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 hot air from
adjacent equipment, as this will compromise the airflow and performance of
the chiller.
Ventilation For efficient operation of the chiller, it is essential that adequate ventilation
be provided around the refrigeration unit. The maximum recommended
ambient temperature (at place of installation) is 40°C, although the chiller
will generally use less power when installed in a cooler location.
Installation
Guidelines When installing the chiller:
Ensure the cabinet is positioned on a level surface so the door shuts
and seals correctly and to prevent the condensate tray from
overflowing.
Allow adequate space for door opening. The self-closing door has an
internal torsion bar which is pretensioned at the factory.
Do not overload the power supply (see the rating label inside the
cabinet for power supply and current draw)
Power Cord The chiller is supplied with a 3.0m flexible power cord fitted with a 3-pin plug.
For transit purposes the power cord is clipped to the roof of the cabinet (see
Figure 1 below). For convenience, the cord should be retrieved before the
machine is positioned, when walls and partitions may make access difficult.
Warning:
For efficient operation of the chiller it is essential that adequate
ventilation be provided around the refrigeration unit.

Figure 2 below).
3. Open the cabinet doors wide open (this is to allow fitting of the kick
panel). Sit the kick panel over the two corner bottom locating brackets
and push on to the two top keyhole fixing screws. Tighten both the
screws. Ensure the controller cables are well clear of any sharp objects
on the refrigeration unit.
Fitting the Illuminated Sign
For transit purposes the illuminated sign is packed inside the cabinet.
To fit the illuminated sign
1. Loosen the four retaining screws on top of cabinet, and fit both the sign
side panels over the screws. Slide the panels forward, flush with edges
of the cabinet, and tighten the screws.
2. Clip the sign rear panel into retaining slots on the rear of the sign sides
(see Figure 5 over page).
3. Fit sign unit by engaging clips into both retaining slots on the front of
each side panel, and pull sign unit firmly down. Ensure the two screws
in the back of the sign unit fit into slots in the cabinet top angle bracket,
and then tighten all the screws.

2Operation
Automatic Start-Up
After the cabinet has been positioned in a suitable place, plug it in and check
the following activity.
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 product for even cooling and efficient
operation of the chiller.
Leave an airspace of at least 15mm above product on the top shelf.
Do not allow products to overhang the front of the shelves as this could
effect airflow and prevent the doors from shutting properly.
Do not exceed a maximum loading of 20kg per shelf.
Remove some product if the shelves are flexing or bending.
Item Activity
Lighting
The lights which illuminate the top sign and cabinet interior will
initially come on when the machine is turned on. The lights will
require a period of time to stabilise following initial start up.
On some models the lights can be turned off via the UP/AUX
button on the electronic controller (see next page for details).
Electronic
Controller
The electronic controller, located in the front kick panel, will
either display the internal cabinet temperature or the controller
set point. The compressor ‘ON’ icon will indicate when the
compressor is operating (see controller display on next page).
Compressor,
Evaporator Fans
and Condenser
Fan
The compressor, and evaporator and condenser fans should
all operate initially. This may be verified by listening for
compressor switch on and checking air movement out of the
slots in the front kick panel. The internal cabinet air will
continue to circulate at all times, as the evaporator fan
operates continuously.
The compressor should switch off when the cabinet internal
temperature reaches approximately +2°C, and switch on
again at approximately +4°C.
The condenser fan operates continuously. A fan reversing
device, reverses the condenser fan motor for a period of time
during the compressor ‘off-cycle’. This rotation change is to
assist with self-cleaning of the condenser coil.
