3. Site preparation and installation
3.1 Advisory
It is important to note that these instructions are for guidance only and it is the installer’s responsibility to satisfy
themselves that the installation procedure is in accordance with the site conditions and good building practice, to
eliminate any potential damage to the system either during or after installation. The installer should also satisfy themselves
that the system can be install in conjunction with these guidelines, prior to work commencing.
The chamber is manufactured from polyethylene and as such is extremely robust. However, as with any preformed
chamber they are susceptible to oatation and hydrostatic pressures exerted in high water table conditions.
Only qualied personnel should carry out the installation in accordance with the latest IET wiring regulations BS7671. All
works should be in line with the Health and Safety at Works Act 1974.
Please read these instructions in full, prior to commencement of installation. If you are unsure on any point then ask for
advice before proceeding. Our technical help desk is available on 01442 211554 from 08:30–17:30 Monday to Friday.

First select a suitable location for the pump ensuring that the oat arm is not obstructed by for example the
chamber wall, inlets etc, at its optimum reach. Remove the nut located in the pump switch and push the oat
arm into place ensuring that the nut is securely replaced. Prior to installing the internal pipe work please check
the Non-Return Valve is securely xed to the pump outlet and ensure that the ap opens in the direction of the
ow.
a) Using a 1¾” Hole Saw (44mm), cut a hole to dimensions of 495mm from base of chamber to hole
centre, central location of the discharge at facia, noting on the above drawing for step arrangement.
b) Afx the supplied 1¼” PVC Tank Connector (part list position no. 5), with the male thread being fully
externally located and placing the gasket seal internally between the internal locknut and chamber
wall. Tighten Tank Connector PVC screwed lock nuts.
c) Apply PTFE tape to the supplied Male Threaded Adaptor (part list position no. 1) and screw tightly
into the Pump Integral Non-Return Valve female threaded outlet connection point.

d) Position the Pump within the chamber on the high step, making sure the Male Threaded Adaptor
is in direct line with the installed Tank Connector. Check that the Pump Float Arm is free from any
obstruction at its optimum reach.
e) Place the Socket Union (position no.3) over the plain end of the Tank Connector (do not use solvent
glue at this stage).
f) Measure and cut a length of horizontal Pipe required between the placed Socket Union (3) and Elbow
(2) to be positioned directly above the Male Threaded Adaptor (1), taking into your measurement the
length of pipe inserted into the ttings (do not use solvent glue at this stage).
g) Measure and cut a length of vertical Pipe required between the placed Elbow (2) and Male Threaded
Adaptor (1), taking into your measurement the length of pipe inserted into the ttings (do not use
solvent glue at this stage).
h) Chamfer, clean and dry the connection edges of the PVC lengths, using an appropriate PVC Solvent
Cleaning Fluid, making sure these areas on the pipe and within the tting are free from any debris/
dirt.
i) Check all the pipework is in place correctly before applying plenty of PVC Solvent Cement on
required connections, wiping away any excess that may become visible with a clean cloth.
j) For connection of the external discharge pipework, you will be left with a 1¼” PVC male thread on
the outside of the chamber. We recommend that you use 1¼” Class E PVC Pressure Pipe, but should
the installer wish to use 36mm OD Solvent Weld Waste Pipe (white), a PVC 1¼” Coupling Female TH/
TH (6) and a 32mm Male Iron (7) is supplied within the ttings kit.
To apply these connections, apply PTFE tank to the male threads of the Tank Connector and Male
Iron. Screw the 1¼” Coupling Female TH/TH (6) onto the Tank Connector, following the same process
for the Male Iron into the Coupling.
Connection to be made with 36mm OD Solvent Weld Waste Pipe into the Male Iron would be as per
point g) and h) as above.
2. Select a suitable location for the pumping station. It is extremely important to site the system with permanent
access in mind for routine maintenance of the system.
3. Prepare the chamber for all connection, incoming pipe/s (inlet/s and cable duct). To do this you must select the
location and drill the appropriate sized inlet/s and cable duct for the connections (see Section 7 Accessories’
for inlet and cable duct rubber seals).
4. A reinforced waterproof concrete sump must be formed for the chamber to be installed within. This will
ensure that any pressure present is not transferred onto the chamber itself. Furthermore, when constructing
the reinforced waterproof concrete sump it is important that adequate space is made for connections to the
chamber e.g. inlet/s, cable ducts and discharge. Consideration must also be made regarding the depth and
orientation of all connections to ensure that they line up with the chamber.
It is imperative that you consult with a structural and waterproong engineer when designing the reinforced
waterproof concrete sump ensuring that it allows for the anticipated pressures and that they are not transferred
onto the chamber.

5. In all instances, the chamber MUST be positioned on a at, level, concrete base of dimensions sufcient to
fully support the base of the chamber. Once the reinforced waterproof concrete sump has been formed, lay
a 100mm mass concrete within your reinforced waterproof concrete sump, carefully position the chamber
onto the WET concrete base ensuring that no loose debris is inadvertently knocked onto the base, under the
chamber during this procedure. Push the chamber into the wet concrete ensuring that the concrete is fully
imbedded into the bottom of the chamber. Position it such that the inlet/s, cable duct and discharge pipe work
are correctly aligned.
6. Once the chamber is positioned, connect all pipes (inlet/s, cable duct and discharge) to the chamber.
7. Whilst the concrete base is still WET backll the chamber with a mass concrete. The concrete must be evenly
poured around the chamber ensuring that no voids are left within the concrete. Care must be taken to ensure
that any pipes (or other connections) made, are not damaged. During the concrete pour, ensure that the
chamber is vertical (by use of a spirit level across the chamber’s opening). The chamber MUST be ballasted
with water at the same rate as backlling such that the level difference between the water and the backll does
not exceed 150mm at any time.
Please ensure that when pouring the concrete backll, suitable steps are taken to prevent the concrete entering
the chamber and any connected pipework.
8. The system is supplied with an access cover, this is loose and should sit directly above the top of the chamber
access shaft. Please note that the chamber is only suitable for installation to a maximum of 300mm deeper than
supplied from nished oor level.
9. Please note that the ballast water inside the chamber should not be removed until the backll has fully cured.
10. It is recommended that an external gate valve (see Section 7 Accessories) be installed on the discharge line
above slab level should the vertical lift exceed 3 meters.
11. It is extremely important that once the chamber has been installed, before the pump is installed, the system is
ushed through and all sand, silt, rubble and general debris removed from the chamber.
FAILURE TO DO THIS WILL INVALIDATE THE WARRANTY ON THE PUMPS.
12. Install the pumps and water level monitoring cables and draw these cables through the cable duct back to the
control equipment/electrical supply.
13. Commission the pumping station. A commissioning service is available, simply contact us on 01442 211554 for
further information.

required connections, wiping away any excess that may become visible with a clean cloth.
j) For connection of the external discharge pipework, you will be left with 2no. 1¼” PVC male thread
on the outside of the chamber. We recommend that you use 1¼” Class E PVC Pressure Pipe, but
should the installer wish to use 36mm OD Solvent Weld Waste Pipe (white), 2no. PVC 1¼” Coupling
Female TH/TH (6) and 2no. 32mm Male Iron (7) is supplied within the ttings kit.
2. Select a suitable location for the pumping station. It is extremely important to site the system with permanent
access in mind for routine maintenance of the system.
3. Prepare the chamber for all connection, incoming pipe/s (inlet/s and cable duct). To do this you must select the
location and drill the appropriate sized inlet/s and cable duct for the connections (see Section 7 Accessories’
for inlet and cable duct rubber seals).

4. A reinforced waterproof concrete sump must be formed for the chamber to be installed within. This will
ensure that any pressure present is not transferred onto the chamber itself. Furthermore, when constructing
the reinforced waterproof concrete sump it is important that adequate space is made for connections to the
chamber e.g. inlet/s, cable ducts and discharge. Consideration must also be made regarding the depth and
orientation of all connections to ensure that they line up with the chamber.
It is imperative that you consult with a structural and waterproong engineer when designing the reinforced
waterproof concrete sump ensuring that it allows for the anticipated pressures and that they are not transferred
onto the chamber.
5. In all instances, the chamber MUST be positioned on a at, level, concrete base of dimensions sufcient to
fully support the base of the chamber. Once the reinforced waterproof concrete sump has been formed, lay
a 100mm mass concrete within your reinforced waterproof concrete sump, carefully position the chamber
onto the WET concrete base ensuring that no loose debris is inadvertently knocked onto the base, under the
chamber during this procedure. Push the chamber into the wet concrete ensuring that the concrete is fully
imbedded into the bottom of the chamber. Position it such that the inlet/s, cable duct and discharge pipe work
are correctly aligned.
6. Once the chamber is positioned, connect all pipes (inlet/s, cable duct and discharge) to the chamber.
7. Whilst the concrete base is still WET backll the chamber with a mass concrete. The concrete must be evenly
poured around the chamber ensuring that no voids are left within the concrete. Care must be taken to ensure
that any pipes (or other connections) made, are not damaged. During the concrete pour, ensure that the
chamber is vertical (by use of a spirit level across the chamber’s opening). The chamber MUST be ballasted
with water at the same rate as backlling such that the level difference between the water and the backll does
not exceed 150mm at any time.
Please ensure that when pouring the concrete backll, suitable steps are taken to prevent the concrete entering
the chamber and any connected pipework.
8. The system is supplied with an access cover, this is loose and should sit directly above the top of the chamber
access shaft. Please note that the chamber is only suitable for installation to a maximum of 300mm deeper than
supplied from nished oor level.
9. Please note that the ballast water inside the chamber should not be removed until the backll has fully cured.
10. It is recommended that an external gate valve (see Section 7 Accessories) be installed on the discharge line
above slab level should the vertical lift exceed 3 meters.
11. It is extremely important that once the chamber has been installed, before the pump is installed, the system is
ushed through and all sand, silt, rubble and general debris removed from the chamber.
FAILURE TO DO THIS WILL INVALIDATE THE WARRANTY ON THE PUMPS.
12. Install the pumps and oat switch and draw these cables through the cable duct back to the control equipment/
electrical supply.
13. Commission the pumping station. A commissioning service is available, simply contact us on 01442 211554 for
further information.
