POWER REQUIREMENTS
Compressed Air
Minimum Compressed Air Requirements: 4 cfm @ 80 PSI. (5.5 Bar)
Typical compressor requirements: Minimum 2 horse power, capable of 4
C.F.M. @ 100 P.S.I. (7 Bar). 5 HP is the ideal size, as it will last many
years longer than a smaller unit.
Connect the main air supply hose (minimum 3/8” inside diameter) from
your compressor and air dryer (not supplied) to the UNIFILLER male
quick connector that is located just below the machines Air regulator /
Water filter.
Note: Female quick disconnect fitting (Unifiller Pt #1120).
Air Pressure Adjustment
To adjust the machine air pressure:
Pull UP the black air regulator adjustment cap/knob on the top of the
regulator assembly
- Turn CLOCKWISE to increase air pressure.
- Turn COUNTER CLOCKWISE to decrease- the air pressure.
Recommended Settings:
Adjust the air pressure as follows:
Machine at Rest - Adjust to: 80 P.S.I. (6 Bar)
Machine Cycling –Adjust to 70 P.S.I. (5 Bar) minimum
After the air pressure is set, depress the top cap to lock the setting.
Important:
The compressed air supplied to the Mini Dopositor must be filtered and dried prior to connection to
the machine. Failure to comply will result in damage to the machine and the warranty will become
void.
Electrical
Minimum Electrical Connection Requirements:
System Voltage: 208 - 230 VAC 60 HZ, Single Phase
Current: 15 Amps

PRODUCTION SETUP & OPERATOR ADJUSTMENTS
The main components of the Mini Dopositor module are the foot pedal, auger and rotary valve. These
can be adjusted to handle different products and patterns of depositing
Priming / Preparing to Deposit
Priming is the procedure used to fill the depositing die/chamber with product mix as well as to remove all air
pockets from within the empty machine.
1. Fill the hopper with small blocks (the size of a hand full) of dough.
2. Turn the air supply and electrical power to the machine on.
3. Start the Mini Dopositor and run in continuous mode until dough is consistently extruding from the die
port.
4. Observe dough level while priming. Addition of more dough may be required so as to prevent air
pockets from forming and restricting the dough from entraining into the auger.
Adjustments
1. Set your desired cut rate to accommodate your production demands, up to 60 cuts per min
2. To regulate the deposit weight, first adjust the auger speed to achieve desired weights. Increasing the
auger speed will force more dough thru making heavier deposits and decreasing the auger speed will
reduce the amount of dough therefore reducing the deposit weight.
3. If targets are not achieved thru adjusting the auger speed, adjust the cut rate accordingly. Lowering the
cut rate will increase the weight of the deposit whereas increasing the cut rate will decrease the deposit
weight.
4. Once the appropriate parameters have been set to achieve the desired deposit weights, the combination
can be saved as a recipe specific to that type of dough.
Operation:
1. When in continuous mode, one push of the foot pedal will start the Mini Dopositor and commence the
conveyor belt and the selected cutting cycle. When you depress the foot pedal a second time it will
cease the cutting cycle.
2. When in Foot Pedal mode, each depression of the foot pedal will create a deposit. Conveyor belt will
continue to move but there will be no deposits unless the foot pedal is depressed.

DISASSEMBLY AND CLEANING
Empty Product from Machine
1. Run the Mini Dopositor until the contents of hopper are empty.
2. Turn power switch to OFF.
3. Turn the air supply OFF.
Cleaning
Safety –Always follow appropriate lock out procedure prior to performing any cleaning or
maintenance on Mini Dopositor.
FOR CLEANING PURPOSES DO NOT USE ANY STRONG ALKALIS (BASE) SUCH AS
CAUSTIC SODA OR SODIUM HYDROXIDE NOR ANY ACIDS AS THIS WILL DAMAGE THE
ELECTRICAL, AIR AND MECHANICAL COMPONENTS, AS WELL AS THE FINISHES ON
THE METALS.
1. Turn power switch to OFF.
2. Turn the air supply OFF.
3. Remove the rotary valve by disconnecting the quick connect hose fittings. Remove the tri clamp
which holds the rotary valve to the hopper
4. Remove any leftover dough from the hopper outfeed section.
5. Disconnect the auger shaft from the motor shaft by raising the coupling guard and unlatching the
coupling. Turn coupling 90degrees to keep coupling disengaged. Remove the hopper and auger by
unlatching the toggle clamps from the frame. Separate auger from hopper prior to cleaning.
6. The entire machine can be washed down, but do not spray high pressure water directly onto the
touch screen and electronic components.

Unifiller Systems Inc. Page 14 of 48 Manual Part No.: MINI
DOPOSITOR
Inspection and Reassembly
1. Place auger into hopper prior to reassembly.
2. Reattach hopper to frame by aligning and latching the 2 toggle clamps
3. Align and re-attach the auger shaft to the motor shaft and slide coupling into place.
4. Place die into proper position prior to attaching safety guard to hopper. Slide Safety guard with
cutting mechanism attached back into alignment with the hopper outfeed.
5. Replace and secure the triclamp around the hopper outfeed.
Note:
If you need assistance on troubleshooting your machine, please copy and fill out the Unifiller
Diagnostic Record Log at the end of this manual before contacting Unifiller whenever possible.
Conveyor Belt Tracking and
Tightening
The Conveyor belt is designed to run in the
center of the conveyor bed.
If the belt moves excessively to one side, turn
the nut to tighten the “high” side to steer the
belt back to center.
If the conveyor belt is slipping, tighten both nuts to increase the tension of the conveyor belt.
CAUTION:
Do not tension belt excessively as it will cause premature failure of the motorized pulley and idler
pulley.
Always ensure there is no moisture between the belt and conveyor bed as this will produce a wet
bond of the belt to the bed. This will prevent movement of the belt and lead to premature wearing.
Proper and safe belt tension is achieved when the belt slips on the drive pulley when the belt is
pressed firmly onto the conveyor bed.
