Installation

There are several methods of installing 
grinder pumps. See contract plans and/
or specifi cation: A slide rail in a package 
system or concrete wet well is the most 
common, which allows the pump(s) 
to be installed or removed without 
requiring personnel to enter the wet 
well.

The sump or  basin shall be sealed 
and vented in accordance with local 
plumbing codes. 

This pump is designed 

to pump grinder or wastewater, 
nonexplosive and noncorrosive liquids 
and shall NOT be installed in locations 
classifi ed as hazardous in accordance 
with the National Electrical Code (NEC) 
ANSI/NFPA 70 or Canadian Electric 
Code (CEC).

 The pump should never be 

installed in a trench, ditch, or hole with 
a dirt bottom. The legs will sink into 
the dirt and the suction will become 
plugged.
The installation should be at a suffi

  cient 

depth to ensure that all plumbing 
is below the frost line. If this is not 
feasible, remove the check valve and 
size the basin to accommodate the 
additional backfl ow volume.

Discharge Piping

Discharge piping should be as short 
as possible and sized no smaller than 
the pump discharge.  

Do not reduce 

the discharge pipe size below that 
which is provided on the pump.

  Both 

a check valve and a shut-off  valve are 
recommended for each pump.  The 
check valve is used to prevent backflow 
into the sump.  The shut-off  valve is 
used to manually stop system flow 
during pump servicing.

Liquid Level Controls

The level control(s) should be mounted 
on the discharge piping, a cable rack 
or fl oat pole.  The level control should 
have adequate clearance so it cannot 
hang up in it’s swing and that the pump 
is completely submerged when the 
level control is in the “Off ” mode.  By 
adjusting the cord tether the control 
level can be changed.  One cycle of 
operation should be observed, so that any 
potential problems can be corrected.

It is recommended that the level control 
fl oat should be set to insure that the liquid 
in the sump never drops below the top of 
the motor housing or a minimum level of 
10 inches above the basin fl oor.

Electrical Connections

Power cable - 

The power cable mounted 

to the pump must not be modified in any 
way except for shortening to a specific 
application. Any splice between the pump 
and the control panel must be made in 
accordance with the electric codes. It 
is recommended that a junction box, if 
used, be mounted outside the sump or be 
of at a minimum Nema 4 construction if 
located within the wet well. 

DO NOT USE 

THE POWER CABLE TO LIFT PUMP. 

Always rely upon a Certifi ed Electrician 
for installation.

Thermal Protection:

The normally closed (N/C) over 
temperature sensor is embedded in the 
motor windings and will detect excessive 
heat in the event an overload condition 
occurs. The thermal sensor will trip when 
the windings become too hot and will 
automatically reset when the pump 
motor cools to a safe temperature. 

It is recommended that the thermal 
sensor be connected in series to an alarm 
device to alert that an overtemperature 
condition and/or motor starter coil to 
stop pump.

In the event of an overtemperature, 
the source of this condition should be 
determined and repaired immediately. 
Thermal protection shall not be used as a 
motor overload device. A separate motor 
overload device must be provided in 
accordance with NEC code.

 WARNING! - DO NOT LET
 THE PUMP CYCLE OR RUN IF
 AN OVERLOAD CONDITION 
 OCCURS !

If current through the temperature sensor 
exceeds the values listed, an intermediate 
control circuit relay must be used to 
reduce the current or the sensor will not 
work properly.
