Installation Manual
Water Regulations Requirements :
It is important to ensure that the water supplies to your taps and mixers are connected in
accordance with the water regulation (WRAS) requirements and good plumbing practice.
It is good plumbing practice that the supplies of hot and cold water to the Bathroom fitting should
be equal (balanced) pressure in order to provide a consistent flow. Supplies should be from a
common source, either mains or tank fed. If supplies are not equal pressures then a Non Return
Valve ( Check Valve ) should be fitted on the hot inlet.
It is our recommendation and good plumbing practice that a service valve should be installed in the
inlet supply lines to allow isolation of the Bathroom fitting.
1. Make sure both Hot and Cold supplies have been isolated and drained.
2. Rotate the spout and body so the tap is facing forwards. The spout screw on the tap indicates
the rear of the body. Typically the hot water should be on the left-hand side of the tap.
Loosely position the tap with the tail pipes to check if any alteration to the existing pipework is
required, if this is the case do this now. You must thoroughly flush the hot and cold pipes, before
installing the tap to ensure that the supply is free of any debris.
Tools required.

Care and Maintenance
Important: When joining any screw connections always use PTFE tape and ensure the joints are
fully tightened. Once the tap is installed always check the entire installation for leaks.
Your tap may require non-return valves to suit your water system or to conform to local water
Bylaws.
Once the tap has been installed turn both the hot and cold water on, thoroughly flush any small
particles that may have been dislodged during the installation of the tap.
Only clean the tap with a soft cloth, warm water and a mild detergent solution, rinse the tap
clean thoroughly afterwards with water. Do not use any abrasive or harsh chemical products,
otherwise this will invalidate your guarantee.
These instructions are only intended as a guide, if there is any doubt then
