USER ManUalFurnace eVO

Dear user, Thank you very much for choosing a KOTA product.KOTA produce equipment with high quality materials seeking to guarantee the confidence and safety of its products.To maintain the perfect functioning of your EVO Oven, some basic care is necessary. Read this manual carefully and follow the instructions for installation and use.

Safety precautions

• Use original KOTA products identified by the brand, which guarantee the best performance for your equipment.

• Do not modify the equipment or request third parties to do so, except when specifically KOTA authorize it, as performance and / or security could be compromised. Any alteration of the product without previous authorization will imply the loss of the guarantee.

• Do not use extensions or any type of connector between the power cord of the appliance and the socket. Procedures such as these could decrease the performance of your equipment and increase your energy consumption.

• For cleaning, use only a damp cloth. Do not apply abrasive, solvent or corrosive products on the equipment.

Safety precautions

• Do not place work removed from the oven directly on the glass at the base of the work area. Coatings or porcelain freshly removed from the equipment can cause cracks in the glass base. Maximum temperature over the glass: 200ºC.

• When turn on the equipment, place the refractory base on the aluminium tray. If do not perform this procedure so the rubber seal ring could be damaged.

• 3º: Connect the Vacuum Pump power cable to electrical connector located on the back of the unit as shown in the illustration on page 3. Check the main voltage. The Vacuum Pump voltage must be the same as that of the oven.

• 4º: Turn on the Main Switch of the EVO that is located on the right side of the oven as shown in the illustration on page 4. When the EVO is turn on the LCD will show the initial screen, as shown below:

Press “EDIT “to set the language selection.

• The languages Portuguese, English and Spanish are available.To return to the “TYPE OF PROGRAM” MENU, press the “EDIT” key.

STanD-by MoDE

The Stand-by mode serves to prevent peripheral heating of the oven and to save energy.Whenever the oven remains unused for more than five minutes, the muffle will close. To open the muffle press the “EXECUTE” key.

• Do not place work removed from the oven directly on the glass at the base of the work area. Coatings or porcelain freshly removed from the equipment can cause cracks in the glass base. Maximum temperature over the glass: 200ºC.

• When Turn On the equipment, place the refractory base on the aluminium tray. If do not perform this procedure so the rubber seal ring could be damaged

Selecting and editing a firing program

When selecting the firing program the following information will be on the screen:

On this screen, it is possible to move the lift up, down and stop in any position manually. Just press the left directional arrow to perform the two functions.The firing programs range from number 1 to 80.There are 33 firing programs inserted by the manufacturer that go from number 1 to 33.Those programs can be modified according to the instructions detailed below:

To edit a firing program, select a program number, and then press, “EDIT”.When press the “EDIT”key screens will be appear in the following order:

InITIaL TEMPEraTurE (TP1)

The initial temperature is the initial temperature of the firing process.

Inicial temperature

Number of the program selected

8

DryInG TIME (TSEc)

The drying time is the waiting period to the start of the closing stage of the muffle.

rISE TIME (TSub)

The closing time of the muffle can be adjusted to close directly or for a specific time between 00:40 seconds and 30:00 minutes.To activate the direct closing adjust the parameters in 00:00

PrE-FIrInG TIME (TPrE)

The PRE-FIRING time starts when the rise time reached 90% of the course.The elevator remains in the position by the programmed time and then the muffle will close.

9

DoWnInG TIME (TDES)

The downing time is activated after the last firing process be executed and can be adjusted for direct opening or for a determined time between 00:40 seconds and 30:00 minutes.To activate the direct opening, set the parameters to 00:00.

baSE TEMPEraTurE (TP2)

It is the next temperature level after the initial temperature.

HEaTInG raTE (Tr2)

It is the heating rate between the initial temperature and the base temperature 2.The parameters can be adjusted from 20 ° to 120°C per minute.

10

Setting up press mode

Follow the instructions for preparing the pressing mode according to the following description:

1 - Place the refractory base in the centre of the oven plate, according to the illustration on page 4.2 - Position the ring with the plunger and the pads on the centre of the plate refractory.3 - After pressing, “execute”, the oven will start the pressing program. The lift will immediately rise with the ring for the muffle, keeping the ring heated, and then run the program according to the parameters saved in the selected program.

IMPorTanT carE In THE oPEraTIon:The height of the assembly composed of the ring, the piston and the ceramic pads should not exceed 85mm. Failure to observe this point will prevent the complete closure of the muffle, damaging the elevator system.Use good quality coatings and follow the application instructions of each manufacturer regarding issues such as:

• Diameter of the sprue.• Correct angle for better material run off.• Distance of 10mm between the waxing and the wall of the ring avoiding breaks in the lining wall.• Base temperature and time of the melting furnaces.• Transfer of the melting furnace ring for the pressing furnace.• Follow the temperature guidelines and bases of the manufacturers of each tablet for the 100 and 200-gram rings.

After finishing the base time, the oven will execute the pressing automatically and later the program will end.
