8. MAINTENANCE
ALWAYS UNPLUG THE ELECTRICITY when carrying out maintenance checks or operations.
8.A. INSTRUCTIONS FOR DRAINING WATER FROM THE BOILER
Attention: For machines with a small capacity boiler (less than 5 litres) it is recommended
Pict.1
to change the water frequently. Remove one litre of water every day, taking it from the hot
water tap.
Fit the rubber tube (long enough to reach the bar counter drain) to the union located under
the boiler (Pict.1). Unscrew the union by two turns only and wait until the boiler is com-
pletely empty. Then screw the union back up again.
Pict.2
Model with drain tray and tap (Pict.2)
Open the tap located under the boiler and wait until the boiler is completely empty. Then
close the tap again.
8.B. INSTRUCTIONS FOR REGENERATING THE SOFTENER
The instructions given below should be followed to regenerate the softener:
1) Put a container with a capacity of at least 2 litres under pipe E. Move levers C and D from left to right.
2) Remove the lid by unscrewing knob G and put salt (normal kitchen salt) into the softener (pict.1): 1 kg. for the 8-litre softener and 2
kg. for the 12-litre softener. Then refit lid and move tap lever C from right to left (pict.2) so that the salty water can flow through pipe F.
When the water is pure, reset lever D from right to left (pict.3).
Important:
Regeneration must be done every 15 days for a daily coffee consumption of between 1 and 2 kg. If consumption is greater than this,
regeneration should be done every 7 days.
Attention:
It is very important to regenerate the softener. Failure to regenerate the resins in the softener causes calcification in the boiler, the so-
lenoid valves and the hydraulic circuit. These deposits have a negative influence on the machine's performance and reliability and can
even cause serious damage, which will lead to the intervention of the assistance service for cleaning the boiler. This type of interven-
tion is not covered by guarantee and therefore the relative costs are the responsibility of the owner of the machine.
