Operation; Maintenance; Cleaning The Filter Of Water Supply Solenoid Valve; Air-Cooled Models - NTF SLF320 Instrucciones Y Advertencias

To obtain a faster and more efficient reply when you call the Center, state the model of the appliance
precisely, together with its serial number or manufacturing number. This information is given on the
serial N° plate (Fig. 1) affixed to the rear of the appliance and on the cover of this Instruction Manual.
The appliance has a thermostat probe in the ice bin, which stops ice production when the ice
accumulated in the bin reaches the probe connected to the thermostat.
When ice is taken from the bin, the thermostat will automatically reactivate ice production, thus creating
a new supply of ice.
9.1 CLEANING THE FILTER OF WATER SUPPLY SOLENOID VALVE (Fig.7)
!!
At least every two months, clean the filter (14) located on the water inlet solenoid valve, proceeding
as follows:
• switch off the electric power supply by means of the switch (7 in Fig. 5), fitted during installation,
and disconnect the plug of the appliance from its socket
• shut off the water supply by turning the tap (8 in Fig. 5) fitted during installation
• disconnect the water supply pipe from solenoid valve (11) at the back of the appliance
• using a pair of pliers, remove the filter (14) from its seat without damaging the water feed pipe
connector
• remove any residues by placing the filter under a jet of water; if it is too dirty, replace it with a new filter
identical to the one removed
After having carried out the cleaning operations, refit the filter and hose pipe
When the operations have terminated, turn on both the electricity supply and water supply.
9.2 AIR-COOLED MODELS (Fig. 8)
For air-cooled models, it is very important to keep the finned condenser and its external filter clean.
Have the finned condenser cleaned at least every 2 months by an Authorized Service Center, which can
include the operation in maintenance programs.
The external filter must be cleaned at least once a month, as follows:
• switch off appliance and cut off power supply with the switch (7 in Fig. 5) fitted at the installation
stage
• open plastic grille
• remove filter and keep it at a distance form the appliance
• remove dust from filter by blowing with compressed air
• replace filter in its seat and close plastic grille

9.3 CLEANING AND SANITIZING OPERATIONS

The frequency of cleaning and sanitizing operations can vary, depending on:
• temperature and environmental conditions
• temperature and quality of water (hardness, presence of grit, etc.)
• quantity of ice produced, or time of use of ice maker
• periods of non-use of ice maker
‼
IMPORTANT:
• we recommend that the operations described in this chapter should be performed by qualified,
authorized personnel.
• do not use corrosive substances to remove limestone from the appliance, because this will invalidate
the guarantee, and may cause serious damage to the materials and components of the appliance
• gloves suitable to protect against cuts must be worn when performing all operations involving handling
of sheet metal parts in particular
• gloves suitable to protect the skin against the substances used must be worn when performing all
cleaning and sanitizing operations
