Do not use this appliance for other than its intended use.
Do not insert fingers/foreign objects into any holes.
Only use this appliance with the voltage specified on the cabinet 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.
If the cabinet is to be scrapped, ensure the cabinet is unplugged from

User Manual
Positioning the Chiller
Climate Class The chiller is designed to operate within a climate class 3 environment (25°C
@ 60% relative humidity).
Location Select a suitable location for the chiller away from direct sunlight and heat
sources, e.g. radiators, baseboard heaters, cooking appliances.
This chiller is intended to sit on a raised benchtop. Ensure the bench will
support the chiller which could weigh up to 120kg when fully loaded.
The front door (electronic controller side) is fitted with a door switch. Position
the chiller so that the front door opens to the customer side of the benchtop.
This enables the door switch to detect customer door openings.
Ventilation Ensure adequate ventilation is provided around the chiller. The chiller is
designed for free-standing installation only. Do not place the chiller in a
recess or another cabinet.
Installation
Guidelines
When installing the chiller:
Remove all packaging material from the inside and outside the chiller.
Ensure the chiller is positioned on a level surface so the doors shut and
seal correctly, and to prevent the condensate tray from overflowing.
Ensure the installation surface is capable of supporting the fully loaded
chiller.
Allow adequate space for door opening. The self-closing doors have
pre-tensioned internal torsion bars.
Do not overload the power supply (see the rating label inside the
cabinet for power supply and current draw information).
Position the front door (electronic controller side) towards the customer.
Power Cord The chiller is fitted with a 2 metre flexible power cord with a 3-pin plug, which
exits the front of the refrigeration system.
Levelling Adjust the four stabiliser feet (see image below) to ensure the chiller sits on
a level surface so that both doors shut and seal correctly. Turn the stabiliser
foot clockwise to raise and anti-clockwise to lower the cabinet.

IMPORTANT
Ensure the controller faces the customer side of the benchtop.

2 Operation
Automatic Start-up
After the chiller has been positioned in a suitable place, plug it in and check
the following activity.
Loading Product
Let the chiller run for 30 minutes before loading it with product the first time.
When loading the cabinet shelves with product:
Allow adequate air space around each item to ensure even cooling and
efficient operation of the chiller.
Remove some product if the shelves are flexing. The maximum loading
for each shelf is 25kg.
Do not let anything overhang the shelves, this might stop the doors from
shutting or even break something.
Door Lock
The chiller is fitted with security door locks. Use the supplied keys to lock
and unlock the door as necessary.
Item Activity
Condenser fan The condenser fan starts immediately and can be heard.
Evaporator fan
The evaporator fan will start after a few seconds. To verify,
check that the fan light is flashing on the electronic
controller. The evaporator fan turns off when the front door
(electronic controller) is opened and turns on again when
the front door is closed.
Sign and interior LED
lighting
The lights that illuminate the sign and cabinet interior will
come on when the chiller is turned on.
Compressor
The compressor will start after a few minutes. To verify,
check that the compressor light is flashing on the electronic
controller. The compressor turns off when the product
temperature reaches +2°C and turns on when the product
temperature rises to +5°C.

User Manual
Electronic Controller
Introduction The electronic controller controls and displays the chiller temperature, and
signals temperature alarms. It uses temperature probes and a door switch
to collect data and runs the chiller accordingly. The electronic controller
automatically switches the chiller between ‘Day’ and ‘Night’ modes
depending on chiller usage. The electronic controller is pre-programmed
and requires no initial setup or additional programming. SKOPE does not
recommend that the settings be changed unless it is absolutely necessary.
To ensure efficient operation, the electronic controller forces a defrost cycle
when required.
Faceplate Because the electronic controller plays such an important role, it’s helpful to
know the parts of the faceplate you may use.
Door Switch The front door (electronic controller side) is fitted with a door switch which
tells the electronic controller when the door is opened and closed. If the door
is opened for an extended period an alarm will sound. Press the alarm mute
button on the electronic controller to mute the alarm.

Cleaning
Many commercially available cleaning products contain solvents that may
damage the plastic components of the chiller and cause them to crack. Do
not use abrasive or corrosive cleaners or boiling water.
Wash with warm water and wipe down the chiller with a soft cloth or sponge,
then rinse with clean warm water and dry with a soft cloth. If required, lift up
and remove the shelves to help with cleaning. Do not flush the cabinet with
water.
Shelves
