Ⅲ、Working Condition
As commercial refrigeration equipment, Ice cream machine should work in following condition:
Ambient temperature: 5~40℃ Mixing temperature: 2~35℃
Power : 198~235V/1PH Frequency range : 50/60±1Hz
Caution:
Lower ambient temp, proper ventilation, steady voltage, clean conditions and the temp
of the mix is as low as possible will make the machine has a higher efficiency, less
electricity consume and long life.

Ⅳ、Use and Cautions
Many customers summarize a lot of recipe to make different ice cream when using this machine.
We suggest you make ice cream powder as follow.
A
、
Recipe
：
Ingredient ( weight ratio)
full cream milk power (8%) white sugar (16%) flavor ( a little)
emulsion stabilizer (0.5%) water (75%) food color( a little)

B、Prepare ice cream mixing:
①Weight all materials as above table
②Put all materials into container and mix it slowly and equality.
③Put into the boil water, mixing it rapidly, assure all the mixer have dissolved (the boiled
water is the half of the total water)
④Put into some essence, pigment and water, mixing it when put the powder, make sure all the
mixer have dissolved.

AT TT TE EN NT TI IO ON N: : 
In this recipe, the proportion between milk power and sugar is
economy type it can not be reduced any more, It will freeze and damage
the machine if content of sugar is less this proportion or substitute
saccharin for sugar. Stabilizer is to improve emulsification and
overrun and prevent from freezing.
The mixer should be mixer equally and dissolved completely. Be sure there
is not grain in the mixing. All materials and utensil should meet the
Hegelian required. Above two times input water volume should meet the

For safety, ensure the ground connection is in good condition.
All the exterior wires and other appliances must confirm with national standard.
Ⅴ、 Installations And Adjusting
A. unpack and inspect
1) Cut off the wrapping tape.
2) Open the wooden case by screwdriver.
3) Remove the foam.
4) Inspect carefully whether there is defective appearance or not.
5) Check the accessories with packing list.
6) Remove the fixing bolt and fixing feet that are at the bottom of the machine, push the machine,
let the front-wheel drive fall to the ground, and then take out the wooden base, let the
four wheels grounded. (Directly lift the machine to the ground or on the table if the machine
is table type)
B. Installation
1) SELECTING LOCATION
a. Place the machine on a level counter that is stable and strong enough to safely support
its weight.
b. Place the machine in a location that allows adequate space at the back and each side
for proper ventilation. Keep 50cm space from all sides of ventilation. The machine should
shade from the sun and should not be located too close to the units that radiate excessive
heat.
2) POWER SUPPLY
a. Select the proper power supply according to the voltage and power on the nameplate.
b. Connect the power wire and the power supply, ensuring the yellow and green wire was connected with
the ground wire firmly.

C
、 The Pre-cool of the mixer
In order to let the machine run more efficiently. It is necessary to pre-cool mixing.
Normally, you can put the mixing on the cool place, let the well-prepared mixing cool by
itself .If you have freezer, you can put the mixing into it and pre-cool it to 0~40℃.
D
、 Keystroke and Direction
1）、HD6-8L、HD8-10L
Pour ice cream mixing into the hopper,2.5kg every time, turn on the machine, the mixer
begin to mix the ice cream, then rotate the timer according the arrowhead direction, the
refrigerate system begin to work(when the timer rotate according the arrowhead, rotate
large angle will spend longer time, opposite, will spend shorter time).the timer will
stop work when the ice cream make finished, if the timer didn’t stop work, meaning the
time of set is over long, in that case ,you can re-turn on the timer (because it need 3
minutes after restart the machine .so it ‘s better to set a little longer).if the ice cream
have already made, but the timer still didn’t stop work, this meaning the set time is so
long ,you can press the off button to stop it directly, After some time practice, you can
set the time accurately, press the off button as soon as the timer stop work, the mixing
box can be put into the freeze. And then input mixing, turn on the machine, start to work
again.
HD8-10LInstall the blender：
The plastic scraper and stainless flexible sheet are located at the bottom of the
blender, the nylon scrapers at both side of the blender, as the following drawing:
The plastic scraper is flexible, the hole on the scraper can be pull bigger to fit on

the screw, and then install the flexible sheet on it, if the sheet too tight, put some Vaseline
on it. When install the nylon scraper, face the tooth of the nylon scraper downwards and
press it to the charging basket tightly.
ATTENTION：
Note: if the scraper direction to be opposite, it will affect blows the frost effect.
2）、HD12-15L、HD20-25L
zBefore making ice cream ,you adjust suitable time and press Enactment-Key 3s.Display
twinkling ,the twinkling number is last-time one. If you feel too soft, you can adjust
Enactment-Key. Each adjusting make the machine to work increase 1 minute. The least time
is 5 minutes and the most is 25 minutes. During 5s,no any operating, the
control-Microcomputer will exit. Whole course for moulding take 15 minutes and different
material take different time. Pour ice cream mixing into the hopper,2kg every time for
HD12-15L or HD16-20L, 2.5kg every time for HD20-25L.
zAfter adjusting suitable time, press Auto-key and then leftward Indicator-light shine,
beater system start working .Waiting 3s,referentent system start running. Then number
display showing reduce step by step, When it is O ,the compressor will stop. The beater
continues working.
zPress Clean-key, beater system work for clean.
zAnytime, as long as you press Pause-key the machine will stop.

zWash
Press “Wash” key ，the corresponding indicator light flashes, the beater system start to
work.
zTemperature adjust button
Please set the hardness of ice cream before make it, When the machine tune on (the digital
display “00”)，Press hardness adjust button more than 3 second，the digital display flashes，
the flashed number means the hardness to be set different type. For example, the number is
“02”, means the hardness is type 2. at first use, you should not set a high type. Generally
start from type2. If the ice cream is soft, you should press button 。
to adjust the hardness, press the button one time，the hardness will add 1 type. The type
display from“01”to“10”circularly，the number is bigger, means the type is higher and ice
cream is harder。
zAuto
Press auto key after you adjust hardness，the corresponding indicator light flashes，the beater
system start to work, three seconds later the refrigeration system start to work. The digital
display will display number, which means the percentage of hardness. For example,“58”means
the hardness have already reached 58%.The number will increase after the machine works a few
minutes. The machine stops automatically (digital display “00”) while the ice cream hardness
reach 90% of you set the hardness. That means the ice cream is ready. Different ice cream powder
