MAINTENANCE

Important notice!!

Access to the machine interior for maintenance and/or
repairs is via the back panel.
Therefore, provisions must be made for the machine to be
rotated, thus allowing removal of the back panel.

The integrity of the vending machine and its conform-
ity with the rules and regulations in force for its
relevant systems must be checked by qualified per-
sonnel at least once a year.

Switch the machine off before any maintenance op-
erations which require removal of components.

The following operations must be carried out only by
personnel who have the specific knowledge of the
machine functioning from a point of view of electrical
safety and health regulations.

INTRODUCTION

To ensure perfect operation for a long period, the machine
must be subjected to regular maintenance.
The following sections contain the procedures and the
maintenance schedule, which are only a general indica-
tion, as they greatly depend on the operating conditions
(e.g. water hardness, environmental humidity and tem-
perature, type of product used, etc.).
The procedures described in this chapter are not exhaus-
tive of all maintenance operations to be carried out.
More complex operations (e.g. boiler descaling) should be
carried out by qualified technicians only having specific
knowledge of the machine.
To prevent oxidation or the action of chemical agents, the
stainless steel and varnished surfaces should be kept
clean by using mild detergents (solvents must not be
used).

Never use water jets to clean the machine.

MAINTENANCE OF THE BREWING UNIT

Every 10,000 selections or every 6 months some mainte-
nance of the coffee unit must be carried out.
Maintenance is carried out as follows:

- remove the boiler teflon hose connection from the upper

piston, paying attention not to lose the seal (see Fig. 17);

- undo the knob securing the unit to the bracket;

- remove the brewing unit.
