LOCATION OF UNIT
Vertical sump pumps are to be mounted directly in a
sump or tank, with proper support under the polyester
mounting plate (189). Floor space and head room allotted
to the unit must be sufficient for removal from the sump
or tank.
PREPARATION FOR INSTALLATION
Vertical units are shipped completely assembled except
for level controls and motors. Make sure all bolts are
securely tightened. Use a torque wrench on all
non-metallic joints. Bolt and nut torque values should not
exceed those shown in the chart in Appendix I. Install level controls per the manufacturer's
recommendations included with the controls.
INSTALLATION OF UNIT IN PIT
1. Inspect pump and any accessories packed with the
unit to assure no damage has occurred during transit.
NOTE: Motors are shipped separately and should
also be inspected.
Install the pump assembly in the pit before mounting
the motor to prevent damage.
$
CAUTION
When handling the pump unit, it is very important
to pick up the unit by the top to prevent damage to
the pump.
2. A rope or sling should be attached to the bearing
pedestal (108) or the mounting plate (189). Serious
damage may result if the unit is picked up by the
column shaft (192) or discharge pipe (195). The
pump assembly must be lowered carefully into the
pit. Care must be taken to guide the pump as it is
lowered into the pit to avoid striking the sides.
3. When the mounting plate (189) is resting in the
proper position, check the level of the plate, and shim
if necessary to level the unit. The pump shaft must be
vertical to avoid a bending stress on the shaft column,
and to avoid bearing damage during operation. Check
the shaft column (192) with a level to be sure the unit
is straight and plumb.
4. Bolt down the mounting plate, and be sure it is
supported on all four sides.
NOTE: There should be a minimum of 4 to 12
inches between the bottom of the suction strainer
and the bottom of the tank of pit.
For higher flow pumps, this clearance may be
specified as greater; check your outline drawing.
