2.1 Positioning of Machine
Mains Flex
The mains flex exits below the rear panel behind the refrigeration
units. For convenience, the flex should be retrieved before the
machine is positioned, when walls and partitions may make access
difficult.
Siting chiller
When siting the chiller, avoid direct sunlight, and warm draughts etc.
Adequate allowance should be made for door openings. The cabinet
must be positioned on a level surface for the door to shut and seal
correctly, and to prevent the condensate tray from overflowing.
Remove all packaging material from the shelves. Clip shelf support
brackets into the shelf support strips at the desired heights, and
relocate shelves.
Ventilation
When positioning the chiller, a gap must be left between the top of
the sign panels and ceiling, of at least 200mm. For efficient opera
tion of the chiller, it is essential that adequate ventilation be provided
above the refrigeration unit.
Maximum recommended operating
ambient temperature is 40°C.
Never store cardboard cartons or other items on top of the
refrigeration unit.

3.1 Safety Information
When using any electrical appliance, safety precautions should
always be observed. Read these instructions carefully, and retain for
future reference.
Warning:
Do NOT overload power supply.
Machine rated at 5.2 Amps @ 240 Volts
• Do not use this appliance for other than its intended use.
• Only use this appliance with voltage specified on the rating label.
• Ensure adequate ventilation of SKOPE refrigeration unit.
• Condenser coil MUST be kept clean. To ensure trouble free
performance, it is recommended that on a regular basis the unit
be isolated from the power supply and a vacuum cleaner used to
remove dust and fluff from the condenser.
• Be careful not to touch moving parts.
• Do NOT cover the grilles or block the entry or exhaust of airflow
by placing objects up against or on top of refrigeration unit.
• Do NOT probe any opening.
• 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 refrigeration unit is required to be installed or removed
from the cabinet, ensure all necessary safety precautions are
observed.
Caution:
Disconnect the cabinet from mains power supply before
attempting any electrical servicing, cleaning or maintenance.
OPERATION

SK1000
SKOPE Top Mounted Vertical Chiller
3.2 Operation of Machine
Plug in machine and check operation of the refrigeration unit,
illuminated sign, and cabinet lights. The compressor, evaporator and
condenser fans should all operate initially. This may be verified by
listening for compressor switch-on, and by checking air movement
around the refrigeration unit and out of the rear duct inside the
cabinet.
Checking Operation
• Compressor and condenser fan should switch off when cabinet
internal temperature reaches approximately +1°C, and on again
at approximately +4°C. The internal cabinet air will continue to
circulate at all times.
• The lights which illuminate the top sign and cabinet interior are
permanently on.
• Ensure the door gaskets form a good seal with the cabinet.
3.3 Loading
Shelves may be positioned at different heights to suit various products. Always ensure that the shelf clips are securely engaged in
each of the four shelf support strips. Support strips are marked ‘+’
for easy location of shelf clips.
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 door from shutting or cause glass
breakage. Leave an airspace of at least 75mm (3") above packages
etc. on the top shelf.

3.4 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 exterior of the cabinet may
be waxed with automobile polish for extra protection.
Do not wipe the sealant off the door gaskets, as the sealant ensures
the door gaskets form a good seal with 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. Clean the condenser coil with a brush and vacuum
cleaner regularly.
Access to the condenser coil is gained by removing the sign unit.
See page 16 for instructions on how to remove the sign unit.
The preventative maintenance recommendation is to clean the
condenser at one to three month intervals. Certain conditions may
necessitate more regular attendance, such as dusty, humid or
steamy environments.
Caution:
The cabinet MUST be disconnected from the mains power
supply before cleaning the condenser coil.
3.5 Servicing
Servicing should be carried out by an authorised service agent.

4.1 Interior Side Light
The fluorescent tube and starter are located inside the interior side
light, and may be replaced without removing shelves or product from
the cabinet. To replace the fluorescent tube and starter:
1. Disconnect cabinet from power supply.
2. Compress the back section of the diffuser, so that it disengages
from the aluminium housing and push the diffuser back, to gain
access to the light.
3. The fluorescent tube and starter can now be removed. Revolve
the tube until the pin position allows withdrawal.
4. Replace tube and starter as necessary (see p.33 for spares).
5. When refitting the diffuser, engage back section into side light
housing, and compress and snap front section of diffuser back
into place working progressively down the full length of light.

4.2 Glass Doors
Alignment
Door alignment can be achieved by releasing the bottom hinge
bracket, which is provided with slots allowing alignment adjustment,
enabling the bottom of the door to be moved sideways.
Gasket replacement
The door gaskets clip into the door gasket retainer extrusion and
may be removed for repair or replacement simply by peeling from
frame, starting at a corner.
New gaskets, when fitted, may be lightly lubricated with a clear silicone grease or similar compound. This will lessen the possibility of
the gasket rolling. Should the gasket be out of shape when in place,
use hot air (i.e. from hair drier) to realign.
