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
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.
Always ensure that the top of the cabinet is shielded from impact and
moisture, with either a SKOPE provided bench top or with a custom or
existing bench top.
Ventilation For efficient operation of the chiller, it is essential that adequate ventilation
be provided around the front of the refrigeration unit. Normal operating
conditions should not exceed 40°C at 65% RH.
It is critical that the hot refrigeration exhaust air is not restricted and that it
can easily flow out and away from the front of the cabinet.
Never store cardboard cartons or other items in front of the refrigeration unit
and the ventilation slots in the unit front cover must be kept clear at all times.
When installing the cabinet
Avoid direct sunlight and warm draughts etc.
Allow adequate space for the door/s and/or drawer/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.
Power Supply The chiller is supplied with a 1.8m flexible power cord and plug, which for
transit purposes is located inside a compartment in the rear of the cabinet
(see Figure 5 below).
Before final positioning of the chiller, pull the power cord out from the rear
compartment and connect to the power supply. For convenience, any
surplus cord length may be left inside the cabinet compartment.
Once the chiller has been installed it can be disconnected from the mains
power supply by turning off the cabinet isolating switch and unplugging the
unit supply isolation flex, located inside the refrigeration unit compartment
(see Figure 6 below).

per door. The shelves can be positioned at different heights to suit various
products.
To fit the shelves
Loading
Product
The chiller should be left running for 30 minutes before loading with product.
When loading the cabinet shelves with product:
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 75mm
above product loaded on the top shelf.
Do not exceed a maximum loading of 20kg per shelf.
Remove some product if the shelves are flexing or bending.
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 shelf support
brackets into the
corresponding slots in
both the front and back
support rails. Each shelf
requires two support
brackets.
4. Slide each shelf into the
support brackets.

2Operation
Automatic Start-Up
Connect the cabinet to the mains power supply and check operation of the
refrigeration unit, electronic controller and cabinet lighting.
Ensure the cabinet isolating switch, located inside the refrigeration unit
compartment, is turned on (see Figure 6 on page 6).
Refrigeration
Unit
The compressor, and the condenser and evaporator fans should all operate
within two minutes 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 fan will
switch off when the cabinet internal temperature reaches 2°C.
Electronic
Controller
When the cabinet is connected to the power supply, the electronic controller
will display the current cabinet temperature. The compressor LED will
indicate the compressor is operating and the evaporator fan LED will
normally come on within two minutes (see page 9 for controller display).
To ensure efficient operation, the electronic controller forces six hourly
defrosts. During the defrost cycle, the compressor and condenser fan switch
off and the evaporator fan stays on.
Cabinet
Lighting
The interior lighting will go on when a cabinet door or top drawer is opened.
The only time that a light should not turn on is either if an LED tube is faulty
or the ‘CHt’ high temperature shutdown alarm has been activated (see
pages 11 for controller alarms). To replace a LED tube see service
instructions on page 12.
HACCP If Hazard Analysis Critical Control (HACCP) functions are required, to
monitor food storage temperature, please contact SKOPE to arrange for an
authorised SKOPE service technician to setup the electronic controller.
IMPORTANT
If the cabinet has been on its back, leave for 30 minutes
before running.
