First select a suitable location for the pumps ensuring that 1no. pump is positioned on the base of the chamber
and 1no. pump is positioned on the raised section. It is also essential to position the pumps so the float arms
are not obstructed by for example the chamber wall, inlets etc, at their optimum reach (see diagram above).
Remove the nut located in the pump switch and push the float arm into place ensuring that the nut is securely
replaced. Prior to installing the internal pipe work please check the Non-Return Valves are securely fixed to the
pump outlets and ensure that the flap opens in the direction of the flow.
a) Using a 1¾” Hole Saw (44mm), cut 2no. holes to dimensions of 495mm from base of chamber to
hole centre, tank connector hole centres of 60mm from centre of the discharge flat surface fascia,
noting on the above drawing for step arrangement.
b) For the primary pump to be located onto the higher step - 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.
c) 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.
d) Place the Socket Union (position no.3) over the plain end of the Tank Connector (do not use solvent
glue at this stage).
e) 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 fittings (do not use solvent glue at this stage).
f) 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 fittings (do not use
solvent glue at this stage).
g) For the secondary pump to be located on the lower step - Follow above steps b) through to f) until
complete.
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 fitting 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 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 fittings 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).
