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 a hole to dimensions of 495mm from base of chamber to hole
centre, central location of the discharge flat surface fascia, noting on the above drawing for step
arrangement.
b) Affix 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 2no. Male Threaded Adaptors (part list position no. 1) and screw
tightly into the Pumps Integral Non-Return Valve female threaded outlet connection point.
d) Position the Pumps within the chamber as per above diagram. Check that the Pump Float Arms are
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 Tee
Piece (8) to be positioned above and between the Male Threaded Adaptors (1), taking into your
measurement the length of pipe inserted into the fittings (do not use solvent glue at this stage).
g) Measure and cut a length of link pipe for the Tee Piece (8) and Elbow (2) connections, noting that
these fittings should be placed directly together (do not use solvent glue at this stage).
h) Measure and cut a length of link pipe for the Elbow (2) and Socket Union (3) connections, noting that
these fittings should be placed directly together (do not use solvent glue at this stage).
i) Measure and cut a length of vertical Pipe required between the placed Socket Unions (2) and Male
Threaded Adaptors (1), taking into your measurement the length of pipe inserted into the fittings (do
not use solvent glue at this stage).
j) 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.
k) 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.
l) 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 fittings kit.
