INSTALLATION

Removal of Redundant Cabinets

Please ensure that old or redundant refrigeration
cabinets and equipment 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,
power cable and plug top during transit. If damage has
occurred do not use the appliance.
We recommend that prior to use, the appliance is
cleaned with a mild soap solution and then wiped dry.

Ventilation

It is essential to ensure that the room in which the
unit is to be installed has adequate ventilation.
Refrigerators generate a considerable amount of heat
and, if operated in a small unventilated room in warm
weather, these will quickly cause the room temperature to
become excessive. This could cause the motor to
overheat and possibly damage the windings. At the very
least, such an installation will cause the unit to use an
excessive amount of electricity. A single door unit usually
generates 1200W of heat, a two door version - 1800W
and a three door model 2400W whilst running (these
figures are approximate).
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 adequate clearance of 50mm
is provided around the unit to ensure efficient and
effective performance. Do not block vents by stacking
boxes on top or in front of unit as this could affect
performance.

Wall Brackets for a Thermowell (Optional Extra)

If Thermowell is supplied with wall brackets, please
proceed as follows:
Secure brackets to wall using M6 fixings and position
Thermowell upon 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 3.

Fixing Points:
TW9 918mm apart - 2 points
TW15 724mm apart - 3 points
TW18 900mm apart - 3 points

Fig. 3

NB: Each wall bracket will support 55kg. DO NOT
PLACE HEAVY OBJECTS UPON THERMOWELL.

Instructions on how to fix stabilising brackets to all
Sapphire 1 & 2 door cabinets with glass doors

1) Use three 8 x 1/2” pozi fixings to secure Plate B to
Plate A via three slots. Plate B is adjustable vertically
when it has been secured to the floor.

2) Three holes are provided in Plate B so it may be
secured to floor. Drill and secure using sufficient
fixings and plugs (not supplied).

3) When plate B has been secured to floor the fixings can
be tightened and the additional holes can be drilled
and secured to plate A.

To fix bracket on cabinet LH side, repeat steps 1, 2 & 3.

Levelling/Castors/Feet

The cabinet should stand level to ensure correct
operation of self-closing doors and proper drainage of
condensate from the evaporator.
Models fitted with castors are non-adjustable, therefore a
level platform/floor should be provided where cabinet is
to be located. Where swivel and brake castors are
fitted and when cabinet/counter has been positioned,
please ensure brakes have been activated by pressing
metal bar down. Remember to release brakes before
trying to move cabinet/counter. On models fitted with
legs, levelling may be achieved by adjusting the bottom
section. For marine specification models with flanged feet
for deck and bulkhead fixing, installation should be
carried out by a specialist marine company.

Mains Connection

The cabinet comes fitted with a moulded plug for safety
and must be earthed. Ensure that the mains power cable
is extended free from the refrigeration system equipment
to avoid entanglement. We recommend supplementary
electrical protection with the use of a residual current
device (RCD). Periodic testing, repair and fixed wiring
connections should only be undertaken by a skilled and
competent electrician.

If plug or cable should fail, please contact the spares
office on [phone] for a replacement.

If the cabinet has been laid on its back or tipped,
DO NOT switch on immediately. Leave in an upright
position for at least 1 hour before switching on.

The equipment must be connected to the correct mains
power supply as stipulated by the appliance data label
and local authority regulations.

Connection to Main Drains

Please note: if installing a fish cabinet, please ensure that
it is connected to a main drain.

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 a 45° angle (see
Figure 5). When in place, let slide drop into position to
create a horizontal ledge on which the shelves will sit.

OVERNIGHT OPERATION
Thermowells/Salad Counters/
Raised Panholder Options/Wells Options/Onyx

We recommend that users remove all food products and
place in suitable refrigerated storage overnight.

THERMOMETER

The controller is marked in Centigrade or Fahrenheit.
The Thermometer should be checked daily to ensure that
correct temperature is being maintained.

Shelf Weight Distribution
Before loading, allow cabinet to reach normal
operating temperature.

When loading cabinet/counter, please ensure that 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.

Locking Facility

On models with a locking facility, it is recommended that
the key be removed from 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 any possibility of
accidental locking when the door is open. This will
prevent the door from closing properly and will cause the
interior temperature to rise. If not checked in time, loss of
food may result.

Adjusting the Operating Temperature

The thermostat is built into controller and is adjustable
between factory set parameters.

Press and hold Use keys to adjust.

Then release .

If no further adjustments are made within 10 seconds,
the desired operating temperature will be stored and
display will revert to actual cabinet operating
temperature.

NB: All machines are preset at 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.

Door Alarm

The controller features a built in audio/visual Door open
alarm. If the door has been left open for 5 minutes or
longer then the cabinet will emit an audible alarm and AL
will flash in the display window. Press any button to
acknowledge the alarm, the alarm will mute and do will
appear in the window. Shut door and alarm will cease,
however the visual alarm continues if the door switch has
a malfunction or if there is another fault, the window will
show a different display - call a Service Engineer.

Hi-Lo Alarm

The controller features a built in audio/visual Hi-Lo alarm.
If temperature within appliance exceeds the factory set
alarm temperatures for 60 minutes or more, the controller
will emit an audible alarm signal and hi or Lo will flash
until the temperature returns to normal operation.

Probe Fail Safe Feature

The controller features a fail-safe condition. In event of a
temperature probe failure, the compressor will alternate
at 5 minute intervals indefinitely between running and not
running condition and E1 or E2 will be displayed.
Normal compressor function will only be restored when
probe fault has been repaired.

Defrost Operation

When defrosting is in progress, defrost indicator on
control panel (refer to control panel diagrams) will
become illuminated and dF will appear in LED display.
Defrost is automatic and cabinet will go through an
automatic defrost cycle at preset intervals. The defrost
operation does raise cabinet temperature slightly for a
short period but does not affect product stored inside.

Off Cycle defrost is carried out on the following cabinets:

General produce (H), Fish (F) and Wine (W).

Electric defrost is carried out on these cabinets:
Fresh Meat (M), Freezer (L) and Chilled Food (CF).

The audible alarm may be cancelled by pressing any
button. The alarm will go off again after 60 minutes if fault
has not been addressed. However, hi or Lo will continue
to show in LED Display until cabinet returns to
temperature or fault is corrected.

Condenser Cleaning Light (Integral cabinets/
counters only)

The LED next to condenser cleaning button (refer to
control panel diagrams) will flash to indicate condenser
requires cleaning - there is NO AUDIBLE ALARM. This
has been factory preset for maximum efficiency.

To cancel flashing LED, push and hold condenser
cleaning button for 3-5 seconds.

Cancel/Reset Condenser Clean:

Press and hold for 5 seconds to cancel flashing
LED.
