Installation Guide

The underground electrical service cable for the Service Pro control center should be installed by the tank delivery truck driver
or electrician as soon as the Singulair tankage has been installed in the prepared excavation. Usually it is best to begin with
the underground service cable so that backfilling of the Singulair tankage and influent sewer line is not delayed. The information
contained in these instructions is not intended to be a complete electrical installation reference, as code requirements vary
according to geographic area. Always insure safe working procedures are followed whenever electrical work is performed on
the Singulair system.
UNDERGROUND ELECTRICAL
CABLE INSTALLATION
To insure proper electrical system protection and
uninterrupted service to the Singulair aerator and control
center, be sure to follow these instructions carefully.
Always double check all work before leaving the job site.
1. Electrical work must be
performed in accordance
with the latest edition of the
National Electrical Code as
well as all applicable local
codes.
2. Underground electrical
service cable used with the
Singulair system must be
UL and CSA approved,
type UF, #14/2 AWG
minimum and must have a
full-size center ground.
Larger cable is required if
the underground service
needs to be run more than
80 feet. Consult your
electrician for details.
3. The underground cable
installation must be
unspliced from the location
of the Service Pro control
center into the aerator mounting riser above the
aeration chamber of the Singulair tank.
4. Install a watertight conduit fitting into the power cable
entrance in the side of the aerator mounting riser. Insert
the free end of the power cable through a pre-formed
two foot by one foot conduit ell, then into the watertight
conduit fitting in the power cable entrance of the aerator
mounting riser. Guide the power cable up into the aerator
mounting riser. Pull enough cable through the riser to
reach thirty-six inches above the riser opening. Coil
and secure the cable in the mounting riser so that it will
not hang down into the tank while the system is being
filled with water.
5. Lay the conduit ell with cable directly across the top
and down the tank side. Do not allow the power cable
to be laid across the end of the tank or any removable
access cover. Insure the conduit and cable entrance
openings are sealed.
6. Check the excavation and sewer line trench to be sure
they are free of debris, rocks and any sharp or
abrasive objects.
7. Uncoil the electrical service
cable into the excavation
and influent sewer line
trench. Leave sufficient
slack in the cable so
that it will not be stressed
or pulled tight during
backfilling or settling.
8. Backfill around the
underground electrical
cable with fine granular
material.
9. The underground electrical
cable should have at least
two feet of earth cover. If
the proposed finished
grade will not permit this
coverage, the cable should
be installed in approved
conduit from the tank to the
building foundation.
10. Always encase the
electrical cable in conduit any time it is above finished
grade. Route the conduit and cable as directly as
possible to the control center mounting location.
INSTALLATION OF
ELECTRICAL CONTROL CENTER
Although the aerator is not installed until system start-up,
the control center should be wired for operation when the
tank and underground electrical cable are installed. The
control center should be located so the red warning light
can be seen and the audible alarm heard. The mounting
location should minimize exposure to direct sunlight,
