Possible Occurrences During Operation; Ordinary Maintenance; Extraordinary Maintenance And Repairs - Tecno-gaz Unika Mode D'emploi

POSSIBLE OCCURRENCES DURING OPERATION

The operation of the machine is very simple; therefore cases of malfunction are very rare.
When the machine is switched on by means of the main switch, and the latter does not light up, this means that no
electric power is supplied; if the supply plug is inserted correctly, this is due to the fuses (see picture B pos. 6): they
need to be replaced and, if they burn again, contact the technical service.
When the switch is lit and the fans do not start operating after having set the timer, this means that they have been
damaged or that the timer is out of order; switch off the machine and contact the technical service.
When the machine is operating, if the discharge air is cold, this means that the resistances have been cut out; in this
case the objects can still be dried but several cycles must be repeated.
In some cases it can happen that the machine temperature increases due to high room temperature (ex. during
summertime), or to long use, or to difficult air circulation in small places. In such cases the heating elements can be
automatically switched off by the thermostat to avoid overheating, the produced air will be then cold.
Since the thermostat will automatic reset after machine has cooled down, it is enough to wait a few minutes in order to
start working again.
Another situation that may obtain is that the machine does not switch off automatically; in this case the timer is out of
order and the technical assistance must also be contacted.
Repairs must be carried out by TECNO-GAZ or by authorised personnel.
Unauthorised operations are considered as tampering and automatically entail the annulment of the warranty and
TECNO-GAZ does not shoulder any responsibility for damage following such unauthorised operations.
Ordinary maintenance consists in normal cleaning operations to be carried out when necessary according to the state
of the machine.
Before starting cleaning, the mains lead must be disconnected from the electric supply network.
To clean the tray and the drying chamber, bear in mind that the accumulated dirt is calcareous and therefore calls for
passing a sponge soaked with scale remover on the surface, waiting for the limestone to be removed, rinsing with the
sponge and finally drying.
The external surface can be simply cleaned by means of a moist cloth; no abrasive agent must be used.
Do not flood the machine, nor use water jets; the electrical and mechanic components would be damaged and the
operator may be involved in electric shock hazards.

EXTRAORDINARY MAINTENANCE AND REPAIRS

UNIKA does not require any extraordinary or periodical maintenance; it contains no components requiring greasing,
nor seals subject to wear.
The electric resistances do not need any maintenance either, unless they are damaged following specific events.
