Disconnect Switch
If the machine has no plug, a separate disconnect switch
must be installed, or another alternate means to
disconnect power must be implemented.
Water Connections
Water-Cooled Machines, Only
An adequate cold water supply must be provided with a
hand shut-off valve. The water inlet and drain
connections are located on the right side or the underside
of the base. These connections are either 3/8 in. or 
1/2 in. FTP, depending on the model of the machine.
(Refer to “Model Specifications.”)
Flexible lines are recommended, if local codes permit. In
Europe, hose sets for connection of appliances to the
water mains must comply to the International IEC 61770
standard.
The water expansion valve setting should be set at 
255 PSIG (1758 kPa).
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 shutoff 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.
IMPORTANT! A backflow prevention device is
required on the incoming water connection side. Please
see the applicable national, state, and local codes for
determining the proper configuration.
Refrigeration
CAUTION! In consideration of our environ-
ment, Taylor uses only earth-friendly HFC refrigerants.
The HFC refrigerant used in this machine is R404A. This
refrigerant is generally considered nontoxic and nonflam-
mable, with an ozone-depleting potential (ODP) of zero
(0). However, any gas under pressure is potentially haz-
ardous 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.
CAUTION! Use only R404A refrigerant that
conforms to the AHRI standard 700 specification. The
use of any other refrigerant may expose users and oper-
ators to unexpected safety hazards.
WARNING! Refrigerant liquid sprayed onto
the skin may cause serious damage to tissue. Keep eyes
and skin protected. If refrigerant burns should occur,
flush the area immediately with cold water. If burns are

IMPORTANT! R404A refrigerant used in con-
junction with polyolester oils is extremely moisture absor-
bent. 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.
Main Compressor:
Air-cooled machines: 40 oz. (1,134 g) of R404A.
Water-cooled machines: 38 oz. (1,077 g) of R404A.
Gear Alignment and Rear Shell Bearing
1. Make sure the drive shaft(s) can easily slide in and
out of the female socket on the gear unit(s).
2. If a drive shaft is binding, the gear unit could be out of
alignment (loose). Check the bolts on the gear unit to
make sure they are tight.
3. Inspect the rear shell bearing for tightness. Make
sure the locking tab has been folded over to prevent
the nut from loosening.

toppings. Place the topping pump in the heated syrup
jar. Sanitize the ladle and place it in the room
temperature jar.
Environmental Notices
CAUTION! In consideration of our
environment, Taylor uses only earth-friendly HFC
refrigerants. The HFC refrigerant used in this machine is
R404A. This refrigerant is generally considered nontoxic
and nonflammable, 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.
IMPORTANT! If the crossed-out waste
container 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 delivering 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.
NOISE LEVEL: Airborne noise emission does not
exceed 78 dB(A) when measured at a distance of 
1.0 meter from the surface of the machine at a height of
1.6 meters from the floor.

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 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 owners’ responsibility to make this fact known to any
technicians they employ.
It should 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, call the local Taylor distributor or the
Taylor factory. Be prepared to provide the model/serial
number of the machine in question.

= STANDBY
Power Switch
When placed in the ON position, the power switch allows
control panel operation.
Liquid Crystal Display (LCD)
The liquid crystal display (LCD) is located on the front
control panel. During normal operation, the display is
blank. The display is used to show menu options and
notifies the operator if a fault is detected. On international
models, the display will indicate the temperature of the
mix in the hopper.
Indicator Lights
MIX LOW - When the Mix Low indicator is
illuminated, the mix hopper has a low supply of mix and
should be refilled as soon as possible.
MIX OUT - When the Mix Out indicator is illuminated,
the mix hopper has been almost completely exhausted
and has an insufficient supply of mix to operate the
freezer. At this time, the Auto mode is locked out and the
freezer will be placed in the Standby mode. To initiate the
refrigeration system, add mix to the mix hopper and
touch the Auto button .The freezer will automatically
begin operation.
Adjustable Draw Handle
This machine features an adjustable draw handle to
provide the best portion control, giving a better,
consistent quality to your product and controlling costs.
The draw handle should be adjusted to provide a flow
rate of 5 oz. to 7-1/2 oz. (142 g to 213 g) of product by
weight per 10 seconds. To increase the flow rate, turn
the screw clockwise, and counterclockwise to
decrease the flow rate. (See Figure 1-4.)
