PREINSTALLATION CHECK LIST
* MODEL 104 IS NOT
IAPMO APPROVED.
Notice to Installer: Instructions must remain with installation.
1. Inspect your unit. Occasionally, prod ucts are dam aged during ship ment. If the unit is damaged, contact your dealer before using. DO NOT remove the test
plugs from the pump.
2. Care ful ly read the literature provided to familiarize yourself with specifi c details regarding installation and use. These ma te ri als should be re tained for future
reference.
SEE BELOW FOR LIST OF WARNINGS
1. To reduce the risk of elec tri cal shock, a prop er ly ground ed receptacle of
grounding type must be in stalled and pro tect ed by a ground fault circuit
in ter rupt er (GFCI) and in ac cor dance with National Elec tri cal Code and lo cal
codes.
(SEE WARNING BELOW)
2. Make certain that the receptacle is with in the reach of the pump’s pow er
supply cord. DO NOT USE AN EX TEN SION CORD. Extension cords that
are too long or too light do not deliver suf fi cient voltage to the pump motor.
But more im por tant, they could present a safety hazard if the in su la tion were
to become damaged or the connection end were to fall into the sump.
3. Testing for Ground. As a safety mea sure, each elec tri cal outlet should be
checked for ground using an Un der writ ers Lab o ra to ry Listed cir cuit analyzer
which will in di cate if the pow er, neutral and ground wires are correctly con nect ed to your outlet. If they are not, call a qualifi ed electrician.
4. For Added Safety. Pump must be con nect ed to a 3-prong ground ed outlet
in ter rupt er de vice (ground fault circuit in ter rupt er).
5. FOR YOUR PROTECTION, ALWAYS DIS CON NECT PUMP FROM ITS
POWER SOURCE BE FORE HAN DLING. Single phase pumps are sup plied
with a 3-prong ground ed plug to help protect you against the possibility of
electrical shock. DO NOT, UNDER ANY CIR CUM STANC ES, RE MOVE THE
GROUND PIN. To re duce the risk of electrical shock, a properly grounded
re cep ta cle of ground ing type must be installed and pro tect ed by a ground
fault circuit interrupter (GFCI) in ac cor dance with national electrical code and
local codes.
6. Installation and checking of electrical cir cuits and hard ware should only be
performed by a qualifi ed licensed electrician.
7. Risk of electric shock - These pumps have not been in ves ti gat ed for use in
swimming pool areas.
8. According to the state of California (Prop 65), this product contains chemicals
known to the state of California to cause cancer and birth defects or other
reproductive harm.
1. Check to be sure your power source is adequate for handling the voltage
requirements of the motor, as in di cat ed on the pump or basin plate.
2. Make sure the pump electrical supply cir cuit is equipped with fuses or circuit
breakers of proper ca pac i ty. A sep a rate branch circuit is rec om mend ed, sized
according to the National Elec tri cal Code for the current shown on the pump
name plate.
3. All plumbing (discharge and vent lines) must be in stalled to meet local codes.
Unit must be vented. DO NOT USE AN AUTOMATIC PLUMBING VENT
DEVICE SIM I LAR TO A "PRO-VENT". Some states require this product to
be installed by a licensed plumber.
4. Repair and service should be performed by Zoeller Pump Com pa ny Au tho rized
Service Station only.
5. CHECK VALVE MUST BE USED TO REDUCE UN NEC ES SARY CYCLING
OF PUMP. Check valve must be purchased sep a rate ly on model 104 only.
6. Dewatering pumps are not designed or intended for han dling raw sewage.
7. Maximum operating temperature for 105-131 Drain Pumps must not exceed
130°F (54°C). 104 Drain Pumps are not to exceed 110°F (43°C).
8. For health reasons, do not unplug, turn off, or disable pump and use pump
tank system as a way to fi ll up a sink or laundry tray, etc.
9. Unit is designed for above ground installation only.
NOTE: Pumps with the “UL” mark and pumps with the “US” mark are tested to
UL Standard UL778. CSA Certifi ed pumps are certifi ed to CSA Standard
C22.2 No. 108.

Service Checklist
ELECTRICAL PRECAUTIONS- Before servicing a pump, always shut off the main power breaker and then unplug the pump - making sure you are not standing in water and wearing insulated protective sole shoes. Under fl ooded conditions, contact your local electric company or a
qualifi ed licensed electrician for disconnecting electrical service prior to pump removal.
Submersible pumps can become pressurized under normal operating conditions — allow 2½ hours after disconnecting before attempting
service.
CONDITION

B. Motor overheats and trips over load
or blows fuse.
C. Pump starts and stops too often.
D. Pump will not shut off.
E. Pump operates but delivers little
or no wa ter.
F. Drop in head and/or capacity after
a period of use.
COMMON CAUSES
Check fuse, low voltage, over load open, open or incorrect wiring, open switch, impeller or seal bound me chan i cal ly,
defective capacitor or relay when used, motor or wiring shorted. Float assembly held down. Switch defective,
dam aged, or out of adjustment.
Incorrect voltage, negative head (discharge open lower than normal) impeller or seal bound mechanically, defective capacitor or relay, motor shorted.
Float too tight on rod, check valve stuck, or none installed in long distance line, over load open, switch
defective.
Debris under fl oat as sem bly, fl oat or fl oat rod bound by basin sides or other, switch defective, damaged or out of adjustment.
Check strainer housing, discharge pipe, or if check valve is used, the vent hole must be clear. Dis charge head
ex ceeds pump capacity. Low or incorrect voltage. Incorrect motor rotation. Ca pac i tor defective. Incoming water
con tain ing air or causing air to enter pump ing chamber.
Increased pipe friction, clogged line or check valve. Abrasive material and ad verse chem i cals could possibly
deteriorate impeller and pump housing. Check line. Remove base and inspect.
G. If tank or fi ttings leak.
If the above checklist does not uncover the problem, consult the factory - Do not attempt to service or otherwise disassemble pump. Service must
be by Zoeller Authorized Service Stations.
