It is recommended that the level control float 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
filling 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 excessive
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 condi-
tion should be determined and repaired immediately. Thermal
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 flashlight, 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), refill the housing.

Model: EP40 & EP45 Series
Receiving and Installation
• 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 refilling with oil. To locate
the leak, perform the following pressure tests.
After leak is repaired, dispose of old oil properly, and refill
with new oil.
Motor Housing Pressure Test:
If oil has been drained, fill to normal level before performing
pressure test. Remove pipe plug from motor housing.
Apply pipe sealant to pressure gauge assembly and
tighten 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, leaks will seep oil. If, after five minutes, the pres-
sure 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 refill with new cooling oil, see "Cooling Oil" chart. Fill
to just above motor (.9L) as an air space must remain in
the top of the motor housing to compensate for oil expan-
sion. 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.

create a hazard. Overfilling oil voids warranty.

Pressure builds up extremely fast, increase
pressure by "TAPPING" air nozzle. Too much
pressure will damage seal.
DO NOT exceed 10 P.S.I.
DO NOT overfill oil. Overfilling
