General Information

Attention:
This manual contains important
information for the safe use of this
product. DO NOT THROW AWAY OR
LOSE THIS MANUAL. Reasonable care
and safe methods should be practiced.
Check local codes and requirements
before installation.
WARNING: Before handling these
pumps and controls, always disconnect
the power first. Do not smoke or
use sparkable electrical devices or
flames in a septic (gaseous) or possible
septic sump.
Pump Cautions and
Warnings
DANGER: Risk of Electrical Shock
or Electrocution. May result in serious
injury or death or fire hazard. Installer
must disconnect all electrical sources
prior to installation, handling or
servicing. Only qualified personnel may
install this system. NFPA 70: National
Electric Code
(NEC) or local codes
®
must be followed. System must be
properly grounded according to NEC. Do
not lift pump by power cord.
DANGER: Biohazard Risk. Once
wastewater source has been connected to
system, biohazard risk exists. Installer(s)
and/or service personnel must use proper
personal protective equipment and
follow handling procedures per OSHA
29 CFR 1910.1030 when handling
equipment after wastewater source has
been connected to system.
DANGER: Risk of Asphyxiation.
Installer(s) and/or service personnel must
use proper personal protective equipment
and follow OSHA 29 CFR 1910.146
or OSHA 29 CFR 1926. Pump may be
installed in a location classified as a
confined space.
DANGER: Risk of Fire or Explosion.
Do not smoke or use open flames in or
around this system. HGRS200 systems
are not intended for use in hazardous
locations per NFPA 70: National Electric
Code. Do not pump flammable liquids.
DANGER: Cutting Risk. Risk of
serious cutting or amputation exists.
Disconnect all power sources prior to
servicing pump or grinding mechanism.
Pump may start without warning.
2
Grinding mechanism is extremely sharp.
Use caution when handling grinder
mechanism.
DO NOT modify the cord strain relief.
When wiring to a system control,
connect the pump ground lead to the
system ground.
DO NOT run the pump dry. Dry running
can overheat the pump (causing burns
to anyone handling it) and will void the
warranty.
The pump normally runs hot. To avoid
burns, allow it to cool for 30 minutes
after shutdown before handling it.
Submersible grinder pumps are not
approved for use in swimming pools,
recreational water installations,
decorative fountains or any installation
where human contact with the pumped
fluid is common. This specialized pump
is designed to incorporate a grinding
mechanism to remove wastewater
particulate and pump the resulting
slurry from a residential structure to a
collection system.
Examine all lifting devices, rope or
chain for damage before and after each
lift.
DO NOT exceed manufacturers
recommendation for maximum
performance, as this could cause the
motor to overheat.
Secure the pump in its operating position
so it cannot tip over, fall or slide.
DO NOT pump without safety devices
in place.
Basin must be vented in accordance with
the local plumbing codes.
CALIFORNIA PROPOSITION 65
WARNING:
This product and
related accessories contain chemicals
known to the State of California to
cause cancer, birth defects or other
reproductive harm.

Pump Installation

Installing Pump in Sump:
Before installing pump in sump, lay
it on its side and rotate impeller. The
impeller should turn freely. Do not
connect the power until after this test.
Clean all trash and sticks from sump and
connect pump to piping. A check valve
must be installed on each pump.
Location:
If pumps are installed in an existing
basin or concrete sump, the piping
can either be connected permanently
or rails and brackets can be furnished
for mounting to walls of basin. In
either case, be sure that the pumps are
submerged in a vertical position. The
complete factory-built packaged system
is recommended.
Making Electrical Connections:
All wires should be checked for shorts to
ground with an ohmmeter or Megger ®
after the connections are made.

Pump Operation

To reduce the risk of electrical shock,
install only on a GFCI protected circuit.
See pump nameplate for electrical
ratings.
To start the pump, perform the following
steps in order:
1. When grinder pump is single
phase, no rotation check
is necessary. Correct rotation is
counter-clockwise.
2. Run water into sump until motor is
covered.
3. Open gate valve in discharge line.
4. Turn pump on. If pump runs and
sump liquid does not pump down,
stop pump and close discharge
gate valve. Lift pump until sealing
flange is open to vent off trapped
air. Lower pump, open discharge
valve, and start the pump again.
CAUTION: Positive displacement
pump is designed to operate at
minimum 5 GPM capacity. Running
pump at shut-off condition or with
gate valve closed can result in damage
to the pumping stator boot and rotor.
5. Level control should be set so
that pump turns off when level is
about 2 inches above inlet of pump
suction and turns on when level is
about 2 inches above motor.
6. If problems occur, check power
source.
Make sure a separate supply line is
available.
Verify voltage supply.
