13.5 PROCEDURE FOR DRAINING AIR-BREAK AND BOILER WATER (SERVICE 16 AND 17)
This section is for qualified assistance staff only.
These operations, which concern safety and hygiene, must be carried out by personnel
having practical experience with this machine.
The purpose for draining the water from the boiler is mainly to prepare the vending machine for safe
transportation or storage. In fact, the water is eliminated to prevent the risk of it spilling onto the electrical
parts and the risk of the boiler freezing.
The procedure is as follows:
1. Open the door and insert the key in the safety lock.
2. Access the programming mode.
3. Enter the number “52” to access the services mode and press ENTER.
4. Enter the number “16” to start the air-break emptying procedure and press ENTER.
At this point the water delivery to the air-break and the heating element of the boiler are automatically
disabled.
A coffee unit washing cycle begins: the purpose of this cycle is to empty the air-break and cool the boiler.
5. Rotate the frame by 180° as indicated in the paragraph “ACCESS TO THE INTERNAL COMPONENTS”.
6. Caution: the external temperature of the boiler could be very high. Burn hazard!
7. Disconnect the water delivery fitting located at the bottom of the boiler.
8. Replace the tube on the union with a plastic tube and prepare a container to collect the water from the
boiler.
9. Enter the number “17” to start the boiler emptying procedure and press ENTER.
Nota bene
Beware of the electrical parts near the boiler. Place the container for the collection of the water away from
the electrical parts.
• Remove the vending machine ignition key. Remove the tube applied to the coupling of the espresso
boiler. Clean and dry the vending machine of any traces of water which may have formed during the
procedure. Close the espresso unit support panel. Close the machine.
• At the end of the operation cut off the connection of the supply connector of the boiler heating element
(see paragraph FILLING UP THE HYDRAULIC CIRCUIT);
If necessary, restart the appliance following the instructions given in the “PLACING INTO SERVICE” section.
