General Information
• Before installation, read the following instructions
carefully. Each pump is individually factory tested to
assure proper performance. By closely following these
instructions, potential operating problems should be
eliminated, providing years of trouble-free service.
RISK OF ELECTRIC SHOCK. Always
disconnect the pump from the power
source before handling or making adjust-
ments.
• Always wear rubber boots when water is on the floor and
you must unplug the pump. Make sure the pump power
source is a separately fused, grounded 3-wire type
receptacle of 15 amp capacity. DO NOT REMOVE
GROUND PRONG OR PLUG. DO NOT USE AN
EXTENSION CORD. Check to make sure installation is
in accordance with the National Electric code and all
applicable local codes.
• Tools required for installation are a) pipe wrench, b)
regular screw driver, and c) hacksaw (for replacement or
removal of existing rigid piping.)
• DO NOT use pumps in water over 140
°
F.
• DO NOT drain hot water heaters into the sump pit
when servicing.
• DO NOT use pumps in mud, sand, cement, oil or
chemicals
• DO NOT modify the pumps in any way.
Sump Pit
1. A sump pit not less than 14" in diameter is
recommended. A larger diameter pit is preferred as it
allows for a longer pumping cycle and reduced switch
cycling.
2. If the pit is not already enclosed on the bottom, provide
a hard level bottom of bricks or concrete. DO NOT
place the pump directly on earth, gravel or debris since
this can cause excessive wear of the impeller and possible
jamming. Remove all debris from the bottom of the
sump pit before installation of the pump. A sump pit
cover is suggested for safety and to prevent foreign
objects from entering the pit.
Installation of Pump
1. Removal of old pump:
NOTE:
DISCONNECT PUMP FROM POWER
SOURCE BEFORE HANDLING.
Separate the discharge pipe at either the check valve or at
the union. If neither a check valve or union is part of the
existing discharge pipe, cut the pipe just above floor level
with a hacksaw and remove the pump. (A union or check
valve will need to be installed at this cut.)
2. *SEE NOTE BELOW. Set the new pump in place
making sure the float switch has adequate clearance and
will not hang-up on the pit wall.
3. A 1
1
⁄
4
" threaded discharge is provided on the pump for
connection to the discharge pipe. Do not reduce the
discharge size to below 1
1
⁄
4
" as this will affect pump flow
and performance. Schedule 40 PVC pipe is recom-
mended; however, flexible discharge hose kits may be
used for temporary installations.
4. Connect the pipe or the discharge hose to the discharge
of the pump. HAND TIGHTEN ONLY. Overtightening
may cause the pump housing to crack.
5. Install a union or other means of separating the dis-
charge pipe just above the floor to facilitate removal of
the pump if necessary. A check valve is recommended
just above or in place of the union to prevent the
backflow of water after each pump cycle.
If a check valve is used, a
1
⁄
8
" air bleed hole should be
drilled in the discharge pipe just above the pump’s
discharge outlet to prevent pump “airlock”. See
Figure A. A small spray of water out of this hole is
normal while pump is running.
6. Connect additional pipe as necessary to direct the
discharge to the desired location. Discharge should be
kept as short as possible with a minimum number of
turns. Check all connections for leaks.
WARNING

voltage
*NOTE: Pedestal pumps require assembly of the float, rod
and guide. Snap the plastic rod guide into its position with
its pin located in the center hole on the column of the
pump. Insert the threaded end of the float rod down
through the hole in the guide and attach the float ball to
the threaded end. Remove the upper rubber stop and insert
the rod through the hole in the switch arm. Replace the
upper rubber stop at least
1
⁄
2
" from the end of the rod.
