Maintenance Procedures
Maintenance must be carried out in accordance with these instructions, and must be
conducted by designated, qualified and competent personnel.
This mixing valve series is designed for minimal maintenance under conditions of normal use.
External surfaces may be wiped clean with a soft cloth, and if necessary, a mild washing-up
type detergent or soap solution can be used.
Warning!
Many household and industrial cleaning products contain mild abrasives and
chemical concentrates, and should not be used on polished, chromed or plastic surfaces.
Should an internal malfunction occur then this will probably require cartridge renewal. The
cartridge assembly and check valves contain no user-serviceable parts, and must not be
dismantled.
Components are precision-made, so care must be taken while servicing to avoid damage.
When ordering spare parts, please state product type, i.e. Rada 320 IC, and identify part
name and number (refer to PARTS LIST ). A Seal pack is available, containing all the seals
that may be necessary for renewal during maintenance or servicing.
