Section 2 – SAFETY
First, be sure to read and understand this machine manual, and
familiarize yourself and other operators with the machine features, its
operation, cleaning, and maintenance.
Your machine is equipped with several important safeguards that should
never be removed or altered. DO NOT remove the following items:
 Inlet spout combination lid and gate – restricts fingers from
coming in contact with moving blades/dasher.
 Door discharge guard – restricts fingers and utensils from
coming in contact with moving blades/dasher. Also, in
combination with the discharge chute, funnels product into
smaller containers neatly.
The sides, front, and rear section of the machine have ventilation
openings in them. All but the rear panel are louvered to deflect food and
splashing liquids away from the inside. Never spray water directly
at/into these openings.
If your machine is set up with a plug on the end of its cord, make
absolutely sure your hands are dry when plugging it in, or unplugging it.
When operating the machine, avoid distractions such as conversations,
television, small children, etc.
The door and the dasher are heavy parts and are slippery when wet.
Use extreme care handling them. Keep the floor and work area neat
and dry to avoid slippage. Do not use the top of the machine as a
storage spot.
In addition to the above:
 DO NOT operate your machine unless it was wired, grounded,
and properly fused by a licensed electrician.
 DO NOT put fingers, hands or any utensils in either the inlet
spout or door outlet.

- 7 -
v. 3.20
Emery Thompson CB-350 Countertop Batch Freezer
 DO NOT operate the machine unless it is properly assembled
and all guards are in place.
 DO NOT force any of the (washable) parts together or into/on the
machine. All parts should fit together easily.
 DO NOT operate the machine with the freezing cylinder empty.
 DO NOT turn on the machine’s refrigeration switch with only
water in the freezing cylinder.
 DO NOT let your product over-freeze during production. This is
the most common mistake a new operator makes.

v. 3.20
Emery Thompson CB-350 Countertop Batch Freezer
Section 3 – UNPACKING
Carefully inspect the pallet and shipping carton for any signs of damage
during shipment; if damage is suspected, have the freight company note
it on the bill of lading, and if possible, take photographs.
The shipping carton is stapled to two wooden runners inside*. Using a
razor knife, carefully cut through the carton all the way around its
perimeter JUST ABOVE the staple line. The carton is approx. ½” thick.
Once free, the carton should be lifted straight up and off of your
machine. You will find a small box of parts that will be explained in
subsequent sections; set them, as well as all paperwork, aside in a safe
place.
The machine is bolted to the pallet it was shipped on from the underside.
There are four hex bolts (9/16” head) that go through the upper planks
of the pallet, and into the machine frame. Remove all four bolts, and
also unscrew one wooden side runner from the pallet. The machine will
now be free from the pallet. Save all components; they can be used at
a later date to safely move the machine.
* If your machine was exported outside of North America, it will have an
all wood box over it fastened to the runners with removable screws.

Emery Thompson CB-350 Countertop Batch Freezer
Section 4 – INSTALLATION
Your new machine weighs 275 pounds and has momentum when
running; therefore, it must be operated on a surface/stand/counter
capable of supporting it. It will take a minimum of two people to safely
lift it.
In the smaller carton that was included with the machine, there are 4
screw-in feet; these should be installed into the threaded holes on the
underside of the machine’s frame, where it was previously bolted to the
shipping pallet. These allow for minor uneven surfaces.
NOTE: If you also purchased the heavy-duty machine stand, you will
not be using these feet; follow instruction in the kit that comes with the
stand.
The stainless-steel shelf clips onto the louvers on the front lower panel;
it is adjustable for various height containers/trays.
NOTE: The protective plastic film on most outer surfaces of the machine
protects the finish during shipping. This film MUST be removed prior to
operation of the machine to allow proper airflow and heat dissipation.
The machine MUST be able to pull in cool, clean room air from its rear
intake. It requires a minimum of 10 inches of clear, unobstructed space
on all 4 sides. Failure to allow the adequate spacing and/or not
removing the protective plastic film may result in poor performance,
overheating, and shutdown.
ELECTRICAL CONNECTION: The model CB350 machine comes with
a 72 inch long flexible power cord that has an L14 - 20 locking male plug
installed on it. It MUST ONLY be connected to a matching receptacle
which has been wired to a dedicated and fused 20-amp circuit. Your
machine has a wiring tag on its cord, as well as electrical specifications
on its serial number tag on the rear of the machine. Your electrician can
also call us for technical information if necessary, during business
hours.

Section 5 – CLEANING & SANITIZING
NOTE: Your local or state health inspector will always have
jurisdiction over the methods and cleaners he/she prefers for the
proper cleaning and sanitizing of this type of equipment. Our
instructions are based on industry standard methods but should
be discussed with your inspector.
The first step toward insuring a clean and sanitary machine is to
understand the various parts that will or could come in contact with the
food product. Please see figures 8-1A (Page 30) and 8-1B (Page 31)
to familiarize yourself with these parts.
All of these parts are dishwasher safe and relatively small, so the easiest
way to clean them is to carefully arrange them in a dishwasher,
positioning them so that open holes, pockets, and internal areas face
down and stand the best chance of being hit with hot soapy water. Any
of these parts can also be cleaned with liquid dish detergent and hot
water, so long as they are thoroughly rinsed. The inside of the cylinder
will have to be manually wiped out with warm soapy water and
thoroughly rinsed.
The following list of components should be cleaned at the end of the
day/shift, or if food product has sat in the machine for one hour or more:
- all parts on diagram 8 – 1A
- all parts on diagram 8 – 1B, except “ASSY006”, part 1 and 3
(these parts are inaccessible, and do not come in contact with
food). Part #2 of this assembly protrudes into the freezer and
should be cleaned/wiped when cylinder is cleaned.
Prior to each use your machine must be sanitized. The purpose of
sanitization is to kill any bacteria that may have grown on any food-
contact part or surface.
To properly sanitize your machine, it must first be reassembled after
cleaning. Before putting the dasher/blades assembly back into the
machine, note the end of the dasher shaft has two o-rings in it. These
two o-rings, and the circumference of the shaft just forward and
rearward of the o-rings should have a generous coating of food-grade

- 11 -
v. 3.20
Emery Thompson CB-350 Countertop Batch Freezer
grease wiped on them (See diagram 8-1B/Dasher shaft, and Part 6 O-
Rings, Page 31). Once installed, any grease pushed off the shaft can
be wiped off with a paper towel. NOTE: Before installing dasher/blade
assembly into cylinder, ensure that the rounded end of each scraping
blade is toward the rear. (See Diagram 8-1B, Page 31.)
When the machine is fully assembled, with the door in place, and the
four knobs hand tightened (do NOT use any tools), it is ready to be
sanitized.
We recommend using a commercially available sanitizer/cleaner made
by Purdy Products Company called “Stera Sheen Green Label”,
although other brands exist as well. Carefully follow the manufacturer’s
instructions on mixing and use of their product.

Section 6 – OPERATION
Your new batch freezer is very easy to operate, with only two controls
on it. The machine was shipped fully assembled, and its’ parts and
features should be learned and understood.
On the upper right of the face of the machine, there is a pushbutton
switch. This energizes the refrigeration condensing unit. Push in the
button for “on” and push in on the button for “off”. In the “on” position,
the button will illuminate blue. Ensure that the button is in the “off”
position.
When electrical power is first applied to the machine, the compressor
will immediately start, regardless of the position of the refrigeration
button. The compressor will also start occasionally and run briefly, even
if the machine sits idle if there is power connected to it. This is a normal
function, and actually helps prolong the life of the compressor.
