Routine Maintenance - Williams MHC10 Operating Manual

APPLIANCE ROUTINE MAINTENANCE / CLEANING

ROUTINE MAINTENANCE

Safely disconnect the appliance from the
power supply before cleaning, servicing or
undertaking general maintenance.
This appliance must be maintained at regular
intervals. The frequency of maintenance will depend
upon your specific use and location. The maximum
service interval should be 12 months.
Service and maintenance should only be undertaken
by suitably qualified, trained and competent
engineers.
CLEANING
Always wear appropriate personal protective
equipment (PPE) when cleaning the appliance. Care
should be taken for parts with possible sharp edges.
Stainless steel is naturally corrosion-proof and
needs no additional protective coating to maintain
its gloss and usability for a long time.
Abrasive or corrosive cleaning agents should never
be used. These can damage surfaces and cause
corrosion. They include:
• Cleaners containing chloride;
• Bleaches containing hypochlorite (if accidentally
spilled on stainless steel, rinse off with water
immediately and thoroughly);
• Silver polish
If the cabinet exterior is looked after correctly it will
retain an "as new" finish for many years. A damp
cloth is usually sufficient for wiping away light dirt,
food debris and finger marks and normal day to day
cleaning should be carried out with a soft cloth and
soapy water.
Dry thoroughly afterwards and where possible
remove all racking, shelving and drawer fittings to
aid the process.
Kitchen fats, oils and greases can also cause brown
spots or staining to appear on the stainless steel
surface.
For stainless steel with visible polishing grains, clean
the steel with the grain - not against the grain. When
water has been used for cleaning or rinsing, wipe
the surface dry to prevent water from drying and
forming watermarks, especially in areas with hard
water. Avoid this type of watermark by using distilled
water.
APPLIANCE ROUTINE MAINTENANCE / CLEANING
For tougher spots, creamy polishes like CIF original
cream can be effective. Light pressure should be
used when cleaning with the grain. The cleaning
process should be repeated in order to prevent any
dirt becoming lodged in the surface grain again.
CIF original cream cleaner can also be used
for wiping off water spots and can alleviate
discoloration. Remove this type of residue by rinsing
with clean, preferably distilled water and wipe away
any remaining streaks of polish or watermarks.
Tough grease or oil marks can also be removed
using denatured alcohol or acetone. There is no risk
of corroding stainless steel by using such solvents.
For ease of use limit the amount of solvent used.
Wash more than once using a pure solvent on a
clean soft rag until all traces of the greasy residue
are removed.
Specialist Stainless Steel Cleaners - Non food
contact surfaces only
Innosoft B570 is a special deep cleaner that is
suitable for the intensive cleaning of contaminated
stainless steel surfaces, and removes stains and
oxides in a single operation.
Innoclean B580 completely removes any residues
left after the use of Innosoft B570 and passivates
the surface which helps to prevent further
corrosion.
SHELF / SUPPORT/ RACKING REMOVAL
First remove the shelves, then remove the shelf
supports by grasping firmly in the centre and lifting
slightly. Turn the shelf support towards the interior
of the cabinet by pushing it in the centre as you
twist the support through 90°. The shelf support
will be released. (NB: the supports are designed
to be anti-tilt and you may therefore experience
some resistance at first which will be overcome with
practice). When all shelves have been removed,
remove the racking by lifting up and over the nylon
retaining blocks.
