General
We recommend that the product be brought into the room where it is to be installed
and left to acclimatise to room temperature, this will reduce the possibility of
condensation on electronic components.
The shower works best when water supply conditions are stable and within the
specications, refer to section 'Specications'. If the supply conditions fall outside
the specications, the shower may go into a safe shut down condition.
DO NOT connect the outlet of the shower to any tap, on/o󰀨 control valve, trigger
operated showerhead or any other showerhead other than those specied for use
with this shower. This could cause scalding or severe damage to the product and
will invalidate the guarantee. Only Kohler Mira recommended showerheads, shower
hoses and accessories must be used.
If pipework and/or electrical cables enter the shower from the rear through a hole in
the wall, provision must be made to prevent water ingress back into the wall structure.
Route cable and pipe supplies via the cut outs moulded in the case and cover.
DO NOT perform any unspecied modications to the shower or its accessories.
Drilling xing holes or making water or electrical entry points outside of the showers
designed areas can lead to uncontrolled water ingress. This could cause re,
electrocution or damage to the product and will invalidate the product guarantee.
When servicing only use genuine Kohler Mira replacement parts.
DO NOT increase the size or cut alternative pipe / cable entry points as water ingress
into the product may occur.
After completing the installation be careful when cleaning. Many household and
commercial cleaners, including tile cleaners and hand/surface cleaning wipes contain
abrasives and chemical substances that can damage plastics, plating and printing
and should not be used. These nishes should be cleaned with a mild washing up
detergent or soap solution, and then wiped dry using a soft cloth.
