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 Chart C-l
(Appendix I).
Install level controls per the manufacturer's
recommendations included with the controls.
INSTALLATION OF UNIT IN PIT
Installation must be done with care to avoid damage
and insure proper operation.
1. Check clearance between the unit and pit. There
must be at least 1/2 inch (13 mm) clearance
between the sides of the pumping unit and any
portion of the pit. There should be 5.50 to 7.50
inches (140 to 190 mm) from the bottom of the
pump to the bottom of the pit. Check pump
dimension print for the distance pertaining to
your pump.
2. Guide the assembled pump carefully into pit so
that it does not strike the sides.
3. Once mounting plate (189) is supported on the
pit, shim under mounting plate where necessary
to level unit. Pump must hang vertically to avoid
placing a bending stress on the unit. Bolt
mounting plate to the supports on the pit.
4. Check for free turning. lf shaft (122) does not
turn freely, misadjustment of the discharge pipe
collar (242) may be placing a bending moment
on the column pipe assembly (192), causing the
shaft to bind or rub. lf that occurs, follow the
steps listed below.
a. Loosen set screws (222J). Gently raise or
lower discharge pipe assembly (195) while
rotating shaft (122) by hand in a clockwise
direction until shaft turns freely.
b. Tighten set screws (222J).
