3. Inspect for damage immediately upon unpacking and call Donper USA Technical
Service if you discover any damaged or missing parts.
4. Clean and properly lubricate machine parts prior to machine operation.
Aer unpacking and inspecting the parts, you are ready to disassemble the machine
and prepare for the rst operation.
PRIOR TO OPERATING
Aer you have unpacked and set up your machine for use, we recommend running
the “CLEAN” cycle for a few minutes with a mixture of 1-table spoon of bleach per
gallon of water to ensure sanitization. Fill the freezing cylinder and hopper with this
mixture then run “CLEAN” cycle for about 2 minutes. Dispense the water and repeat
for best results.
For more information please visit our website www.donperusa.com for instructional
videos on how to adjust this setting.

CONTROL PANEL
(L) (R)
To operate the D250 control panel you first need to get the machine into “READY
MODE” (this is when the machine is plugged into its power source and the power
switch is in the ON position).
The symbols below will show up throughout this manual on images of the control
board buttons. If you see one of these on a button, be sure to interact with the
button according to the description.
Operating the D250 is all done through the control board. On the control board there
are 6 buttons, each of which has its own function. Pressing and holding dierent com-
binations of the buttons unlocks dierent settings which the user can adjust to t their
needs.

1. Verify machine has been recently sanitized (within 1 hour)
2. In a separate container, thoroughly mix and prepare product according to manu-
facturer instructions; mix should be cool and free of large chunks

4. Pour product into hopper until freezing cylinders are full
5. Verify the freezing cylinder that you want to use is full of
mixed product.
3. Remove feed tubes in order for the mix to move into the
freezing cylinder more quickly.
6. With the machine in ready mode, pressing the le “AUTO” button will begin
freezing the le freezing cylinder and cooling the le hopper. Pressing the right
“AUTO” button will begin freezing the right freezing cylinder and cooling the
right hopper.
7. e number displayed on the le side of the control panel above the word “HARD”
is the percentage of how ready the product currently is inside the le freezing cyl-
inder based on it’s “HARDNESS SETTING”.

14 15www.donperusa.com Phone: [phone] Email: [email protected]
For example, when your mix is in its liquid form its hardness percentage will be
closer 00. As it begins to freeze and change into its ice cream state, the percentage
will begin to go up. Once the percentage reaches 99 the compressor will shut off
and your ice cream is ready.

9. With the product now ready to dispense, pull the draw valve handles to dispense
the product. e side draw valve handles dispense product from their respective
hoppers. e middle draw valve handle dispenses product from both hoppers to
form a twist of the product.

When the machine will NOT be utilized for several hours, place it in STANDBY mode
to conserve electricity and reduce product loss. While in STANDBY, the product in
the freezing cylinders remains cold but may not be frozen. See STANDBY details for
how the machine functions during STANDBY.
To enter “STANDBY” mode:
1. Verify the machine is back in “READY MODE”. If either freezing cylinder is in
“AUTO MODE” press the “AUTO” button for that side and the machine will re-
turn to “READY MODE”.
2. Press the “STANDBY” button to enter “STANDBY MODE”.
To EXIT “STANDBY” mode:

e following is a brief guide as to how the FREEZING CYLINDERS operate while
your machine is in STANDBY MODE.
1. When the machine is placed into STANDBY MODE, the compressor and drive
motor will power on.
2. e solenoid valves to the freezing cylinders will open and begin to freeze for 15
seconds and then close for 7 minutes repeatedly.
This cycle continues the entire time the machine is in “STANDBY”, and the tempera-
ture in the hoppers is below 20ºC.
This cycle continues the entire time the machine is in “STANDBY”.
3. e solenoid valves to the hoppers will open and close depending on the tem-
perature of the mix inside the hoppers. When the temperature in the hoppers is
above 20C, the solenoid valve will remain open in order to continue cooling the
hoppers.
4. Once the temperature inside the hoppers has dropped below 20C, the solenoid
valve will begin cycling, open for 30 seconds and closed for 7 minutes.

Hardness Setting - this setting is referring to the consistency of your product. is
setting ranges from “01” which is a soer/less frozen setting for your product and “10”
which is a harder/more frozen setting for your product. e factory settings for the
D250’s hardness is set at “01”. We nd this setting seems to be ideal for most indoor
installations.
