OPERATING INSTRUCTIONS
Multi Deck Display Cabinets
R - Series
M - Series
Please read the Operating Instructions before using the cabinet.
The Williams GEM range temperature parameters are set as follows:
+3°C (37°F) / +5°C (41°F)
OLD CABINETS
Please ensure the old / redundant cabinet and refrigeration equipment are disposed of safely and legally.
We would recommend that any internal fittings/doors are removed prior to disposal to ensure safety.
UNPACKING
Ensure that the cabinet has arrived in good order and that no damage during transport has ocurred.
Remove all external and interior packing and accessories, please ensure all packaging is disposed of
safely.
MAINS CONNECTION
The cabinet comes fitted with moulded plug for safety and must be earthed. We recommend that should
the plug or cable fail contact Williams Refrigeration for a replacement part, (contact details can be found at
the back of this booklet).
INSTALLATION
The Multi Deck Display cabinet should be installed in a dry place, avoiding direct exposure to sunlight and
sources of heat or draughts including air currents such as radiators, fans, air conditioning units and doors
etc. Ensure there is a gap at the back of the cabinet if positioned against a wall of at least 60mm to ensure
the condensing unit operates effectively and efficiently. The cabinet is fitted with castors as standard, please
ensure the cabinet is level and in a stable position for safe and efficient usage.
If the cabinet has been laid on its back or tipped, DO NOT switch on immediately. Leave the cabinet in the
upright position for at least1 hour before switching on.
The minimum ambient required is 16°C with a maximum of 25°C and a relative humidity of 60°C.
To ensure optimum operation of the refrigeration system, DO NOT block the front of the cabinet and air flow
vents.
Locking Castors
When the cabinet has been positioned please ensure brakes have been activated by pressing the metal bar
down. Remember to release the brakes before trying to move the cabinet.
Shelf/Slide Fitting
To adjust the position of the trayslides insert the ends into the vertical support with the ‘hooks’ pointing downwards and slot downwards into position. Ensure trayslides are parallel and level after fitting.
Shelf Weight Distribution
When loading the cabinet please ensure the load is equally distributed throughout the cabinet and ensure
air can circulate around and through stored products.
VENTILATION
It is essential to ensure that the room in which the equipment is installed is adequately ventilated. Multi Decks
can generate considerable amounts of heat and if operated in small unventilated rooms, especially in warm
weather, will quickly cause the room temperature to rise to excessive temperatures which can cause motor
overheating and possible damage to the windings. Ensure there is a gap at the back of the cabinet if
positioned against a wall of at least 60mm for the condensing unit to operate effectively and efficiently.
LOCKING FACILITY
On models fitted with a security shutter which has a locking facility it is recommended that the key be
removed from the lock during normal working use. If the key is left in the lock it can be knocked
causing it to bend or break in the barrel, making the lock inoperative.
THERMOMETER
The controller is marked in Centigrade for the thermometer display. The thermometer should be checked
daily to ensure that the equipment is maintaining the correct temperature.
CONTROL PANEL
Set-up Procedure
The controller is factory set therefore you should not have to enter the set-up procedure. A qualified
refrigeration engineer should be called if any parameters need changing.
SET: To display target set point; in programming mode it selects a parameter or confirm an operation.
(DEF): To start a manual defrost.
(UP): To see the maximum stored temperature; in programming mode it browses the parameter
codes or increases the displayed value.
(DOWN): To see the minimum stored temperature; in programming mode it browses the
parameter codes or decreases the diaplsyed value.
Meaning of LED’s
Each LED function is described in the following table.
LED MODE FUNCTION
ON Compressor enabled
Flashing - Programming Phase
- Anti-short cycle delay enabled
ON Defrost enabled
Flashing - Programming Phase
- Drip time in progress
INITIAL OPERATION
Your cabinet is delivered ready to operate. Check that the cabinet is connected to the correct electricity
source (230V - 50Hz). Plug into the mains and the cabinet is ready for use. Wait until the cabinet has
reached its normal operating temperature (shown on the control panel) before loading it.
Ensure all shelves are fitted so they are in contact with back panel. To ensure effective air circulation leave
a gap of 60mm between products and the shelf above. The products should be evenly distributed on the
shelf. (See Fig.1)
We recommend the night blind or security shutter be used overnight or when the Multi Deck is not in use to
save on electricity.
Fig.1
ADJUSTING THE OPERATING TEMPERATURE
To access the parameters, enter the programming mode by pressing the SET and UP key for 3 seconds
(? and ? start blinking), then select the required parameter in the following sequence:
- Press the “SET” key to display its value (? LED starts blinking).
- Use “UP” or “DOWN” to change its value.
- Press “SET” to store the new value and move to the next parameter.
To exit: Press SET and UP or wait 15 seconds without pressing a key.
NB: The set value is stored even when the procedure is exited by waiting for the time-out to expire.To adjust
the operating temperatures, press and hold the SET key for more than 3 seconds, while the maximum or minimum temperature is displayed. (rSt message will be displayed). To confirm the operation the
“rSt” message starts blinking and the normal temperature will be displayed.
NB: All machines are preset at the factory, however conditions on site will vary compared with test
conditions and it may be necessary to perform the above adjustments several times in order to
obtain a perfect temperature cycle. We would recommend this is done by a qualified refrigeration
engineer.
DEFROST OPERATION
Push the DEF key for more than 2 seconds and a manual defrost will start.
IdF Interval between defrost cycles: (1/120h)
Determines the time interval between the beginning of two defrost cycles.
MdF Length for defrost: (0/255mins)
It sets the defrost duration.

2. Air circulation restricted Remove Restriction
3. Check that shelves and goods are properly installed and loaded
4. Check that the cabinet is not near draughts or heat sources
5. Check that the air return of the air curtain is not blocked
BREAKDOWN
In the event of a breakdown, please check the thermostat setting and fuse before calling the service
engineer. When calling the engineer, please advise him of the model and serial number of the machine.
These details are on the identification plate on the back of the cabinet and should also be noted on the back
cover of this booklet. Please ensure any redundant parts are disposed of safely and legally.
CLEANING
Normal day to day cleaning of the exterior and interior of the cabinet should be carried out with lukewarm
soapy water and a soft cloth. Never use abrasive materials or cleaners, or chemical cleaners. Do not wash
the cabinet with a hose or spray. (Fig.2)
ROUTINE MAINTENANCE
All maintenance should be carried out by a competent, qualified person. We recommend that you
undertake regular preventative maintenance using a qualified service provider in order to get the best from
your equipment.
CONDENSER CLEANING
The condenser, which is part of the refrigeration unit, is sited in the unit compartment and requires cleaning,
approximately 4 times per year.
Disconnect the cabinet from the electrical supply by
unplugging it then, to achieve access to the condenser
you must remove the screws followed by the front panel.
(Fig. 3)
To clean the condenser, disconnect mains supply before
starting, then brush the fins vertically with a stiff brush, taking
care not to damage the fins or push dirt or dust further in and
vacuum away. Remember to reconnect mains supply once
finished.
