Pre-installation
Installation must be undertaken in accordance with the PCA (Plumbing Code of Australia) , AS/NZS3500.1 and AS/
NZS3500.2. Where multiple WC’s may be installed, correct hydraulic water supply sizing must be undertaken to ensure
that each ushing device servicing each WC is able to operate correctly under probable simultaneous demand. A minimum
water supply pressure of 300kPa is required for ushing device installation along with a minimum 25mm Cu or equivalent
water supply line size for single ushing device installation only.
Pan is wall faced and should preferably be xed to a masonry wall with suitable wall anchors provided by others.
Flushing device should be:
Fowler Tasman Mk 2 [or Stylus Symphony] cistern
Caroma Invisi II [inceiling mount recommended]
RBA’s ‘Nautilus’ Dual Flush Valve Incl Large Mounting Plate [see RBA1882-100-001]
Installation
1. Check supplied toilet against rough-ins provided in the installation instructions.
2. Remove access panels and place them in a safe area. Make sure to identify the access panels to the toilet they are
removed from.
3. If not pre-formed, make sufcient penetrations through the wall and/or oor, as determined from the drawing, to allow
for the 100mm waste pipe and ush pipe as provided by the cistern or ush valve manufacturer.
a. If rear xed, M12 xing rods [by others] to pass through.
b. If front xed, use suitable wall anchors [by others] in the rear and oor of the toilet.
4. Determine oor mounting location by mocking up.
5. For P-trap congurations, t a 100mm pan collar to the outlet with sufcient 100mm pipe to extend through the wall.
Alternatively the waste and ush pipes may be pre-plumbed and the pan pushed onto the pipework.
6. For S-trap congurations, location of oor penetration should be centred 220mm from nished wall.
7. Similarly t a 55mm Kee seal [by others] to the pan inlet with sufcient pipe, as provided by the cistern manufacturer,
to extend through the wall.
8. Push the pan into position and secure the pan to the wall & oor [xings by others].
9. Make the necessary connections to the waste and install the cistern and connect according to the manufacturer’s
instructions.
10. Check for leaks and correct ush volumes, 6 litres full ush and 3 litres half ush.
11. Unscrew plug bolts and t the seat to pre-drilled holes and replace the access panels.
