Installation
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.
