INSTALLATION
REMOVAL OF REDUNDANT APPLIANCES
If the product needs to be disposed of, the relevant
legal regulations must be observed.
Within the European Community, the disposal of
electrical devices is regulated by national regulations
based on EU Directives pertaining to waste electrical
and electronic equipment (WEEE).
According to these regulations, any devices supplied
after August 13, 2005, in the business-to-business
sphere, to which this product is assigned, many no
longer be displosed of in municipal or domestic
waste. To document this, they have been marked
with the following marking:
Do not dispose of batteries together with domestic
waste. Dispose of batteries in accordance with local,
legal regulations.
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.
Because disposal regulations may dier from one
country to another within the EU, please contact
your supplier if necessary.
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 10.
INSTALLATION
During the initial start up, high temperature alarm
may sound while the appliance reaaches operating
temperatures. Allow the appliance to stabilise at the
set point before storing product.
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
ecient and eective 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 levelling feet, levelling may be
achieved by adjusting them rst.
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.
Do not block vents by stacking boxes on top
or in front of the unit as this could aect
performance and give rise to safety risk.
INSTALLATION

MAINS CONNECTION
Refrigeration equipment is commonly used in
environments located close to liquids, and is
usually operated in and around damp areas,
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.
The equipment is to be powered by a suitable
socket outlet which provides means of switching
o and/or disconnecting the power supply to the
equipment for cleaning or maintenance purposes. It
should be positioned in a clearly visible location, and
be easily accessible at all times. It is advised that
a label be xed adjacent to the designated socket
outlet for identication purposes, stating the outlet
is used to power the specic medical refrigeration
equipment.
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 Oce on
+44(0)1553 817017.
The installation of a xed appliance and periodic
inspection should only be undertaken by a qualied,
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 qualied, 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 switch
disconnector for purposes of safe isolation
to meet the specication requirements of IEC
60947
SUPERVISORY & NETWORK CONNECTIVITY
(OPTIONAL)
There is an option to connect the Medi+
refrigeration equipment to third party supervisory
networks and systems such as Building
Management Systems (BMS), and IoT cloud based
systems via an RS485 Modbus data connection. This
will allow for a comprehensive supervision of the
equipment operating parameters and status, such
as internal temperature, defrost cycles and alarms.
The Medi+ equipment controller also provides a volt
free contact, which can be connected to a BMS to
monitor general alarm conditions.
NB: A proprietary cable from Williams
Refrigeration is required and, only suitably
qualied and competent engineers should
install this equipment to such systems. For
more information, please contact Williams
Refrigeration on +44(0)1553 817000.
MAINS POWER SUPPLY FAILURE ALARM
(OPTIONAL)
This alarm is to help safeguard stored medical
samples/items by announcing when a failure of the
mains power supply has occurred. An audible (95dB
sounder), and a visual alarm (red ashing ‘Power
failure’ indicator) will activate in the advent of a
mains power supply failure.
The alarm will be continuous for a minimum of
12 hours, (whilst the mains power supply failure
remains), powered by a rechargeable battery
integrated into the alarm circuit; however, the
sounder can be muted at any time by pressing the
‘Mute’ button. Once muted, a blue ashing indicator
signies that the alarm has been muted. The red
ashing ‘Power failure’ indicator will continue to be
active whilst there is a failure of the mains power
supply.
When the mains power supply is reinstated the
‘Alarm muted’ function MUST be reset by pressing
the mute button once more, cancelling the blue
ashing indicator signifying that the alarm circuit is
ready to sense a power failure.
IMPORTANT: for the rechargeable battery
to receive a full charge, it is advised that
the mains power supply is connected for
at least 24 hours. As with all batteries, the
rechargeable battery has a nite operational
life which will vary dependent of a number of
factors, it is therefore, advised that the mains
power supply failure alarm is checked by a
service engineer as part of the routine periodic
servicing of the refrigerator. Only replace the
battery with a Williams Refrigeration approved
and supplied battery.

SHELF/SLIDE FITTING
When positioning slides on standard cabinets and
counters, present slide to racking by holding it in
the opposite hand to the side of the cabinet to that
which they are to be applied. Present slide at 45°
angle (gure 1). When in place, let slide drop into
position to create a horizontal ledge on which the
shelves will sit.
The WMP135 models are tted with pilaster and
clips (gure 2) for tting.
LOADING / SHELF DISTRIBUTION
Before loading, allow the appliance to reach its
normal operating temperature.
• Never load beyond capacity.
• Always store items within shelves.
• Uniform product temperature is maintained by
air circulation, ensure even loading.
• Do not place items against the rear plenum or
pushed against side walls.
When loading the appliance, please ensure that its
load is equally distributed throughout and ensure air
can circulate around and through stored products.
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
product may result.

APPLIANCE ROUTINE MAINTENANCE / CLEANING
APPLIANCE ROUTINE MAINTENANCE / CLEANING
ROUTINE MAINTENANCE
Safely disconnect the appliance from the
power supply before cleaning, servicing or
undertaking general maintenance.
We recommend that you undertake regular
preventative maintenance using a qualied
service provider in order to get the best from
your equipment.
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 sucient for wiping away light dirt
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 and shelving ttings to aid the
process.
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 eective. 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
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.
With regards to the above recommended cleaners,
always check that they will not have any detrimental
eect to the stored contents.
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.
11
APPLIANCE ROUTINE MAINTENANCE / CLEANING
CONDENSER CLEANING
Regular maintenance should be carried out on a
regular basis by competent / trained personnel. The
condenser is part of the refrigeration unit and is
located in the unit compartment.
Brush ns vertically with a sti brush, taking care
not to damage them or to push dirt / dust further in,
and then vacuum away.
TOP MOUNTED CABINETS
(WMP620 - WMP1295)
The condensing unit and refrigeration equipment
can be accessed from above or in some cases
behind. Remove xings in the top and bottom edges
of the unit cover and pull the unit cover away from
the cabinet and retaining clips.
BOTTOM MOUNTED UNITS
(WMP523)
Pull the unit cover away from the cabinet and
retaining clips.
CLEANING / REPLACING THE GASKET
Door gaskets should be checked and cleaned
regularly and replaced if damaged. To clean the
gasket, wipe with warm soapy water and a soft cloth,
ensuring it is completely dry before closing the door.
DO NOT use a sharp knife to clean or scrape the
gasket. Damaged gaskets do not seal correctly and
can increase the amount of electricity consumed,
seriously aecting the eciency and performance of
the appliance.
Damaged gaskets are easily
replaced. Simply pull out the
existing part and push the new
gasket into the channel (gasket
retainer) at the centre and work
along, pushing gasket into
channel.
EVAPORATOR/DRAINLINE
Inspect periodically to ensure the drain hole is not
blocked.
BREAKDOWN
In the event of a breakdown, please contact Williams
Refrigeration or your Service Provider
When calling, please advise model and serial
number. This information can be found on the data
plate inside the appliance. Please ensure that all
redundant parts are disposed of safely and legally.
