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)

5. USER 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.
