2 Installation
The fridge is designed to operate within a climate class 3 environment (25°C @ 60% relative
humidity), and should not be placed in a location that is likely to exceed these conditions.
Cabinet
Location Do not expose the cabinet to direct sunlight at any time, as this may cause plastic parts to
distort.
Do not place the cabinet in the direct airpath of air-conditioning outlets, ventilation fans or any
other fan which causes air movement directly into the cabinet opening. This will cause failure
of the air curtain and compromise the airflow and product temperature in the open cabinet
zone. Maximum air movement across the cabinet opening must not exceed 0.2 m/s.
Ventilation To prevent overheating and conserve energy, ensure there is always at least a 50 mm gap at
the back, 200 mm on the top and 60 mm at the sides of the cabinet. Keep the ventilation slots
in the lower front panel clear at all times. Never store cardboard cartons or other objects in front
of the fridge.
To maximise airflow at the rear of the cabinet, ensure both rear stand-offs are fully extended
outwards and locked into place. This will provide the necessary air gap at the rear of the
cabinet for correct operation.
Power Cord The fridge has a flexible power cord fitted with a 3-pin plug, at the rear of the cabinet. Take care
not to trap the cord or plug when positioning the cabinet.
Transportation The cabinet is not designed to be stable while in motion. Use extreme caution when moving
or transporting the cabinet if it has been removed from its original crate.
Never strap across the glass sides of the cabinet as this may cause damage.
Ensure appropriate padding or protection is used to prevent damage when strapping.
Shelves
Adjusting the
Shelves The fridge is fitted with five metal shelves. The four top shelves are height and angle
adjustable, and removable. The angled bottom shelf is angle adjustable. The top two shelves
are 1170W × 360D, the middle two shelves are 1170W × 380D, and the bottom shelf is
1179W × 400D.
IMPORTANT
The cabinet’s recommended operating temperature is between
18°C and 24°C and 60% relative humidity.
IMPORTANT
Do not leave the cabinet exposed to direct sunlight as this may
cause distortion of plastic parts.
IMPORTANT
There must be no air movement directly into the cabinet opening.
CAUTION
To prevent over-heating and conserve energy, ensure that air can
flow freely all around the cabinet, including underneath and on
top.

Installation
Service Manual
The four top shelves are held in place by two cantilevered shelf brackets which clip into cut-
outs in the cabinet back duct. The top four shelves can be adjusted at 28 mm increments (see
image below).
Procedure 1: To reposition a shelf
1. Disconnect the cabinet from the power supply (see page 18).
2. Remove product from the shelf that is being moved.
3. If present, lift the gravity feed matting from the shelf and remove from the cabinet.
4. Unplug the shelf light cable at the inside of the
right hand shelf bracket.
5. Lift the shelf up off the brackets and remove from the cabinet. Be careful not to damage the shelf
light cable.
6. Unwind the cable from the back of the shelf bracket.
7. Select the new position and move the shelf brackets. The shelves can be repositioned as far as
the shelf light cable reasonably allows.
8. Place the shelf, and if present the gravity feed matting, onto the shelf brackets. Ensure the back
of the shelf clips over the rear of the brackets.
9. Push the cantilevered brackets outwards until
they clip into the edge locating slots on the
side of the shelf.
10. Take up any excess shelf light cable by winding it through the two holes at the rear of the shelf
bracket, and reconnect the shelf light cable plug. Make sure that the plug is securely attached to
the correct socket.
11. Reconnect the cabinet to the power supply, and check for correct operation.

Gravity Shelf
System Gravity feed matting, including shelf dividers, is available for each shelf. The gravity shelf
system comes in two sizes to suit the different size shelves: 350 mm depth for the top four
shelves, and 385 mm for the bottom shelf. Each has 16 dividers.
Procedure 2: To fit the gravity feed matting and shelf dividers
1. Match up the shelf dividers with the corresponding matting.
2. Work across the matting and fit the centre dividers at required intervals.
3. Place the mat and dividers onto the matching shelf inside the cabinet.
4. Repeat for the remaining shelves.
5. To adjust the spacing between dividers:
•Push the divider towards the rear of the cabinet until it unclips from the matting.
•Move the divider to the required spacing, and insert into the slot in the matting kit.
•Pull the matting towards the front of the cabinet to lock it in place.

Faults and Alarms
If a fault occurs, it is logged, the Fault - Alarm indicator is lit on the controller faceplate, and a
message may be displayed. Faults do not affect product temperature, and do not require
action from the shop owner, unless they turn into an alarm.
If an alarm occurs, it is logged, the Fault - Alarm indicator is lit, and the alarm message is
displayed on the controller faceplate. Alarms may result in abnormal product temperature.
Some faults and alarms can be cleared by the shop owner, and others can only be cleared by
a service technician. Faults and alarms can be cleared by the shop owner by power-cycling
the cabinet. However the fault or alarm will only clear if the problem has been fixed. If the
problem still exists after a power-cycle, a service technician will need to fix the problem.
Load parameter file
Allows you to reload a default parameter set or
change to new parameter set.
SKOPE does not recommended changing
