Section 1To the Installer
These machines are designed for indoor use only.
DO NOT install the machine in an area where
a water jet could be used to clean or rinse the machine.
Failure to follow this instruction may result in serious
electrical shock.
Air Cooled Units
Air cooled units require 6” (152 mm) minimum air
space around all sides. Failure to allow adequate
clearance can reduce the refrigeration capacity of the
freezer and possibly cause permanent damage to the
compressor(s).
Water Cooled Refrigeration Units
(Water Cooled Units Only)
Failure to use adequate size water lines may cause the
unit to go off on high head pressure and shut down.
Depending on local water conditions, it may be
advisable to install a water strainer to prevent foreign
substances from clogging the automatic water valve.
Water Connections
An adequate cold water supply must be provided
with a hand shut-off valve. On the back of the unit, a
3/8” (9.5 mm) M.F.L. water connection has been
provided for easy hook-up. A flexible line is
recommended, if local codes permit. A minimum of
25 psi water pressure is required to avoid having the
unit cut out the low water pressure switch. A booster
pump must be provided if this pressure is not
available.
Note: Water lines beyond 200 ft. (61 m) require 1/2”
(13 mm) water lines.
INSTALL POTABLE WATER CONNECTION
WITH ADEQUATE BACK-FLOW
PROTECTION TO COMPLY WITH
APPLICABLE NATIONAL, STATE AND
LOCAL CODES.
It is always a good practice to have a filter system to
improve the quality of the water and to avoid
clogging the operating components.
IMPORTANT: The water filter (064422--SER) must
be thoroughly flushed with water before connecting it
to the machine. This removes carbon particles that
could clog the flow control. To flush the filter,
connect the inlet end of the filter to the water supply.
Position the outlet end of the filter over an empty
pail. Open the water supply. Allow water to flow
through the filter until the water exiting the filter is
clear. Close the water supply. Attach the outlet end
of the filter to the machine. Reopen the water
supply.
There are two water “in” connections and one water
“out” line connection. DONOT installa hand shut-offvalve on the water “out” line! Water should always
flow in this order: first, through the automatic water
valve; second, through the condenser; and third,
through the outlet fitting to an opentrapdrain.
IMPORTANT: Water pressures are pre-set at the
factory. Do not adjust the water. Improper water
adjustments may cause operation discrepancies.

Compressor Warranty Disclaimer
The refrigeration compressor(s) on this machine are
warranted for the term indicated on the warranty card
accompanying this machine. However, due to the
Montreal Protocol and the U.S. Clean Air Act
Amendments of 1990, many new refrigerants are
being tested and developed, thus seeking their way
into the service industry. Some of these new
refrigerantsarebeingadvertisedasdrop-in
replacements for numerous applications. It should be
noted that, in the event of ordinary service to this
machine’s refrigeration system, only the refrigerantspecified on the affixed data label should be used.
The unauthorized use of alternate refrigerants will void
your compressor warranty . It will be the owner’s
responsibility to make this fact known to any technician
he employs.
It should also be noted that Taylor does not warrant the
refrigerant used in its equipment. For example, if the
refrigerant is lost during the course of ordinary service
to this machine, Taylor has no obligation to either
supply or provide its replacement either at billable or
unbillable terms. Taylor does have the obligation to
recommend a suitable replacement if the original
refrigerant is banned, obsoleted, or no longer available
during the five year warranty of the compressor.
Taylor will continue to monitor the industry and test
new alternates as they are being developed. Should a
new alternate prove, through our testing, that it would
be accepted as a drop-in replacement, then the above
disclaimer would become null and void. To find out the
current status of an alternate refrigerant as it relates to
your compressor warranty, call the local Taylor
Distributor or the Taylor Factory. Be prepared to
provide the Model/Serial Number of the unit in
question.

Section 6Operating Procedures
The Models 345, 346 and 355 contain two 7 quart (6.6
liter) freezing cylinders. The Model 349 contains four
7 quart (6.6 liter) freezing cylinders.
CAUTION: This unit is pressurized when
in operation. The control switch, located on the top
side of the control box must be in the OFF position until
the unit is completely assembled. No part should ever
be removed from the machine while it is in operation.
No parts should be removed until the control switch
has been turned to the OFF position and all pressure
has been relieved at the draw handle.
The syrup flow controls combine the two ingredients of
soda water and syrup, and send this combination to
the mix hoppers. As product is drawn, new product
from the hopper will flow through a mix feed tube down
into the freezing cylinder. The mix hopper is supplied
with 20 pounds of CO
product.
We begin our instructions at the point where the parts
are disassembled and laid out to air dry.
The following procedures will show you how to
assemble the parts into the freezer, sanitize them, and
prime the freezer with fresh product.

Step 4
Remove the right side panel and take the rear, white
drip pan to the sink for further cleaning.
Step 5
Remove the following parts: seals and o-rings from the
drive shafts, drive shaft seal bushings from drive shaft
seals, caps and springs from freezer doors, screws
and draw handle slides from freezer doors, pivot pins
from draw valves, draw valve handles from freezer
doors, draw valves from freezer doors, o-rings from
draw valves, prime plugs from freezer doors, o-rings
from prime plugs, o-rings and front bearings from
freezer doors, o-rings from mix hopper covers.
Discard all o-rings and replace them with new ones.
Note: To remove o-rings, use a single service towel to
grasp the o-ring. Apply pressure in an upward direction
until the o-ring pops out of its groove. With the other
hand, push the top of the o-ring forward. It will roll out
of the groove and can be easily removed. If there is
more than one o-ring to be removed, always remove
the rear o-ring first. This will allow the o-ring to slide
over the forward rings without falling into the open
grooves.
Step 6
Using a single service towel, wipe the lubricant off the
parts. Brush-clean all disassembled parts in the
cleaning solution. Make sure all lubricant and syrup is
removed. Place all the cleaned parts on a clean, dry
surface to air-dry.
Step 7
Wipe clean all the exterior surfaces of the freezer.

Section 7Important: O perator Checklist
During Cleaning and Sanitizing
ALWAYS FOLLOW LOCAL HEALTH CODES
Cleaning and sanitizing schedules are governed by
your State or local regulatory agencies and must be
followed accordingly. The following check points
should be stressed during the cleaning and sanitizing
operations.
WE RECOMMEND CLEANING AND SANITIZING
EVERY 90 DAYS.
T roubleshooting Bacterial Count
j 1. Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.
j 7. Clean and sanitize the syrup lines regularly to
prevent syrup residue build-up that would
restrict the proper flow of syrup.
j 8. On a regular basis, take a brix reading to assure
a consistent quality product.
Regular Maintenance Checks
j 1. Replace scraper blades that are nicked,
damaged or worn down.
j 2. Before installing the beater, be certain that the
scraper blades are properly attached over the
pins.
j 2. Use all brushes supplied for thorough cleaning.
The brushes are specially designed to reach all
product passageways.
j 3. Use the white bristle brush to clean the mix inlet
hole which extends from the mix hopper down
to the rear of the freezing cylinder.
j 4. Use the black bristle brush to thoroughly clean
the rear shell bearing located at the rear of the
freezing cylinder. Be sure there is a generous
amount of cleaning solution on the brush.
j 5. Using a screwdriver and a cloth towel, keep the
rear shell bearing and the female hex drive
socket clean and free of lubricant and product
deposits.
j 6. Properly prepare the cleaning and sanitizing
solutions. Read and follow the label directions
carefully. Too strong of a solution may damage
the parts and too weak of a solution will not do
an adequate job of cleaning or sanitizing.
j 3. Check the rear shell bearing for signs of wear
(excessive product leakage from the rear drip
pans to the front drip tray).
j 4. Dispose of o-rings or seals if they are worn, torn,
or fit too loosely, and replace with new ones.
j 5. Follow all lubricating procedures as outlined in
“Assembly”.
j 6. Check the condenser(s) for accumulation of dirt
and lint. Dirty condensers will reduce the
efficiency andcapacity ofthe machine.
Condensers should be cleaned monthly by
removing the poly--flo filter and cleaning it.
Remove the service panel and side panels to
exposethecondenser(s).Neveruse
screwdrivers or other metal probes to clean
between the fins.
If the place of business is to be closed during the winter
months, it is important to protect the freezer by
following certain precautions, particularly if the
building is subject to freezing conditions.
Disconnect the freezer from the main power source to
prevent possible electrical damage.
Your local Taylor Distributor can perform this service
for you.
Wrap detachable parts of the freezer such as the
beater, the scraper blades, the drive shaft, and the
freezer door. Place these parts in a protected, dry
place. Rubber trim parts and gaskets can be protected
by wrapping them with moisture-proof paper. All parts
should be thoroughly cleaned of dried mix or
lubrication which attract mice and other vermin.
Note: It is recommended that an authorized service
technician perform winter storage draining, to insure
all water has been removed. This will guard against
freezing and rupturing of the components.
