6.2.3 Remove any dust or dirt using a vacuum cleaner. Particular attention should
be paid to the inside of the louvre grills and the condensor fins. DO NOT
use a metal brush to clean the condensor fins as they may be damaged.
6.3 DISINFECTING
It is recommended that the chiller is disinfected on a regular basis to prevent
the build up of contaminants.
WARNING Many disinfecting products are acid or alkali corrosive substances.
Always follow the manufacturers instructions for use and DO NOT exceed
the recommended dosing concentrations or times. Always wear suitable
protective clothing, disposable gloves and safety glasses are a minimum
requirement for most solutions.
6.3.1 Prepare the disinfecting solution in accordance with the manufacturers
instructions. At least 5 litres of mixed solution will be required.
6.3.2 If fitted with a chlorine filter the filter cartridge must be bypassed.
6.3.3 Connect the container holding the disinfecting solution to the inlet of the
water chiller via a small pump.
6.3.4 Start the pump and operate the outlet to allow the disinfecting solution to
enter the chiller. Allow approximately 4 litres of solution to enter the chiller
to ensure the chilling coil and all internal pipework is filled with disinfecting
solution. Close the outlets and stop the pump.
6.3.5 Allow the solution to stand within the chiller for the recommended dosing
time (refer to manufacturers instructions).
6.3.5 Disconnect the disinfecting solution filling arrangement. Reconnect the
chlorine filter or fit a new filter cartridge. Reconnect the mains water supply
and turn it on.
6.3.6 At least 15 litres of water should be flushed through the chiller and outlets
to ensure all traces of the disinfecting solution are removed from the system
before further use for drinking water.
6.3.7 Other disinfecting processes may be suitable (eg. ozone treatment), consult
the manufacturers for further advice.
6.4 EMPTYING ICE BANK CONTAINER
6.4.1 Disconnect mains cable from the socket. To empty the ice bank you can
unclip the clear tube at the rear of the unit: Allow the water to flow from
the unit into a recepticle or drain. Once flow has stopped replace the tube
back into clips.
