WARNING! 

THE  PUMP  MUST  BE  WIRED  BY  A  QUALIFIED 
ELECTRICIAN, USING AN APPROVED STARTER 
BOX AND SWITCHING DEVICE.  
 
On  3  phase  pumps  only,  “Motor  Protection” 
must  be  provided  by  the  installer.  All  3  phase 
pumps must  be  installed with  magnetic  starters 
having  3  leg  overload  protection  in  accordance 
with  the  NEC  (National  Electric  Code).  For 
duplex  installations,  both  pump  motors  must 
have separate overload protection. 
 
Pumps  with  seal  leak  detectors  must  be 
connected to the proper control circuitry. 
 
DANGER! 
HAZARDOUS MOVING PARTS. To reduce risk of 
injury, disconnect power before servicing. Never 
put fingers near grinder impeller or in pump inlet 
when  pump  cord  is  connected  or  pump  is 
operating. 
 
For use with maximum 140 degrees F liquid.  
 
DANGER! 
In  the  initial  installation,  before  sewage  is 
admitted  to  the  basin,  there  is  no  danger  on 
entering the basin. AFTER SEWAGE HAS BEEN 
IN  THE  BASIN,  THERE  IS  DANGER.  Sewage 
water  produces  methane  and  hydrogen  sulfide 
gasses,  both  of  which  are  highly  poisonous.  A 
breathing  device  may  be  required.  Never  enter 
the  basin  unless  cover  is  open  and  outside 
blower  is  used  to  force  fresh  air  into  the  basin. 
Also  the  worker  in  the  basin  must  wear  a 
harness  attached  to  the  surface  so  he  can  be 
pulled out in case of asphyxiation. 
NEVER WORK ALONE! 
 
WARNING! 
Do not exceed working load limit of lifting chain, 
cable  or  rope.  Do  not  use  lifting  chain,  cable  or 
rope where failure could result in loss of life. 
 
Examine  all  lifting  devices,  chain,  cable  or  rope 
for damage before and after each lift. Do not use 
any  lifting  devices  that  are  not  rated  for  and 
designed  to  lift  the  weights  involved  with  these 
pumps. DO NOT LIFT PUMP BY POWER CORD. 
 
Do not install or remove pump with person(s) in 
the basin. 
 
This  pump  is  designed  to  handle  materials 
which  could  cause  illness  or  disease  through 
direct  exposure.  Wear  and  use  protective 
clothing when working on the pump or piping. 

WARNING ! 
Any wiring to be done on pumps should be 
done by a qualified electrician. 
 
NEVER operate a pump with a power cord that 
has frayed or brittle insulation. 
 
NEVER let cords or plugs lay in water. 
 
NEVER handle connected power cords with 
wet hands. 
 
NEVER be in contact with the liquid being 
pumped while pump cord is connected to 
electrical supply.
