EASY DO'S & DON'T'S FOR INSTALLING A SUMP PUMP
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 sump. 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 sump is large enough to allow proper clearance
for the level control switch(es) 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 sump pump.
6. DO install a check valve and a union in the discharge line.
DO NOT use a discharge pipe smaller than the pump discharge.
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.
Submersible pumps contain oils which becomes pressurized and hot under operating conditions. Allow 2-1/2 hours after
disconnecting before attempting service.
CONDITION
A. Pump will not start or run.
B. Motor overheats and trips overload
or blows fuse.
C. Pump starts and stops too often.
D. Pump will not shut off.
E. Pump operates but delivers little
or no water.
F.
Drop in head and/or capacity after
a period of use.
If the above checklist does not uncover the problem, consult the factory. Do not attempt to service or otherwise disassemble pump. Service
must be performed by Zoeller Authorized Service Stations. Go to www.zoellerpumps.com/servicestations to find the Authorized Service Station
in your area.
SERVICE CHECKLIST
COMMON CAUSES
Check fuse, low voltage, overload open, open or incorrect wiring, open switch, impeller or seal bound
mechanically, defective capacitor or relay when used, motor or wiring shorted. Float assembly held
down. Switch defective, damaged, or out of adjustment.
Incorrect voltage, negative head (discharge open lower than normal) impeller or seal bound mechani-
cally, defective capacitor or relay, motor shorted.
Float tight on rod, check valve stuck or none installed in long distance line, overload open, level switch(s)
defective, sump pit too small.
Debris under float assembly, float or float rod bound by pit sides or other, switch defective, damaged or
out of adjustment.
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 defective.
Incoming water containing air or causing air to enter pumping chamber.
Increased pipe friction, clogged line or check valve. Abrasive material and adverse chemicals could
possibly deteriorate impeller and pump housing. Check line. Remove base and inspect.

7. DO NOT use a sump pump as a trench or excavation pump, or for
pumping sewage, gasoline, or other hazardous liquids.

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 consider a D.C. Backup System where a sump or dewatering pump
is necessary for the prevention of property damages from flooding
due to A.C. power disruptions, mechanical or electrical problems or
system overloading.
14. DO inspect and test system for proper operations at least every three
months.
