Operation
GENERAL
Zoeller pumps are lubricated and tested at the factory prior to shipment and
require minimum pre-start-up maintenance.
Maximum liquid temperature of a continuous operating pump liquid for this
model pump must not exceed 104 °F (40 °C). For longest service life all pumps
should be totally submerged on long pumping cycles. Maximum submerged depth
is 50' (15.2 m).
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, date code, and serial number
information should be recorded on the front page in the “Owner’s Information”
section of this manual.
If the pump is repaired in the field, its explosion
proof rating may be voided.
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 six 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 should be checked:
• Correct pump rotation (3 Phase units only).
• Clean pit.
• Panel dry, securely installed and properly sealed.
• Floats positioned properly.
• Discharge valves open.
• 3/16” (4 mm) 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 in an intrinsically safe 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 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.
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. 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. Sys-
tems 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.
