InstallationProcedure
Lefroy Brooks always recommends that plumbing products be installed by a licensed professional.
Shut off main water supply before installation.
1Before installing the valve into the wall, please note that a distance between 80mm~105mm
from the wall surface to the rear of the valve should be left so that the trim can be fitted
correctly.
2Install valve assembly into the wall.
3Cut a hole on the wall surface for fitting the trim kit. The hole dimension is as shown in figure 3.
4Throw away the protective caps only when building construction is completed and you are ready
to fit the trim kit in.

SafetyTips,CareandMaintenance
Safety Tips
If you are soldering during faucet installation,remove cartridges, seats, gaskets and washers prior to
applying flame, otherwise you will void the warranty.
Cover drain openings to avoid losing small parts.
When cutting or soldering pipe, use safety glasses to protect your eyes.
Important Points
Prior to beginning installation. turn off the cold and hot water lines and open the old faucet to release
built-up pressure.
Overtightening nuts may cause damage.
Wrap all threaded connections with pipe tape available at your local plumbing supply store.
Always wrap in a clockwise direction. The fittings should be installed by a state-licenced plumber.
Please note:
When there is a difference in water pressure between hot and cold supplies to the mixing valve, the
pressures should be equalized by a plumber in accordance with best practice and legislation.
Maintenance
Your new bathroom faucet is designed for years of trouble-free performance. Keep it looking new by
cleaning it periodically with a soft cloth. Avoid abrasive cleaners, wire wool and harsh chemicals as
these will dull the finish and void your warranty.
Routine Maintenance
The frequency and extent of attention required will vary according to prevailing site and operational
conditions, however a 12 monthly maintenance schedule is recommended.
If the product has operated satisfactorily for some time, but performance has been degraded, please
check the Fault Finder section to identify the problem.
