The following instructions
dene the recommended
procedure for installing the
Model WH101F grinder pump
station.
The Model WH101F is
a sewage-handling pump
station and must be vented in
accordance with local plumbing
codes. Do not install the unit
in locations classied as
hazardous in accordance with
the 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: Give the User
Instructions to the homeowner.
Hardware supplied with the
unit, if required, will be used
during installation.
2. Tank Installation: The
tank is supplied with a standard
4-inch PVC DWV (4.5 inches
inside dia.) inlet socket for
connecting the incoming sewer
drain. If a concrete ballast is
attached to the tank, lift only
by the lifting eyes embedded
in concrete. Do not drop, roll
or lay the tank on its side.
Doing so may damage the
unit and void the warranty.
Excavate a hole to a depth so
the removable cover extends
2 inches above the nished
grade line; the grade should
slope away from the unit. The
diameter of the hole must
be large enough to allow a
concrete anchor.
Place the unit on a 6-inch
bed of gravel, naturally
rounded aggregate, clean and
free-owing, with particle size
no less than 1/8 inch or more
than 3/4 inch in diameter. The
concrete anchor is required to
keep the unit from oating as
a result of high groundwater Figure 2a – 120V Simplex
levels. The amount of concrete
required varies for each unit
(see page 10 for the correct
ballast weight).
The unit should be leveled
and lled with water to the
bottom of the inlet; doing so
prevents the unit from shifting
when pouring the cement.
The cement must be manually
vibrated to eliminate any voids.
If pouring the cement to a level
higher than the inlet piping is
necessary, place an 8-inch
sleeve over the inlet prior to
pouring the cement.
3. Discharge: Using
1 ¼-inch PVC (SCH-40)
pressure pipe or polyethylene
water service tubing (SDR-9,
Type PE3206 or PE3306) with
a minimum pressure rating of
160 psi is recommended. If
polyethylene pipe is chosen,
use compression-type ttings
to provide a smooth inner
passage (insert ttings are
susceptible to clogging).
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

5
Figure 2b – 240V Simplex
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.
4. Vent: The station must
be vented to a height above
the expected maximum ood
level. Using 2 inch PVC pipe,
solvent weld pipe into the
PVC socket near the top of
the tank. Route pipe above
ood level, ensuring the pipe
always angles down towards
the station so no traps (low
spots) are created. Place a
gooseneck at the top of the
vent to prevent rainwater
and other foreign objects
from entering the vent. Install
factory-provided screen and
nut to bottom of gooseneck.
Failure to vent the station
properly will prevent the station
from venting and will void the
warranty.
5. Backll Requirements:
Proper backll is essential to
the long-term reliability of any
underground structure.
Several methods of backll
are available and each yields
favorable results when done
properly. Clean, compact,
native soil that is free from
rocks, roots or organic material
may be used if compacted in
lifts not to exceed one foot. It
must be compacted to a nal
Proctor density between 85
and 90 percent. Heavy, non-
compactable clays are not
acceptable backll for this or
any underground structure
such as inlet or discharge lines.
Class 1 or Class 2 backll
material as dened by ASTM
2321 may also be used.
Crushed stone and gravel
backll materials o󰀨er an
advantage since they typically
reach a compaction level of 90
to 95 percent standard density
with minimal compaction.
Another option is owable ll
(i.e., low slump concrete). This
is particularly attractive when
installing grinder pump stations
in augered holes where tight
clearances make it di󰀩cult to
assure proper backlling and
compaction with dry materials.
Flowable lls should not be
dropped more than four feet
from the discharge nozzle to
the bottom of the hole since
this can cause separation of
the constituent materials.
6. Electrical Connection
(supply panel to 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 by the
homeowner. An alarm device is
required on every installation.
There shall be no exceptions.
Wiring of supply panel and
alarm panel shall be per Figure
2a or 2b, alarm panel wiring
diagrams and local codes. A
dedicated 30 amp breaker is
required before all simplex
alarm panels.

6
7. Electrical Connection
(pump to panel): The cable
provided for connection
between the station and
alarm panel is a six-conductor
tray cable that meets NEC
requirements for direct burial
as long as a minimum of 24
inches of cover is maintained.
Those portions of cable that
have less than 24 inches of
cover must be contained within
suitable conduit. This includes
the vertical section that drops
to a 24-inch depth at the station
and the length exiting out of
the ground at the control panel.
Note: Wiring must be installed
in compliance with local codes
(which may vary from above).
The maximum distance
between the pump and panel
is 100 feet. NOTE: Wiring
must be installed per national
and local codes. Conduit must
Figure 3
enter panel from bottom and be
sealed per NEC section 300.5
& 300.7.
Failure to seal conduit may
cause premature pump failure
and void warranty.
Power source to the panel
must be 240 VAC (or 120
VAC for a 120V model). A
dedicated 30-amp breaker with
ground and separate neutral is
required.
8. Installing E/One supply
cable with EQD:
a. Open the lid of the
station, locate the cable and
the feed-thru connector on the
wall of the tank. 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 24” from
the EQD.
**IMPORTANT: All but 24”
of the cable must be pulled
out of the station, and the
portion of the cable between
the EQD and the molded in
cable breather should be
secured in the hook provided to
ensure that the pump functions
properly. Do not leave the
excess cable in the station.
b. Retighten the nut. This
connection must be tight or
ground water will enter the
station.
c. Feed the wire through the
length of conduit (contractor
provided) which will protect it
until it is below the 24” burial
depth.
d. Position the conduit
vertically below the cable
connector along side of the
station reaching down into the
burial depth.
Run the cable underground,
in a trench or tunnel, to the
location of the E/One 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 (Fig. 2a and 2b).

9. Debris Removal: Before
the start-up test procedure,
ush the incoming sewer line to
force all miscellaneous debris
into the tank. Next, remove
all liquid and debris. Once the
tank is clean, install the pump
and test.
10. 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. 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. Install the four retaining
rings (included with installation
instructions; Fig. 3).
11. Slide Face Discharge:
Refer to any documentation
that may have shipped with
your discharge. Attach the
discharge hose to the anti-
siphon check valve. Use
pipe sealer on threads to
ensure leak tightness (Fig.
4). Check the O-ring on the
slideface adapter for adequate
lubrication (Fig. 6). Attach
discharge installation tool on
male adapter (Figs. 4 and 5).
12. Pump Installation:
Lower the pump into the
tank. Position the pump so
the pump’s anti-siphon check
valve is on the opposite side
of the pump relative to the
discharge in the tank. Position
the pump in the center of the
Figure 6 Figure 7 Figure 8
Figure 9

tank. Refer to the Installation
Layout drawing in the front of
this manual.
Rotate discharge hose and
male adapter to create a loop
or coil. Slide male adapter into
slide face receiver until it seats.
Push down on slider valve
assembly to open (Fig. 9).
Hang power cable, breather
tubing with Equalizer, and
lifting rope to prevent them
from laying in sewage. Keep
between 18 inches and 24
inches of power supply cable in
tank. The Equalizer should be
hung as high as possible in the
tank. Refer to the “Installation
Layout” drawing in the front of
this manual.
13. Test Procedure: Make
certain that all discharge
shuto󰀨 valves are fully open
(curb stops, slider valve, etc.).
Turn o󰀨 power at main power
supply and panel. (Ignore all
Trouble indications, LEDs and/
or messages until the panel
is reset at the end of this
procedure.)
Use an ohmmeter set at
the 2 meg scale. Check
the continuity between the
following leads from the pump
(tests should be performed with
the pump and alarm breakers
inside the panel OFF):
•Green/yellow to red
•Green/yellow to black
•Green/yellow to brown
•Brown to yellow
All of these tests must read
an open circuit. A short at any
of these test points will cause
premature pump failure if not
corrected.
Turn on power at main power
supply only. Check voltage
from the main power supply.
The voltage must be 240 VAC
(or 120 VAC for a 120V model)
within 10 percent. Note the
voltage.
Turn on the alarm power
circuit breaker. Leave pump
breaker o󰀨.
Fill tank with water until
alarm turns on. This will be
about 30 inches from bottom
of tank. Turn o󰀨 water. Turn on
pump power circuit breaker.
Pump should immediately
turn on. Within one minute the
alarm will turn o󰀨. Within three
minutes the pump will turn o󰀨.
Take a current (amperage)
reading o󰀨 the black lead to the
pump. The reading should be
between 5 and 8 amps for 240
VAC service (10 to 16 amps for
120 VAC service).
Higher amperage readings
equal a higher discharge
pressure. If the amperage is
greater than 8 (16 for 120 VAC
service) check the discharge
line for a blockage. Note the
amperage.
Within the rst 1 to 3 minutes,
the alarm will turn o󰀨. Within
the following 1 to 2 minutes,
the pump will turn o󰀨 (in a 24-
inch diameter tank).
Clear/Reset the alarm panel:
• Sentry and T260 panels:
Reset is not required.
• Protect Panel: Turn pump
and alarm breakers o󰀨 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.
If any Trouble or alarm
conditions are indicated after
the panel is reset, contact your
local service provider.
Close and lock the alarm
panel.
Inspect the lid gasket and
install new gasket material as
required. Fasten lid to tank.
Call your local E/One
distributor if you experience
any problems. Please have
ready the unit serial number,
voltage, amperage read during
startup, type of application, and
a description of the problem.

Grinder Pump Station Ballast Calculations
Any buried vessel that is submerged, or partially submerged, in water will be acted on by an upward
buoyant force that attempts to return the vessel to a non-submerged state. The magnitude of this
buoyant force is equal to the volume of the vessel that is submerged multiplied by the density of
water. On most in-ground installations a ballast, or concrete anchor, of proper volume and weight is
required to resist the buoyant force.
The amount of ballast needed is equal to the weight it would take to counterbalance the buoyant
forces that are exerted on the station. The total ballast is a combination of the concrete poured to
create a ring around the bottom of the station and the soil above that ring which act as a weight.
The ballast force, the force holding the station down, must be greater than the buoyant force, the
force pushing the station up, in order to have an acceptable installation.
Calculate the Buoyant Force:
STATION VOLUME X THE WEIGHT OF WATER PER CUBIC FOOT (62.4 LBS/CU FT) =
BUOYANT FORCES
BUOYANT FORCES – STATION WEIGHT =
NET BUOYANT FORCE
Example: WH101-92,
28.53 cu ft X 62.4 lbs/cu ft = 1780.3 lbs
1780.3 lbs – 270 lbs = 1510.3 lbs
Calculate the Ballast Force:
VOLUME OF CONCRETE X WEIGHT OF CONCRETE WATER (87.6 LBS/CU FT) =
BALLAST FROM CONCRETE
VOLUME OF CONTRIBUTING SOIL X WEIGHT OF SATURATED SOIL (70 LBS/CU FT) =
BALLAST FROM SOIL
BALLAST FROM CONCRETE + BALLAST FROM SOIL = NET BALLAST FORCE
Example: WH101-92,
concrete: 2.7 cu ft X 87.6 lbs/cu ft = 236.5 lbs
soil: 20.4 cu ft X 70 lbs/cu ft = 1430.0 lbs
236.5 lbs + 1430.0 lbs = 1665.5 lbs
Net Ballast Force @ 1665.5 lbs > Net Buoyant Force @ 1510.3 lbs
Acceptable
Example, WH101-92:
Station Volume = 28.5 cu ft
Station Weight = 270 lbs
Contributing Soil Volume = 20.4 cu ft
Recommended Concrete Volume = 2.7 cu ft (O.D. = 36”)

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 su󰀩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 o󰀨 the water and
allow the grinder pump to run until it shuts o󰀨 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.
