5. Chiller Sanitisation & Cleaning
This procedure should only be carried out by persons trained by Marco or their approved distributors.
The operation of sterilisation has to be carried out every time the refrigerator is installed and:
- after every 6 months of use.
- every time the water filter is changed
- after an inoperative period of one or more weeks. If the refrigerator is installed in Hospitals, Schools, Care homes for the elderly,
or Clinics, it is recommended to sterilise it every 3 months.
Use a suitable product that is both a detergent and a sanitiser, to be mixed with water in the proportions recommended by the
manufacturer. We recommend you to use Bioguard Internal Watercooler Sanitiser Solution (12ml dosage) . We suggest
changing the product type on a regular basis, to prevent resistant bacteria. Never exceed the contact times and maximum dosage
concentrations recommended by the manufacturer. Once the sanitizing fluid has flowed through and cleaned the lines, they must
be thoroughly rinsed with mains water until all the sanitizer has been completely eliminated. Check the pH of the outlet water is the
same as the pH of the inlet water (use litmus paper or a pH meter).
PREPARE THE COOLER FOR SANITISATION
1. Turn on water and flush at least 4 liters (1 gallon) through entire system (plain and carbonated water circuits).
2. Disconnect water line from main water supply.
3. Dispense both plain and carbonated water, until only CO2 is dispensed.
4. Close the CO2 cylinder and dispense carbonated water to remove CO2 pressure completely.
SANITISING
1. Turn off Electrical Power Supply.
2. Replace the filter cartridge with a sanitizing filter recommended by Marco and fill with clean water and with sanitizing fluid in
the concentration and contact time recommended by the manufacturer.
3. Disconnect the water connections and connect them to the sanitization cartridge.
4. Turn on water mains and power supply mains.
5.DO NOT TURN ON COMPRESSOR SWITCH AT THIS TIME
6. Flush all lines (Cold and Sparkling) with sanitizer, pressing the main dispensing buttons on the front control panel until you
can smell the sanitizing product which may have a characteristic smell, or colour. Colorimetric test strips can also be used to
make sure the entire line is filled with the sanitizing liquid.
7. Alternate the dispensing operations every 15 seconds, respecting the maximum product usage time recommended by the
manufacturer (failure to respect the exposure time may cause damage to the system).
8. NOTE: A container and drain basin will be required to collect water from the faucet.
9.Be careful: respect the sanitiser concentration and contact time recommended by the manufacturer; using extra liquid will
neither improve nor speed up the treatment process
.
5.1 CLEANING
The exterior of these machines may be cleaned with a damp cloth and a light detergent. Do not use abrasive cloths or creams, as
this will spoil the finish of the machine. Do not use a water jet or spray. Beware of accidentally operating the draw off tap or push
button when cleaning the front of the machine.
5.2 CAUTIONS AND SAFETY TIPS
•Risk of flooding. The hose supplied with this unit is non-toxic food quality tested to 190psi (1300 kPa). However, a hose is not a
permanent connection. It is, therefore, advisable to switch off chiller and close the stopcock valve when chiller is not in use, e.g.
overnight, weekends etc.
