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.
