3 INSTALLATION
INSTALLATION GUIDELINES
3.11 Always use smooth bends or
2 x 45 o bends. Do not use 90 o
elbows.
3.12 You must install vertical pipework
first. Diagonal runs are not
permitted. Connection to the soil
discharge pipe must be with a 45 o
inclined connection.
3.13 If the discharge is lower than the
unit, to prevent water siphoning from
the outlet pipe, an air admittance
valve must be used (not supplied)
capable of withstanding 6 psi, and
fitted to a vertical vent pipe at least
1.4 m higher than the unit..
3.14 Unit must be placed directly behind
the WC.
3.15 Do not connect to washing
machines or dishwashers.
3.16 Ensure that the total flow drained at any
given time never exceeds the total
pumped flow from the unit, taking
into account the height and length of the
outlet pipe. For instance,
- At 5 metres outlet head, the outlet flow
is 23 l/min.
- At 2 metres outlet head, the outlet flow
is 85 l/min.
3.17 Always ensure full access to the unit is possible for maintenance.
