1Installation steps
1.1 Step 1 –Excavating, bedding preparation and placing of the pumping station
•Excavate the required area by respecting the minimum
distances shown on the adjacent illustration.
•Level and compact the bedding material (H2) which
consists of Ø 0-20 mm (0-¾") gravel or sand.
•Place the pumping station on a level and stable layer of
fine gravel.
•The pumping station must be accessible at all times and
must be 50 mm (2") above the surface of the landscaped
lot.
•A maximum of two (2) PSR-140 risers is allowed.
1.2 Step 2 –Pipe connections
•Connect the previous tank to the pumping station using a pipe that complies with the regulations. The
pipe must have a minimum downward slope of 2% towards the pumping station.
•Connect the 4” (100 mm) SDR-35 exit to the following tank using 4” SDR-35 pipe. The pipe must have
a minimum downward slope of 2% towards the pumping station.
•Connect the 2” (50 mm) PVC pipe exiting the pump to the phosphorus removal equipment with either
a 2” PVC SCH80 pipe or a 2” flexible pipe. The pipe must withstand at least 700 kPa (100 PSI) of
pressure and is suitable for underground applications.
•Connect the 2” (50 mm) PVC pipe coming from the phosphorus removal equipment with either a 2”
PVC SCH80 pipe or a 2” flexible pipe to the 2” inlet pipe of the pumping station. The pipe must
withstand at least 700 kPa (100 PSI) of pressure and is suitable for underground applications.
•A vent must be installed on the pumping station.
•The pipes must be installed in a way that they drain by gravity.
•Precautionary measures against freezing must be taken to protect the pipe connecting the pumping
station to the treatment system.

1.3 Step 3 –Riser installation (if required)
When the pumping station installation requires extension risers, proceed as follows:
•Use PSR-060 (150 mm, 6") risers or PSR-140 (355 mm, 14")
risers if required. Maximum height of risers: 710 mm (28").
•Clean the access rim of the pumping station (where 4 holes
were perforated to insert the lag screws).
•Install the watertight seal on the pumping station’s access
rim.
•Align the holes of the riser with the holes of the pumping
station.
•Insert the washers in the lag screws provided with the riser
and screw them in place to firmly fix the riser.
1.4 Step 4 –Electrical connections
The electrical connections should be executed by an electrician. IF YOUR LOCAL ELECTRIC CODE
ALLOWS IT, remove the connector plugs from the float and pump wires by cutting the ends and perform
the electrical connections using the supplied waterproof screw-thread wire connectors in order to ensure
the water does not affect the electrical circuit. The use of waterproof screw-thread wire connectors is
mandatory with the electrical junction box. Note that the junction box must be installed outside of the
pumping station, on a post above the ground surface, to prevent the box from being submerged and also
to have access to the box at all times.
To wire the system, two (2) in-ground double strand supply cables are required. It is preferable to protect
the wires with the appropriate piping before burying them. To pass wires through the pumping station’s
wall, use watertight bulkhead union fittings.
Important: before the pumping station start-up, check if the float holding device for the transportation
has been removed. Also, check if the floats are ready and in the proper position for operation.
1.5 Step 5 –Final backfill
•Close the lid so nothing falls into the pumping station during
backfill.
•Isolate the pipes if required.
•Backfill the pumping station and the pipes with material void of
any organic matter, impervious soil, stones, debris, particles
larger the 20 mm (¾") in diameter or any other object that could
damage the pumping station.
•The backfill material must be placed with care and not dumped
(do not compact with bulldozer).
•Allow space for ground cover and make sure the lids are at least
50 mm (2") above the surface of the landscaped lot.
•Finalise the backfill with a layer of soil that encourages
vegetation growth.

2Pumps performance curves
The figure below presents the performance curves of the
different pumps used in the pumping stations (red line –PSA-
240H)
Note that these curves were obtained with clear water, the
pumps might not perform as well with wastewater. If you
have questions about the interpretation of these curves,
please do not hesitate to contact Premier Tech Aqua.
3Pumping station start-up and adjustment
Take the pump out of the pumping station by previously removing the fastener that ties it to the reservoir
(do not leave the fastener in the pumping station) and perform a visual inspection. Then, place the pump
in the reservoir and connect the water outlet pipe using the cam coupler. Take the float tree out of the
pumping station. Remove the fastener holding the floats for transportation purposes (do not leave the
fastener in the pumping station). Make sure the floats are properly attached to the float tree and adjusted
as specified in the following sections. Then, attach the float tree to the pumping station by placing the
lower end in the cavity found at the bottom of the reservoir and attach the upper end to the fastener on
the side wall of the pumping station.
What you must know for all the pumping stations:
•Make sure the bottom of the pumping station is clean and void of any
objects that could damage the pumping station.
•Adjust the cable’s length on the On/Off float to obtain the wanted dosage
for your application.
•The minimum water level in the pumping station is of 185 mm (7¼").
4Maintenance
The pumping station has mechanical components; therefore, it is preferable to conduct an annual
preventive inspection. Furthermore, it is important to comply with the regulations regarding the septic
tank emptying in order to prevent large particles from escaping the septic tank and blocking the pump.
We strongly recommend you empty your pumping station at the same time as your septic tank.
If you have any questions or comments, do not hesitate to
contact Premier Tech Aqua at 1 800 632-6356.
