Notes on Eco Plus 1F Installation
Cistern may be installed in stud
framing or face mounted to
masonry. Minimum spacing of
623mm between studs. Studs
must be able to support the
applied loads. Refer to project
engineer/details.
The waste outlet pipe is 90mm
OD, therefore in 90mm cavity
installations, accurate alignment
of the front face of the mounting
bracket with the front face of the
studs is critical.
Where the waste pipe is to
penetrate a concrete slab floor, it
is suggested that core drilling be
carried out where a high degree of
alignment accuracy is required.
Allow for screed and tile thickness
where applicable in all height
calculations.
For the correct mounting of
flushing plates, the total thickness
of wall linings (i.e. total of lining +
tiles + adhesive) must be within
a specified range. Refer to the
following details.
