USAGE: 
The  2  HP  grinder  pumps  are  for  pumping 
domestic sewage. One pump can handle the 
sewage from a maximum of 2 homes.  
 
These  pumps  are  not  to  be  used  for 
pumping  commercial  or  industrial  sewage 
from factories, schools, motels, apartments, 
etc.. 
 
This pump is intended to grind and pump all 
normal  sewage  for  home  use.  It  will  handle 
reasonable quantities of disposable diapers, 
sanitary  napkins,  paper  towels,  rubber 
material,  wood,  cigarette  butts,  string, 
plastic  and  other  material  not  normally 
found in sewage. 
 
CAUTION! 
Pump is not to be disassembled in the field 
except  at  certified  service  stations  or at  the 
factory.  Warranty  is  void  if  pump  is  taken 
apart  for  any  reason  other  than  to  replace 
grinder  impeller  and  grinder  ring,  which  is 
covered in these instructions. 
 
PACKAGING 
Each  pump  is  packaged  with  30  feet  of 
power  cord  in  a  carton  that  is  marked  with 
the  Model  Number.  Longer  cords  are 
available 

– consult factory. 

 
INSPECTING PUMP 
Before  making  any  piping  or  electrical 
connections,  check  pump  for  any  shipping 
damage.  Turn  grinder  impeller  to  be  sure  it 
is  free.  DO  NOT  TURN  IMPELLER  WITH 
FINGERS AS EDGES ARE SHARP. Use allen 
wrench  in  the  impeller  screw  to  turn  the 
impeller. 
 
CAUTION! 
No  persons  should  be  in  the  basin  when 
pump  is  lowered  into  position!  DO  NOT  lift 
pump in a manner where failure could result 
in loss of life. 
 
After  pump  is  installed  in  basin,  NEVER 
WORK  ON  MOTOR  OR  GRINDER  UNIT 
WITHOUT  DISCONNECTING  MOTOR  LEAD 
WIRES  FROM  CONTROL  PANEL.  DO  NOT 
RELY 

UPON 

OPENING 

THE 

CIRCUIT 

BREAKER ONLY! 

ELECTRICAL: 

MOTOR OVERLOAD PROTECTION 
Single phase motors are provided with an 
on-winding thermal overload switch. If 
motor overloads or overheats for any 
reason, the switch opens, stopping motor. 
As soon as the motor cools to normal 
temperature, the switch automatically 
closes and restarts motor. 
 
MOISTURE DETECTION 
All 2 HP, dual seal grinder pumps with 
external start kit or 3-phase, contain an 
electrode for detecting water within the unit. 
The electrode is housed within the 
secondary seal chamber, isolated from the 
motor chamber. If the electrode detects 
water within the oil-filled housing, it will 
close the circuit to the red alarm light in the 
control panel, indicating the pump must be 
serviced before the upper seal fails. 
 

MOTOR POWER CORDS  

Pump models with seal leak detector, single 
phase use a 10AWG-5C cord, three phase 
use a 14AWG-7C cord. Models without seal 
leak use a 10AWG-3C cord. The three power 
conductors are BLACK, WHITE and RED. 
The ORANGE conductor connects to the 
seal leak probe and GREEN conductor 
connects to the ground screw inside the 
cord cap.  
For single phase, 

BLACK

 is 

“Common”

 

WHITE

 is 

“Run

” 

RED

 is 

“Start

”. 

 
IMPORTANT! 
Ground wires must be connected in the 
control box to grounding bar, which is 
connected to a good suitable ground. 
MOTOR IS NOT SAFE UNLESS PROPERLY 
GROUNDED. 
 
IMPELLER ROTATION: When looking at the 
bottom of the pump and through the inlet of 
the volute, rotation of the impeller is 
COUNTER-CLOCKWISE.
