Receiving and Installation
Receiving Inspection
Upon receiving the pump, it should be inspected for
damageorshortages.Ifdamagehasoccurred,leaclaim
immediately with the company that delivered the pump.
If the manual is removed from the packaging, do not lose
or misplace.
Storage
Any product that is stored for a period longer than six (6)
months from the date of purchase should be bench
tested prior to installation. A bench test consists of,
checking the impeller to assure it is free turning and a run
test to assure the motor (and switch if provided) operate
properly. Do not pump out of liquid.
IMPORTANT! A clearance under the
pump for entrance of sewage solids
must be a minimum of 2 inches to a maximum of 3.5
inches.
Submergence
The pump should always be operated in the submerged
condition. The minimum sump liquid level should never
belessthanabovethepump’smotor(seeg.1),unless
verybriey.
Installation
The sump or basin shall be sealed and vented in accor-
dance with local plumbing codes. This pump is designed
to pump domestic wastewater, nonexplosive and non-
corrosive liquids and shall NOT be installed in locations
classiedashazardousinaccordancewiththe
National Electrical Code (NEC) ANSI/ NFPA 70 or Cana-
dian Electric Code
(CEC). The pump
should never be
installed in a
trench, ditch,
or hole with
a dirt bottom.
The legs will
sink into the
dirt and the
suction will
become
plugged.
Discharge Piping
Install discharge piping or hose assembly to the pump.
Discharge piping should be as short as possible and sized no
smaller than the pump discharge. Do not reduce the dis-
charge pipe size below that which is provided on the pump.
Both a check valve and a shut-off valve are recommended
foreachpump.Thecheckvalveisusedtopreventbackow
into the sump. The shut-off valve is used to manually stop
systemowduringpumpservicing.Besurethedischarge
pipe has a 1/8” diameter hole approx. 5” from end nearest
volute and oriented towards the pump body.
Control Panel
SinglephaseseriesefuentpumpsDONOTrequireacon-
trol panel, but do require a level control with a piggy back
plug,see“Piggy-backPlug,gure2”below.
WARNING
Motor: Each motor is provided with heat sensor thermo-
stats attached directly to the motor windings. The
thermostats open if the motor windings see excessive heat
and, in turn, open the motor contactor in the control panel
when used, breaking the power to the pump. When the
motor is stopped due to an overheated condition, it will
not start until the motor has cooled.
FIGURE 1
Minimum
Submergance
Pre-operation
CHECK VOLTAGE AND PHASE
Before operating pump, check to make sure that voltage
andphaseinformationstampedonthepump’sidentica-
tion plate matches the available power.
CHECK PUMP ROTATION
Beforeputtingpumpintoserviceforthersttime,the
motor rotation must be checked. Improper motor rota-
tion can result in poor pump performance and
can damage the motor and/or pump.
IDENTIFICATION PLATE
Notethenumbersonthepumpsidenticationplateand
record in this manual for future reference.
Electrical Connections
Turn circuit breaker off before
plugging or unplugging the
switch and/or pump.
AlwaysrelyuponaCertiedElectricianforinstallation.
Piggy-Back Plug Plug the
level control plug into a
115Vreceptacle,thenplug
the pump into the piggy-back
plug (See Figure 2). It is
recommended that this circuit
have a 15 AMP breaker. One
cycle of operation should be
observed, so that any potential
problems can be corrected. FIGURE 2

Efuent Pumps
Model: EPH30
Receiving and Installation
Itisrecommendedthatthelevelcontroloatshouldbe
set to insure that the liquid in the sump never drops
below the top of the motor housing. The level control
should have adequate clearance so it cannot hang up in
it’s swing and that the pump is completely submerged
when the level control is in the “Off ” mode. Minimum
tether length is 3.50”.
By adjusting the cord tether the control level can be
changed. DO NOT USE THE POWER CABLE TO LIFT
PUMP.
Pump-Down Test - Be sure pump has been plugged in,
lowered into the basin or sump, check the system by
llingwithliquidandallowingthepumptooperate 
through its pumping cycle. The time needed to
empty the system, or pump-down time along with the
volume of water, should be recorded.
Thermal Protection
The normally closed (N/C) over temperature sensor is
embedded in the motor windings and will detect exces-
sive heat in the event an overload condition occurs.
The thermal sensor will trip when the windings become
too hot and will automatically reset when the pump
motor cools to a safe temperature.
In the event of an over temperature, the source of this con-
dition should be determined and repaired immediately. Ther-
mal protection shall not be used as a motor overload device.
Maintenance
Minimal maintenance is required. Perform the following
checks when pump is removed from operation or when
pump performance deteriorates:
a). Inspect motor chambers for oil level and
contamination.
b). Inspect impeller and body for excessive build-up or
clogging.
c). Inspect motor and bearings.
d). Inspect seal for wear or leakage.
Servicing
Cooling Oil - Anytime the pump is removed from
operation, the cooling oil in the motor housing should be
checked visually for oil level and contamination. To check
oil, set unit upright. Remove pipe plug from housing.
Withaashlight,visuallyinspecttheoilinthehousingto
make sure it is clean and clear, light amber in color and
free from suspended particles. Milky white oil indicates
the presence of water. Oil level should be just above the
motor when pump is in vertical position.
Oil Testing
• Drain oil into a clean, dry container by placing pump on
it’s side. Remove pipe plug, from housing.
• Check oil for contamination using an oil tester with a
range to 30 Kilovolts breakdown.
• If oil is found to be clean and uncontaminated
 (measuringabove15KV.breakdown),rellthehousing.
• If oil is found to be dirty or contaminated (or measures
• If oil is found to be dirty or contaminated (or measures
 below15KV.breakdown),thepumpmustbecarefully
inspected for leaks at the shaft seal, cable assembly,
 o-ringandpipeplug,beforerellingwithoil.Tolocate
the leak, perform the following pressure tests.
After leak is repaired, dispose of old oil properly, and
rellwithnewoil.
Pressure builds up extremely fast, increase
pressure by “TAPPING” air nozzle. Too much
pressure will damage seal.
DO NOT exceed 10 P.S.I.
Motor Housing Pressure Test:
Ifoilhasbeendrained,lltonormallevelbeforeperform-
ing pressure test. Remove pipe plug from motor housing.
Apply pipe sealant to pressure gauge assembly and tight-
en into hole. Pressurize motor housing to 10 P.S.I. Use
soap solution around the sealed areas above the oil level
and inspect joints for “air bubbles”. For sealed areas
belowoillevel,leekswillseepoil.If,afterveminutes,
the pressure is still holding constant, and no “bubbles” /
oil seepage is observed, slowly bleed the pressure and
remove the gauge assembly. Replace oil. Leak must be
located and repaired if pressure does not hold.
Oil Replacement Motor Housing
Remove pipe plug from motor housing.
Drain all oil (if not already done so) from motor housing
and dispose of properly per Local Code. Set pump
uprightandrellwithnewcoolingoil,see“CoolingOil”
chart. Fill to just above motor (0.34L) as an air space
must remain in the top of the motor housing to compen-
sate for oil expansion. Apply pipe thread compound to
threads of pipe plug then assemble to motor housing.
Check that o-ring is in place and does not need to be
replaced. Reassemble cord cap to motor housing.
DO NOT overll oil. Overlling of housing
with oil can create excessive and dangerous
hydraulic pressure which can destroy the
pump and create a hazard. Overlling
oil voids warranty.
