GENERAL MAINTENANCE
Repair and sevice should be performed by an authorized
Zoeller
®
representative.
SAFETY PROCEDURES
For your protection, always disconnect pump
and panel from its power source before handling.
Never enter the basin until it has been properly
vented and tested. Any person entering a basin should be wearing
a harness with safety rope extending to the surface so they can
be pulled out in case of asphyxiation. Sewage water gives off methane and
hydrogen sulde gases, both of which can be highly poisonous.
Installation and servicing of the pump's electrical circuits and hardware should
be performed by a qualied electrician.
Pump is never to be lifted by power cord.
Unit must be cleaned and disinfected, inside
the pumping chamber and all exterior surfaces, prior to servicing.
GENERAL SYSTEM INSPECTION
Before the system is placed into operation, it should be inspected by a
qualied technician.
Wiring and grounding must be in accordance
with all governing codes and ordinances.
LUBRICATION PROCEDURES
No lubrication is required.
If pumps are to be stored for more than six months, refer to short-term storage
procedure in the Operation section.
PREVENTIVE MAINTENANCE
Preventive maintenance is recommended to ensure a long service life from the
product. Provided is a suggested maintenance schedule.
Every six months:
• Check for proper and unobstructed oat operation.
• Listen for proper check valve operation.
Every 5 years or 10,000 hours of operation:
• Remove pump, inspect and service using a Zoeller
®
rebuild kit.
• Flush and clean basin.
DOUBLE SEAL PUMPS
Double seal pumps offer extra protection. During every inspection of the unit,
check the control panel's seal failure light for a warning. Whenever the seal leak
light is activated, it's indicating that moisture is present and the pump should
be removed and serviced in order to avoid damage to the motor.
SERVICE CHECKLIST
Always disconnect pump from its power source before handling. Wear insulated protective sole shoes and do not stand in
water. Under ooded conditions, contact your local electric company or a qualied licensed electrician to disconnect electrical service prior to
pump removal.
Pump contains oil which becomes pressurized and hot when operating. Allow 2-1/2 hours after disconnecting before attempting service.

Condition Common Causes
A. Pump will not start or run.
Blown panel or circuit breaker fuse, low voltage, thermal overload open, impeller clogged, oat
switch held down or defective, incorrect wiring in control panel, water in cap assembly.
B. Motor overheats and trips on overload.
Incorrect voltage, impeller blocked, negative head (discharge lower than intake of pump). Pump
runs continuously at low water level. Low oil level in motor shell.
C. Pump will not shut off. Air lock, debris under oat assembly, incoming sewage exceeds capacity of pump.
D. Pump operates but delivers little or no water.
Intake clogged with grease or sludge, pump air locked (clear vent hole), low or incorrect voltage,
clogged discharge line, operating near shut-off head.
E. Pump starts and stops too often.
Check valve stuck open. Sump pit too small to handle incoming sewage. Level control out of adjust-
ment. Thermal overload tripping.
F. Large red ashing light comes on at control box. High water in pit. Check pump for clogging, or overload trip. See “A” and “D” above.
G. Grease and solids accumulate in pit around pump.
Break up solids and run pump with water running into the pit. Allow level to lower to the pump intake.
Continue until solids are cleared from the pit. Do not drain kitchen grease down the sink.
