IMPORTANT SAFETY INSTRUCTIONS, READ CAREFULLY
AND KEEP FOR FUTURE REFERENCE
INSTALLATION
IMPORTANT!!! PLEASE READ BEFORE INSTALLATION
■If the unit has recently been transported. Please let unit stand still for a minimum of 24 hours
before plugging it in.
■Make sure that there is proper ventilation around the unit in the where it will operate.
■Make sure all accessories are installed before plugging the unit in.
■Please read through the manual in its entirety.
■Disposal of old equipment should be done responsibly as per WEEE regulations and local
authority directives.
CABINET LOCATION AND INSTALLATION GUIDELINES
■Unpacking
The unit is delivered on a pallet and shrink-wrapped. Documentation is inserted into a clear
pocket located inside the unit. Carefully remove the protective plastic film and cardboard from
the unit exterior and from the door opening surround making sure that any sharp instrument
used does not cause damage, plus remove any quality labels.
■Install the unit on strong and leveled surfaces
－unit may make unpleasant noises if surface is uneven
－unit may malfunction if surface is uneven
－If the floor is not flat, please use something to make sure the base of this unit in horizontal
level
■Install the unit in an indoor, well-ventilated area
－unit performs more efficiently in a well-ventilated area Ensure the maximum design ambient
temperature is not exceeded
－for best performance, please maintain clearance of 100mm / 4”on the back of the unit,
50mm / 2”on the top of the unit.

2
－outdoor use may cause decrease efficiency and damage to the unit
■Avoid installation in a high humidity and/or dusty area
－humidity could cause unit to rust and decrease efficiency of the unit
－dust collected on condenser coil will cause unit to malfunction. Clean the condenser at least
once a month with a brush or clean cloth
■Select a location away from heat and moisture-generating equipment
－high ambient temperature will cause the compressor to overwork, leading to higher energy
bills and gradual breakdown of the unit
■The appliance shall not be exposed to rain, sun
The cabinet must not be located in a chloride /
acid-containing environment (swimming-bath etc.) due to
risk of corrosion.
CAUTION: PROBLEMS CAUSED BY UNPROPER
POSITION OF UNITS ARE NOT COVERED BY
WARRANTY
■The castor is with a brake, turn it to different side can lock or unlock the castor
ELECTRICAL SAFETY
■Please ensure that the required voltage of the compressor is being supplied at all times

3
CAUTION: Low or high voltage can detrimentally affect the refrigeration unit.
■All units should be plugged into a grounded and properly-sized electrical outlet with
appropriate overcurrent protection. Please refer to the electrical requirement on the
nameplate. If you do not have the right outlet have a certified electrician
install the correct power source.
To minimize shock and fire hazards, be sure not to overload outlet.
Please designate one outlet for your unit., make sure that the unit is properly
grounded.
■Please make sure that your unit has its own dedicated outlet. Do not use an extension
cord.
■When the unit is not in use for a long period of time, please unplug the unit from the
outlet.
■After unplugging the unit, wait at least 10 minutes before re-plugging it. Failure to do so
could cause damage to the compressor.
■Do not attempt to alter or tamper with the electrical cord.
OPERATION
GENERAL USE OF THE CABINET
Blast chiller & freezer quickly reduce the core temperature of the products, whether they are
cooked or fresh, conserving their fresh texture, hygiene and quality, whilst reducing the risk of
bacteria generating.
The traditional method of storing cooked food has always been to leave it to cool naturally until it
reaches a suitable temperature to store in the refrigerator.
During the period when the core temperature falls from +65ºC and +10ºC, the food will lose a lot
of its natural characteristics, such as moisture, consistency, aroma and color. These blast chillers

4
& freezers are designed to reduce the time period for this critical change in temperature.
■The storage cabinet is designed to fit two kinds of pans
* GN 1/1 pan
* 400x600 EN pan
When blast chilling always use metal or foil containers which
are good conductors. Plastic or polyurethane containers
insulate the food from the cold air. When chilling unportioned
food we recommend the use of the appropriate gastronorm
tray or similar, depth of tray to be max of 50mm.
■Loading food
Attention ： Make sure that the unit drops down to desired temperature before loading the
unit with food DO NOT overload the cabinet observe the max product weight.
-The maximum temperature of food entering the Blast Chiller/Blast Freezer must not exceed
+80°C (176°F). Regulations state that product should be placed in the Blast Chiller/Blast
Freezer within 30 minutes from completion of cooking.
-The packaging of food and the way in which it is loaded or placed within the equipment can
have a significant effect on the time within which the temperature can be reduced to the
require level and the amount of food which can be processed in each chilling or freezing
batch. (Maximum food thickness 50mm).
■It is important to insert the probe correctly.
The needle of probe should be inserted until the point reaches the
center of the foodstuff.
OPERATION INSTRUCTION FOR TEMPERATURE CONTROLLER
The unit 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.

5
• Any cycle can be manually terminated before the normal.
• Any cycle can use the insert probes (up to 3), they measure 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 the user.
• Each instrument is provided with an output for remote display XR REP, which shows the
temperature of cabinets or goods.
• The controller is provided with internal real time clock and can be connected to the 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.
