Safety Tips, Care and Maintenance
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.
