1.1 Safety Information
When using any electrical appliance, safety precautions should
always be observed. Read theseinstructions carefully andretain for
future reference.
• When used by, or near, young children or infirm persons, close
supervision is necessary. Young children should be supervised
to ensure that they do not play with the appliance.
• Do NOT use this appliance for other than its intended use.
• Do NOT cover the grilles or block the entry or exhaust of airflow
by placing objects up against the refrigeration unit.
• Do NOT probe any opening.
• Only use this appliance with voltage specified on the rating label.
• Ensure adequate ventilation of the SKOPE refrigeration unit.
• Be careful not to touch moving parts and hot surfaces.
• Regulations require that all electrical work be carried out by
authorised persons. For your own safety, and that of others,
ensure this is done.
• If the supply cord becomes damaged, it must be replaced by a
SKOPE authorised service agent, or similarly qualified person,
in order to avoid a hazard.
• If the refrigeration unit is required to be installed or removed
from the cabinet, ensure all necessary safety precautions are
observed.
Warning: Do NOT overload the power supply.
Caution:
Disconnect the cabinet from the mains power supply before
attempting any cleaning or maintenance.

3. 2 Cleaning
When necessary, wipe both the interior and exterior of the cabinet
with a damp cloth. Ensure the cabinet is disconnected from the
mains power supply before cleaning the cabinet. Periodic cleaning
of the condenser coil is also recommended.
Condenser coil
The condenser coil MUST be kept clean for efficient and reliable
operation. To ensure trouble free performance, the condenser coil
should be brushed clean oncea monthandblownclean by qualified
service personnel every six months. The condenser coil is situated
behind the sign unit (see Figure 7). To access the condenser coil:
1. Disconnect the cabinet from the mains power supply.
2. Loosen the sign retaining clip on the top of each side panel and
lift the sign unit up, to disengage from the sign sides.
3. Disconnect the sign plug from the electrical box socket and
remove the sign unit from the cabinet.
4. The condenser coil is now accessible for cleaning.

1.2 Positioning the Cabinet
Installation Guidelines
When positioning the cabinet, adequate clearance must be
maintained for ventilation. For efficient operation of the chiller, it is
essential that adequate ventilation be provided above the
refrigeration unit.
The maximum recommended ambient temperature for the chiller is
32°C.
When installing the cabinet:
• Avoid direct sunlight and warm draughts etc.
• Allow adequate space for the door/s to open fully.
• Ensure the cabinet is positioned on a level surface so the door/s
shut and seal correctly, and to prevent the condensate tray from
overflowing.
• The self-closing door/s have internal torsion bars, pretensioned
at the factory, and should not require any further adjustment.
• A gap must be left between the top of the sign panels and ceiling
of at least 200mm. The cabinet is designed so that it can be
installed against a flat surface such as a wall.
• The mains flex, which exits below the sign rear panel behind the
refrigeration unit, should be retrieved before the cabinet is
positioned.
• Do not overload the power supply. Model SC-650 is rated at
3.45A. Model SC-970 is rated at 4.46A.
Important:
For efficient operation of the cooler, it is essential that
adequate ventilation be provided above the refrigeration unit.

Sign Light
The SC-970 sign unit is fitted with a 21 Watt T5 fluorescent tube
(Ø16mm x 850mm). The SC-650 sign unit is fitted with a 14 Watt
T5 fluorescent tube (Ø16mm x 550mm).To replace the fluorescent
tube:
1. Disconnect the cabinet from the mains power supply.
2. Start at one of the top corners of the sign unit and pull the
curved sign panel out from under the sign top (see Figure 5
below).
3. Work alongthe length of the sign unit, pulling the signpanel out
as you go.
4. Carefully remove the sign panel away from the sign unit.
5. The fluorescent tube can now be removed. Revolve the tube
until the pin position allows withdrawal (see Figure 6 below).
6. When refitting the sign panel, ensure both sign panel end strips
fit neatly into the top and bottom corner notches.

1.3 Fitting the Sign Unit
For transit purposes the sign unit and sign side panels are packed
inside the cabinet. To fit the sign unit assembly to the top of the
cabinet:
1. Fit both the sign side panels over the four retaining screws on
top of the cabinet. Slide the panels forward, flush with edges of
the cabinet, and tighten the retaining screws.
2. Clip the sign rear panel into the retaining slots on the rear of the
sign side panels (see Figure 1 below).
3. Lift the sign unit on to the top of the cabinet and connect the
sign 3-pole plug into the roof top power supply socket.
4. Clip the sign into the retaining slots on the front of each side
panel and pull the sign unit firmly down. Ensure the two screws
in the back of the sign unit fit into slots in the cabinet top angle
bracket and then tighten all the screws.
5. Turn the sign retaining clips on top of each side panel, to hold
the sign unit firmly in position (see Figure 2 below).

3. 1 Lighting
Cabinet Interior lights
Depending on the model cabinet, the chiller has either one or two
interior side lights. Each side light houses a 35 Watt T5 fluorescent
tube (Ø16mm x 1450mm), which may be replaced without removing
shelves or product from the cabinet. To replace the interior side light
fluorescent tube:
1. Disconnect the cabinet from the mains power supply.
2. Remove the side light diffuser, by compressing the back
section of the diffuser until it disengages from the aluminium
housing and then push the diffuser back (see Figure 4 below).
3. The fluorescent tube can now be removed. Revolve the tube
until the pin position allows withdrawal.
4. When refitting the new fluorescent tube ensure the printing on
the tube is at the bottom, as the tube orientation is important.
5. When refitting the diffuser, engage the back section into the
housing, and then compress and snap the front section of
diffuser back into place working down the full length of the light.

1.4 Fitting the Shelves
The chiller is supplied with five cabinet shelves, which may be
positioned at different heights to suit various products. Depending
on the model cabinet, each shelf is held in place with either four or
six shelf clips, which engage in the shelf support strips. The support
strips are marked with a ‘+’ for easy location of shelf clips.
To fit the cabinet shelves:
1. Unpack the shelves and shelf clips from inside the cabinet.
2. Establish the desired position for the shelves and securely
engage a shelf clip in each of the shelf support strips (see
Figure 3 below).
3. Sit the shelves onto the shelf support clips.
Loading Product
For even cooling and efficient operation, allow air space around
packages etc. Do not allow products to overhang the front of the
shelf as this could prevent the doors from shutting or cause glass
breakage. Leave an airspace of at least 75mm (3") above product
loaded on the top shelf.

2. 1 Cabinet Operation
Connect the cabinet to themains powersupplyandcheck operation
of the refrigeration unit and cabinet lighting.
NOTE: After moving the chiller,allowthecabinettostandforatleast
30 minutes before connecting to the power supply.
Refrigeration Unit
The compressor, and evaporator and condenser fans should all
operate continuously from the time the cabinet is plugged in. This
may be verified by listening for compressor switch on and checking
for air movement inside the cabinet.
The compressor and condenser fans should switch off when the
cabinet internal temperature reaches approximately 2°C. and on
again at approximately 4°C. The internal cabinet air will continue to
circulate at all times.
Lighting
The sign light and cabinet interior lights will go on when the cabinet
is plugged in, and will stay on permanently. The fluorescent lights
will require a period of time to stabilise following initial start up.
