5If problem persists contact our helpline quoting the product code
Where an aerator is fitted to the outlet of the spout, it will need occasional cleaning.
This will be evident when the water flow slows down to an unacceptable level. To accomplish
this unscrew the outlet in an anti-clockwise direction and remove the mesh. Immerse the mesh
in a suitable descaling fluid overnight, rinse throughly in clean water and re-install.
Maximum water supply pressure 5 bar (75PSI) Minimum water supply pressure 0.5 bar
Maximum hot water supply temperature 70˚C
Recommended hot water supply temperature 65˚C
If these temperatures or water pressure are exceeded, damage to the tap can result. A pressure
reducing valve may be required to be fitted in high water pressure situations.
PREPARATION
INSTALLATION
It is very important that you read through the following instructions
BEFORE you install and use the tap.
Screw the flexible hoses (hot flexible hose on the front) into the mixer body, and fully
hand tighten.
Pass the flexible hoses and threaded stud through the sink top from above and place the
mixer in position on the sink.
Slide the flat washer and fixing nut up the flexible hoses, and then screw the nut all the way
up making sure the tap is in the correct position.
Connect the check valve group to the cold water inlet pipe first, and then to the cold end
Flexible hose.
Having first checked all the new connections, turn on the mains stop cock, close all taps
except the new mixer and as the system starts to refill check for leaks.
Make sure that sealing washer has been fitted to the mixer body.
(Note:The thickness of sink>35mm no need to use the mounting seat.)
We strongly recommend installing particle filters and isolation valves to both hot and cold feeds.
This will help to prevent premature failure of valves and make any future maintenence easier.
Flush the plumbing system before installing the mixer tap. This is to void plumbing residues
clogging the mesh of the aerated outlet, or possibly damaging the valve’s washers. This is
especially important where extensive plumbing work has been carried out.
First shut off your water heating system then, with your mains stop cock closed, open the lowest
hot and cold taps in the house and allow to run until the cold storage tank and pipes are empty.
(The hot water storage cylinder always remains full).
