Maintenance

General

Read the section 'Important Safety Information' first.
If any maintenance is required then it must be carried out by a competent tradeperson
for whom the maintenance instructions are provided. Before replacing any parts make
sure that the underlying cause of the malfunction has been resolved.
► Warning! There are no user serviceable components beneath the cover of
the appliance. Only a competent tradesperson should remove the cover.

Cleaning

Many household cleaners contain abrasives and chemical substances, and should
not be used for cleaning plated or plastic fittings. These finishes should be cleaned
with a mild washing up detergent or soap solution, and then wiped dry using a soft
cloth.

Checkvalve Cartridges - Removal and Installation

Hot water entering the cold supply, or vice versa, indicates that immediate attention is
necessary. This is carried out by removing and cleaning, or renewing as necessary,
the checkvalve cartridges.
► Isolate the water supply to the Digital Mixer, and open an outlet fitting to release
pressure and to assist the draining of residual water.
► Isolate the electrical supply.
► The checkvalve cartridge assembly may be removed for cleaning. Inlet
strainers can be flushed through under a jet of water to remove any lodged
particles.
► Note! Some valves do not have checkvalve cartridge assemblies fitted, only
checkvalve and strainers fitted.
