4.2 MAINTENANCE
Maintenance procedures (described below) are required for optimum equipment operation.
4.2.1 DAILY MAINTENANCE
1. The font. Clean the font nozzle and remove any residue using warm water; do not use solvents or abrasive detergents. If
required, remove any scale with a food descaling solution.
2. Drip tray. Clean the tray and remove any residue using warm water.
3. CO2 pressure. If using an external CO2 cylinder review the CO2 pressure gauges to ensure settings are correct.
4. Power cord. Check condition of the power cord. Replace if necessary.
4.2.2 LIMESCALE
Descaling of the machine should ideally be carried out by qualified service personnel.
4.2.3 CHECK FOR CO2 PRESSURE
Review pressure CO2 gauges to ensure the settings are correct, 50 - 65 psi (350 - 450 Kpi) (3-4.5 bar)
4.3 INSTALLING AN INTERNAL CO2 CYLINDER
Open the side door. Install the CO2 cylinder into the machine. Once the CO2 cylinder is installed, the yellow CO2 light stops flashing
on the font of the machine.
4.4 INSTALLING AN EXTERNAL CO2 CYLINDER
The cyclinder must be replaced when the needle of the reducer high pressure gauge is in the red segment or when the CO2 light
on the front of the chiller flashes.
1.Record the pressure values set on the pressure reducer, then fully close the bottle with the valve.
2.Remove the pressure reducer or disconnect the high pressure hose from the bottle if fitted. Check the condition of the gaskets
between the reducer and the bottle, replace them if necessary.
3.Replace the CO2 cylinder by slowly opening the valve to the fully open position and check that the pressure values are as
originally set.
4.5 CLEANING THE CHILLER CONDENSER
Check the chiller condenser every 6 months and in accordance to the environmental conditions (humidity and dust). If dust or
dirt occurs between the condenser blades clean the condenser fins using a soft brush, a vacuum cleaner or a low-pressure
compressed air. Remove any dust from the cooling and electrical components. Accumulation of dust and grease over the
condenser may cause overheating which could damage the compressor beyond repair. The condenser must always be cleaned
when necessary. Do not use wire brushes or compressed air jets as they can damage the condenser.
