For correct cleaning of the evaporator:
Perform a defrost by leaving the door open.
Do not use pressurised water jets to wash the evapora-
tor coil as this operation could damage the aluminium
fins that make up the finned unit.
Do not use metal tools such as screwdrivers to remove
ice or accumulated residues, as they could damage the
protective surface layer or the evaporator coil piping.
Do not use solvents, thinners or preparations contain-
ing salts, acids or any other substance that can leave
residues that are harmful, toxic or hazardous for human
health.
Do not use aggressive products to clean the evaporator
coil (See the list of substances in paragraph: "ATMOS-
PHERES AND AGGRESSIVE SUBSTANCES INSIDE
THE CABINET.")
To access the evaporator, open the chilling cabinet door.
Then unlock the padlockable lever of the fan doors and
open them (figure 50).When cleaning is carried out on
the evaporator, pay particular attention to not bend the
aluminium fins and, if present, also pay attention to the
condenser of the sanitiser. The latter could be damaged
by impact.
WARNING!
Before carrying out any cleaning and maintenance
operation it is necessary to disconnect the blast chiller
from the mains power supply.
6.5.3 Maintenance and cleaning of the evaporator
Ioniser units require simple maintenance which consists
of periodic cleaning of the quartz condensers. Cleaning
is important because it guarantees the efficiency of the
devices and increases the life of the condensers.
Recommended maintenance frequency depends on the
chemical composition of the air and the quantity. Lack
of adequate maintenance of the device may result in
operational deterioration.
The frequency of cleaning depends on the usage: 1 to
3 months, depending on the quality of the air treated.
It is recommended to replace the condenser after
about 8,000 hours of continuous operation or when the
quartz appears extremely opaque. It is the customer's
responsibility to carry out all maintenance operations
on the device. If you find a malfunction, it is necessary
to disconnect the machine from the mains power and
seeks the assistance of specialised personnel.
