IMPORTANT!
Manufacturer is not responsible for losses, injury
or death resulting from failure to observe these
safety precautions, misuse or abuse of pumps or
equipment.
Control Panels:
All control panels used on these grinders are UL
listed and CSA certied. Control panels mounted
directly to the basin used outdoors are UL listed
and CSA certied waterproof.
Pumps:
Model D2C20-21 is UL and CSA approved.
Level Sensing Controls:
Intrinsically safe type oat controls are
recommended for all applications. An intrinsically
safe control panel relay will limit the current and
voltage to the level controls. A control panel can
be supplied with this type circuitry.
The oat level controls maintain the basin sewage
water level by controlling pump turn-on and turn-
o level.
1. The lower turn-o control should be set so that
the pump stops at approximately the top of the
pump.
2. The upper turn-on control should be set above
the lower turn-o control. The exact height
between the two controls is determined by the
number of pump starts desired and the depth
of the basin. A maximum of 10 starts per hour
should not be exceeded.
3. The override control is set at a specied height
above the upper turn-on control.
4. The alarm control is set about 6" to 12" above
the override control.
5. No control should be set above the inlet invert.
CAUTION — No persons should be in the basin
when pump is lowered into position! DO NOT lift
pump in a manner where any failure could result in
loss of life.
Air Venting:
Air tends to trap in the pump volute when water
raises in the sump or when the pump is lowered
into water after service. To vent o this air, a small
hole is drilled into the pump volute. Be sure this
vent hole is clean after any service work on pump.
USAGE — The D2C20 series 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 such as from
motels, schools, apartments, factories, etc.

PUMP OPERATIONS PUMP CUTAWAY
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 ange
is open to vent o 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-
o 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 o 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 lled, no
lubrication or other maintenance is
required. Pump should be checked
every quarter for corrosion and
wear.

PUMP MODELS — The D2C20-21 pumps are 230
volt, single phase, 3450 rpm. The D2C20-23 pumps
are 230 volt, three phase, 3450 rpm.
PACKAGING — Each pump is packaged with 10
feet of power cord in a carton that is marked with
Model Number and Engineering Number. Longer
cords are available, consult catalog.
INSTRUCTIONS — Instructions cover only the
pump unit. Separate instructions for the electrical
control panel and basin packaged system are
included with these items. Complete disassembly
instructions are furnished only to authorized service
stations.
CAUTION — PUMP IS NOT TO BE DISASSEMBLED
IN THE FIELD EXCEPT AT CERTIFIED SERVICE
STATIONS OR AT FACTORY. WARRANTY IS VOID
IF PUMP IS TAKEN APART FOR ANY REASON
EXCEPT
TO REPLACE GRINDER IMPELLER AND GRINDER
RING WHICH IS COVERED IN
THESE INSTRUCTIONS.
DESCRIPTION OF PUMP — Figure 1 shows
cutaway of pump with parts called out. This pump
is intended to grind and pump all normal sewage for
home use. It will also handle reasonable quantities
of disposable diapers, sanitary napkins, paper
towels, rubber material, glass, 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 the
electrical control box. All single phase motors must
have special electrical control box furnished by Delta
Manufacturing.
INSTALLING SINGLE PHASE MOTORS WITH
CONTROLS OTHER THAN MANUFACTURERS
VOIDS WARRANTY.
THREE PHASE MOTORS MUST HAVE PROPERLY
SIZED OVERLOADS IN CONTROL PANEL OR
WARRANTY IS VOID.
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
DISCONNECTING MOTOR LEAD WIRES FROM
CONTROL PANEL. DON’T RELY ON OPENING
CIRCUIT BREAKER ONLY.
Pump has two oil-lled 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 buer 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
indicating motor must be serviced before upper seal
fails.
MOTOR OVERLOAD PROTECTION — The motor is
provided with an on-winding 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 closes and restarts the
motor.
MOTOR POWER CORDS — Pump models with the
seal leak detector use a 5 conductor #14 gauge cord.
The three power conductors are BLACK, WHITE, RED,
the BROWN conductor connects to the seal leak probe
and GREEN conductor connects to the ground screw
inside the cord cap.
With 14/5 cords the BLACK and WHITE are main
winding leads and the RED is for start winding.
CORD SEAL — The lines from the motor chamber are
sealed with a rubber sealing grommet that prevents
oil from leaking into the cord cap compartment. If
necessary to replace power cord, the sealing grommet
must not be loosened. This wire seal is removed only
for complete motor repair that must be done at an
authorized motor repair shop.
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.
INSTALLING PUMP IN SUMP BASIN — Complete
installation and piping instructions are included with the
sump basin package.
SINGLE PHASE CONTROL BOX — Single phase
pumps must use the Delta control box. Warranty is
void if other than Delta single phase control box is
used.
THREE PHASE CONTROL BOX — Any suitable three
phase control equipment can be used for simplex
or duplex operation. These control boxes are also
available from Delta. If other than Delta box is used,
overload heaters must be selected in accordance with
full load amp ratings given in these instructions.

If any amp readings are higher than listed, it indicates
voltage may be higher or lower than normal, or that pump
grinder may be clogged with trash causing extra load on
motor.
CHECK LIST IF PUMP DOES NOT OPERATE PROPERLY
CHECKING FOR MOISTURE IN MOTOR — Disconnect line
leads from terminal strip. Use ohmmeter and set on highest
scale. Readings on the large power cord between any of
the conductors red, black, white to green or motor housing
should be more than 500,000 ohms. Motor probably will
run with a lower reading, but if pump is out of service and
reading is below 500,000 ohms, the motor housing and
stator should be removed and baked by an authorized
service station.
RESISTANCE OF WINDING —
Every motor winding has a
fixed resistance and winding must check close to the values
given in chart to operate properly. This winding resistance
also shows if motor is connected for voltage being used. Use
ohmmeter for this test and set on scale to read directly in
ohms.
CONDITION
Pump runs but does not
pump liquid from basin.
Red light comes on at control
box
PROBABLE CAUSE
1. Pump impeller may be air locked, this occasionally occurs on a new
installation. Start and stop pump several times to purge air.
2. Run additional water into basin so that pump will be submerged
deeper to clear air.
3. If air does not clear, it may be necessary to lift pumpout of sealing
elbow and start motor to allow pump to pump for a few seconds. If
discharge is piped in with union, slightly break union and start pump
to clear air. Air vent hole is provided in pump case, so some water
will ow from this hole when pump is operating. If vent hole gets
clogged, clean out.
4. If pump has been installed for some time and does not pump, it may
be clogged at grinder inlet.
5. Discharge gate valve may be closed.
6. Discharge check valve may be clogged or have a broken clapper.
7. Discharge head may be too high. Check elevation. Maximum pump
head at zero ow is 70 feet. See pump curve.
8. If above checks do not locate trouble, motor rotor may be loose on
shaft which allows motor to run but will not turn impeller or only at
low RPM.
1. This indicates some water has leaked past the lower seal and has
entered the seal chamber and made contact with the electrode
probe. Pump must be removed from basin within approximately two
(2) weeks for replacement of lower seal. This preventative repair will
save an expensive motor.
TROUBLE CHECK LIST
Troubles listed below are generally not caused by the pump. Other trouble can occur from faulty control box
operation. These will be listed with the control box instructions.

23833A595 8
1. Push in red reset button to reset overload. If overload trips again after
short run, pump has some damage and must be removed from basin for
checking.
2. Trouble may be from clogged grinder causing motor to overload or could
be from failed motor.
3. Trouble may be from faulty component in control box. Always check
control box before removing pump.
1. Indicates H-O-A switch be in the hand position.
2. Level control switch may have failed causing pump to continue to oper-
ate when water is below lower oat.
3. Grinder assembly may be partially clogged causing pump to operate at
very reduced capacity.
4. Check valve may be clogged causing low pump ow. Gate valve may
be in o position.
5. Pump may be air locked.
1. Reset breaker by pushing clear down on handle then back to on posi-
tion. If breaker trips again in few seconds it indicates excessive load
probably caused by a short in the motor or control box. Check out
instructions given with control box before pulling pump.
2. If this condition happens after an electrical storm, motor or control box
may be damaged by lightning.
3. Resistance reading of the motor with lead wires disconnected from the
control box can determine if trouble is in motor or control box.
1. Grinder assembly may be partially clogged with some foreign objects
causing noise and overload on the motor.
2. Grinder impeller may be rubbing on grinder ring due to bent shaft or mis-
alignment.
1. Pump “ON” switch may be set too high.
2. Run pump on hand operation for several minutes with small amount
of water running into basin to clean out solids and grease. This allows
pump to break suction and surge which will break up the solids.
3. Trash may have accumulated around lower weight causing pump to turn
o too soon. Clean trash from weight and suspension cable.
Overload trips and alarm buzzer
or ashing red light comes on
due to high water level in basin
Yellow run light stays on con-
tinuously
Circuit breaker trips
Pump is noisy and pump
rate is low
Grease and solids have accumu-
lated around pump and will not
pump out of basin
CONDITION PROBABLE CAUSE

23833A5959
This is the only disassembly operation allowed
in the eld. All other repair must be done at the
factory or at an authorized service center.
STANDARD
1. Allen head socket set
2. Standard socket wrench set
3. Set of open end wrenches.
4. Plastic hammer
5. Vise grip pliers
6. Large screwdriver with heavy handle
7. Wire brush
8. Three-cornered le
IMPORTANT— Pump should be thoroughly cleaned

CAUTION: DISCONNECT ALL POWER AND
CONTROL WIRES TO MOTOR AT CONTROL PANEL
BEFORE STARTING DISASSEMBLY OPERATIONS.
NEVER RELY ON OPENING CIRCUIT BREAKER
ONLY.
DISASSEMBLY OF SHREDDING RING AND
GRINDER IMPELLER
1. Remove three screws from grinder ring ange.
Grinder ring is pressed into ange for easy
removal. See Fig. 1
2. Thread two screws into tapped back-o holes in
ange and evenly tighten screws to back grinding
ring out of pump housing. See Fig. 2
3. Hold grinder impeller by prying against impeller
cutting bar and remove cap screw from end of
shaft. See Fig. 3
4. Use large screwdriver in slot in end of shaft and
bump on cutter vane with plastic hammer. Bump
in counterclockwise direction as thread is right
hand. It may take several bumps to loosen
impeller. See Fig. 4
5. If impeller comes o easily clean up and replace if
worn.

Fig. 3
REPLACING GRINDER IMPELLER AND GRINDER SHREDDING RING

23833A595 10
6. Be sure pump impeller has not loosened when
grinder impeller is removed. This can be checked
on reassembly of grinder impeller and shredding
ring. Tips of impeller cutter vanes should extend
about 1/8" below bottom of shredding ring. If
distance is more, it means the pump impeller has
loosened, and if it is less, it means the shredding
ring is not properly seated.
If the pump impeller has loosened, remove grinder
impeller and shredding ring as described above
and remove bolts from volute case and remove
case. Plastic hammer can be used to bump on
casing discharge to loosen. Place gasket in oil
to prevent drying out. DO NOT loosen the pump
impeller further - it is the seat for the lower seal
spring.
7. After case is removed wrap emery paper around
shaft and hold with vise grip pliers. Use cloth
on impeller and screw up against shoulder. Now
pump can be reassembled. See Fig. 5
8. Clean all threads with wire brush and le smooth
any threads that may be nicked.
9. Use Never-Seeze or other graphite compound on
threads before replacing grinder impeller.
10. Be sure cap screw in bottom of shaft is tight. Hold
impeller with screwdriver between cutter bar and
teeth of shredding ring while tightening cap screw.
11. Be sure impeller turns free by hand after
reassembly. Some drag will occur due to the
seals, but there should be no binding or tight spots
when turning the grinder impeller. See Fig. 6
12. If impeller rubs or drags on shredding ring, loosen
bolts in shredding ring plate and tap with plastic
hammer to loosen, retighten screws. Be sure to
pull screws down evenly, applying pressure on all
three screws. DO NOT TIGHTEN ONE SCREW
CLEAR DOWN BEFORE ADJUSTING OTHER
SCREWS.
13. ALWAYS use a rag on the impeller when turning
to prevent cutting hands on the sharp corners of
shredding ring.
