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° C (54° F). For longest service life, all pumps
should be totally submerged on long pumping cycles and have 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 indoors 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 indoors 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, check the following:
• Correct pump rotation (3 phase units only)
• Clean pit
• Panel dry and securely installed
• Floats positioned properly
• Discharge valves open
•
5 mm (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
• 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 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_Eb) 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
P
umps: No adjustments are required other than assuring correct
rotation.
Panels: The thermal overloads 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.
SHUT-DOWN PROCEDURES
If a system is shut down for more than six months, the following
is recommended:
P
umps: If pit is to remain dry, 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.
