II. ILLUSTRATIONS (Function Parameters)
1.F2（Return difference temperature）=set temperature-lower limit temperature.
Assuming that the temperature should be controlled between 20℃and 22℃,set
temperature as 22 ℃,the lower limit temperature as 20 ℃,then the return difference
temperature F2=2 ℃(default return difference as 2 ℃).
2.F1(Temperature error correction)=actual temperature-display temperature. When
display temperature and actual temperature are different, this parameter can be
corrected.
3.When temperature sensor meets ‘Measuring temperature=set temperature-return
difference temperature F2’,HEAT indicator is on which means an automatic
access to the heating device.when the temperature sensors meets ‘Measuring
temperature=set temperature’, HEAT indicator is off and THERMAL indicate
light is on which means the heating device is cut off.
4.Digital Measuring temperature=set temperature controller: It is on the control panel
and mainly in charge of controlling the heating Measuring temperature=set
temperature of the heat pipe to ensure the water Measuring temperature=set
temperature inside the tank.

III. IMPORTANT SAFEGUARDS
1.Make sure that your power supply matches with the power that marked on the
product. The deviation is under 10%.
2.Place the appliance on a level surface to prevent it from falling.
3.Keep it out of reach of kids and incompetent persons.
4.Never immerse it in water or any other liquid.
5.If it shows any signs of damage, have it repaired by a qualified electrician.
6.Remember to turn it off when it is not used.
IV. OPERATING INSTRUCTIONS
1. Put machine on a suitable place and check its conditions. Pull water into its tank
and make sure it is between maximum and minimum marks. Then checking
whether drain valve on the side is sealed up and exhaust valve is open.
2.Put stainless steel pots on water tank..
3.Connect machine to power and press switch to ON condition. Then machine’s
display is working. To get your desired temperature,press SET firstly,then adjust
related digital vie ▲and ▼switch.
4.Once temperature is set, heating tube start to work and HEAT indicator is on.
Thermostat will be cut automatically when temperature arrived to pre-set desired
temperature.At the same time HEAT indicator is off and THERMAL indicator is on.
When temperature lowers a little, thermostat will get through electricity
automatically, HEAT indicator is on and heating tube works again, and temperature
rises. It works in this way repeatedly in order to make sure temperature is certain in
a range.
Please DO NOT change the set parameters arbitrarily unless they fail to meet
your need and need to be re-adjust.Reset steps are followed:
①Press SET for more 6 seconds.When F1 display,it indicates to enter‘Temperature
error correction’,pressing ▲or ▼to adjust the temperature error.
F1=actual temperature-display temperature.
②Press SET to search F1& F2 key by scrolling and to select your desired adjustment
parameter. Press ▲and ▼key for parameter modification.
③The parameter setting operation can be exited automatically after about 8
seconds’ operation.
5.Usually 50-60 ℃is recommended (Raising or lowing heating temperature according

to chocolate’s type and room temperature’s differences ).After setting, heating process
is on (HEAT indicator is on).Shredding the chocolate cubes(shredding chocolate
speeds up melting)and put them into the pot.Stirring the chocolate with a spoon until
them have been completely melted. And then adjust temperature to 40 ℃to keep
chocolate warm enough.
! Turn off machine’s power if it is not in use for a long time,otherwise
temperature will destroy chocolate’s taste.
! Do not add water if chocolate in pot becomes too sticky.Try to add a little oil or
cocoa butter.
6.Please turn off the machine and cut the electric plug if you don’t use it..
V. CLEANING & STORING
1.Do cut off machine’s power supply and wait it cooling down before cleaning.
2.Do clean the pot and keep heating tube clean.
3.Wipe the appliance with soft cloth .Never with abrasive products.
4.Store it in a dry place away from corrosive substances.
VI.CIRCUIT DIAGRAM
VII. ORDINARY MALFUNCTION
Failure
Cause
Solution
Power is on,display are off
Power connect goes wrong
Check power connection and
fuse(12amps)
If HEAT indicator don’t go
off,heating temperature will
be keep rising and Thermal
will be out of control
1.Water in tank has been
below the minimum line.
2.There is no water in tank.
1.Add water to the tank.
2.Contact technical personnel
of after-sales service if
problem isn’t done.
Display shows ‘E1’
Temperature sensor is on or in
a short circuit
Check whether the probe is it
bad contact,failure,or in an
open state
