3. INSTALLATION

®

SUPER ASTRA

Please follow these instructions carefully. Only if the
beverage cooler is properly installed will trouble free
operation and customer satisfaction be achieved.

NOTE – the cooler is fully automatic, therefore the
electrical supply must not be interrupted (unless access
for maintenance is required), otherwise reduced
performance and reliability will occur.

HANDLING AND TRANSPORTATION

Keep the unit in an upright position and do not drag
over rough floors or down steps.

On receipt, unpack the unit carefully and inspect for any
superficial damage which the unit may have sustained in
transit. Record the nature of damage on the Courier’s
Delivery Note and at the same time inform your
supplier.

Once the unit is in position, do not move when filled
with water.

INSTALLATION AND OPERATION

1. General

Installation must only be carried out by a suitably
trained person and comply with national and local codes
for connection to electrical supplies.

It is recommended that the mains electrical supply is
protected by an RCCB.

2. Siting

The cooler is designed for indoor use only, in ambients
between 5°C and 43°C and should not be exposed to
water spillage, spray, steam or high humidity (in excess
of 90% rh).

Allow 80mm clearance around the unit to aid air
circulation and keep the front of the unit clear to allow
an unimpeded fresh air supply to enter the cooler.

Air vents and louvres should never be obstructed or
blocked, also access should be possible to the unit lid
for ease of service.

Site the cooler on a firm level support, protect from
physical damage and do no place items on top. Locate
the cooler within 2 metres of an earthed, switched
socket of correct rating (indicated on rating plate) which
should be accessible for isolation of the equipment. The
socket should be installed to current IEE regulations.

Locate the cooler as near to the dispense point as
possible to reduce heat pick up by the product after it
has left the unit.

3. Installation

The appliance must be earthed.
With the unit unpacked and in position, remove all coil
caps.
Ensure all panels are secured in position.

1. Remove the overflow bung from the tube sited on

the front of the unit. The overflow position is
indicated on the front label.

2. Rotate the filler disc cover, situated on the unit lid,

until the hole is aligned with the filler tube, allowing
water to be poured into the unit.
Do not use de-ionized water or add any substance to
the water.
Do not leave hose pipes unattended while filling the
water bath as the unit may become flooded.

3. Fill the bath, through the filler funnel, with cool,

clean water until the water flows from the overflow.

4. To allow the cooler to operate during installation

and form an ice reserve, pump connections (located
on the front of the cooler marked FLOW and
RETURN) for still water recirculation must be
looped together with a pipe. This will prevent water
being pumped from the water bath. The cooler can
now be switched ON. Time to create an ice reserve
is between 2 to 5 hours depending on unit type and
ambient temperature.

5. For plumbing connections follow the label

instructions sited on the front of the cooler.
The product supply is connected to the product coil
inlets, marked IN.
The outlets from the product coils, marked OUT,
should be connected to dispensing point(s).
The remaining water recirculation tails should be
connected to the python. Initially switch the unit
OFF, remove the loop previously fitted and connect
the python water recirculation lines to the cooler.
The other end of the python must have the two
python tubes connected to allow water to recirculate
from the cooler water bath through the python
enabling the product in the python to remain cool.

6. Once the connections are made, the cooler can be

switched ON. This will allow the python to prime
with water. The cooler must then be switched OFF
and the water bath ‘topped up’ following the
procedure indicated earlier.
When the water has stopped flowing from the
overflow, replace the bung and rotate the filler disc
until the filler tube is covered.
Never allow the water pump to run dry – caused by
priming a large python with water from the unit.
This is to ensure the correct water level is
maintained in the cooler.

5. USER MAINTENANCE

7. Insulate the cooled product outlet tubes to reduce
heat pick up between the cooler and dispense tap.

4. Operation

Super Astra incorporates the following features
according to model. Refer to the Super Astra product
data sheet for details:–

Still water recirculation

Water is pumped from the water bath to the dispense
point to maintain product temperature in the python.

Summer/Winter Waterbath Control (where fitted)

This control is sited inside the unit, accessible by
removal of the lid. SUMMER setting will build an
icebank, while WINTER maintains a thermostatically

controlled bath of cold water only.

4. SERVICE INFORMATION

There are no user serviceable items inside the
equipment. Maintenance and repairs must only be
carried out by a properly qualified and trained person.

Switch off the mains electrical supply and unplug the
equipment if it malfunctions, suffers spillage, or
physical damage. Do not switch the unit ‘off’ and ‘on’
within five minutes.

In the event of component failure, SWITCH OFF AND
UNPLUG the unit.

Access to:­The icebank, thermostats, agitator/pump and condenser

fan can be made be removing the cooler lid.
The compressor electrics by the removal of the lid and

left rear panel.
Pump removal/refitting – undo pump fasteners,

allowing removal from lid. Lift from lid rotating the
pump assembly to allow attached flow tube to unwind.
Remove clip (if fitted) which secures the flow tube to
the pump body. Fitting of new pump (fit new clip if
required) and rotate pump assembly to take up excess
pipe length – as assembly before removal.

Only use Cornelius parts for cooler maintenance.

Switch off and unplug the unit during maintenance
operations.

Do not switch the unit ‘off’ and ‘on’ within five
minutes.

Do not attempt to remove any protective covers.
Ensure grilles and condenser fins remain unobstructed

and free from particles at all times to ensure reliable and
consistent operation. A soft brush or vacuum cleaner
may be used for cleaning.

If the cooler becomes noisy – makes a ‘gurgling’ sound,
this is due to vortexing in the water bath caused by a
low water level and will result in reduced cooling of the
beverage. To remedy, follow the procedure below:-

1. Check the python and connections for leaks.

2. If leaks are found call the service engineer.

3. If no leaks are found follow the instructions for
filling the water bath outlined in Section 3 –
Installation.

Sanitise the pipelines by flushing with water, followed
by a chlorinated alkaline sanitizing agent and finally
potable water flush when product tainting is evident or
when advised by the equipment installer or beverage
supplier. This can be at the same time as the ordinary
service lines are cleaned, therefore no dismantling of the
cooler is required. It is important that the sanitizing
agent manufacturer’s procedure and safety precautions
are followed. Under no circumstances should boiling
water or steam be used with this unit as it may result in
permanent damage to the thermostat and plastic product
tubing. The maximum water temperature permissible is
43°C.

Ensure that objects are not placed on top of the unit and
vents or grills are never obstructed as this may affect the
unit’s function.

Cornelius recommend periodic testing of electrical
equipment, which should be carried out by a competent
person.
