CONDITION COMMON CAuSES
A. Pump will not start or run. Check fuse, low voltage, over load open, open or incorrect wiring,
open switch, impeller or seal bound mechanically, defective capaci-
tor or relay when used, motor or wiring shorted. Float assembly held
down. Switch defective, dam aged, or out of adjustment.
B. Motor overheats and trips overload or blows fuse. Incorrect voltage, negative head (discharge open lower than
normal) impeller or seal bound mechanically, defective capacitor or
relay, motor shorted.
C. Pump starts and stops too often. Float tight on rod, check valve stuck or none installed in long dis-
tance line, over load open, level switch(s) defective, sump pit too
small.
D. Pump will not shut off. Debris under fl oat assembly, float or fl oat rod bound by pit sides or
other, switch defective, damaged or out of adjustment.
E. Pump operates but delivers little or no water. Check strainer housing, discharge pipe, or if check valve is used
vent hole must be clear. Discharge head exceeds pump capacity.
Low or incorrect voltage. Incorrect motor rotation. Capacitor defec-
tive. Incoming water containing air or causing air to enter pumping
chamber.
F. Drop in head and/or capacity after a period of use. Increased pipe friction, clogged line or check valve. Abrasive mate-
rial and adverse chemicals could possibly deteriorate impeller and
pump housing. Check line. Remove base and inspect.
If the above checklist does not uncover the problem, consult the factory - Do not attempt to
service or otherwise disassemble pump.
SERVICE CHECKLIST
ELECTRICAL PRECAUTIONS- Before servicing a pump, always shut off the main power breaker and then unplug the pump
- making sure you are wearing insulated protective sole shoes and not standing in water. Under flooded conditions, contact
your local electric company or a qualified licensed electrician for disconnecting electrical service prior to pump removal.
1. DO read thoroughly all installation material provided
with the pump.
2. DO inspect pump for any visible damage caused
by shipping. Contact dealer if pump appears to be
damaged.
3. DO clean all debris from the basin. Be sure that the
pump will have a hard, flat surface beneath it. DO
NOT install on sand, gravel or dirt.
4. DO be sure that the basin is large enough to allow
proper clearance for the level control switch to operate
properly.
5. DO Always Disconnect Pump From Power Source
Before Handling.
DO always connect to a separately protected and
properly grounded circuit.
DO NOT ever cut, splice, or damage power cord (Only
splice in a watertight junction box).
DO NOT carry or lift pump by its power cord.
DO NOT use an extension cord with a sewage pump.
6. DO install a check valve in the discharge line.
DO NOT use a discharge pipe smaller than the pump
discharge.
7. DO NOT use a sewage pump as a trench or
excavation pump, or for pumping gasoline, or other
hazardous liquids.
8. DO test pump immediately after installation to be sure
that the system is working properly.
9. DO cover basin with an adequate cover and seals.
10. DO review all applicable local and national codes and
verify that the installation conforms to each of them.
11. DO consult manufacturer for clarifications or
questions.
12. DO consider a Two Pump System with an alarm where
an installation may become overloaded or primary
pump failure would result in property damages.
13. DO inspect and test system for proper operations at
least every 3 months.
