6.OPER ATION OF FUNCTION KEY

 

Turn the power switch ON .Heating inditor lamp (wax pot and nozzle)is linghing .process value of wax pot temperature is displayed on the lef t-side display window, process value of nozzle temperature is displayed on right-side display window. Indictor lamp for heating nozzle(wax pot)will became of flashing,then tcmperature value of heating nozzle (wax pot)approach to setting temperature value. so that you can start wax injection.

1)    SETTING TEMPER ATURE

A)  Pressing (MAMU)button,then the indicator lamp of temperature(TEMP)will e flashed,at this time ,display of wax pot temperature(or nozzle)on display window will be changed from real temperature value to set temperatrue value,the temperature will be set by pressing▲or▼buton .Each pressing the ▲(▼)button once,display value will be increased(decreased).

B)  If setting large(small)value, display value will be changed fast by pressing ▲or▼button until 3 seconds.

C)  After setting temperature finishing over 6 seconds, display temperature will be changed from set value to real temperature value .

2)    SETTING TIME

1)    Pressing (MAMU) button, then lamp of TIME flashing .

2)    Display of vacuum time (wax pot time)ofleft –side (right-side )display will change from real time value to set value ,at this time by pressing▲or▼button of left-side (right-side).Setting time procedure in the same way as setting temperature.

3)    WAX INJECTION LF MANUAL

Pressing the (MAMU)key,Lamp of TEMP(TIME)is unlit and lamp of TIMECON is lighting ,wax injection procedure can be strated by foot switch controlling in manual operation mode,vacuum time is set refer to item6-2)l.injection time is controlled by foot switch.pressing(MAMU)key again once for return to auto operation mode .

4)WAX INJECTION OF MANUAL

By this preliminary melting. Wax in the wax pot is once heated to high temperature so that the whole of wax is thoroughly molten and then temperature is lowered and stabilized to working temperature.

①  setting preliminary melting of wax

pressing both the ▼key ofleft –side and (MAMU)key simultaneous on stand –by .Preliminary melting temperature is displayed on the left-side display window.

Preliminar melting time is displaye on the right-side display window.

They will be changed by pressing ▲or▼key of left-side (temperature)and ▲or▼key of right-side (time ).

Example:When the left-side display window (preliminary melting temperature)is set to 90.0 and the right-side display window (preliminary melting time )is set to P02 .Temperature is controlles as the below graph.

①  Starting preliminary melting

Pressing (MAMU)key again once,preliminary meilting wax is started.

Then wax pot temperature 90.0 flashes on the right-side window, work time P02 flashes on the right-side window.

When the set time has elapsed,flashing of temperature

(tiem )display stops.If you want to stop preliminary melting of wax,pressing (MAMU)key or turn off power switch.

ATTENTION:during preliminary melting of wax. Evacuation and wax injection do not work .

5)SETTING AND RELEASE DEIAY TIME OF HEATER

①set of heater delay time

Pressing both (MAMU)key and▲key of right-side simultaneously on stand-by.H10 (10hours delay time )is displayed in left-side window P02(Preliminarymelting time)is displayed in right-side window.delay time can be changed by pressing ▲▼key of left-side.Finally pressing (MAMU)key.timer of heater is started .At time .90.0(temperature)and H10(delay time )is shown on display window.

②  release of heater delay time

when you want to release timer of heater, pressing(MAMU)key again once. This function, it is possible to turn power OFF at the end of a day work and then wax in the wax pot is molten and the temp-erature is stabilized before starting, work the next morning, once preliminary melting has been set and the heater delay time is turned ON, preliminary heating and the heater delay time work together. Example: when the heater delay time is see to H10, preliminary melting temperature is set to 90.0, and preliminary melting time is set to P02, temperature is controlled as the below guaph.

6)SECESTING CELSIUS AND FAHRENHEIT

Pressing both (MAMU)key and ▼key ofleft-side simuitaneously then either Celsius or fanrenheit can be selected for temperature read out unit.

7)INTIALIZING SET VALUES

Pressing both the (MAMU)key and ▼key of right fide simultaneously.

The memory of the machine is reset to the below initial set values .

Vacuum time:2.0see

Injection time:2.0see

wax pot TEMP:75.0 degrees C/166·degreesF

nozzle TEMP:72.0 degrees C/166·degreesf

Temperature change:0.1 degrees C/1·degreesf

! CAUTION

After timer start work, do not cut off power supply, otherwise you had set the time invalid.

 

7.WAX INJECTING

 

1)CHECKING BEFORE OPERATION

①Turn on the power switch of the machine and external device.

②Turn the three-way valve located on the vertical position

③Turn air pressure regulator knob clockwise slowly to increase air pressure.

! CAUTION

Check that on air-leak is found. When pressure gauge indication changes, check each connecting part of hoses.

① Indicator lamp for heating nozzle (wax pot)will be became of flashing, then temperature value of heating nozzle (wax pot)Approach to seting temperature value.

② Wait for one or two hours (waiting time depends on room temperature)until wax inside will be melted thoroughly. Then. you can start, wax injection.

! CAUTION

Determing optimum vacuum time and injection time depends on practice and experience of operator.

③  Before staring operation, it′s recommended to let the machine run in the Auto mode and test it several times for checking functions of each unit .
