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 3.4 m
higher than the unit.
3.14 If the unit is to be installed within
furniture or cupboards, or boxed
in, allow space for motor ventilation
through the top cover leaving at
least 90 mm between the unit and
any shelf/boxing.
3.15 If either a dishwasher or washing machine
are to be used, they must always be fitted
using the top connectors.
