The following instructions
dene the recommended
procedure for installing the
Model WH/WR47 grinder pump
station.
This is a sewage handling
pump and must be vented in
accordance with local plumbing
codes. This pump is not to be
installed in locations classied
as hazardous in accordance
with National Electric Code,
ANSI / NFPA 70. All piping and
electrical systems must be in
compliance with applicable
local and state codes.
1. REMOVE PACKING
MATERIAL: The User
Instructions must be given to
the owner. Hardware supplied
with the unit, if any, will be used
at installation.
2. TANK INSTALLATION:
The tank is typically supplied
with a standard grommet for
connecting the 4” DWV (4.50”
outside dia.) incoming sewer
drain. Other inlet types and
sizes are optional. Caution:
4” DR-35 pipe has a smaller
diameter and won’t create
a watertight joint with the
standard 4” SCH 40 inlet
grommet. Conrm that you
have the correct inlet before
continuing. Do not drop, roll,
or lay tank on its side. This
will damage the unit and void
the warranty.
Excavate a hole to a depth so
that the station cover extends
1” to 3” above the nished
grade line. The nished
grade must slope away from
the station cover to prevent
surface water from entering
the station. The diameter of the
hole shall be large enough to
allow for the concrete ballast
anchor. The size, shape and
shoring requirements of the
excavation will be based on 240 VOLT WIRING – SIMPLEX
Figure 2b
120 VOLT WIRING – SIMPLEX

the soil conditions and must
be in accordance with the site
engineer’s recommendation
and safety requirements. Care
must be taken during lifting and
placement to prevent impacting
or otherwise damaging the tank
(see Lifting Instructions). Only
a non-marring sling, rated for
the load being lifted, should
be used in contact with the
tank surfaces. A pre-ballasted
tank must not be lifted with a
sling (see Lifting Instructions).
Lifting chains or cables should
not be placed in direct contact
with the tank surfaces. Fill the
excavation bottom with a 6”
deep bed of gravel, naturally
rounded aggregate, clean and
free owing, with particles not
less than 1/8” or more than 3/4”
in size.
A concrete ballast anchor is
required to prevent otation of
the tank when groundwater is
present. The concrete anchor
is not optional. The MINIMUM
concrete anchor requirements
for the WH/WR 47 station are
shown in Chart 1 of the Ballast
Calculation section.
Pour approximately 1” to 2”
of concrete onto the gravel
bed and place the tank into the
excavation. Ensure the tank
is properly positioned in the
excavation to support inlet pipe
(Section 3) and discharge pipe
(Section 5) connections before
pouring the concrete ballast.
The unit should be leveled
and lled with water, about 24”
deep, to prevent shifting while
the remaining ballast is being
poured. The concrete should
be vibrated, as necessary,
to eliminate voids. If it is
necessary to pour the concrete
above the inlet level (Section
3), the inlet must be sleeved
with an 8” tube before pouring.

Concrete ballast should be
cast in-place around the tank
in the excavation (Figure 3).
Alternatively, pre-cast ballast
around the base of the tank,
may be used. Ensure that 1”
to 2” of concrete is placed
beneath the tank base if pre-
cast ballast is used. If the
concrete is pre-cast, lifting
hooks must be anchored in the
ballast to support subsequent
handling of the tank (see Lifting
Instructions). The lifting hooks
used must be adequate to
support the combined weight of
the tank and concrete ballast
and shall be sized and installed
in accordance with the site
engineer’s recommendation.
Place the ballasted tank on
the gravel bedding in the
excavated hole using the
lifting hooks. Do not lift by
any of the tank surfaces if
pre-cast ballast is utilized.
3. INLET LOCATIONS:
A 4” DWV (standard) inlet
grommet was provided with
the station for sealing the
inlet pipe at the tank wall. If
the inlet grommet penetration
was not factory installed, the
location of the tank inlet must
be determined to support nal
positioning of the tank prior to
ballast installation (see Section
2). The inlet pipe location
corresponds with the actual
or projected point where the
building sewer line intersects
the tank wall. The grade of
the inlet pipe and required
burial depth (per national
and local code requirements)
must be accounted for when
determining the inlet location.
The supply cable path
should be considered when
selecting the inlet location (see
Section 8). A 5” diameter eld
penetration of the tank wall is
required to support installation
of the (standard) inlet grommet.
This penetration must not
remove or interfere with any
of the structural ribbing on the
polyethylene tank. The inlet
grommet may be installed in
any of the allowable locations
shown in Figure 7. The inlet
penetration must be centered
in the location selected to
prevent interference with
the tank ribbing. Typical inlet
installation will be on one of
the four, 10.5” diameter raised
pads on the tank body. The
pads have been marked with
a series of locating lines to
support centering of the 5”
(standard) drilled penetration.
Any inlet installed in the
depressed panels between the
horizontal and vertical ribbing
must be centered within the
panel to provide adequate
clearance for the 6” diameter
ange on the standard 4” inlet
grommet (Figure 7). Once the
location of the inlet penetration
is selected, mark the inlet
center location on the tank
and position the tank. Using
a 5” diameter hole saw for
a standard 4” grommet, drill
through the tank wall at the
marked location. Remove any
chips or burrs from the drilled
hole. Install the provided inlet
grommet into the drilled hole.
The grommet is self-sealing
and does not require the use of

Power at the station must not drop below 10% of nameplate
voltage. Maximum Recommended Length:
120 Volt 60’ (min. voltage at pump — 108V)
240 Volt 150’ (min. voltage at pump — 216V)
Consult factory for longer lengths
Figure 4
TYPICAL SUPPLY CABLE CONFIGURATION
additional sealant or adhesive.
4. INLET PIPE
INSTALLATION: Mark the
inlet pipe 3.5” from the end to
be inserted. Inlet pipe leading
edge should be beveled with
a grinder and lubricated with
a soap solution. Lubricate
the inlet grommet with soap
solution as well. Insert the pipe
into the grommet up to the 3.5”
mark. Inspect to ensure the
grommet has remained intact
and in place (Figure 7).
5. DISCHARGE: The use
of 1.25” PVC pressure pipe
SCH 40 and polyethylene
pipe SDR 11 or SIDR 7 are
recommended. If polyethylene
is chosen, use compression-
type ttings to provide a
smooth inner passage.
E/One requires that an
E/One Uni-Lateral assembly
(E/One part number
NB0184PXX or NC0193GXX)
or E/One Redundant Check
Valve (E/One part number
PC0051GXX) be installed in
the pipe lateral outside the
home between the pump
discharge and the street main
on all installations. Never use
a ball-type valve as a check
valve. E/One recommends
the valve be installed as close
to the public right-of-way as
possible. Check local codes for
applicable requirements.
CAUTION: Redundant check
valves on station laterals
and anti-siphon/check valve
assemblies on grinder pump
cores should not be used as
system isolation valves during
line tests.
There is a slide face valve
and a quick disconnect pre-
installed in the tank for grinder
pump connection. There is
a stainless steel 1.25” NPT
female discharge connection
on the outside of the tank
to support discharge piping
connection.
6. BACKFILL
REQUIREMENTS: Proper
backll is essential to the
long term reliability of any
underground structure.
Several methods of backll are
available to produce favorable
results with different native soil
conditions.
The recommended method
of backlling is to surround
the unit to grade using Class
I or Class II backll material
as dened in ASTM 2321.
Class 1A and Class 1B are
recommended where frost
heave is a concern; Class
1B is a better choice when
the native soil is sand or if a
high, uctuating water table
is expected. Class I, angular
crushed stone, offers an added
benet in that it needs minimal
compaction. Class II, naturally
rounded stone, may require
more compactive effort, or
tamping, to achieve the proper
density.
If the native soil condition
consists of clean compactible
soil, with less than 12% nes,
free of ice, rocks, roots, and
organic material, it may be
an acceptable backll. Such
soil must be compacted in
lifts not to exceed one foot to
reach a nal Proctor Density
between 85% and 90%. Non-
compactible clays and silts are
not suitable backll for this
or any underground structure
such as inlet or discharge
lines. If you are unsure of
the consistency of the native
soil, it is recommended that a
geotechnical evaluation of the
material be obtained before
specifying backll.
Another option is the use of
a owable ll (i.e., low slump
concrete). This is particularly
attractive when installing
grinder pump stations in
augured holes where tight
clearances make it difcult to
assure proper backlling and
compaction with dry materials.
Flowable lls should not be
dropped with more than 4
(BY OTHERS)

GRINDER PUMP STAND
feet between the discharge
nozzle and the bottom of the
hole because this can cause
separation of the constituent
materials.
7. VENTING: The unit must
be properly vented to assure
correct operation of the pump.
The units are supplied with a
2” vent opening in the cover
assembly. Failure to properly
vent the tank will result in faulty
operation and will void the
warranty.
If the water level outside
of the station is expected to
rise above the surrounding
grade (ooding), a cover vent
system cannot be used. If
ood conditions are expected,
an underground (lateral) vent
system and solid cover must be
used. Consult the factory if
ood conditions are possible
where the station will be
installed.
8. ELECTRICAL
CONNECTION: (Supply panel
to E/One alarm panel)
Before proceeding, verify that
the service voltage is the same
as the motor voltage shown
on the name plate. An alarm
device is to be installed in a
conspicuous location where it
can be readily seen. An alarm
device is required on every
installation. There shall be no
exceptions.
Wiring of supply panel and
alarm panel shall be per
Figures 2a–2d, alarm panel
wiring diagrams and local
codes. A dedicated 30 amp
breaker is required before
all simplex alarm panels. A
dedicated 30 amp breaker is
required before a 240V duplex
alarm panel, and a dedicated
40 amp breaker is required
before a 120V duplex alarm
panel.
9. ELECTRICAL
CONNECTION: (Pump to
Panel) (Fig. 4) The grinder
pump station is provided with a
cable for connection between
the station and the alarm panel
(supply cable) for each grinder
pump. The supply cable, a six
conductor tray cable, meets
NEC requirements for direct
burial as long as a minimum of
24” burial depth is maintained.
Those portions of the cable
which have less than 24” of
cover must be contained in
suitable conduit. This includes
the vertical portion dropping
to a 24” depth at the station
and the length rising out of the
ground at the control panel
(conduit by others). NOTE:
Wiring must be installed per
national and local codes.
Conduit must enter panel from
bottom and be sealed per NEC
section 300.5 & 300.7.
9a. Installing E/One supply
cable:
1) Open the lid of the station
and locate the cable and the
feed-thru connector on the
wall of the shroud or on the
inside wall of the tank (Model
WH/WR47 x 77”). Loosen the
nut on the connector and pull
the supply cable out through
the connector until it hits the
crimped-on stop feature on
the cable, approximately 36”
from the EQD. **IMPORTANT:
All but 36” of the cable must
be pulled out of the station,
and the Equalizer and EQD
should be secured in the hook
provided to ensure that the
pump functions properly. Do
not leave the excess cable in
the station.
2) Retighten the nut. This
connection must be tight or
ground water will enter the
station.
3) Feed the wire through the
length of conduit (contractor
provided), which will protect it
until it is below the 24” burial
depth.
4) On models WH/WR47
x 92” and taller, position the
conduit vertically below the
cable connector along side
of the station reaching down
into the burial depth. Attach
the small protective shroud
provided with the station to
protect the exposed cable
where it enters the station.
Four self-tapping screws are

9
provided.
5) Run the cable
underground, in a trench or
tunnel, to the location of the
alarm panel. Leave a 6- to 12-
inch loop of cable at each end
to allow for shifting and settling.
Connections made at the panel
are shown in the panel wiring
diagram (Figures 2a–2d).
10. GRINDER PUMP STAND
ASSEMBLY: Temporarily
rest the grinder pump on its
side. Using a block of wood
or similar object, prop up
the lower pump end to allow
installation of the pump stand.
Align the two legs of each
pump stand half with two of
the holes in the pump lower
end (Figure 5). Push the stand
legs into the pump lower end.
Using a mallet, ensure that
the stand legs bottom into the
mounting holes. Repeat for the
other stand half. Turn the pump
upright on the installed stand.
11. DEBRIS REMOVAL:
Prior to start-up test procedure,
the incoming sewer line
must be ushed to force all
miscellaneous debris into
the tank. Next, all liquid and
debris must be removed. Once
the tank is clean, install the
pump(s) and proceed with the
test.
12. INSTALL THE PUMP:
Lower the pump into the
tank. Position the pump so
the pump’s discharge is on
the opposite side of the pump
relative to the discharge in
the tank. Position the pump
in the center of the tank.
Rotate to coil the discharge
hose and slide the adapter on
the discharge hose into the
receiver in the tank wall until
it seats. Push the white slider
down to open the discharge
valve. Refer to Figures 8–11
for slideface connection and
operation.
Hang power cable, breather
tubing with Equalizer, and
lifting rope to prevent them
from laying in sewage. The
Equalizer should be hung as
high as possible in the tank.
13. TEST PROCEDURE
The following steps should
be taken to verify proper
installation and operation:
a) Make sure that the
discharge slide face valve(s)
is fully open. This valve(s)
must not be closed when the
pump is operating. In some
installations, there may be a
valve, or valves, at the street
main that must also be open.
(Ignore all Trouble
indications, LEDs and/or
messages until the panel
is reset at the end of this
procedure.)
For model WH/WR 471:
b) Fill the tank with
approximately 200 gallons of
water (approximately up to the
top of the grinder pump).
c) Turn on the pump power
and alarm circuit breakers in
the alarm panel. The grinder
pump and alarm should turn on
immediately.
d) Monitor the pump and
alarm to ensure they are
operating correctly. The alarm
will shut off at a water level
of approximately 18” from the
bottom. The grinder pump
will shut off at a water level
of approximately 14” from the
bottom. Proceed to Step i.
For model WH/WR 472:
b) Fill the tank with
approximately 200 gallons of
water (approximately up to the
top of the grinder pump).
c) Turn on the Pump #1
power breaker and the alarm
circuit breakers in the alarm
panel. Grinder Pump #1 and
the alarm should turn on
immediately.
d) Monitor the pump and
alarm to ensure they are
operating correctly. The alarm
will shut off at a water level
of approximately 18” from the
bottom. The grinder pump
will shut off at a water level
of approximately 14” from the
bottom.
e) Turn off the Pump #1 and
alarm circuit breakers.
f) Rell the tank with
approximately 200 gallons of
water (approximately up to the
top of the grinder pump).
g) Turn on the Pump #2
power breaker and the alarm
circuit breakers in the alarm
panel. Grinder Pump #2 and
the alarm should turn on
immediately.
h) Monitor the pump and
alarm to ensure they are
operating correctly. The alarm
will shut off at a water level
of approximately 18” from the
bottom. The grinder pump
will shut off at a water level
of approximately 14” from the
bottom.
i) Clear/Reset the alarm
panel:
Sentry and T260 panels:
Reset is not required.
Protect Panel: Turn pump
and alarm breakers off and
back on simultaneously.
Protect Plus Panels: Perform
a “cold start” from the Initialize
System menu. Any user setting
that were previously chosen
will not be reset.
j) If any Trouble or alarm
conditions are indicated after
the panel is reset, contact your
local service provider.

Field Joint Assembly Instructions
Parts included in Field Joint Kit:
Identify all parts before proceeding
with installation.
(16) 3/8-16 X 1-1/2 long screws
(16) 3/8-16 Elastic Stop Nuts
(32) Flat Washers
(1) Length Sealant (Sika) Tape
(1) Hole Punch
1) Carefully clean and dry both
accessway anges with solvent.
IMPORTANT: Sealing surfaces
must be dry to ensure the
sealant adheres correctly.
2) Starting at one hole of tank
ange, apply two layers of Sika
Tape around the inside half of the
ange. Align the outside edge of
the tape with the bolt circle. Move
to the adjacent hole and apply
one layer of Sika Tape around
the outside of the ange. Align
inside of tape with the bolt circle.
Remove the backing paper as you
lay the adhesive on the ange.
Do not stretch Sika tape during
application, it may result in a
leak. The tape should overlap at
the end by approximately 1/2 inch,
as shown in Figure 6a. If a section
of Sika Tape is misapplied, the
bad section may be cut out and
replaced. Cut away the poorly laid
portion cleanly with a knife and be
sure to over lap the tape at each
end about 1/2 inch.
3) Using the tool provided,
punch a hole through the tape at
each of the 16 existing bolt holes
in the ange. Be careful to keep
the exposed sealant clean and
dry.
4) Insert three of the sixteen 3/8-
16 x 1-1/2” long bolts, with a at
washer, into the ange attached to
the upper part of the accessway.
These will act as guides while
aligning the bolt pattern of the two
anges.
5) Support the upper accessway
section a few inches over the tank
with the green stripes on each
lined up. Once aligned, lower the
upper section onto the mating
ange using the three bolts to
guide it to the proper position. See
Figure 6b.
6) Insert the remaining 13 bolts
with at washers into the anges.
Place a at washer and elastic
stop nut on the end of each bolt,
turning the nut on just enough to
hold the washer in place.
7) Tighten up the bolts until
the sealant begins to squeeze
out from between the anges.
To ensure a consistent, sturdy
seal tighten them in the following
sequence: 1, 9; 5, 13; 3, 11; 7, 15;
2, 10; 4, 12; 6, 14; 8, 16. Always
be sure to tighten one bolt and
then the bolt at the position 180°
from it, see Figure 6a for position
numbers.
8) Using the same sequence as
in step 7 tighten each bolt to 60
in-lbs. Visually inspect the joint,
each bolt and each nut should
have a at washer between it and
the ange, and a uniform amount
of sealant should be protruding
from the seam along the entire
perimeter.
In the event that there are
any voids in the sealant, the
joint may leak. Take corrective
actions if necessary and be
sure that the joint is leak free
before continuing.
IT IS EXTREMELY IMPORTANT THAT THE JOINT IS SEALED PROPERLY BEFORE
BACKFILLING. EXCAVATING A UNIT FOR REPAIR IS VERY EXPENSIVE AND CAN BE EASILY
AVOIDED BY USING PROPER CAUTION DURING THE FOLLOWING PROCEDURE.

Lifting Instructions
FAILURE TO FOLLOW THESE INSTRUCTIONS COMPLETELY WILL VOID WARRANTY.
1. Transporting unit to
installation site: Always lift a
unit from the bottom for the
purpose of transportation.
The station should be
received attached to a pallet
for this purpose. Never roll a
station or move it on its side.
2. No Ballast (to be poured in
place): If the concrete anchor is
to be poured while the station
is in place lift the unit using two
nylon straps wrapped under
the tank ange to make a sling,
as shown below. Keep station
oriented vertically to avoid any
damage.
3. Precast Ballast: Never
lift a station that has a ballast
attached by any means except
the rebar. The weight of the
concrete will damage the
station if you attempt to lift it
from any part of the station.

E/One Grinder Pump Station Ballast Calculations
Sample Calculation — Station Height of 92”
Volume of Station = 73.1 ft3
Station Weight = 350 lbs
Station Height = 7.3 ft
A. Buoyant Force
1. The buoyant force acting on the submerged WH/WR47 is equal to the weight of the displaced
water for the section of the tank that is submerged.
Fbuoyant = (density of water)(volume of station)
= (62.4 lbs/cu ft)(73.1 cu ft)
= 4560 lbs
2. The net buoyant force acting on the station (Fnet-buoyant) is equal to the buoyant force (Fbuoyant)
minus the weight of the station tank.
Fnet-buoyant = 4560 lbs – 350 lbs
= 4210 lbs
B. Ballast Force
1. Determine the volume of concrete and soil
Section I: Used To Determine The Volume Of Concrete
(Note: 4.0 ft = assumed inside diameter of concrete ballast ring around tank’s bottom ange)
Volume = (Height)(Area)
= (.83 ft)(π)((5.6 ft)2– (4.0 ft)2) / 4
= (.83 ft)(12.06 ft2)
= 10.1 ft3
Section II: Used To Determine The Volume Of Saturated Soil
(Note: 4.3 ft = assumed inside diameter of soil column around tank’s maximum diameter)
Volume = (Height)(Area)
= (7.3 ft – .83 ft)(π)((5.6 ft)2– (4.26 ft)2) / 4
= (6.46 ft)(10.1 ft2)
= 65.2 ft3
2. Determine the combined ballast
Ballast (total) = Ballast (concrete) + Ballast (saturated soil)
= (Vconcrete)(density concrete in water) + (Vsoil)(density saturated soil)
= (10.1 ft3)(87.52 lbs/ft3) + (65.2 ft3)(70 lbs/ft3)
= 884 lbs + 4564 lbs
= 5450 lbs
C. Subtract the buoyant force from the ballast force to determine the nal condition
Final Condition = Ballast Force – Net Buoyant Force
= 5450 lbs – 4210 lbs
= 1240 lbs (excess ballast)

Adjusting the Height of a Grinder Pump Station
TO INCREASE STATION HEIGHT 6 INCHES
1. Increasing station height can be done without cutting the station. Use the E/One Extender cover shroud
kit (ND0082G01) and follow the instructions that are included with the kit.
TO INCREASE STATION HEIGHT MORE THAN 6 INCHES or TO REDUCE THE STATION HEIGHT:
REMOVE EXISTING COVER ASSEMBLY
(Fig. 12)
If your existing station has a welded-on
cover shroud, you will need the appropriate
replacement cover kit.
1. Turn off all power to the grinder pump
station.
2. Remove the tank lid and the electrical
shroud.
3. Unplug the electrical quick disconnect
(EQD) and remove the EQD from the supply
cable. Note: DO NOT CUT CABLE. Loosen
liquid-tight cable connector and pull the
supply cable out through the connector on
the side of tank.
4. Remove the soil around the tank, exposing three of the tank corrugations below grade. Use caution not to
damage buried cable.
5. Remove existing cover shroud.
5a. Welded-on shroud (standard) — Using a hand saw, cut the tank in the valley between the two
corrugations at grade, discard
existing welded on shroud and
attached corrugations (shroud
is not to be reused). Caution:
Be careful not to cut the pump
breather cable.
5b. Clamped-on shroud
— Remove band clamp and
cover shroud.
REDUCING STATION
HEIGHT (Fig. 13)
6. Using a hand saw, cut the tank in the valley
between the two corrugations at grade.
INSTALL REPLACEMENT COVER ASSEMBLY
(Fig. 14)
7. Clean top corrugation on accessway extension
and mating surface of replacement shroud with
acetone.
8. Liberally apply the silicone sealer provided to the
under side of the replacement shroud where it will
come in contact with the accessway extension.
9. Place SS band clamp around top corrugation
and the replacement shroud. Tap with a mallet
around clamp to help seat the clamp. Torque stud
assembly on band clamp to a maximum 125 inlb.
10. Reinstall the supply cable, EQD, tank lid and

User Instructions for the Environment One Grinder Pump
General Information
Your home is served by a low pressure sewer system; the key element is an Environment One grinder pump.
The tank collects all solid materials and wastewater from the house. The solid materials are then ground to a
small size suitable for pumping as a slurry with the wastewater. The grinder pump generates sufcient pressure
to pump this slurry from your home to the wastewater treatment receiving line and/or disposal plant.
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: 1) this
device may not cause harmful interference; and 2) this device must accept any interference received, including
interference that may cause undesired operation. Any changes or modications not expressly approved by the
party responsible for compliance could void the user’s authority to operate this equipment.
Care and Use of your Grinder Pump
The Environment One grinder pump is capable of accepting and pumping a wide range of materials, and an
extensive grind test is required in order to obtain NSF approval. However, regulatory agencies advise that the
following items should not be introduced into any sewer, either directly or through a kitchen waste disposal unit:
Glass Seafood shells Diapers, socks, rags or cloth Syringes
Cotton swabs Personal/cleaning wipes & sponges Disposable toothbrushes Latex/vinyl items
Metal Plastic objects (toys, utensils, etc.) Kitty litter Dental oss
Aquarium gravel Sanitary napkins or tampons Cigarette butts
Caution: Kitchen garbage disposals do not keep grease/oil out of the plumbing system
In addition, you must never introduce into any sewer:
Explosives Strong chemicals Lubricating oil and/or grease
Flammable material Gasoline
Items introduced into the sewer system from your home can potentially impact the water environment. Proper
disposal of household wastes such as window cleaners, unused/expired pharmaceuticals, paint thinners, fats,
fruit labels, etc. is important. For more information, visit http://www.wef.org.
Periods of Disuse
If your home or building is left unoccupied for longer than a couple of weeks, perform the following procedure:
Purge the System. Run clean water into the unit until the pump activates. Immediately turn off the water and
allow the grinder pump to run until it shuts off automatically.
Duplex Units. Special attention must be taken to ensure that both pumps turn on when clean water is added to
the tank.
Caution: Do not disconnect power to the unit
Power Failure
Your grinder pump cannot dispose of wastewater without electrical power. If electrical power service is
interrupted, keep water usage to a minimum.
Pump Failure Alarm
Your Environment One grinder pump has been manufactured to produce an alarm signal (120 volt) in the
event of a high water level in the basin. The installer must see that the alarm signal provided is connected
to an audible and/or visual alarm in such a manner as to
provide adequate warning to the user that service is required.
During the interim prior to the arrival of an authorized service
technician, water usage must be limited to the reserve
capacity of the tank.
For service, please call your local distributor:
