•
Do not flush directly the inner parts of the blast chiller
because the electrical parts could get damaged.
•
Do not use any hard metal tools to remove the ice
.
•
For the cleaning use only warm water (not hot) with no-aggressive detergents, taking care of
drying the wet parts with a soft cloth.
•
Avoid to use products that contain chlorine or diluted solutions, caustic soda, abrasive detergents,
muriatic acid,
vinegar, bleach or other products that might scratch or grind.
•
We recommend to clean the device at least once a month,
when it used for deep-frozen products.
Attention, during the cleaning operations it is recommended to use work gloves.
3.2 CLEANING THE PROBE
The maintenance of the blast chiller must include at least one daily cleaning of the temperature core
probe.
It is essential to keep daily clean the blast chiller room probe. All the pro-
cedures must be carried out with the stationary unit removing the tension
from both the refrigerated item and the condensing unit. We recommend
to rinse carefully the probe with clean water and with hygienized solution.
Refer to the same methods and detergents for cleaning named in the pre-
vious paragraph.
3.3 CLEANING THE CONDENSER UNIT
All the cleaning operations must be carried out when the unit is off, taking off the electric tension from
both the device and the condensing unit. Only qualified staff shall carry out the cleaning operations.
For the cleaning and maintenance of the parts made of stainless steel, follow the below recommendations,
considering that the first and basic rule is to guarantee the no-toxicity and the maximum hygiene of the treated
products. The stainless steel has a fine layer of oxide that prevents the making of rust. There are detergents that
can destroy or corrode that layer, originating therefore corrosions.
Before using any detergents inquire with your family supplier about neutral products without chlorine, in order
to avoid corrosions of the steel. In case of scratches on the surface it is necessary to smooth it with the finest
stainless steel wool or with abrasive cloth made of sinewy synthetic material.
For the cleaning of the stainless steel it is recommended not to use steel wool and do not leave them on it
because little ferrous deposits might remain on the surface and therefore it could cause the making of rust and
compromise the hygiene conditions.
In order to have always a good function of the condensing unit it is necessary to carry out pe-
riodically the condenser cleaning. This cleaning depends mostly on the environment where the
condensing unit is installed.
It is advisable to use an air flush blowing from the inside to the outside of the unit. If it was not possible, use
a long bristle brush on the external of the condenser. Be careful not to damage the circuit of the cooling
fluid. The built in condensing unit is placed in the lower side of the blast chiller. Do not use water splashes.
Attention, during the cleaning operations it is recommended to use work gloves.
