• 1.5” flushpipe: max 360mm, min 180mm
• 2” flushpipe: max 190mm, min 100mm
Note: the cistern should be fitted as high as possible inside a WC unit. In deep WC units or wall cavities, it may be necessary to
fit a wooden batten to the rear of the unit or solid wall to move the cistern and flushpipe forwards.
IF THE CISTERN DOES NOT HAVE A FRONT CUT OUT, IT SHOULD NOT BE INSTALLED IN FRONT ACCESS FURNITURE UNITS.

c. Fit the wall mounting bracket to the centre of the installation position as shown below ensuring that the moulded arrow points
towards the wall.
d. Check that the wall mounting bracket is level using a spirit level before finally tightening the screws.
e. Hang the cistern onto the wall mounting bracket.
