Pumping stations PSA-240/H
Item # 183036
4. Installation steps
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.
STEP 2 – Pipe connections
PSA-240 and PSA-240H pumping stations:
•
Connect the septic tank or other equipment to the pumping station using a pipe that complies with the regulations. Relier la fosse
septique au poste de pompage avec une conduite conforme aux normes applicables. The pipe must have a minimum downward
slope of 2% towards the pumping station.
•
Connect the pumping station to the inlet pipe of the Ecoflo biofilter or to the required treatment system using either a flexible 38 mm
(1½") Ø pipe for the PSA-240 or a flexible 50 mm (2") Ø pipe for the PSA-240H that can withstand at least 700 kPa (100 PSI) of
pressure and is suitable for underground applications.
•
In the case of an Ecoflo biofilter installation, run a rigid 100 mm (4") Ø ventilation pipe between the pumping station and the biofilter.
A 100 mm - 38 mm (4" - 1½") Ø adaptor (Item I identified in section 2.2) is provided to complete the connection. This adaptor must
be glued at ± 45º from the horizontal, depending on the angle at which it is easiest to install. Important: always connect the 38 mm
(1½") Ø pipe under the 100 mm - 38 mm (4" - 1½") Ø adaptor to break the pump’s flow before the eflluent penetrates the
biofilter. (Refer to the illustration PSA-240 pumping station before an Ecoflo biofilter in section 2.3).
•
If the distance between the pumping station and the biofilter is greater than 20 m (70'), it is preferable to equip the biofilter with its
own ventilation duct instead of connecting the duct to the pumping station.
•
The pipes must be installed in a way that they drain by gravity.
•
Precautionary measures against freezing must be taken in order to protect the pipe connecting the pumping station to the treatment
system.
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.
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.
