INSTALLATION
REMOVAL OF REDUNDANT APPLIANCES
Refrigeration appliances contain refrigerant and
gases in their insulation and must be disposed of
professionally by a licensed waste management
contractor.
Please ensure that old or redundant refrigeration
appliances are disposed of safely and legally. It is
recommended that doors are removed prior to
disposal in order to ensure safety.
UNPACKING
Remove all external and interior packing and
accessories. Ensure all such material is disposed
of safely.
Check that no damage has occurred to the
appliance, the tubing of the refrigeration system
power cable and plug top during transit. If damage
has occurred do not use the appliance.
The appliance should be installed in a well ventilated
room on a at and level oor.
PROTECTIVE COATING
The polished stainless steel surfaces are protected
during manufacturing and transport by an adhesive
plastic coating.
This should be removed prior to placing your
appliance into use. Carefully peel away to reveal
the polished stainless steel surface. Care should be
taken to ensure that no adhesive residue remains
on the surface. Any stubborn or tough adhesive
marks can be removed by following the advice on
Page 9.
VENTILATION
Refrigerators generate a considerable amount of
heat and, if operated in a small unventilated room
will quickly cause the room temperature to become
excessive. This could cause the motor to overheat
and possibly damage the compressor. At the very
least, such an installation will cause the unit to use
an excessive amount of electricity.
In addition to ventilation in a room, please ensure
that cabinets with top-mounted systems have
500mm clearance between the cabinet top and the
ceiling for engineer access and ventilation. For all
other cabinets, please ensure a minimum clearance
of 50mm is provided around the unit to ensure
ecient and eective performance.
LEVELLING (CASTORS/FEET)
The appliance should stand level to ensure the
correct operation of self-closing doors and proper
drainage of condensate from the evaporator.
Models tted with castors are non-adjustable.
Therefore a level platform / oor should be
provided where the appliance is to be located.
Where swivel and brake castors are tted and it
has been positioned, please ensure its brakes have
been activated by pressing the metal bar down.
Remember to release the brakes before trying to
move it.
On models tted with legs, levelling may be achieved
by adjusting the bottom section. For marine
specication models with anged feet for deck and
bulkhead xing, installation should be carried out by
a specialist marine company.
AIR GAP BRACKETS FOR AN ONYX
The Onyx range, is supplied with 2 x stand-o
brackets (see Figure 1). These are supplied loose
/ packed inside the cabinet for ease of installation
/ access, but must be tted before cabinet is
pushed into place to provide the necessary air gap /
condensing unit air circulation.
These can be simply attached to the rear of the
cabinet using the two screws already tted. Hook
the bracket key hole slot over the screw heads and
push down. Once in place, tighten the screws.
Please note that failure to t these will aect
the performance of the cabinet and will
invalidate the warranty.
Do not block vents by stacking boxes on top
or in front of the unit as this could aect
performance and give rise to safety risk.

WALL BRACKETS FOR A THERMOWELL
(OPTIONAL EXTRA)
If the Thermowell is supplied with wall brackets,
please proceed as follows;
Secure the brackets to the wall using M6 xings and
position the Thermowell upon the brackets. Ensure
the feet are securely projecting through the large
holes in the brackets. (See diagrams below). The
Thermowell and brackets should be positioned as
indicated in Figure 2.
Fixing Points:
TW9 918mm apart - 2 points
TW15 724mm apart - 3 points
TW18 900mm apart - 3 points
NB: Each wall bracket will support 55kg.
DO NOT PLACE HEAVY OBJECTS UPON THE
THERMOWELL.
MAINS CONNECTION
Commercial kitchens and foodservice areas
are environments where electrical appliances
may be located close to liquids, or operate
in and around damp conditions or where
restricted movement for installation and
service is evident.
Great care must be exercised at all times when
installing, operating, or servicing this appliance.
For appliances tted with a moulded plug for safety,
ensure that the mains power cable is extended
free from the refrigeration system to avoid
entanglement. If a plug or mains cable requires
replacement, contact the Williams Spares Oce on
[phone].
The installation of a xed appliance and periodic
inspection should only be undertaken by a qualied,
skilled, and competent electrician; and connected
to the correct power supply suitable for the load as
stipulated by the appliance data label.
The electrical installation and connections should
meet the necessary requirements to the local
electrical wiring regulations and any electrical safety
guidelines.
All appliances rely upon a suitable connection to
earth to ensure safe operation. If in doubt, contact
a qualied, skilled, and competent electrician before
using the appliance.
We recommend:-
• Supplementary electrical protection with the
use of a residual current device (RCD)
• Fixed wiring appliances incorporate a locally
situated switch disconnector to connect to,
which is easily accessible for switching
o and safe isolation purposes. The switch
disconnector must meet the specication
requirements of IEC 60947
If the appliance has been laid on its back
or tipped, DO NOT switch on immediately.
Leave in an upright position for at least 3
hours before switching on.
Your attention is drawn to:-BS 7671:2018 -
Guidance note 8 - 8.13 : Other locations of
increased risk
It is recognised that there may be locations of
increased risk of electric shock other than those
specically addressed in Part 7 of BS 7671.
Examples of such locations could include laundries
where there are washing and drying machines
in close proximity and water is present, and
commercial kitchens with stainless steel units, where
once again, water is present.
Where because of the perception of additional risks
being likely, the installation designer decides that an
installation or location warrants further protective
measures, the options available include:
• Automatic Disconnection of Supply (ADS) by
means of a residual current device having
a residual operating current not exceeding
30mA;
• Supplementary protective equipotential
bonding; and
• Reduction of maximum fault clearance time.
The provision of RCDs and supplementary bonding
must be specied by the host organisation’s
appointed installation designer or electrical
contractor and installed by a suitably qualied
and competent electrician so as to comply with
Regulations 419.2 and 544.2.

clips (gure 4) for tting. Amber freezer models are
tted with xed shelves.
LOADING / SHELF DISTRIBUTION
Before loading, allow the appliance to reach its
normal operating temperature.
When loading the appliance, please ensure that its
load is equally distributed throughout and ensure air
can circulate around and through stored products.
Ensure all items are covered and that raw and
cooked foods are stored separately.
Care should be taken when loading the appliance.
Do not obstruct the air ducts. Take care of any parts
with possible sharp edges.
LOCKING FACILITY
On models with a locking facility, it is recommended
that the key be removed from its lock during normal
working use. This will prevent bending or breaking
of the key which could result in the lock having to be
replaced.
Removing the key will also prevent accidental
locking when the door is open. This will prevent the
door from closing properly and cause the interior
temperature to rise. If not checked in time, a loss of
food may result.

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 specic use and location. The maximum
service interval should be 12 months.
Service and maintenance should only be undertaken
by suitably qualied, 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 o with water
immediately and thoroughly);
• Silver polish
If the cabinet exterior is looked after correctly it will
retain an “as new” nish for many years. A damp
cloth is usually sucient for wiping away light dirt,
food debris and nger 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 ttings 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.
For tougher spots, creamy polishes like CIF original
cream can be eective. 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 o 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 rmly 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 rst which will be overcome with
practice). When all shelves have been removed,
remove the racking by lifting up and over the nylon
retaining blocks.
