OPERATION
GENERAL
Zoeller pumps are lubricated and tested at the factory prior
to shipment and require minimum pre-start-up maintenance.
Maximum operating temperature of pump liquid for standard
model pumps must not exceed 130 °F (54 °C). For longest service
life all pumps should be totally submerged on long pumping cycles
and a maximum of 1/2 hour run time per hour.
These units are not designed to handle liquids other than water
or sewage. If pump is used in water contaminated with heavy,
viscous, or abrasive materials, the warranty will be voided.
NAMEPLATE DATA
The nameplate, located on the top of pump, indicates specific
information about the construction of the pump. The model
number, and date code information should be recorded on the
front page in the “Owner’s Information” section of this manual.
SHORT TERM STORAGE
If pump is to be stored, the following is advised:
• Store pump inside whenever possible or cover with some type
of protective covering
• Tape or seal in plastic bag the terminal ends of wire leads
• Spray coat unpainted surfaces with rust inhibiting oil
• The impeller should be rotated every three months in order to
keep the seals lubricated and not develop a permanent set
If panel is to be stored, the following is advised:
• Store the panel inside whenever possible and leave in
the shipping box
• All openings shall be sealed
• Store in an upright position
• Do not stack anything on top of panel
START-UP PROCEDURE
Before placing the equipment into operation the following
checked:
• Correct pump rotation (3 Phase units only)
• Clean pit
• Panel dry and securely installed
• Floats positioned properly
• Discharge valves open
• 3/16” vent hole drilled in pipe between check valve and pump
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
• Motor overload protection is set in the panel
• After installing the pump into the containment area, with
adequate submergence, open the shut-off 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 recommends 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.
ADJUSTMENT PROCEDURE
Pumps: No adjustments are required other than assuring
correct rotation.
Panels: The motor overload protection in the panel must be set
to the F.L.A. rating on the pump nameplate (or refer to
pump data sheet).
Floats: Refer to the system drawing for desired location of
each float 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 recommended:
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
five 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.
