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.
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.
Refrigeration Charging and Line
Construction
The dispensing unit is shipped with a refrigerant
holding charge that is sufficient enough to prevent
moisture contamination (8 oz./227 g. R404A). This
holding charge will become part of the total system
charge.
The condensing unit is shipped with the total amount
of refrigerant required for a typical installation of 75 ft.
or less with a single dispenser.
Set Up Procedures
Standard Fill Module
Step 1
Connect the product supply line to the 1/4” barbed
fitting on the fill module. Adjust the fill system pressure
to deliver product to the hopper at 1.5 to 2.5 oz. (42.5
to 70.9 g) per second. (Approximately 15 to 20 PSIG
[103- 138 kPa] for most products.)
Step 2
Lubricate, assemble, sanitize and prime the dispenser
as outlined in the Assembly section of this manual.
Step 3
Place the fill switch in the “ON” position. Allow the
product to fill the cylinder and the hopper until the mix
level float is satisfied.
Step 4
Place the power switch in the “AUTO” position.
Step 5
To observe the suction pressure, attach refrigeration
gauges to the suction access fitting in the dispenser.
Pressures should read approximately 32 psi. (221
kPa) for non- alcoholic application and 28 psi. (193
kPa) for alcoholic application.
Note: Connection to the condensing unit suction
access can give an improper reading.
Step 6
Allow the dispenser to run until the condensing unit
cycles off.
Step 7
If necessary, adjust viscosity to produce satisfactory
product. Adjustments are made by turning the
viscosity adjustment screw (located on the front panel)
clockwise for a thicker product or counterclockwise for
a thinner product.

4Models RD30/RC25To the Installer
Units Equipped With Post Mix Valve
Step 1
Connect syrup and water lines.
Note: Adjust the syrup supply pressure to maintain 60
PSIG. Water pressure minimum 40 PSIG, maximum
100 PSIG, may require regulated water supply.
Step 2
Turn the “FILL” switch in the front of the RD30 to the
“ON” position.
Step 3
Press and hold the area on the front of the post mix
valve marked “PUSH” to prime the fill system. Priming
is required until the B.I.B. switch and the float switch
are both satisfied. Priming is complete when product
will flow without pressing the “PUSH” button.
Step 4
To adjust either the syrup or water flow rate, turn the
flow adjustment screw clockwise to increase flow, or
counterclockwise to decrease flow. Adjust the screws
until the desired brix is obtained. The flow rate should
be 1.5 to 2.5 oz. (43 fl. ml.) per second.

Section 2 To the Operator
The freezer you have purchased has been carefully
engineered and manufactured to give you dependable
operation. The Taylor Model RD30/RC25, when
properly operated and cared for, will produce a
consistent quality product. Like all mechanical
products, this machine 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 Model RD30/RC25 will NOT eventually
compensate and correct for 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 all personnel
responsible for the equipment’s operation thoroughly
read this manual.
If you 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.
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.
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.

Sanitizing
Step 1
Fill System. Disconnect the product supply lines from
the mix delivery container. Prepare a pail of approved
100 PPM sanitizing solution (examples: 2- 1/2 gal. [9.5
liters] of Kay- 5Ror 2 gal. [7.6 liters] of
Stera- SheenR). USE WARM WATER AND FOLLOW
THE MANUFACTURER’S SPECIFICATIONS. Pour
the solution into a clean, empty mix delivery container.
Connect the container to the mix delivery line.
Figure 22
Step 2
Place the control switch in the “WASH” position. Press
the fill switch to activate the mix solenoid. The mix
solenoid will remain open until the mix level float switch
is satisfied. Drain sanitizer from the freezing cylinder
and repeat this procedure until full strength solution is
dispensed from the mix delivery container. Make sure
all sanitizer is removed from the fill system. Place the
fill switch in the “OFF” position and drain any remaining
solution from the freezing cylinder.
Figure 23
IMPORTANT! The unit must NOT be placed in AUTO
until all sanitizing solution has been removed from the
freezing cylinder and proper priming procedures have
been completed. Failure to follow this instruction may
result in damage to the freezing cylinder.
