NOTICE TO THE CONTRACTOR
This lift station and controls will be owner specified, contractor furnished, and delivered to the
site. The successful bidder will furnish all other materials and labor to install the lift station and
its controls and ensure its proper operation. It is the contractor ’s responsibility to install the lift
station per this plan as indicated and make all connections, plumbing and electrical, in an
approved manner as required by this drawing and local codes. The contractor ’s responsibilities
are as follows: receiving the lift station and off loading, excavation and setting, all plumbing
connections (inlet, vent, wet well to valve box, force main run thereafter to the point of city
connection of receiving manhole or force main), all electrical conduit from the wet well to control
panel, provide proper backfill and compaction procedures. The contractor will be required to
lower the pumps into place and perform the system start up . A startup procedure form will be
provided and it must be filled out and returned to the lift station supplier prior to the owners
possession date via fax or email. Fax #951-678-7163 email- info@psipumps.com
Receiving / offloading instructions and preparation before setting
Receiving the lift station
Inspect the entire shipment for damage before the lift station is taken off the truck. If there is damage, note as
specifically as possible including clear photos of damage on the bill of lading as to any damage, then offload.
Contact the shipper at once and have the bill of lading with you. Call 800-358-9095 for further instructions.
Preparing the lift station
The lift station has been made ready to travel several hundred miles. The main wet well will contain bracing that
needs to be removed before it is set in place. The lift station is to remain horizontal and on the pallet until the day
it is to be set in place. On that day open the main hatch and remove the control panel, basin fittings, transducer
housing and float tree. Remove all lumber bracing, wire ties and duct tape. Check all flange bolts and tighten as
necessary. Check all flange bolts in the valve box as well, tighten as necessary.
Setting the lift station
The best way to set the wet well is to use two cinch straps of equal length. Place the straps right under the rim so
they will tighten as the wet well is lifted. If the straps are properly positioned the wet will hang level and secure. If
you have experience in this area use your own discretion.
BASIN INSTALLATION INSTRUCTIONS
1. Excavation Dimensions: Excavation shall be 6" deeper than the depth of the basin, below finish grade
and done in such a manner as to preserve the undisturbed state of bearing soils at the bottom. Diameter
of excavation shall be sufficient to allow for necessary external pipe connections with a minimum 12"
greater than the basin diameter.
2. Backfill Materials:
a. The backfill materials shall be in inert, free flowing granular soil such as clean sand or gravel (1/4"
mesh or finer).
b. Acceptable backfill includes “stone dust” from rock crushing operation provided it possesses all
the characteristics of free flowing sand and contains less than 20% by weight passing the No. 200
mesh sieve. Soil fines must be non-plastic.
c. Silts, clays, organic soil, granulated cinder, slag and similar corrosive material shall not be used.
Backfill shall be free of organic material, loam, trash, snow, ice, stones, rubble, etc.
3. Pipe Connections: Make necessary pipe connection in approved manner. Note: connection may be
threaded, caulked lead joints or other specified approved method,
NOTE: BACKFILL SHOULD BE DONE AS SOON AS THE WET WELL IS SET AND LEVEL.
4. Backfill as follows:
a. If the hole is flooded, the water level shall be pumped down to a maximum depth of 3 inches before
preparing the bed and placing the basin. Water level shall be maintained below bottom of the
basin until the excavation is backfilled and until there is adequate safety against uplift.
b. The first layer of backfill is the base for the basin and shall be at least 6" thick.
c. Place the basin on the bed and after aligning and leveling, push additional fill under and around
the basin and compact by tamping to a uniform depth of 12" around the basin. This insures that
the established grade and level of the basin will be maintained during remainder of the backfilling
operation.
d. Backfill shall be continued in one foot layers with specified sand backfill uniformly distributed
around the basin and compacted around the basin.
e. Concrete encasement may be used in lieu of backfill as described above, if the whole excavation
does not exceed 12" in diameter larger than the basin to be installed.
5. Cover: The cover shall be bolted in place with an approved gasket material to effect a gas-tight seal.
Instructions to remove a reinforcing rib to install the inlet
This procedure is required only if the gravity inlet lands on a rib!
Measure the length of the rib to be removed. Using a sawzall cut the rib lengthwise on the top and bottom of the
rib. Keep in mind that the rib is hollow. Make the end cut between the top and bottom of the rib. Note: take care
not to damage the underlying wall of the wet well. Remove the cut rib and the foam underneath. Use a circular
sander to reduce the ridges left by the removal of the rib. What should remain is the uniform wall thickness of the
wet well where the inlet is to be installed. Note: it is ok to remove a little more rib than to just fit the inlet fitting.
Six inches on each side of the inlet is fine.
INSTALLATION OF THE FLOAT TREE AND THE SUBMERSIBLE TRANSDUCER HOUSING
Installing the submersible transducer housing and transducer
(The transducer is very sensitive to shock - be very careful with it!)
The housing has been cut to fit prior to leaving the factory. Slip the bottom of the housing over
the pre-installed strainer at the bottom of the wet well. At the top under the small hatch there will
be a clamp holding a short 2” pipe. Discard the short pipe and use the clamp to secure the top of
the housing. Make sure the housing is plumb.
The transducer will be located behind the outer door of the control panel. Remove all packing
material and slowly lower the transducer into the housing until it reaches the bottom, then pull
back 2” of cable, loop the cable over the housing and secure with the wire ties provided, use two.
The cable is color coded and will correspond with the connection locations in the control panel.
The clear tube will connect to the aneroid bellows in the control panel.
Installing the float tree
The floats have been preset - no adjustment is necessary. Lower the float tree through the small
hatch on the main wetwell cover. Insert the bottom end of the tree into the floor flange installed
at the bottom of the wetwell. The short 1” pipe in the clamp will be discarded. The clamp will be
used to secure the top of the float tree. Once installed, rotate the float tree to ensure free
movement of the floats. The floats need to float up and down without touching anything. The
tags on the floats will correspond with the connection locations in the control panel - do not
remove the tags.
