Sanitisation Guide – 818 Cs Water Cooler - Borg & Overstrom 818 Installation & Operation Manual

Sanitisation Guide – 818 CS Water Cooler
1. Turn off incoming mains water, briefly press dispense button(s) to release internal water pressure from the
machine and remove filter.
2. Add 100 ml of a proprietary sanitisation fluid to a clean and empty service filter cartridge/dosing device and
connect into machine. Always ensure to use a reputable branded sanitisation fluid for effective action.
Please note: We recommend using a 3% Hydrogen Peroxide concentration base sanitising fluid of reputable
manufacture to the appropriate dilution ratios as supplied with the product or typically 1:30 max. (Stronger
concentrations will require larger dilution rates).
Please remember that most sanitisation fluids (including ozone) contain an active caustic/alkaline agent.
Always use responsibly and with care remembering that due to its alkaline nature unnecessary
concentrated/prolonged contact with any materials, including metals, can cause damage. Always rinse all
contact surfaces after use with clean water.
3. Turn on incoming water, allow service cartridge/doser to fill and then draw off at least 1 litre of water, using the
cold button only, for the machine to ingest the solution. Leave solution for 10 minutes inside machine for
sanitisation to take effect. During this time thoroughly clean the machine externally. For this we recommend
the use of proprietary disposable sanitisation wipes. Pay particular attention to the dispense faucet and the push
button controls. Remember to include the drip tray. If a Waste Overflow System is fitted, this may benefit from
flushing through with a small amount of dilute sanitisation fluid.
4. After a satisfactory period of time, flush the machine with at least 10 litres of clean water to clear any trace of
the sanitisation fluid. Optionally use test strips to check.
5. Turn off water and remove the service filter/doser and fit a new filter of reputable quality and suited to the site
conditions. We recommend pre-flushing the new filter to reduce any risk of any loose media in the filter
entering the solenoid valves and possibly causing a malfunction. Retain the service cartridge/doser for reuse.
6. Turn on incoming water supply and carefully ensure the thorough sanitising of the outside of the machine is
completed. Reconnect power and reset any service/filter life monitors accordingly. Ensure any hot tank inlet is
reconnected and the tank is purged of air before switching heater on again.
ALWAYS ENSURE ANY RESIDUAL AIR HAS BEEN PURGED FROM BOTH COLD AND
SPARKLING SYSTEMS AND ALL IS OPERATIONAL BEFORE LEAVING.
