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. MGPD200 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. 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.

INSPECTING PUMP

Before making any piping or electrical connections, 
check the pump for shipping damage or cracks. 
Using a flat screwdriver placed in the slot on the 
shaft end, turn shaft and impellers to be sure they 
are free. 

DO NOT TURN IMPELLER WITH FINGERS AS 

EDGES ARE SHARP.

CAUTION! NEVER WORK ON THE UNIT WITHOUT 

DISCONNECTING THE ELECTRICAL POWER CORD.

PUMP OPERATIONS

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.

  7.  Check resistance of windings. If not within guidelines, return 

pump to authorized factory service center.

As the motors are oil filled, no lubrication or other maintenance 
is required. Pump should be checked every quarter for corrosion 
and wear.

POWER SUPPLY

The D1C20-21 Series grinder pump should be connected only to 
a 230 volt, single phase, 60 Hz power source. The pump will draw 
approximately 9.1 amperes at minimum flow and 15.0 full load 
amperes. Locked rotor current is 57 amperes. The pump must be 
connected to a grounded power socket. 

DO NOT

 cut off the ground 

pin from the power cord plug.

POWER CORD

A 20 foot power cord is attached to the grinder pump via three 
insulated quick-disconnect terminals. To replace a cord simply 
unscrew (turn counterclockwise) cord nut from top of motor 
housing. Once cord nut is completely loosened from housing, 
gently pull cord upward away from housing. While cord is being
