2. Clean the appliance and surrounding areas thoroughly.
3. Spread a thin layer of cooking oil onto the stainless steel surfaces
4. Carry out all maintenance operations
5. Leave the door ajar to prevent the formation of mould and / or unpleasant odour.
Do not insert foodstu󰀨s that are above the temperature of 90 °C.
Do not stack the materials to be preserved in contact with the internal walls so blocking the circulation
of air.
There must be a su󰀩cient space between the trays used in order to guarantee a su󰀩cient ow of
cold air on the entire product.
Never obstruct the inlet of the evaporator fans.
Products that are more di󰀩cult to chill because of their size should be placed in the centre.
Limit the number of times and the duration of time the door are opened.
After blast chilling/shock freezing the product, it can be stored in a preservation cabinet after having
been duly protected .A tag should be applied describing the contents of the product, blast chilling/
shock freezing date and expiry date. When the product has been blast chilled it must be preserved at
a constant temperature of +2 °C while if it has been shock frozen it must be preserved at a constant
temperature of -20 °C.
The chiller should be used for storage for short periods only.
To prevent bacterial contamination or contamination of any other biological
nature, the needle probe must be disinfected after use.

BLAST CHILLING CYCLE
7
With this operating modality the chiller keeps the temperature of the refrigerating compartment close
to zero during the entire chilling process in order to ensure a gradual drop in the temperature of the
product to +3 °C.In this way, ice crystals do not form on the surface of the product .This blast chilling
method should be used preferably for products that are not packed and whose physical/organoleptic
characteristics could be damaged by the formation of supercial ice (e.g. sh)
SHOCK FREEZING CYCLE
With this blast chilling modality the blast chiller maintains the temperature at a negative value below
-18 °C which is the end temperature of shock freezing .For shock freezing to be successful and fast,
food should be in small pieces, especially if it has a high fat content. The largest pieces should be
placed in central trays .If it takes longer than standard time to shock freeze and the sizes cannot
be reduced, decrease the quantity and precool the chiller compartment by starting an empty shock
freezing cycle before shock freezing the product.
CLEANING AND MAINTENANCE
Switch o󰀨 the electrical connection at the socket.
The cabinet must be periodically cleaned. Clean the external and internal surfaces of the cabinet with
a light soap solution and subsequently wipe dry. External surfaces can be maintained using steel oil.
Do not spray the appliance with direct jets of water or using high pressure appliances.
Do not use iron wool. brushes or scrapers to clean the stainless steel as ferrous particles could be
deposited which ,on oxidizing, could lead to rust.
To remove hardened residues, use wooden or plastic spatulas or abrasive rubber pads.
Clean the condenser
Clean the condenser periodically.
As the ns of the condenser are very sharp, always wear protective gloves for the next phases.
Use protective masks and glasses in the presence of dust.
Whenever the condenser has a deposit of dust in correspondence with the ns, this can be
removed using a suction device or with a brush applied, using a vertical movement along the
direction of the ns.
No other instruments must be used, which may deform the ns and therefore the e󰀩ciency of the
appliance.

To clean, proceed as follows:
1. Open the door (A) of the appliances.
2. Remove the lower panel(B) from the technical compartment: to do this, remove the screw
fasteners(C)
3. It is now possible to clean the nned part of the condenser (D) using suitable tools and
protection devices.
4. After cleaning, close the control panel and x it with the screws removed beforehand.
SERVICE
The cooling system is a hermetically sealed system and does not require supervision, only cleaning.
If the cabinet fails to cool, check if the reason is a power cut.
If you cannot locate the reason to the failure of the cabinet, please contact your supplier. Please
inform model and serial number of the cabinet. You can nd this information on the rating label which
is placed inside the cabinet in the top right hand side.
DISPOSAL
Disposal of the cabinet must take place in an environmentally correct way. Please note existing
regulation on disposal. There may be special requirements and conditions which must be observed.

• Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden
temperature changes with high atmospheric humidity to prevent formation ofcondensation
• Warning: disconnect all electrical connections before any kind of maintenance.
• Fit the probe where it is not accessible by the End User. The instrument must not beopened.
• In case of failure or faulty operation send the instrument back to the distributor or to “Dixell S.r.l.” (see
address) with a detailed description of the fault.
• Consider the maximum current which can be applied to each relay (see Technical Data).
• Ensure that the wires for probes, loads and the power supply are separated and far enough from each
other, without crossing or intertwining.
• In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with
inductive loads could be useful.
3. GENERAL FEATURES
The series XB has been created for fast chilling or freezing goods according to international food safety
standards.
There are FOUR types of cycles:
• The CYCLES: Cy1, Cy2, Cy3, Cy4 are pre-set according to the most common cycles used in food -
safety applications; the user can select one of them according to his own requirements and modify it as
he wants.
• Any cycle can be manually terminated before the normal.
• Any cycle can use the insert probes (up to 3), they measures the internal temperature of the product.
• During the Cycle there are no defrosts and the fans are always on, a defrost cycle can be done before
any freezing cycle.
• The cycle is divided up to 3 phases completely configurable by theuser.

1592006207 XB570L GB r1.1 26.08.2015
XB570L
4 /20
• Each instrument is provided with an output for remote display XR REP, which shows the temperature of
cabinets or goods.
• The XB570L controller is provided with internal real time clock and can be connected to the XB07PR
printer. This means that a report, which includes all the main features of cycle, can be printed: start and
end of the cycle, length of the cycle, logging of the temperature of the cabinet and goods.
4. MOUNTING & INSTALLATION
Model XB570L is a controller for panel mounting: the cut out dimensions are 150x31 mm and it has to be
fixed with screws. The ambient operating temperature range is from 0.0 to 60°C. Avoid locations subject to
heavy vibration, corrosive gases or excessive dirt. The same warnings have to be applied to the probes.
Ensure enought ventilation around the instrument.
5. ELECTRICAL CONNECTIONS
The instruments are provided with a screw terminal block to connect cables with a cross section up to
2.5mm2 for probes and digital input.
Spade on 6.3 mm heat-resistant wiring for supply and loads. Before connecting cables make sure the power
supply complies with the instrument’s requirements. Separate the input connection cables from the power
supply cables, from the outputs and the power connections. Do not exceed the maximum current allowed
on each relay, in case of heavier loads, a suitable external relay has to be used.
The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. It is
recommended to place the thermostat probe away from air streams to correctly measure the average room
temperature. Place the defrost termination probe among the evaporator fins in the coldest place, where most
ice is formed, far from heaters and from the warmest place during defrost, to prevent premature defrost
termination.
