Model BH7480 units use air cooled refrigeration systems
and require a minimum of 6-8 inches of clearance around
the sides of the machine and 8 inches around the back pan-
el to allow for adequate air flow. Failure to allow proper
clearance will restrict the airflow into the machine, will re-
duce the refrigeration capability, and will likely cause over-
heating and/or damage to the cooling system of the ma-
chine.
The BH7480 is shipped on a pallet and the machine is secured/
bolted to the pallet to prevent shipping damage. To install the
machine, the bolts connecting the pallet bracket to the base of
the machine must be removed. Once the pallet bracket bolts are
removed, the machine may be carefully removed from the pallet.
USE EXTREME CAUTION REMOVING THE MACHINE
FROM THE PALLET. Professional unpacking and installation
is recommended due to the weight of the machine and poten-
tial bodily injury due to improper handling.

This equipment is intended to be installed in ac-
cordance with the National Electrical Code (NEC),
NFPA 70. A licensed electrician must install the
electrical connections for the machine to insure
safe operation. The machine must be properly
grounded. Failure to properly ground the machine
can result in severe bodily injury from electrical
shock.
ELECTRICIAN — When making the electrical connections,
note that the beater rotation must be counter clockwise as
viewed looking into the freezing cylinder from the front of the
machine. If the rotation direction is incorrect, it will be neces-
sary to change the position of the hot wires in the machine plug
to allow the motors to rotate in the correct direction.

To operate the machine in any mode, the main power switch must
first be turned to the “ON” posion.
The machine has 3 operang modes:
1) Wash Mode: This is when the refrigeraon system is turned offand
the mixing motors are running. You use this mode to circulate
cleaning or sanizing soluon through the machine hopper and bar‐
rels.
2) Auto Mode: This is the normal operang mode of the machine
where the refrigeraon system and the mixing motors are on so
that the machine is freezing and preparing soserve product to
serve.
3) Standby Mode: This is where the machine is configured to keep the
product in the barrels refrigerated for extended periods of me
(during slow sales periods or even overnight).
OPERATING IN THE WASH MODE:
Press the “Wash” buon and the “Wash ” indicator light will turn on.
Both the right and lemixing motors will turn on simultaneously. To
stop, simply press the “Wash” buon again. During the Wash Mode,
the refrigeraon system for the freezing cylinders will be OFF. Wash
Mode only rotates both beaters inside of the freezing cylinders with‐
out any freezing. Wash Mode is used to drain mix from the machine or
rinse the beater assemblies with water or sanizing soluon.

DONPER USA—USER MANUAL
15 — COPYRIGHT DONPER USA 2015
OPERATING IN THE AUTO MODE:
There are two Auto buons on the front control panel, one for the le
barrel and one for the right cylinder. The two sides can be controlled in‐
dependently of each other. Press the Auto buon on the control panel
to begin freezing inside the corresponding freezing cylinder. When in
Auto Mode, the indicator light will turn on along with the corresponding
beater motor. The numeral values on the display will increase from 0 to
99 and then stop at 00. When the number value reaches 00, this indi‐
cates that the product in the freezing cylinder is ready to serve. When
the number reaches 00, the indicator light above the AUTO buon will
then flash, indicang that the product is ready and has reached the de‐
sired firmness level. Note that the hopper cooling switch should also be
turned on during the AUTO mode operaon to keep the product in the
hoppers refrigerated and to prevent spoiling. NEVER RUN THE MACHINE
IN AUTO MODE WITH WATER IN THE FREEZING CYLINDERS—DAMAGE
WILL OCCUR.
Adjusng the Product Firmness Level:
With the Power Switch ON and both Auto buons OFF, press the up and
down buons simultaneously and hold for 5 seconds (machine will beep
5 mes) for the side you wish to adjust. A numerical value of 1 to 10
(the firmness seng) will begin to flash on the screen. Use the up and
down buons to adjust the firmness seng with 1 being soer product
and 10 being firmer product. Once the firmness is set, the control panel
will automacally return back to “00” aer about 10 seconds of no fur‐
ther adjustments.

DONPER USA—USER MANUAL
16 — COPYRIGHT DONPER USA 2015
Adjusng the Product Firmness Level: (cont’)
The recommended starng seng for the product firmness level is 5.
With your product in the machine for the first me and the AUTO fea‐
ture running, wait unl the display cycles from 0 to 99 and then shows
00. Dispense some of the product from the machine and check the con‐
sistency/firmness. If a firmer product is desired, then increase the firm‐
ness seng by 1‐2 and allow the machine to recycle back to 00 again
and retest the firmness. Repeat this process unl the desired product
firmness is reached.
As a guide to help determine the appropriate product firmness seng,
the numbers on the display in AUTO mode should start at 0 and quickly
rise to about 84 to 87 when the product inside the freezing cylinders is in
a complete liquid state (for example, when the machine is first filled with
fresh product and started aer cleaning). If the numbers rise above 87
to start, then increase the firmness seng 1‐2 number values and re‐
start the AUTO mode and observe if the numbers stop increasing rapidly
somewhere near 84‐87.
OPERATING IN THE STANDBY MODE:
During long non‐use periods, the machine can be placed in Standby
Mode in order to keep the product inside the freezing cylinders refriger‐
ated.

DONPER USA—USER MANUAL
17 — COPYRIGHT DONPER USA 2015
OPERATING IN THE STANDBY MODE: (cont’)
To start the Standby mode, with the machine in Auto Mode on both
sides, press and hold the Wash buon for five (5) seconds (machine will
beep 5 mes), then release. The LCD displays will now alternate be‐
tween “00” and “bb”. Both mixer motors will turn offand the refrigera‐
on system will keep the product in the cylinders refrigerated. In this
mode it is also necessary to make sure that the hopper cooling system
switch is set to ON. Not turning the hopper cooling switch on will allow
the product in the hoppers to spoil.
To enter standby mode you must also remove the feed tubes from
inside the hoppers and reverse their position, as shown above. To
do this you first remove the air caps from the top end of the feed

tube and insert into the bottom end. Now, insert the feed tubes
back inside (reverse insertion positioning) the hopper to prevent
product from entering the freezing cylinder. The hole-side of the
feed tube should now be at the top.
When in the Standby Mode is it also advised to remove the valve
caps (typically the star shaped caps) from the dispensing aperture
of the valve body. You should also remove the drip tray and drip
tray cover. These parts should be sanitized upon removal and
dried for later use. The exterior of the machine, and specifically
the valve body, should also be cleaned and sanitized.
To exit Standby Mode and return to normal operation (Auto Mode),
press and hold the Wash button for five (5) seconds (machine will
beep 5 times), then release the Wash button. The machine will re-
turn to the Auto Mode when the Wash button is released and will
begin rotating the augers and cycling the refrigeration system so
that the product is frozen to the selected consistency.
When exiting the Standby Mode and returning to the Auto mode,
the feed tubes must be reversed from the Standby position with
the holes positioned on the top of the feed tube to the normal op-
erating position with the holes being nearer the bottom so that the
product mix can flow into the freezing cylinder. Failure return the
feed tubes to the Auto position may result in damage to the ma-
chine.

Draining Product from the Machine
Step 1: Turn the Auto Mode OFF for both freezing cylinders.
Place the hopper cooling switch in the OFF position.
Step 2: Remove the hopper lids and feed tubes from the hop-
per. Remove the all of the star caps from the dispenser valves.
Step 3: Unscrew the Adjustable Flow Rate Screws in the han-
dles to allow the draw valves to fully open.
Step 4: Place a large bucket beneath the dispenser door. Press
the Wash button. Pull and hold all three (3) handles down until
all the product is removed from the freezing cylinders and hop-
pers. Press the Wash button to turn Wash Mode off.
Step 5: Pour water/cleaning solution into the hoppers and re-
peat step 4 until the water being drained into the bucket comes
out clean.
Cleaning the Machine (Quick Rinse & Sanitize)
Every 2-3 days the machine should be shut down and fully
cleaned. For mix changes or sanitizations between product
changes, follow the steps below.
Step 1: Pour a gallon of room-temperature water into each hop-
per. Allow the water to flow down into the freezing cylinders. Us-
ing a tube brush, clean the inside of the hoppers including the L-
shaped level probes.
Step 2: Press the Wash button and run in Wash Mode for 1-2
minutes.

Cleaning the Machine (Quick Rinse & Sanitize cont’)
Step 3: While the unit is in Wash Mode, place a large bucket be-
neath the dispenser door. Pull and hold all three (3) handles
down until all the water is removed from the machine. Press the
Wash button to turn Wash Mode off and discard the water.
Step 4: Repeat this rinse process 2-3 more times until the dis-
carded water becomes clear.
Step 5: Repeat steps 1-3 using water containing approved sani-
tizing solution and then rinse with a water solution.
Step 6: If the machine is to be immediately run with new product,
then pour 1-2 cups of the product into the hoppers, activate the
WASH mode, and dispense the product out the valves until the
water remaining in the cylinders is pushed out by the product.
If the machine is not going to be run immediately with new prod-
uct after cleaning, you will need to remove the dispensing door
and beater bars and dry the freezing cylinder and beater bar
components to prevent corrosion or oxidation (rust). Once you’ve
removed the dispensing door and beater bars it’s a good practice
to go ahead and do the full clean processof the components in a
sink with warm soapy water before reassembling the machine
parts (after clean rinsing and drying all parts).
