2.1Positioning of Machine
Castors / Legs
If your SKOPE Backbar chiller has been supplied with either the
optional adjustable height castors or adjustable legs (packed with
the cabinet), they should be fitted to the base of the cabinet before
final positioning of the chiller.
Siting chiller
When installing the chiller it is important to consider the location and
physical environment where the chiller is to be positioned. When
siting the chiller, avoid direct sunlight and warm draughts etc.
Maximumrecommended operating ambient temperature is 32°Cat
65% RH, and for tropical machines is 40°C at 75%RH.
Adequate allowance should be made for door opening. The chiller
must be positioned on alevel surface for the doors to shut and seal
correctly, and to prevent the condensate tray from overflowing.
Shelves
Remove all packaging material from the shelves. Clip the shelf
support brackets into the shelf support strips, at the desired heights,
and fit the shelves.
Shelves may be positioned at different heights to suit various
products. Always ensure that the shelf clips are securely engaged in
each of the shelf support strips. Shelf support strips are marked ‘+’
for easy location of shelf clips.

Mains flex
The mains flex exits below the refrigeration unit front cover. Initial
retrieval of the mains flex is from inside the refrigeration unit
compartment, behind the unit front cover. To retrieve the mains flex:
1.Open the unit front cover: firstly undo the fixing screw at bottom
of cover, then lift the cover up from the bottomand swing open.
2.Pull the mains flex fully out from the unit compartment, and
remove the rubber band.
3.Push the unit end of flex into the grey plastic clip beside the
front cover bottom hinge, and close the plastic clip over the
flex, ensuring it is held firmly in place.
4.The mains flex can now be run under the cabinet, and plugged
into a power socket
5.Close the unit front cover: by lifting the cover up from the
bottom and pushing firmly closed. Remember to refit the
bottom fixing screw.

2.2Refrigeration System
Drain
A500mm long, 19mm O.D. PVC drain hose is supplied. All drainage
is to conform to local regulations, covering removal of condensate to
waste water. Ensure drain is trapped with adequate fall. Venting the
drain may be required for a restrictive run.
Refrigeration lines
A 1/4” liquid line, and 3/8” suction line are provided to attach pipe
lines to. The suction lines must be insulated.
NOTE:The electronic controller supplied with the cabinet can switch
a solenoid. No solenoid is supplied with the remote unit.
Refrigeration Practice
Installation must be performed by arefrigeration tradesperson, to an
appropriate standard complying with all local regulations.
Performance depends on the overall installation (including
condensing unit). Cabinet suitability must always be quantified for
the application. The final responsibility for condensing unit
performance and component selection rest with the installer. The
installer must check matters such as:
•Heat load
•Refrigeration load
•Variable operating conditions (usage, ambient, humidity)
•Refrigeration pipe sizing
•Refrigeration pipe length (distance, elevation, pressure drop)
•Location and ventilation (cabinet and condensing unit)
•Drainage

•Power supply
•Unit is fully evacuated prior to charging
•All cabinet penetrations are sealed
Electrical
The cabinet is supplied with a 3-core 10 Amp mains flex and plug.
The cabinet lighting and centre pillar heater elements are protected
by a 3 Amp fuse, located in the unit junction box.
If a solenoid is fitted and controlled by the electronic controller, the
solenoid will need connected to the connector block inside the unit
junction box.

3.1Safety nformation
When using any electrical appliance, safety precautions should
always be observed. Read these instructions carefully, and retain for
future reference.
•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.
•Be careful not to touch moving parts and hot surfaces.
•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.
•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.
Warning:
Do NOT overload power supply.
Caution:
Disconnect machine mainspower supply before attempting to
perform any electrical service or maintenance.

12 BB380r-2, BB580r-3, BB780r-4
SKOPE Backbar Remote Chillers
3.2Operation of Machine
Plug in machine and check operation of the refrigeration unit and
lights. The electronic controller and evaporator fan motor should
operate initially. Note: If the solenoid valve is fitted, and operated by
electronic control, then the solenoid should open when compressor
indicator is shown.
Checking operation
•The solenoid / compressor relay 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 light switch, located next to the electronic controller on the
refrigeration unit front cover, activates the cabinet interior
lighting and can be switched on or off as required.
•For efficient operation, ensure the door gaskets form a good
seal with the cabinet.
3.3Loading
For even cooling and efficient operation, allow air space around
packages etc. Do not allow products to overhang the front of shelf
as this could prevent the door fromshutting or cause glass
breakage.
mportant:
Leave air space above product on the top shelf, as well as a
gap of approximately 50mm next to the return air grille
between the cabinet interior and the refrigeration unit
compartment.

3.4Cleaning
When necessary, wash both interior and exterior of cabinet with
soapy water. Exterior of cabinet may be waxed with automobile
polish for extra protection. Ensure the machine is disconnected from
the mains power supply before washing the cabinet with water.
Do not wipe the sealant off the swing door gaskets, as the sealant
ensures the door gaskets forma good seal with the cabinet.
Caution:
Disconnect machine from mains power supply before washing
the cabinet with water.
3.5Servicing
Servicing should be carried out by an authorised service agent.
Detailed service and spares information is available in the SKOPE
