Maintenance - Zoeller 600 Serie Manuel Du Propriétaire

Once the above has been verified 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 submer-
gence, open the discharge valve fully. Start the unit using manual controls.
If flow 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 qualified 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 Pump Company requires completing a Start-up Report
(ZM1074) whenever a system is started for the first time or after a system has
had a significant change take place (i.e. pump replacement, overhaul, etc.). A
copy of the Start-up Report should remain with the system for future reference.
Repair and service should be performed by a Zoeller Authorized
Service and Warranty Center 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 sulfide gases,
both of which can be highly poisonous.
Installation and checking of electrical circuits and hardware should be performed
by a qualified electrician.
Pump is never to be lifted by power cord.
Unit must be flushed 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 qualified technician.
Wiring and grounding must be in accordance with the national
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.

Maintenance

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 float operation.
• Listen for proper check valve operation.
• Duplex Units - Check for even operating times. Uneven times indicate a
defective unit, float 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 float
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 and Warranty
Center for service.
• Milky, emulsified 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 required.
• 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 and Warranty Center.
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 and Warranty Centers.

three months. If the pit is to remain wet, the pump should be removed
and stored as noted above.
from entering the enclosure. Prior to restarting system, the panel should
be inspected for presence of moisture and any loose connections.
