Electrical Code (NEC), ANSI/NFPA 70-1987. The
purpose of the NEC code is the practical
safeguarding of persons and property from hazards
arising from the use of electricity. This code contains
provisions considered necessary for safety.
Each unit requires one power supply for each data
label on the unit. Check the data label(s) on the
freezer for branch circuit overcurrent protection or
fuse, circuit ampacity, and other electrical
specifications.
Refer to the wiring diagram provided inside of the
electrical box, for proper power connections.
DO NOT operate this freezer with larger
fuses than specified on the unit data label. Failure to
follow this instruction may result in electrocution or
damage to the machine.
This unit is provided with an equipotential
grounding lug that is to be properly attached to the
rear of the frame by the authorized installer. The
installation location is marked by the equipotential
bonding symbol (5021 of IEC 60417-1) on both the
removable panel and the equipment's frame.
Stationary appliances which are not equipped with a
power cord and a plug or another device to
disconnect the appliance from the power source
must have an all-pole disconnecting device with a
contact gap of at least 3 mm installed in the external
installation.
Appliances that are permanently connected
to fixed wiring and for which leakage currents may
exceed 10 mA, particularly when disconnected or
not used for long periods, or during initial installation,
shall have protective devices such as a GFI, to
protect against the leakage of current, installed by
the authorized personnel to the local codes.
Supply cords used with this unit shall be
oil-resistant, sheathed, flexible cable not lighter than
ordinary polychloroprene or other equivalent
synthetic elastomer-sheathed cord (Code
designation 60245 IEC 57) installed with the proper
cord anchorage to relieve conductors from strain,
including twisting, at the terminals and protect the
insulation of the conductors from abrasion.
If the supply cord is damaged, it must be replaced
by an authorized Taylor service technician in order
to avoid a hazard.
CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY

Water Connections
(Water Cooled Units, Only)
An adequate cold water supply must be provided
with a hand shut-off valve. On the underside of the
base pan or on the right side, two 3/8” I.P.S. water
connections for inlet and outlet are provided for easy
hook-up. ½” inside diameter water lines should be
connected to the machine.
Flexible hose sets are recommended, if local codes
permit. In Europe, hose sets for connection of
appliances to the water mains must comply with the
international IEC 61770 standard.
The automatic water valve setting of the unit (high
side) is to be set at 250 to 260 PSIG (17.2 to 17.9
Bar). The recommended low side setting is 38 to 39
PSIG (2.6 to 2.7 Bar). Please consult the automatic
water valve tag connected to the unit to verify.
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 will be only one water “in” and
one water “out” connection.
DO NOT install a hand shut-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 open trap drain.
A back siphon device must be installed to prevent
back siphonage of non-potable water into the water
system.
Refrigerant
In consideration of our environment, Taylor
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.
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 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.
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 freezer you have purchased has been carefully
engineered and manufactured to give you
dependable operation. When properly operated and
cared for, it 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 your
equipment.
Your Taylor freezer will NOT eventually compensate
for and correct any errors during the set-up or filling
operations. Thus, the initial assembly and priming
procedures are of extreme importance. It is strongly
recommended that personnel responsible for the
equipment's operation review these procedures in
order to be properly trained and to make sure that
no misunderstandings exist.
If you require technical assistance, please contact
your local authorized Taylor Distributor.
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.
Note: Constant research results in steady
improvements; therefore, information in this
manual is subject to change without notice.
If the crossed out wheeled bin symbol is
affixed to this product, it signifies that this product is
compliant with the EU Directive as well as other
similar 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 product to
the appropriate collection facility, as specified by
your local code.
For additional information regarding applicable local
laws, please contact the municipal facility and/or
local 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.
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 machine’s refrigeration
system, only the refrigerant specified 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 know 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.

5
Model 390 Tim Hortons To the Operator
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.

Model 390 Tim Hortons Operating Procedures
131009
Section 6 Operating Procedures
The Model 390 freezer is designed to produce slush
product at the desired thickness. This unit has a 7
quart freezing cylinder.
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 brush cleaning.
These opening procedures will show you how to
assemble these parts into the freezer, sanitize them,
and prime the freezer with fresh mix in preparation
to serve your first portion.
If you are disassembling the machine for the first
time or need information to get to this point in our
instructions, turn to page 20, “Disassembly”, and
start there.
Assembly
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).
Step 1
Lubricate the groove on the drive shaft and slide the
o-ring in place. Lubricate the o-ring and shaft
portion that comes in contact with the bearing. DO
NOT lubricate the square end of the drive shaft.
Lubricate the boot seal groove, and slide the boot
seal over the shaft and groove until it snaps into
place. Fill the inside portion of the seal with 1/4”
more lubricant and evenly lubricate the end of the
seal that fits onto the rear shell bearing.
Figure 5
Note: Do not install the boot seal inside out.
Step 2
Insert the beater drive shaft into the rear shell
bearing and engage the square end firmly into the
female socket of the drive unit. Be certain that the
drive shaft fits into the drive coupling without
binding.
Figure 6
Step 3
Check the scraper blades for any nicks or signs of
wear. If any nicks are present or if the blade is worn,
replace both blades.
Step 4
If the blades are in good condition, place the rear
scraper blade over the rear holding pin (knife edge
to the outside). Holding the blade on the beater, turn
it over and install the front blade the same way.
Figure 7

14 Model 390 Tim HortonsOperating Procedures
110503
Step 5
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 it is in position, the beater will not protrude
beyond the front of the freezing cylinder.

Step 6
Install the white plastic guide bearing on the short
end of the torque rotor. Slide the o-ring into the
groove on the long end of the torque rotor and
lubricate the o-ring. Do not lubricate the guide
bearing.
Figure 9
Step 7
Insert the torque rotor end with the guide bearing
into the pilot hole in the center of the drive shaft. The
hole in the torque rotor shaft should be rotated to the
12 o'clock position.
Step 8
Assemble the freezer door with the “Ice Buster”
(door spout clearing device). To assemble the door
with the ice buster, install the o-rings on the draw
valve and lubricate.
Figure 10
Step 9
Insert the draw valve into the door, leaving
approximately 1/2” of the valve sticking out the top
of the door.

Step 10
Rotate the draw valve so the flats on the top of the
draw valve are perpendicular to the door face.
Figure 12
Step 11
Insert the ice buster through the door spout and into
the slot located just above the lower o-ring.
Figure 13
Step 12
With the ice buster in place, rotate the draw valve to
allow installation of the draw handle. This will lock
the ice buster in place. Install the draw handle pin,
and close the draw valve by moving the handle to
the left.
Figure 14
Step 13
Place the o-ring onto the prime plug and lubricate.
Figure 15
Step 14
Screw the prime plug into position on the front of the
door.

Step 15
Place the rounded side of the large rubber gasket
into the groove on the back side of the freezer door.
Slide the white plastic front bearing onto the bearing
hub, making certain that the flanged end of the
bearing is resting against the freezer door. Do not
lubricate the door gasket or front bearing.
Figure 17
IMPORTANT: The door gasket must be installed
with the rounded side in the groove on the back
side of the door. If the door gasket is incorrectly
installed, mix can leak from the freezing cylinder.
Figure 18
Step 16
Place the front end of the torque rotor into the hole
in the center of the door. Position the door onto the
four studs on the front of the freezing cylinder. Raise
the lever that rests on top of the draw valve and
push the door into place. Install the four handscrews
onto the studs and tighten them equally in a
criss-cross pattern to insure the door is snug. DO
NOT over-tighten the handscrews.
Note: Be sure to lift the draw lever when placing the
door into position. Failure to do so may cause a
failure to the related components.
Figure 19
Note: If the freezer door does not go into place
easily, position the open end of the beater assembly
in the 11 o'clock position.
Step 17
Position the torque arm by inserting it through the
slot in the torque switch arm and down into the hole
in the torque rotor which protrudes from the door.
Verify proper installation by moving the torque rotor
back and forth to be sure it moves freely and easily.
