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 grinder pumps must 
not exceed 130 °F (54 °C).

These units are designed for intermittent duty sanitary sewage 
applications.  If pump is used to dewater areas or pump liquids with 
heavy or abrasive materials, the warranty will be voided.

NAMEPLATE DATA

The nameplate, located on the side of the 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

Do not install pump until electrical power is available and system 
is operational.

 

 

When not in use, the pump should be stored and 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:

•  Clean pit.

•  Pump, float switches, electrical cables and junction box are dry and 

properly installed.

•  Electrical boxes dry, sealed 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 and control floats properly installed and voltage 

verified.

•  Conduit connections to panel and junction box are properly sealed.
•  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  

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. 

ADJUSTMENT PROCEDURE

Pumps:  No adjustments are required.
Floats:   Refer to the system drawing or to the panel wiring schematic 

for the desired location of each float switch setting.

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.
