Receiving Inspection
Upon receiving the pump, it should be inspected for
damage or shortages. If damage has occurred, file a
claim immediately with the company that delivered the
pump. If the manual is removed from the packaging, do
not lose or misplace.
Storage
Any product that is stored for a period longer than six
(6) months from the date of purchase should be bench
tested prior to installation. A bench test consists of,
checking the impeller to assure it is free turning and a
run test to assure the motor (and switch if provided)
operate properly. Do not pump out of liquid.
IMPORTANT!
A clearance under the pump for
entrance of sewage solids must be a minimum of 3
inches to a maximum of 4.5 inches.
Submergence
The pump should always be operated in the submerged
condition. The minimum sump liquid level should never
be less than above the pump's volute (see fig. 1)
Installation
The sump or basin shall be sealed and vented in accor-
dance with local plumbing codes. This pump is designed
to pump domestic wastewater, nonexplosive and non-
corrosive liquids and shall NOT be installed in locations
classified as hazardous in accordance with the
National Electrical Code (NEC) ANSI/ NFPA 70 or Cana-
dian 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.

Discharge Piping
Install discharge piping or hose assembly to the pump.
Discharge piping should be as short as possible and sized
no smaller than the pump discharge. Do not reduce the dis-
charge pipe size below that which is provided on the pump.
Grinder Pumps
Model: AGP-HC200 Series
Receiving and Installation
Discharge Piping continued
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. Be sure the discharge
pipe has a 1/8" diameter hole approx. 5" from end nearest
volute and oriented towards the pump body.
Control Panel
Single phase series grinders with internal start components
DO NOT require a control panel. Single phase pumps with
the "E" designation have external start components and
do require a control panel. All three phase models require a
control panel. See Wiring Connections, page 11".
Motor
Single phase motors are provided with heat sensor
thermostats attached directly to the motor windings. The
thermostats open if the motor windings see excessive
heat and, in turn, open the motor contactor in the control
panel when used, breaking the power to the pump. When
the motor is stopped due to an overheated condition,
it will not start until the motor has cooled. Three phase
motors must be used with an appropriate controller with
integral overload protection.
Motor Seal Failure Warning
The seal chamber is oil filled and provided with moisture
sensing probes to detect water leakage through the
lower shaft seal. The probes can also detect moisture
present in the upper motor housing.
On single phase models, the presence of water energizes
a red seal leak warning light at the control panel. This is a
warning light only, and
does not stop the motor. It indicates a leak has occurred
and the pump must be repaired. Normally, this indicates
the outboard seal has leaked. Allowing the unit to
operate too long after the warning could cause upper
seal leakage along with motor failure.
The resistance across the moisture sensing (seal failure)

probes should be checked after a seal leak warning light

has lit. This can be done by disconnecting the black and
white control wires from the control panel, and measuring

the resistance with an ohmmeter between the wires.
The reading should be 100,000 ohms or greater. If the

the pump may have a lower seal failure and require
service.

Motor power cord, control cord and cord cap
Assembly
Each motor power cord has 4 conductors: white, black,
red and green.
For three phase motors the red, black and white con-
ductors connect to the three line leads, and the green is
connected to a good ground. Interchanging any two line
leads will reverse the rotation of the motor
(see Figure 7, page 11)
