow sufficient head room to remove the upper half
casing
4.3 Install Close-Coupled and Vertical Pumps
1. Close Coupled
a) A "close-coupled" pump may be mounted horizontally or in a vertical position provided motor is
above pump.
b) The unit should be bolted to a concrete foundation or an adequately supported structure, sub-
stantial enough to absorb any vibration and to form a permanent rigid support for the unit.
All units have holddown bolt holes in the motor feet and pump/ adapter feet. Depending upon the
motor frame, the pump or adapter feet may be higher or lower than the motor feet.
c) Shim as required, then bolt all feet securely to support or foundation.
Since the pump is mounted on the motor, permanent alignment is "built in''. No subsequent align-
ment is necessary.
2. Vertical
a) Vertical pumps may be mounted directly on a pit, using either the pump support plate only or in
conjunction with a pit or tank cover.
The units are shipped completely assembled except for motor, pit cover (if any), and float controls.
b) Check all bolts and nuts on the entire unit to make sure they are securely tightened.
c) Connect float and controls as shown in sectional view at 8.3 Parts List on page 74.
3. Installation must be done with care to avoid damage and insure proper operation. It is recommend-
ed that a man be stationed inside the pit, whenever possible, to assist in the initial installation.
4 Installation
16 3175 Installation, Operation and Maintenance Instructions

4. Lower the assembled pump (less motor) carefully into the pit. Guide unit carefully so that it does not
strike sides of pit. When unit is in place, level the support plate. Shim under support plate as re-
quired. Pump must hang perfectly vertical to avoid placing a bending stress on the unit.
5. The support plate should be bolted to an adequately supported structure, substantial enough to ab-
sorb any vibration and to form a permanent, rigid support for the unit.
6. Place motor on motor support and tighten bolts (with lode washers) snugly.
7. Check for alignment by laying a straight edge across coupling hubs at four points 90° apart. See
image below. When the straight edge rests evenly at all four points, the coupling is aligned.
NOTICE:
Alignment of the coupling is of extreme importance for trouble-free mechanical operation.
1. Coupling cover 2. Straight edge
Figure 9: Coupling Alignment
8. The machined faces of the motor support and motor will provide angular alignment. However, any
foreign material or burrs on the surface will destroy this alignment. Make sure surfaces are clean
and smooth.
4.4 Install Horizontal Pumps
Bed plate mounted units are normally mounted on a concrete foundation of liberal thickness poured on a
solid footing, using a one-three-five mix. The foundation should be substantial in order to absorb any vi-
bration and to form a permanent, rigid support for the pumping unit.
1. The location and size of foundation bolts are shown on the outline assembly drawing supplied for
the unit.
2. When unit is mounted on a concrete foundation, each foundation bolt should be installed with a pipe
sleeve around it to allow for adjustment.

The I. D. of the sleeve should be 2 1/2 - 3 times the bolt diameter.
b) Stuff waste around bolts to prevent concrete from entering between bolt and sleeve. Bolts
should be of sufficient length so that they project through the nuts approximately 1/4" after al-
lowance has been made for grouting, bedplate thickness, and nut thickness.
NOTICE:
Remove all dirt from the mounting pads in order to ensure that the correct leveling is achieved.
Failure to do so can result in equipment damage or decreased performance.
3. Put the unit in place on wedges. The wedges should be placed at four points as shown in the image
below. Some long installations may require additional wedges near the middle of the bedplate.
