Beater Rotation
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
To correct the rotation on a three-phase unit,
interchange any two incoming power supply lines at
unit's main terminal block only.
To correct rotation on a single-phase unit, change
the leads inside the beater motor. (Follow the
diagram printed on the motor.)
Electrical connections are made directly to the
terminal block provided in the main control box
located under the upper left side panel on the
countertop unit, or behind the service panel on the
console units.
It is recommended that beater rotation be performed
by an authorized Taylor service technician.
Refrigerant
In consideration of our environment, Taylor
uses only 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.
Use only R404A refrigerant that conforms
to the AHRI standard 700 specification. The use of
any other refrigerant may expose users and
operators to unexpected safety hazards.
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 aware of
and in compliance with local government laws
regarding refrigerant recovery, recycling, and
reclaiming systems. For information regarding
applicable local laws, please contact your local
authorized Taylor distributor.
WARNING: R404A refrigerant used in
conjunction with polyolester oils is extremely
moisture absorbent. When opening a refrigeration
system, the maximum time the system is open must
not exceed 15 minutes. Cap all open tubing to
prevent humid air or water from being absorbed by
the oil.

Section 2 To the Operator
The unit you have purchased has been carefully
engineered and manufactured to give you
dependable operation.
This unit, when properly operated and cared for, will
produce a consistent quality product. Like all
mechanical products, it will require cleaning and
maintenance. A minimum amount of care and
attention is necessary if the operating procedures
outlined in this manual are followed closely.
This Operator's Manual should be read
before operating or performing any maintenance on
the unit.
Your Taylor unit will NOT compensate for and/or
correct any errors made during the set-up or filling
operations. Thus, the initial assembly, set-up, and
priming procedures are of extreme importance. It is
strongly recommended that all personnel
responsible for the unit's operation, including
assembly and disassembly, go through these
procedures together in order to be properly trained
and to make sure that all understand their role in
using and maintaining the unit.
In the event you should require technical assistance,
please contact your local authorized Taylor
Distributor.
Note: Your Taylor warranty is valid only if the parts
are authorized Taylor parts, purchased from the
local authorized Taylor Distributor, and only if all
required service work is provided by an authorized
Taylor service technician. Taylor reserves the right
to deny warranty claims on units or parts if
non-Taylor approved parts or incorrect refrigerant
were installed in the unit, system modifications were
performed beyond factory recommendations, or it is
determined that the failure was caused by abuse,
misuse, neglect, or failure to follow all operating
instructions. For full details of your Taylor Warranty,
please see the Limited Warranty section in this
manual.
If the crossed out wheeled bin symbol is
affixed to this unit, it signifies that this unit is
compliant with the EU Directives as well as other
similar end of life legislation in effect after August
13, 2005. Therefore, it must be collected separately
after its use is completed, and cannot be disposed
as unsorted municipal waste.
The user is responsible for returning the unit to the
appropriate collection facility, as specified by your
local code.
For additional information regarding applicable local
disposal laws, please contact the municipal waste
facility and/or local authorized Taylor distributor.
Compressor Warranty Disclaimer
The refrigeration compressor(s) on this unit are
warranted for the term stated in the Limited
Warranty section in this manual. 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
refrigerants are being advertised as drop-in
replacements for numerous applications. It should
be noted that in the event of ordinary service to this
unit's refrigeration system, only the refrigerant
specified on the affixed data label should be
used. The unauthorized use of alternate refrigerants
will void your Taylor compressor warranty. It is the
unit 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 unit, Taylor has no obligation to either
supply or provide replacement refrigerant either at
billable or unbillable terms. Taylor will recommend a
suitable replacement if the original refrigerant is
banned, obsoleted, or no longer available during the
five (5) year Taylor warranty of the compressor.

5
Model 793 To the Operator
From time-to-time Taylor may test new refrigerant
alternates. Should a new refrigerant alternate prove,
through Taylor's testing, that it would be accepted as
a drop-in replacement for this unit, then the
disclaimer in this “Compressor Warranty Disclaimer”
section will not apply to the use of the alternate
refrigerant approved by Taylor.
To find out the current status of an alternate
refrigerant as it relates to your compressor warranty,
call Taylor or your local authorized Taylor distributor.
Be prepared to provide the Model/Serial Number of
the unit in question.
Note: Continuing research results in steady
improvements; therefore, information in this
Operator Manual is subject to change without
notice.

Air Tube
Figure 5
After priming the unit, lubricate the o-rings on the
end of the air tube that has the small hole on the
side. Install that end of the air tube into the mix inlet
hole. Every time the draw handle is raised, new mix
and air from the hopper will flow down into the
freezing cylinder. This will keep the freezing cylinder
properly filled and maintain overrun.

14 Model 793Operating Procedures
Section 6 Operating Procedures
The Model 793 stores mix in a hopper. The mix
flows by gravity through an air tube into the freezing
cylinder. The unit has two 3.4 quart (3.2 liter)
capacity freezing cylinders and two 14 quart (13.2
liter) mix hoppers.
We begin our instructions at the point where we
enter the store in the morning and find the parts
disassembled and laid out to air dry from the
previous night's cleaning.
The opening procedures in this section will show you
how to assemble these parts into the unit, sanitize
them, and prime the unit with fresh mix in
preparation to serve your first portion.
If you are disassembling the unit for the first time or
need information to get to this starting point in our
instructions, turn to page 22, “Disassembly”, and
start there.
Assembly
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).
MAKE SURE POWER SWITCH IS IN THE
“OFF” POSITION! Failure to follow this instruction
may result in severe personal injury from hazardous
moving parts.
Step 1
Lubricate the groove and shaft portion that comes in
contact with the bearing on the beater drive shaft.
Slide the seal over the shaft and groove until it
snaps into place. DO NOT lubricate the hex end of
the drive shaft. Fill the inside portion of the seal with
1/4” more lubricant and lubricate the flat side of the
seal that fits onto the rear shell bearing.
Figure 6
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. Engage the
hex end firmly into the drive coupling. Be sure the
drive shaft fits into the drive coupling without
binding.

Step 3
Take one of the scraper blades and slip it under the
hook at the front of the beater. Wrap the blade
around the beater, following the helix and pushing
the blade down onto the helix as you wrap. At the
back end of the beater, slip the blade under the
hook. Repeat this step for the second scraper
blade.
Figure 8
Step 4
Holding the beater securely, slide the beater one
third of the way into the freezing cylinder. Looking
into the freezing cylinder, align the hole at the rear of
the beater with the flats on the end of the drive
shaft.
Figure 9
Step 5
Slide the beater the remainder of the way into the
freezing cylinder and over the end of the drive shaft.
The beater should fit snugly, but not so tightly that
the beater cannot be turned slightly to engage the
drive shaft. If the beater slides in too easily with little
or no resistance, there will not be enough force
against the beater to hold the blades in place. If this
is the case, contact your authorized Taylor service
technician.
Repeat steps 1 - 5 for the other side of the unit.
Step 6
Place the large rubber gaskets into the grooves on
the back side of the freezer door.
Step 7
Slide the white plastic front bearings over the baffle
rods onto the bearing hubs, making certain that the
flanged end of the bearing is resting against the
freezer door.
Note: Do not lubricate the gaskets or the front
bearings.

Step 8
Insert the baffle rods through the opening in the
beaters and seat the door flush with the freezing
cylinder. With the door seated on the freezer studs,
install the handscrews. The short handscrews go on
the bottom and the long handscrews go on the top.
Tighten equally in a crisscross pattern to ensure the
door is snug.
