Chillers and shock chillers/freezers
PURPOSE OF USE
Chillers and shock chillers/freezers belong to a group of professional refrigerated
and refrigerating-freezing equipment. Depending on the type they are produced in two
variants:
Chillers and chillers/freezers are used by catering companies, restaurants,
bakeries, confectioneries, hospitals and similar outlets, where it is necessary to blast chill
or freeze food immediately after it is processed in high temperatures (cooking, baking,
frying etc.).
Blast Chillers and Chillers/Freezers are fitted with:
•forced air-circulation system ensuring uniform chilling in the chamber
•ecological refrigerant R 404A
•isolation made of energy-saving polyurethane boards 60mm in thickness
•self-closing door (chillers/freezers)
•automatic thawing system
•user-friendly controlling interface
•a probe enabling to monitor the temperature of chilled/ frozen dish (optional)
•automatic recognition of probe presence
•six independent working programs for chillers
➢soft chill without hold from +700C to +30C in 90 minutes
➢soft chill with hold in +30C
➢blast freeze without hold from +700C to +30C in 90 minutes
➢blast freeze with hold in +30C
➢hold function
➢cooler defrost
•six independent working programs for chillers/freezers
➢soft chill without hold from +700C to +30C in 90 minutes
➢blast chill with hold in +30C
➢soft chill and freezing with hold from +700C to +30C in 90 minutes
➢blast chill and freezing with hold in -180C
➢hold function
➢cooler defrost
•programs operate either by use of a probe placed in the product being chilled/frozen
or on time
•open door sound indicator
•end of cycle sound indicator
•real cycle duration time indicator
•surface warming preventing freezing on and hardening of the (chillers/freezer) door
gasket
•possibility to communicate with an external printer which records time and temperature
reached in a work cycle, date and time of its commencement and end as an
indispensable part of HACCP (optional).

Blast chillers or chillers/freezer is an important constituent of every kitchen. It gives
completely new possibilities of prolonging the freshness of food thanks to the use of a modern
technology of blast chilling/ freezing. This technology enables to prepare high quality products
sometimeinadvance.
It consists in chilling or freezing of a dish prepared in high temperature in
convection-steam type ovens. Food preserved in such a way can be stored up to
several days when chilled and up to several months when frozen, depending on a
particular production method. Chilling of a dish from +70OC to + 3OC takes 90 minutes,
and freezing to -18OC takes 270 minutes.
Advantages of blast chilling/freezing are as follows:
•long period of food evaporation process is eliminated
•dish distinctive taste and scent is kept
•multiplying of bacteria is stopped. Normally they multiply between + 5OC and + 65OC
•the top quality an safety is guaranteed to a client
Blast chilling/freezing technology enables to assure HACCP quality standards.
COOLING SYSTEM OPERATION
In the appliance there is a one-step compressing cooling circulation. The cooling
system is filled with an ecological refrigerant (R404A –the date on the data plate). The
element which expands is a thermostatic expansion valve.
INTERIOR TEMPERATURE REGULATION
The chamber sensor of the electronic temperature controller is placed on the
back casing of the cooler. The controller is programmed in such a way that the
appliance can reach temperature of the chamber and product in accordance with the
work program chosen. Information about controller operation and choice of a suitable
work program is presented in Appendix No 3a and 3b.
PREPARING THE START-UP
Prior to first commencement of the appliance a protective foil has to be removed.
The exterior and interior surfaces have to be washed with warm water and a
degreasing agent used for dishwashing.
Abrasives or other agents which can scratch the surface must not be
used. Do not use water jet to wash but a wet cloth only.
After washing and before connecting to power supply the appliance has to be left to
dry up.
The appliance should be kept away from heat source and should not be
exposed to sun rays.

Chillers and shock chillers/freezers
The appliance can be levelled by screwing or unscrewing the adjustable legs.
Precise levelling will prevent noisy work of the compressor.
With planning of placing the appliance, you should take into account the place
for free open the doors and eventual entering of trolley.
ELECTRIC TERMINAL
The appliance is designed for 230V 50Hz power supply and should be supplied
from a separate low voltage circuit secured by fuses not exceeding 16A.
The appliance is fitted with a protective PE cable.
Prior to change of the connector the flexible conductor has to be fitted with an
adequate terminal (Y-type terminal).
The appliance can be started only after the effectiveness of fire
precautions has been verified by measurements conducted in
accordance with the regulations in force.
After it is confirmed that the electrical system meets the above mentioned
requirements, the unit can be finally connected to power supply by placing the
connector in the plug-in socket.
The unit prepared according to the above guidelines is ready to operate.
Since the appliance could get out of plumb by radius bigger that 30
 ,
connecting of the appliance to power supply should be delayed by 3  4
hours. Otherwise the condensation unit can be damaged.
USE AND OPERATION
It is recommended to introduce occasional breaks in the appliance operation in
order to clean the interior and compressor condenser.
In order to perform the activities specified above you should disconnect the
appliance by using the power switch and taking the connecting plug out of the plug-in
socket.
In order to clean the unit condenser the front unit chamber night blind should be
removed.
The unit condenser should be cleaned at least once a month. A soft brush or
vacuum cleaner can be used in order to clean the unit condenser.
Water jet cannot be used to clean the appliance. The producer will not
assume responsibility for the damage of the condensation unit if the
cleanness of condenser has not been observed.
The appliance is equipped with a drawer-type tray placed under the condensation
unit to collect drips created during thawing process.

APPROPRIATE AND SAFE WORK REGULATIONS
In order to assure safe, long-term and failure-free operation of an appliance
the following rules should be observed:
•To instruct maintenance staff in the regulations concerning use of electrical
appliances, in safety at work regulations as well as in first aid procedures in
emergency situations
•To instruct maintenance in regulations concerning proper handling of an
appliance
•It is forbidden to connect an appliance to power supply, which has not been
properly checked as regards conformity to fire precautions.
•It is forbidden to connect an appliance to the plug-in socket not fitted with
neutralising plug
•It is forbidden to wash, clean or repair an appliance when it is connected to
power supply
•Any repair can be performed only by an authorised person and in line with
the rule saying that used/damaged parts can be replaced only with new and
identical ones
•The manufacturer declines all responsibility for all damages arising from
improper use of an appliance inconsistent with its purpose
•It is forbidden to draw night blind in the condensation unit chamber because
it can cause improper functioning of an appliance. The minimum space
between night blind and the condensing chamber should be 1 meter
•An appliance should be used in the environment where the temperature ranges
between 16 and 30ºC (in models DMP up to 25ºC), where relative humidity
does not exceed 60% and in dry and airy room
TRANSPORT
The manufacturer dispatches the appliances on pallets protected by cardboard
shapes and foil. The appliance should be protected in transport against shifting.
The appliances should be transported in work mode.
The manufacturer declines all responsibility for an appliance which
was damaged in transport.
