CLEANING & SERVICING
Cleaning chrome
• Do not use abrasive, chlorine or any other acid-based cleaning products. Clean with hot,
soapy water and a clean cloth or sponge. Dry using a clean, dry cloth.
Frost protection
• Drain the pipes and operate the mixer several times to drain any remaining water.
REMEMBER
• Our mixers/taps and valves must be installed by professional installers in accordance
with current regulations and recommendations in your country, and the specifications of the
fluid engineer.
• Sizing the pipes correctly will avoid problems of water hammer and loss of pressure/flow
rate. (See the calculation table in the brochure or on line at www.delabie.com).
• Protect the installation with filters, water-hammer absorbers or pressure reducers to reduce
the frequency of maintenance. (Recommended dynamic pressure: 1-5 bar, 2 bar for siphon-
action urinals) to facilitate maintenance.
• Install stopcocks close to the mixer to facilitate maintenance.
• The pipework, stopcocks, valves and all sanitary ware must be checked regularly.
