QLS – QUICK START GUIDE
Zoeller Pump Prefabricated Lift Station
FOLLOW ALL SAFETY GUIDELINES
Step #1
Conrm all components are included and there is no shipping damage. If you are
missing components or assume there is damage, please contact the distributor
where the lift station was purchased. Familiarize yourself with the instruction
manuals for each component (pump, controls, basin, etc.) prior to installation.
Place SYSTEM ID STICKER inside the door of the control panel for future reference.
Step #2
Conrm that the proper electrical power (for both PUMPS and CONTROLS) has
been provided to the jobsite by a licensed electrician. All wiring and conduit
must meet the NEC, local, and regional codes. For a single phase system, it is
recommended that separate incoming power sources be brought to the “pump” and the 115 volt “alarm & control”
circuits. On a three phase system, the circuits are isolated with a multi-tap transformer, therefore only one power
source need be brought to the panel.
Step #3
Properly excavate the pit being careful not to disturb any underground utilities or existing structure. Pit should be
a minimum 24” larger than the basin diameter. Make sure to adhere to all local/national building and safety codes.
Basin install requires the use of a compacted sub-base or concrete pad.
• DO NOT DROP, IMPACT, OR ROLL BASIN
• DO NOT WRAP CABLE OR CHAIN AROUND BASIN
Step #4
Measure, cut and align all inlet, electrical and discharge piping. Properly test t and glue all discharge, inlet hubs
and electrical conduit couplings. Inspect ALL connections on the exterior of the basin. Use a hole saw one inch
larger than the pipe seal size to drill into the side of the basin at the correct elevation to properly install the pipe seal
hub assembly (follow the directions on your hub, if the inlet tting provided is not a pipe seal).
Step #5
Backll pit surrounding the basin with appropriate gravel (minimum 12” from basin wall). Basin should be lled
with water prior to pouring a concrete anchor around anti-oatation device. Backll and subbase should be 1/8”-
3/4” pea gravel or 1/8”- 3/4” crushed stone. See drawing (SK 2280) on next page.
Step #6
Backll grade with gravel and ll dirt or to specifying engineer’s design. See basin drawing (SK 2280) on next page.
These guidelines and installations are to ensure that damage or premature failure to the system does not occur. The QWIK Start Guide is NOT
designed to be a replacement for all installation instructions. Safe and proper installation procedures shall be the responsibility of the installer.

Step #7
Once unit is ready for testing:
• Verify that the pit is free of ANY debris
and power cords are properly placed out
of way.
• With control panel ON, verify that pump(s)
operate manually using the HAND mode
inside the control panel.
• With control panel ON, verify that the
pump(s) operate automatically using the
AUTO mode inside the control panel.
• Third oat will activate the ALARM
BEACON on control panel on a 3-oat system.
• Fill basin with water and conrm that pumps are operating (and alternating if a duplex system) properly.
Do not run dry for more than a few seconds as this will damage the pump’s mechanical seal.
