Once the above has been verifi ed proceed with the following checks:
• Pump power cables properly connected to panel.
• Float cables properly connected to panel.
• Conduit connections to panel are properly sealed.
• Thermal overload adjustments made in the panel.
• After installing the pump into the containment area, with adequate
submergence, open the discharge valve fully. Start the unit using
manual controls. If fl ow is appreciably less than rated performance,
pump may be air locked. To expel trapped air, jog the unit several
times, using the manual controls.
• Have a qualifi ed electrician take voltage and current measurements
on the black wire of single phase or all three power wires of three
phase with the pump running. Record these readings in the space
provided in the “Owner’s Information” section on page 1 of this
manual for future reference.
After the preoperational functional test has been completed, system
is ready for operation. Zoeller requires completing a Start-up Report
(ZM1074) whenever a system is started for the fi rst time or after a
system has had a signifi cant change take place (i.e. pump replacement,
overhaul, etc..). A copy of the Start-up Report should remain with the
system for future reference.
Operation
(continued)
ADJUSTMENT PROCEDURE
Pumps: No adjustments are required other than assuring correct
rotation.
Panels: The thermal overloads in the panel must be set to the F.L.A. rat-
ing on the pump nameplate (or refer to pump data sheet).
Floats: Refer to the system drawing for desired location of each fl oat
function.
Valves: Discharge valves should be placed in the fully open position.
Systems should not be operated for extended periods of time
with the discharge valves partially closed due to damaging
the valve.
SHUTDOWN PROCEDURES
If a system is shutdown for more than six months, the following is recom-
mended:
Pumps: If pit is to remain dry, then the pump can remain in the pit.
With the pump in the pit, it should be operated for fi ve minutes
once every three months. If the pit is to remain wet, the pump
should be removed and stored as noted above.
Panels: The panel should have all openings sealed to prevent moisture
and dust from entering the enclosure. Prior to restarting system,
the panel should be inspected for presence of moisture and any
loose connections.
Valves: Consult the valve/actuator supplier for information concerning
these systems components.
Repair and service should be performed by a Zoeller
Pump Company Authorized Service Station only.
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 that they can be pulled out
in case of asphyxiation. Sewage water gives off methane and hydrogen
sulfi de gases, both of which can be highly poisonous.
Installation and checking of electrical circuits and hardware should be
performed by a qualifi ed electrician.
Pump is never to be lifted by power cord.
Unit must be fl ushed and disinfected, inside and out,
prior to servicing.
GENERAL SYSTEM INSPECTION
Before the system is placed into operation, a system Start-up Report
should be conducted by a qualifi ed technician.
Wiring and grounding must be in accordance with the na-
tional electrical code and all applicable local 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 month:
• Check for proper and unobstructed fl oat operation.
• Listen for proper check valve operation.
• Duplex Units - Check for even operating times. Uneven times indicate
a defective unit, fl oat switch or control.
• Inspect the panel for any presence of moisture in enclosure, loose
connections, and general component condition. check out location
and condition of fl oat switches.
Every year:
• In addition to the monthly checks, the basin should be inspected
and cleaned. Any defective components should be replaced. Inspect
and remove any sand, debris, or mud present in the pump basin
assembly.
Every two years:
• Check insulating oil in motor and seal chambers. Inspect oil for
contaminations as follows:
• Clear oil, no burnt odor - Oil, motor and seals are in satisfactory
condition.
• Dark oil, burnt odor - Pump motor has overheated. Check the motor winding
resistance to ground. Ohm readings of 1 megohm or higher is required. If
lower readings are present, return the unit to an Zoeller Authorized Service
Station for service.
• Milky, emulsifi ed oil - Seals have failed. Unit must be returned to an
authorized service facility for service.
• Dispose of the motor insulating oil properly if replacement is re-
quired.
• Inspect power cables for damage or wear. Replace immediately if
damage or wear is detected.
• Inspect impeller for damage or wear. Replace as required by a Zoeller
Authorized Service Station.
DOUBLE SEAL PUMPS
• Double seal pumps offer extra protection from damage caused by seal
failure.
• Oil in a motor housing and lower seal cavity must be checked when
pump is serviced. If oil from the motor housing contains water or other
contamination, both seals should be replaced during maintenance.
Always replace with new factory recommended oil and service parts.
All repairs must be made by Zoeller Authorized Service Stations.
