Model 220Operating Procedures
Step 5
If the scale does not have overrun graduations, then
weigh one pint (1/2 liter) of mix before freezing. Draw
a sample pint (1/2 liter) of frozen p roduct and level it off
with a straight edge.
Step 6
Place the pint (1/2 liter) of product on the scale and
read the weight. Dividethe weight of the frozenproduct
into the weight of the raw mix for your percent of
increase. If the answer is 2, you have 100% overrun.
If the answer is between 1 and 2, the decimal
represents your overrun.
Example:
1.85
8.2
15.2
Raw Mix = 15.2 oz. (450 ml)
Frozen Mix = 8.2 oz. (243 ml) Overrun = 85%
Drawing Product
Step 1
When the desired temperature and overrun of the
product has been achieved, the product may be drawn
into packages or cans for hardening. Place the
package or candirectly beneath the ejection port of the
freezer door.
Step 2
Put the control switch into the “EJECT” position and
place the container on the shelf.
T urn the draw rod handle and pull forward, opening the
ejection port. When the container is full, push the draw
rod back into the valve body and lock into place.
Step 3
When the freezing cylinder is empty of product, close
the ejection port and place the control switch in the
“OFF” position.
Note: The shelf can be adjusted for large or small
containers. Lift upwards on the front edge of the shelf
to disengage from the holding collars; then lift away
from the freezer. Choose the desired height and slide
the shelf back down over the holding collars of the
same height on right and left sides.

Closing Procedures
After the necessary batches have been prepared, the
machine should be cleaned and sanitized. The
following procedures will show you how to rinse the
freezing cylinder of mix residue, clean and sanitize,
and disassemble the parts from the freezer.
Rinsing
MAKE SURE THE CONTROL SWITCH IS
IN THE “OFF” POSITION. Failure t o follow this
instruction may result in severe personal injury from
hazardous moving parts.
Step 1
Remove the hopper cover, the gasket and the funnel.
Take these parts to the sink for cleaning.
Step 2
Pour two gallons (7.6 liters) of cool, clean water into
the mix hopper. With the brushes provided, scrub the
mix hopper and the mix inlet hole.
