RECEIVING & INSTALLATION
Installation
There are several methods of installing grinder pumps. See contract plans and/ or specification: 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 classified
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 sufficient 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 backflow 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 float 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 float
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 floor.

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 DO NOT USE THE POWER CABLE TO LIFT PUMP.
Always rely upon a Certified Electrician for installation.
CSA
Incoming Power Configurations-Incoming voltage must match the control panel voltage. Power cord: Certified/
UL recognized, Min NO.14/3, type SJOW or better.
Thermal Protection:
A motor thermal protector is embedded in the motor windings and will detect excessive heat in the event an overload
condition occurs. The thermal protector will trip when the windings become too hot and will automatically reset when
the pump motor cools to a safe temperature. In the event of an over temperature, the source of this condition should
be determined and repaired immediately.
WARNING! - DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION OCCURS!
