PUMP INSTALLATION
DESCRIPTION OF PUMP — This pump is intended to
grind and pump all normal sewage for home or commer-
cial use. It will also handle reasonable quantities of
disposable diapers, sanitary napkins, paper towels,
rubber material, wood, plastic, string, cigarette butts
and other material not normally found in sewage.
Pump is of heavy duty construction and submersible
type for long life when pumping ground sewage. Motor
is capacitor start, capacitor run for single phase.
Capacitors and start relay are mounted in electrical
control box.
Pump has two oil-filled chambers: (1) the motor and
ball bearings and (2) the seal chamber - for long life and
best heat transfer.
The lower seal above the pump impeller acts as a
buffer for upper seal that holds oil in the motor chamber.
If lower seal leaks for any reason, water enters the seal
chamber. If motor has the seal leak detector, the
electrode will contact the water and close the circuit to
the red seal light in the control panel indicting motor
must be serviced before upper seal fails.
A heat sensor is attached to stator winding to sense
any abnormal heat. If motor temperature for any cause
rises above 221°F the pump is immediately stopped
and will not restart until motor cools to a safe tempera-
ture.
PUMP CORDS — Each pump has two cords. The
power cord contains 4 conductors and the control cord
has 5 conductors. The larger of the two cords is the
power cord and smaller cord is the control cord.
The power cord for single phase uses the color coding
for start and main windings and connects to control box
terminal strip black (common), white (run), and red
(start). The green wire is always ground and connects
to ground terminal in control box. For three phase the
same 4 conductor color coded cords are used, the
black, white and red can be connected to any of the
three phase terminals in the control box.
The smaller control cord uses black and white leads for
heat sensor and connects to terminal strip in control
box. The red and orange wires connect to seal failure
terminals in control box and the green or ground lead
connects to ground terminal in control box.
IMPORTANT — Ground wires must be connected in the
control box to grounding bar, which is connected to a
good outside ground. MOTOR IS NOT SAFE UNLESS
GROUNDED.
INSPECTING PUMP — Before making any piping or
electrical connections check pump for any shipping
damage and turn grinder impeller to be sure it is free.
DO NOT TURN IMPELLER WITH FINGERS AS
EDGES ARE SHARP, use socket wrench in the
impeller screw.
CAUTION: After pump is installed NEVER WORK ON
MOTOR OR GRINDER UNIT WITHOUT DISCONNECT-
ING MOTOR LEAD WIRES FROM CONTROL PANEL.
DO NOT RELY ON OPENING CIRCUIT BREAKER
ONLY.
INSTALLING PUMP IN BASIN — Complete installation
and piping instructions are included with the basin
package.
To check rotation turn Hand-Off-Auto switch to OFF
position and turn on circuit breaker. Quickly turn H-O-A
switch to HAND position, then OFF. Note grinder
impeller rotation. Impeller must rotate counterclock-
wise. If rotation is wrong, change any two line leads to
motor at control box terminal. Recheck for proper
rotation. CAUTION: KEEP HANDS COMPLETELY
AWAY FROM GRINDER IMPELLER WHEN MAKING
THIS CHECK.
Where pump is installed remote from control box in
outside installation a different method is used.
Set the pump in the basin and run in some water so
pump can operate. Turn H-O-A switch to hand position
and let pump pull water down in basin. When water
reaches the bottom of pump, rotation of the water can
be observed. Water should rotate in a clockwise
direction if pump rotation is correct. If not correct
rotation, interchange any two line leads to motor at
control panel.
When replacing a pump with a new unit, rotation must
be checked.
