Refrigerant
CAUTION! This machine contains fluorinated
greenhouse gases (F-Gas) to provide refrigeration using
a hermetically sealed circuit or within foam insulation.
This machine’s type of gas, quantity, Global Warming
Potential (GWP), and CO2tonnes equivalent information
is recorded on the machine’s data label. The refrigerant
used is generally considered nontoxic and
nonflammable. 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 approximately 80% will allow for
normal expansion.
CAUTION! Use only approved refrigerant
listed on the machine's data label or authorized through a
manufacturer's technical bulletin. The use of any other
refrigerant may expose users and operators 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
severe, apply ice packs and contact a physician
immediately.
NOTICE! 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.
IMPORTANT! Refrigerants and their
associated lubricants may be 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 machine is shipped with a refrigerant
holding charge that is sufficient enough to prevent

Setup Procedures
Standard Fill Module
1. Connect the product supply line to the 1/4 in. barbed
fitting on the fill module. Adjust the fill system
pressure to deliver product to the hopper at 1.5 oz. to 
2.5 oz. (42.5 g to 70.9 g) per second. (Approximately
15 PSIG to 20 PSIG [103 kPa to 138 kPa] for most
products.)
2. Lubricate, assemble, sanitize, and prime the
dispenser as outlined in “Assembly” on page 6-1.
3. Place the fill switch in the FILL position. Allow the
product to fill the cylinder and the hopper until the mix
level float is satisfied.
4. Place the control switch in the AUTO position.
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.
6. Allow the dispenser to run until the condensing unit
cycles off.
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.
Machines Equipped with Post Mix Valve
1. Connect syrup and water lines.
Note: Adjust the syrup supply pressure to maintain
60 PSIG. Water pressure between 40 PSIG and 100
PSIG may require regulated water supply.
2. Turn the fill switch in the front of the RD30 to the FILL
position.
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 BIB switch and the float switch
are both satisfied. Priming is complete when product
will flow without pressing the PUSH button.
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 oz. to 2.5 oz. (43 mL to 74 mL) per second.
Note: Both syrup and water flow adjustment screws
are located inside the post mix valve cover. Viewed
from the front, the syrup adjustment screw is on the

disassembly, go through these procedures together in
order to be properly trained and to make sure that all
personnel understand their role in using and maintaining
the machine.
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 a Taylor service technician.
Taylor reserves the right to deny warranty claims on units
or parts if unapproved 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.
IMPORTANT! If the crossed-out wheeled-bin

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/she 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 machine in question.
