Air Cooled Units
DO NOT obstruct air intake and discharge openings:
Air cooled units require 6” (152 mm) minimum air
space around all sides of the freezer to allow for
adequate air flow across the condenser(s). Failure to
allow adequate clearance can reduce the refrigeration
capacity of the freezer and possibly cause permanent
damage to the compressor.

Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided with
a hand shut--off valve on the two water inlet lines. On
the underside of the base pan, three 1/2” I.P.S. water
connections for inlet, outlet, and carbonator have been
provided for easy hook--up. 1/2” inside diameter water
lines should be connected to the machine. Flexible
lines are recommended, if local codes permit.
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.
There are two water “in” connections and one water
“out” line connection. DO NOT install a handshut--off valve 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.
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.

Beater Rotation
Refrigerant
In consideration of our environment, Taylor
proudly uses only earth friendly HFC refrigerants. The
HFC refrigerant used in this unit is R404A. This
refrigerant is generally considered non-toxic and
non-flammable, with an Ozone Depleting Potential
(ODP) of zero (0).
However, any gas under pressure is potentially
hazardous and must be handled with caution.
NEVER fill any refrigerant cylinder completely with
liquid. Filling the cylinder to approximately 80% will
allow for normal expansion.
Refrigerant liquid sprayed onto the skin may
cause serious damage to tissue. Keep eyes and skin
protected. If refrigerant burns should occur, flush
immediately with cold water. If burns are severe, apply
ice packs and contact a physician immediately .
Taylor reminds technicians to be cautious of
government laws regarding refrigerant recovery,
recycling, and reclaiming systems. If you have any
questions regarding these laws, please contact the
factory Service Department.
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: Thefollowingproceduresmustbe
performed by an authorized Taylor service
technician.
To correct the rotation on a three-- phase unit,
interchange any two incoming power supply lines at
freezer main terminal block only.
To correct rotation on a single--phase unit, change the
leads inside the beater motor. (Follow the diagram
printedonthemotor.)
Electrical connections are made directly to the
terminal block. The terminal block is provided in the
small junction box located behind the rear panel on the
bottom of the frame. (This does not apply to the Model
355.)

Remote Condenser Assembly
Units
Preparation
Recommended System Refrigerant Charge
Discharge/Liquid Line
Length
Up to 50 ft. (15 m.) line sets200 oz. / 567 kg.
Required Charge
Uncrate the condenser assemblies. After inspecting
them for damage, position them in the desired location.
Two remote condenser assemblies are required for
each freezer (one condenser per compressor).
Remote condensers require a minimum of 6”
(152 mm.) of air space on the rear and both sides.
This is required to allow for adequate air flow.
Failure to follow this instruction may cause poor
freezer performance and damage the equipment.
Refrigeration Charging and Line
Construction
Each condenser assembly is shipped with a refrigerant
holding chargesufficienttoprevent moisture
contamination (8 oz./227 g. HP62). This holding
charge will become part of the total system charge.
The condenser assemblies are shipped with the total
amount of refrigerant required for a typical installation
of 50 ft. (15 m.). For other installation configurations,
use the following chart for line sizing and for adding
required refrigerant.
50 -- 75 ft. (15 -- 23 m.)214 oz. / 607 kg.
(add 14 oz. / 40 kg.)
75 -- 100 ft. (23 -- 30 m.)228 oz. / 646 kg.
(add 28 oz. / 79 kg.)
Note: Maximum line length is 100 ft. (30 m.) T o meet
individual installation requirements, the lines must be
purchased and constructed locally.
Line Size
Liquid Line -- Requires 3/8” refrigerant grade copper
tubing (hard or soft).
Note: Insulating the liquid line is recommended if it is
exposed to high ambient conditions. This will reduce
heat accumulation and prevent the formation of flash
gas in the liquid line.
Discharge Line -- Requires 1/2” refrigerant grade
copper tubing (hard or soft).

Remote Condenser Installation
Step 1
Install refrigeration lines from the freezer to the
condenser assemblies. Do not create oil traps.
Remote Condenser Refrigeratio n
Connections
Connect the refrigerant line quick connect/disconnect
couplings (QD) to the mating QD couplings on the
condenser assembly by performing Steps 1 through 6.
When complete, repeat the instructions to connect the
couplings on the freezer.
Normally, any straight run of tubing must be supported
near each end of the run. Long runs require additional
supports. As a guide, 3/8” to 3/4” copper should be
supported every 5 ft. When changing directions, no
corner should be left unsupported. Supports should be
placed a maximum of 2 ft. in each direction from the
corner. If soft copper tube is used, make sure it is not
kinked or flattened. If hard drawn copper tubing is
used, use only long radius elbows.
Step 2
Braze the quick connect/disconnect couplings and
access tees on the freezer end of the refrigeration
lines. The couplings and access tees are supplied with
the freezer or condenser assembly.
Step 3
Brazethesuppliedquickconnect/disconnect
couplings on the condenser assembly end of the
refrigeration lines. The couplings are supplied with the
condenser assembly.
Note: Wrap a wet cloth around the brasscoupling
bodies to prevent heat damage to the seal.
Thoroughly clean and lubricate the mating surfaces of
the quick connect/disconnects.
Note: Use polyolester oil to lubricate the surfaces.
Step 3
Manually thread the coupling halves together to insure
proper mating of the threads.
Step 4
Using proper sized wrenches, tighten the coupling
halves until the round, flat surfaces of inner coupling
bodies completely depress one another.
Step 5
Once the flat surfaces are completely depressed,
tighten the couplings an additional 1/4 turn. This step
is necessary to insure that the knife edge of the seal
seats into the brass seat of the coupling halves,
forming a leak--proof joint (metal seal).
Step 4
Test the field constructed lines for leaks.
Step 5
Evacuate the field constructed refrigerant lines using
the access fittings brazed on the freezer end of the
refrigeration lines.
Step 6
When the evacuation process is complete, relieve the
vacuum with 4 oz. (113 g.) of HP62 refrigerant per line,
for a total of 8 oz. (227 g.) This procedure will prevent
moisture contamination during freezer and condenser
assembly connection and will complete the total
charge.

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.

Assembly
MAKE SURE THE CONTROL SWITCH IS
IN THE OFF POSITION. Failure to follow this
instruction may result in severe personal injury
from hazardous moving parts.
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube HP).
Step 1
Slide the o--ring into the first groove on the drive shaft.
Lubricate the groove, o--ring, the area where the boot
seal snaps onto the drive shaft, and the shaft portion
that comes in contact with the bearing on the beater
drive shaft. DO NOT lubricate the hex end of the
drive shaft.
Slide the seal over the shaft and groove until it snaps
into place. Pinch the boot seal and fill the inside portion
of the seal with 1/4” more lubricant.
The following procedures will show you how to
assemble the parts into the freezer, sanitize them, and
prime the freezer with fresh product.
Duplicate the following procedures, where they apply,
for the remaining f reezing cylinder(s).
If you are disassembling the machine for the first time
or need information to get to this starting point in our
instructions, turn to page 37 , “Disassembly” and start
there.

Step 2
Insert the drive shaft into the freezing cylinder, (hex
end first) and into the rear shell bearing, until the seal
fits securely over the rear shell bearing. Be certain the
drive shaft fits into the drive coupling without binding.
Step 4
Holding the blades in position, insert the beater
assembly into the freezing cylinder and slide it into
position over the drive shaft. Turn the beater slightly to
be certain that the beater is properly seated. When in
position, the beater will not protrude beyond the front
of the freezing cylinder.

Step 3
Check the scraper blade for any nicks or signs of wear.
If any nicks are present, replace the blade. If the blade
is in good condition, place the clip over the blade. Place
the rear scraper blade and clip over the single holding
pin on the beater (knife edge to the outside). Holding
the blade on the beater, turn it over and install the front
blade the same way.

Priming/Brixing
Step 1
Connect the syrup line to the Bag--in--Box (or the syrup
tank).
Step 2
Slowly open the syrup sampling valve and let it run into
a pail until all the sanitizer is removed and full strength
product is flowing. Do not open the valve so much that
the syrup line to the hopper is drained.
Allow the product to flow over the refractometer. The
brix reading should register 13 to 14. A reading higher
than this would cause a darker, richer product. The
refrigeration system would have to run longer to freeze
this excess syrup. A reading lower than this could
cause a freeze--up in the freezing cylinder because of
the excess water.
Figure 43
To adjust the brix, turn the adjustment screw located
in the service panel. Clockwise adjustments increase
the amount of syrup to water, and counterclockwise
adjustments decrease the amount of syrup to water.
Adjust the screw in small increments and check the
brix again.
Figure 42
Brix is the ratio of syrup to water which will directly
affect the quality and taste of the product. Brixing
should be done before priming the freezer and when
a change in syrup flavor has been made.

Disassembly
Step 1
Be sure the control switch is in the OFF position.
Step 2
Remove the following parts from the freezer and take
them to the sink for brush--cleaning: handscrews,
freezer doors, baffle assemblies, beater assemblies
and scraper blades, drive shafts, hopper covers, front
drip tray, and the splash shield.
Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution.
USEWARMWATERANDFOLLOWTHE
MANUFACTURER’S SPECIFICATIONS (examples:
Kay--5Ror Stera--SheenR). IMPORTANT: Follow
the label directions. Too STRONG of a solution can
cause parts damage, while too MILD of a solution will
not provide adequate cleaning. Make sure all brushes
provided with the freezer are available for brush
cleaning.
Step 2
Return to the freezer with a small amount of cleaning
solution. With a single service towel, wipe clean the
bearing surface. Brush--clean the rear shell bearings
at the back of the freezing cylinders with the black
bristle brush.
Step 3
Remove the rear drip pan. (Does not apply to the
Model 349.)
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 seals, caps and springs
from freezer doors, screws, draw handle slides and ice
buster from freezer doors, pivot pins from draw valves,
draw valve handles from freezer doors, draw valves
from freezer doors, o--rings from draw valves, 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
surfacetoair--dry.

Section 7Important: Operator 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 and capacity of the 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.
