Pre-Installation Checks
When planning the plumbing for your Bath and Shower Mixer installation, it is recommended that the following
checks are undertaken
• The products are supplied with the hot inlet on the left and cold on the right when viewed from the front. The
connection of hot and cold water must be supplied to the appropriate inlet for these products to work
correctly (the hot side is marked with red mark and the cold with blue!)
• Ensure all pipe work has been thoroughly flushed before any installation takes place. Any debris in the
system will impact on the taps performance and may void warranty.
• Ensure that there is sufficient space to install the product without hampering its operation.
• The levers are fixed by a screw located under the coloured indice on top of the levers. Access to this is
required for removing both handles during maintenance and servicing
