1.3. Dangers while operating the furnace
The furnace was designed and constructed according to the newest technological
and security standards.
The achine can be used only when its technical condition is perfect. The usage of the
device which is at variance with its purpose leads to the considerable risk of threatening
the lives of people operating the achine, and also of the da age to the achine as well
as the anufactured products.
Disruptions which have negative influence on the safety of the achine operation ust
be re oved i ediately. The achine cannot be used until all erros are re oved.
1.4. Organizational measures
Protective equip ent for the staff ust be provided by the purchaser. All security
devices ust be checked before the achine is in use.
The furnace must operate under the fully operational travelator which is
connected to the unobstructed chimney flue, far away from any flammable
materials
1.5. Industrial safety devices
Before each start of the achine install the following devices and check their
function:
- ain switch that can be closed, which ensures that unauthorized people will not turn
the achine on;
- safety lids.

1.6. Removal of safety devices
Safety devices can be re oved only when the ain power generator is
disconnected.
1.7. Security measures
The instruction anual should be put in a visible place, in the vicinity of the
furnace. In addition, general and specific rules connected with accident prevention and
environ ent preservation ust be provided.
All signs which can be found on the achine should be legible.
1.8. Operating the machine
Only trained staff can use the achine.
Specify who is responsible for:
- operation
- turning on
- preparation of the achine
- aintenance and repair of the achine
Apprentices can operate the machine only under the supervision of a trained
worker
1.9. Security measures while normal machine operation
The furnace can be used only when all security devices work properly. At least one
ti e a day the achine should be checked in case of any da ages.
The furnace should be equipped with the etal pliers with insulated handle and
te perature resistant protective gloves.
The roo where the furnace is in operation should be equipped with the first-aid kit
containing phar aceutical preparations used in treating burns and fire extinguisher for
electric appliances.
1.10. Dangers connected with the presence of electric energy
- all works concerning electric devices and achine power supply can be done only by an
authorized electrician engineer;
- the side lids should be always closed. Only authorized experts can work with opened
lids;
- all loose connections and da aged lines ust be i ediately replaced. Do not use the
achine before the replace ent;
- all works while the devices are turned on can be done only when it is necessary.
1.11. Structural changes in the machine
The furnace cannot be enlarged or odified without the authorization of the
anufacturer. The written authorization is necessary to perfor any odifications of the
achine.
Faulty parts ust be i ediately replaced.
Only original spare parts can be used. The anufacturer does not take the guarantee
into consideration if the spare parts used are not original.
1.12. Activities of special attention
Staying in the vicinity of the working furnace, especially while its door is opened,
requires particular caution on account of high te perature inside the furnace cha ber.

1.14. Guarantee
Argenta co pany cannot aintain the service warranty or be responsible for
people’s injuries or any da age of the achine when they are caused by the following
factors:
- i proper usage of the achine
- i proper asse bly, settings, operation or aintenance of the achine
- operating the achine in which there are so e da aged and/or not working security
devices
- disregarding the instruction anual
- unauthorized structural changes in the achine
- insufficient inspection of worn out parts
- natural disasters.
1.15. Responsibilities
Only the factory anager, whose plant the achine was installed in, is
responsible for the safety of workers.

2. Intended use of the furnace
The furnace is intended for heating and drying trays ( etal oulds) which are
applied in the process of jewellery casting with the use of stay-in-place wax ethod.
The construction and technical para eters of the furnace enable to use it for all casting
ass which are available on the arket.
The application of te perature progra selector enables the control of the heating
process with the priority of te perature over the ti e. It is possible to progra e two
independent progra s with sixteen sections in each one.
3. Furnace design – general comments
The furnace is constructed of two joined units which constitute one entity. The
first unit is a furnace which consists of a steel (or stainless steel – depending on the
order) construction, a heat insulation layer (40 ) on each wall of the cha ber, electric
and resistance heaters and a ther ocouple which is placed in the heating cha ber. The
second unit is a te perature progra selector with the se iconductor joining ele ent.

Fig.1. Reference drawing of the furnace
The furnace is equipped with the set of heatproof cera ic tiles which constitute the
panelling of the furnace ground. Its purpose is to protect the heatproof fibre fro
da age.
WARNING: Provided socket may resemble a three-phase socket, but its application and
connection is completely different.
WARNING: Using metal trays as the furnace floor protection is impermissible. It cannot
be allowed to let wax remnants cover the furnace floor.
WARNING: he furnace structure allows the wax to soak into the bottom part of the
furnace chamber.
WARNING: Cooling down the furnace chamber with the use of fans or other appliances
extorting air circulation is impermissible.
WARNING: Burnt out trays should be previously dried in the drier in order to remove
the casting wax.

5. Electric connection of the furnace
The furnace connection can be performed only by a qualified electrician and only with
the application of all security measures. The furnace is powered with the use of a three-wire
power grid with a single-phase current. The machine is equipped with a reinforced, single-
phase plug and a suitable socket.

6. First launching
If it is the first launching of the furnace it is advisable to dry the heating chamber. To
perform this action a short programme should be set on the program selector (the first
section). It covers heating with the maximum temperature increase up to 700
o
C. After the
te perature is reached, the furnace can be turned off. This function should be initiated
only in the target operating area of the furnace, with the activated travelator. During the
first heating the insulating ats of the furnace will change their colour, which indicates
that the drying process proceeds in a correct way.

7. Temperature program selector
Te perature progra selector, which is also called a driver, is a unit of two
cooperating odules – a te perature adjuster and an electronic clock. The ain feature
which distinguishes it fro an ordinary te perature adjuster is a function of te perature
increase control in a specific ti e.

10. Warehousing and transport
•each furnace is equipped with the present Operation and
Maintenance Manual which confir s its origin by the serial nu ber
given by the anufacturer;
•during transport or warehousing the furnace should be wrapped in
foil and protected fro hu idity or da age;
•during the ti e of transportation the furnace should be wrapped in a
factory cardboard container which assures a proper protection –
transport on the pallet is advisable.
