1Make sure the socket is connected to the ground.
2Make sure the power supply has a circuit-breaker or any other device for
protection against electric shock.

3The section area of power code copper core(a) MUST BE:
18L machine,20L machine: a≥2.5 ㎡36L machine,48L machine:a≥4 ㎡
4Under-size power code can result in low voltage and overload,which affect
machine performance or causing damage.
3) Installation
1Open the carton bag,you will find a parts bag in the hopper.In the parts bag you
will find consumable parts,keep the spare parts for the future replacement.
①Horn-shaped rubber rings
②Caps
③O-rings
④H-rings
2Please check the nameplate on the right panel,confirm this is the correct
model(voltage,frequency and power)you order.
3Install the discharger properly,tighten it to the
machine with 4 bolts(2 long ones up,2 short ones
down),screw the 2 bolts in diagonal at the same
time,mate sure no gap between the discharger and
the machine,otherwise,water or mixture can leak
from it during washing or making ice
cream.Notice:sensor plate MUST BE on top of all
valve stems.(see right photo)
④Install the handles to the valve stems one by one ,in the mean time,slowly push
the steel pin through the discharger and the handles.(Refer to below photo for the
correct direction of the handles)
5.How to Make ice cream
1) Wash
Connect it to 16A socket,switch on the power
with the stick on the left down part of control
panel.Pour water from the hoppers to fulfill
the cylinders,press“CLEAN”mode.Repeat this
2-3 times,until the water comes out is all
clean.
2) Make mixture
Currently in the market,there are ready-made mixture of ice cream,or the powder
that needs to mix with water.Please follow the instructions and formula on powder
package(generally speaking:1kg powder to 2.5-3kg water),stir them even,let them
completely dissolve and mix together,avoid lumps forming,leave it still for 30
minutes.These are very important factors for the texture and amount of the ice
cream later produced.

3) Make ice cream
①Make sure water is completely drained,them pour the mixture into the hopper.
②Press“CLEAN”(beater will start to rotate,to beat
it even),after 2 minutes,press“STOP”,then press
“WORK”to start freezing(Notice:Make sure the
mixture level in neither cylinder should be lower
than the inlet of discharger,or else can result in
loud noise or damage.)
③In “forming”mode,displayer shows the
progress of ice cream making,generally
speaking,when it reach 80% ,the ice cream is
ready for dispensing.When it reach 100%,the
machine will stop automatically and back to
“Standby”mode.
④Serve:Put a cone or a cup under the
nozzle,press the handle down,slowly rotate the
cone in hand,press the handle back to stop.
