and use a silicon wax to protect the steel.

PERIODICALLY CLEANING THE CONDENSER

The condenser should be cleaned periodically. Cleaning intervals will depend on
how frequently it is used.

CAUTION

: To access the condenser (please refer to page 16 in the spare parts
catalogue) it is necessary to remove the safety guards. Always use qualified and
specialised personnel.
To guarantee efficiency and performance in time, it is necessary to clean the
condenser periodically. It is highly recommended if located in dusty environments to
clean the louvers on the refrigerating unit once a month and once every three months
if located in closed and clean environments. To remove dust and dirt from the
louvers use a brush or vacuum cleaner. Do not use sharp objects or tools that could
damage the condenser. Do not clean using water jets.

MEASURES TO TAKE WHEN OUT OF SERVICE FOR A PERIOD OF TIME

37

When the Chiller is out of service for a long period of time take the following
measures:

- Remove the plug from the power socket;

- Remove all food and clean the inside of the Chiller and all accessories;

- Buff all the stainless steel surfaces with a cloth moistened with vaseline oil
to give a protective coating;

- Leave the door ajar for air circulation to prevent bad odours;

- Periodically air the room or kitchen where the Chiller is installed.

EXTRAORDINARY MAINTENANCE

CAUTION: Extraordinary maintenance and servicing work must be carried out be

qualified personnel!

UNDERSTANDING SIMPLE MALFUNCTIONS

At times malfunctions are due to simple and trivial causes and nearly always there is
no need to call in a specialised technician, therefore before informing the company
check for the following:

The Chiller is not powered:

c. Check that it is plugged in;
d. Check that there is power.

The Chiller does not reach the correct internal temperature:

c. Check the temperature settings;
d. Check the probe.

The Chiller is excessively noisy:

c. Check that the Chiller is level. If unbalanced this could cause vibrations

creating excessive noise.

d. Check that the Chiller is not positioned up against other machines or objects

causing vibrations.

After having proceeded with the foregoing checks and if the problem persists,
contact the company giving:

- A description of the type of malfunction;

- Chiller code and serial number which are indicated on the metal plate.

WASTE DISPOSAL AND SCRAPPING

Storing waste:

It is possible to temporarily store special waste products that are to be scrapped.
However, the user must observe and adhere to the local governing laws regarding
waste management.

Macro – dismantling the Chiller:

Each country has its own waste management laws, therefore the user must observe
and adhere to the local governing laws where the Chiller is to be scrapped.
As a general guideline the Chiller should be handed over to a special waste treatment
plant. Dismantle it and divide the various components into groups according to their
chemical properties. Remember that there is oil and refrigerating solutions in the
condenser that can be recuperated and reused and the various components are
considered special waste products and as such are treated as urban waste.

CAUTION

: All dismantling operations must be carried out by specialised

personnel!

INSTALLATION INSTRUCTIONS

INTRODUCTION

This manual aims at providing the user with all the necessary information to
correctly use and maintain the Chiller.
Before use carefully read all the instructions given in this manual.
The manufacturer shall decline all responsibility for operations and use which
disregard the instructions herein.

MATERIALS AND CHILLING SOLUTIONS

All the surfaces that come in contact with food are in stainless steel.
This Chiller has an HFC chilling solution which is consented by current law. The
type and quality of the gas is indicated on the metal plate.

ELEMENTARY SAFETY STANDARDS – RISKS

39

The Chiller has no dangerous corners, sharp and cutting surfaces or protruding parts.
All safety guards on moving parts or electrics are screwed to the cabinet. These
guards avoid any form of accidental contact with parts that present a risk to the user.
Always respect safety standards:

- Do not touch the Chiller with wet hands or feet;

- Not use the Chiller barefooted;

- Do not poke screwdrivers, cutlery or other objects between the safety
guards mounted on moving parts;

- Before cleaning or servicing the Chiller lock-off the power supply.

INSTALLATION

Carefully follow and adhere to the instructions given in this chapter to guarantee
working efficiency and safety when the Chiller is in use.

CAUTION

: When transporting or moving the Chiller to the installation site do not

push or drag it, lift it and position it on a trolley to avoid overturning.

LOCATION

Locate the Chiller in a ventilated area distant from heat sources such as radiators, air
conditioning units, deep-fryers and ovens.
Make sure the Chiller is located at a distance not less than 10 cm from the back wall
to permit a good cooling effect for the various components.

To maintain the correct internal temperature, the ambient temperature must not
exceed +32°C

Adjust height and levelling using the support feet and also check the door closes. If
the Chiller is not perfectly level working efficiency and condensation flow may be
affected.
Remove the PVC protective film on both sides of the Chiller.

CONNECTING TO THE POWER SUPPLY

The Blast Chiller works off single-phase tension 230V- 50Hz.
To connect to the power supply, simply plug the power cable in the power socket or
connect the Chiller to the electrical panel, however before connecting check that:

40

- The socket is earthed and frequency and tension correspond to the
information given on the metal plate. If in doubt about earthing, call in a
qualified electrician to check wiring.

- A suitable thermomagnetic switch must be provided between the power
cable and electricity line with at least a 3 mm break contact.

- when the Chiller is connected to the mains check that the supply tension,
with the Chiller working, does not exceed or go under the rated tension by
+/- 10%.

CAUTION

: the manufacturer shall not be held responsible for damage or accidents
caused by negligence due to the non-observance of the recommendations and
regulations given or of the local governing standards and laws regarding electrical
safety.

RECOMMENDATIONS FOR CORRECT USE

Before using the Chiller remove all traces of glue using a detergent as there might be
traces of condensate due to final testing in the factory.
Chiller efficiency when chilling and freezing depends on the following factors:

Type of containers to use:

We recommend you use pans (or containers with sides no greater than 65 mm in
height) to permit an effective air circulation (the food product should be exposed to
the air circulation as much as possible to reduce chilling times ). To avoid the food
being contaminated, we recommend you carefully clean all containers and trays. We
also recommend you keep the food in the same cooking pan when chilling.

Using covers:

Do not cover the food when chilling or freezing. Only once the chilling and freezing
cycles have been completed or before storage can you cover or pack the food.

41

CYCLES

BLAST CHILLING

The blast chilling cycle rapidly lowers the temperature of the food to a minimum of
+3 °C.
Blast chilling is for food that will be consumed within a few days.

BLAST FREEZING

Blast freezing is for storing food for longer periods of time. When blast freezing the
water content in the food is micro crystallized so when defrosting the food is not
altered in any way maintaining both its appearance and nutritional value. When
freezing the food core temperature reaches –18°C.

STORAGE

The Chiller has a storage cycle, in other words it maintains a set temperature, which
is automatically activated when the chilling or freezing cycles have been completed.
This storage is continuous and to stop the program simply press the (ON-OFF)
button.

Due to Chiller consumption, we recommend that you do not use this Chiller for
storing food for a long period of time. We suggest you store the food in fridges or
freezers.
