Pre-Operation
1. Check Voltage and Phase compare to the voltage and
phase information stamped on the pump name plate.
2. Plug cord into an 208 or 230 volt receptacle with
ground fault circuit interrupter (GFCI) (single phase).
3. Check Pump Rotation - Improper motor rotation can
result in poor pump performance and can damage
the motor and/or pump. Check rotation by momen-
tarily applying power and observe the "kickback".
Kickback should always be in a counter-clockwise
direction as viewed from motor end or opposite to
impeller rotation. Incorrect rotation for Single-Phase
pumps is unlikely. If the rotation is incorrect contact
factory.
4. Name Plate - Record the information from the pump
name plate for future reference.
5. Pump-Down Test - Lower pump into basin or sump and
plug into power receptacle, 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.
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.
e). Inspect cutters for wear
Servicing
NOTE: Item numbers in ( ) refer to part numbers shown
on page 14 and 15.
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 (15) from housing
(19). With a flashlight, visually inspect the oil in the hous-
ing (19) 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 (30), from housing (28).

• 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.
• If oil is found to be dirty or contaminated (or measures

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.

Cord Cap Pressure Test:
See Figure 3. Remove pipe plug (30) from cord cap (45).
Apply pipe sealant to pressure gauge assembly and
tighten into hole. Pressurize upper motor housing to 10
P.S.I. Use soap solution around the sealed area above
the oil level and inspect for "air bubbles" around the
joint between the cord cap (45) and motor housing (28).
Also check around gland nut and power cable. If, after
five minutes, the pressure is still holding constant, and
no "bubbles" / oil seepage is observed, slowly bleed the
pressure and remove the gauge assembly. If no leak has
been found, continue to the Motor Housing Test.
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, fill to normal level before per-
forming pressure test (See Figure 3). Remove pipe plug
(30) from motor housing (28).
