1 Installation
Safety First Always observe safety precautions when using any electrical appliance.
Read these instructions carefully and retain them for future reference.
When the appliance is used by or near young children or infirm persons,
close supervision is necessary, especially to ensure children do not play with it.
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 the voltage specified on the rating label.
Ensure the appliance has adequate ventilation as this is essential to
economical, high performance.
Be careful not to touch moving parts and hot surfaces.
For your own safety and that of others, ensure that all electrical work is
done by authorised personnel.
If the power supply flexible cord becomes damaged, it must be replaced
by an authorised service agent or similarly qualified person in order to avoid a hazard.
Ensure all necessary safety precautions are observed during installation
or removal of the refrigeration unit.
The appliance is not designed to be stable while in motion. Use extreme
caution when moving or transporting it.
Do not store explosive substances such as aerosol cans with a
flammable propellant in this appliance.
CAUTION
Never overload the power supply, which could damage the
chiller and product. See the rating label inside the cabinet for
the safe power supply and current draw.
WARNING
Always disconnect the chiller from the mains power supply
before cleaning or maintenance.

User Manual
Positioning the Cabinet
Location When positioning the cabinet, avoid direct sunlight and warm draughts etc.
The cabinet must NOT be situated where it is affected by warm or hot air (above 40
°C) from adjacent equipment, as this will compromise the airflow
and performance of the chiller.
The cabinet must be positioned on a level surface for the doors to shut and seal correctly, and to prevent the condensate tray from overflowing. Adequate allowance should be made for door opening.
Installation
Guidelines
The maximum recommended ambient temperature (at place of installation) for the chiller is 32°C. This chiller will generally use less power when installed in a cooler location.
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.
Do not overload the power supply. See the rating label inside the
cabinet for power supply and current draw.
Power Supply The chiller is supplied with a 1.8m flexible power cord fitted with a 3-pin plug,
which exits out the rear of the refrigeration unit. The power cord should be retrieved before the cabinet is positioned, as wall and partitions may make access difficult.
WARNING:
Heat dispersion and ventilation of the refrigeration unit cannot
be overstressed. The air surrounding the condenser must not
exceed 40°C.
WARNING:
Do NOT overload the power supply. See the rating label inside
the cabinet for power supply and current draw.

Ventilation Adequate ventilation is essential. For efficient operation of the chiller, it is
essential that adequate ventilation be provided above the refrigeration unit. Never store cardboard cartons or other items on top of the refrigeration unit.
When positioning the cabinet, a gap of at least 200mm must be left above the refrigeration unit. The back of the cabinet can be positioned hard against a wall, however a gap of 50mm is recommended to prevent moisture build­up.
IMPORTANT:
To ensure efficient and reliable operation, a minimum of 200mm
clear ventilation space is required above the refrigeration unit.

Shelving
The cabinet is supplied with two sets of shelves and shelf support brackets per door. The shelves can be positioned at different heights to suit various products.
To fit the shelves
Loading
Product
The cabinet should be left running for 30 minutes before loading with product. When loading the cabinet shelves with product:
Ensure all shelves are securely fitted (see above).Allow air space around all the product, to ensure even cooling and
efficient operation of the chiller.
Do not allow products to overhang the front of the shelf as this could
prevent the doors from shutting. Leave an airspace of at least 50mm above product loaded on the top shelf.
Products must NOT be stored on the floor of the cabinet.
Do not exceed a maximum loading of 20kg per shelf.
Remove some product if the shelves are flexing or bending.
Door Lock Each door has a key lock, located at the top of the door, on the same side
as the handle.
1. Unpack the shelving items from inside the cabinet.
2. Establish the desired position for each of the shelves, based on the height of the product intended to go on each shelf.
3. Fit the stainless steel tray slides into the corresponding slots in both the front and back support rails. Each shelf requires two tray slides.
4. Slide each wire shelf into the corresponding pair of tray slides.

2 Operation
Automatic Start-Up
Connect the cabinet to the mains power supply and check operation of the refrigeration unit, electronic controller and cabinet lighting.
Refrigeration
Unit
The refrigeration unit evaporator and condenser fans should all operate continuously from the time the cabinet is plugged in. The internal cabinet air will continue to circulate at all times.
The compressor will start after approximately one minute. The compressor will switch off when the cabinet internal temperature reaches approximately
-21°C, and on again at approximately -18°C.
Electronic Controller
When the cabinet is connected to the power supply:
Cabinet
Lighting
The interior lighting will go on when a cabinet door is opened. To replace an LED tube see service instructions on page 14.
The electronic controller will display the cabinet temperature.
The ‘Compressor’ and ‘Fan’ LEDs will indicate when the compressor and evaporator fan are operating.

Controller Operation
The operation of this freezer is controlled by a pre-programmed microproc­essor. The Microprocessor display indicates the temperature of the cabinet ambient probe, except during a defrost where the temperature of the cabinet probe is locked in, and during an alarm condition.
At alarm activation, the display indicates the type of alarm signal, and an audible alarm sounds. The alarm can be muted by pressing the PRG/mute key on the controller.
Controller
Alarms
A flashing LED indicates an alarm. The following is a list of alarms the controller displays:
* NOTE: Alarm ‘HI’ may activate during initial pull-down cycle, after being first powered up. The alarm can be muted and will automatically reset when the cabinet passes the alarm setpoint.
To reset an alarm

Data acquisition failure
1. Clean the condenser radiator fins and remove any obstruction to the airflow.
2. Ensure the cabinet environment is below 32°C.
3. Unplug the cabinet from the power supply for 1 minute, then re-connect to the power supply.
4. Check cabinet product loading to ensure ventilation slots are not blocked and that product does not overhang the shelves.
5. If alarm persists, contact a SKOPE authorised refrigeration service agent.

Cleaning
Cabinet 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 required.
Condenser
Coil
The condenser coil is situated behind the unit front panel. The condenser coil MUST be kept clean for reliable operation and to minimise power consumption (a blocked condenser can double power consumption).
To ensure trouble free performance, the condenser coil should be brushed clean once a month and blown clean by qualified service personnel every six months.
Over time, dust may accumulate within the condenser that cannot be removed with a brush. if this occurs, contact SKOPE to arrange for a SKOPE Authorised Service Agent to clean the condenser with compressed air.
To access the condenser coil
CAUTION
Disconnect the cabinet from the mains power supply before
cleaning the condenser coil or washing the cabinet.
1. Disconnect the chiller from the mains power supply.
2. Remove the refrigeration unit front panel from the cabinet by pulling the bottom of the panel out to unclip from the side panels and then lift the panel up off the cabinet. Refitting the front panel is a reversal of this procedure.
3. The condenser coil is now accessible for cleaning.
