Electrical Connections

In the United States, this equipment is intended to be installed in accordance with the National 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. In all other areas of the world, equipment should be installed in accordance with the existing local codes. Please contact your local authorities.

FOLLOW YOUR LOCAL ELECTRICAL CODES!

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.

S 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.

S 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 the manufacturer, its service agent, or similarly qualified person, in order to avoid a hazard.

CAUTION: THIS EQUIPMENT MUST BE PROPERLY GROUNDED! FAILURE TO DO SO CAN RESULT IN SEVERE PERSONAL INJURY FROM ELECTRICAL SHOCK!

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.

S 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.

Beater Rotation

Beater rotation must be clockwise as viewed

looking into the freezing cylinder.

Note: The following procedures must be performed by an authorized Taylor service technician.

To correct the rotation on a three- phase unit, interchange any two incoming power supply lines at freezer main terminal block only.

To correct rotation on a single- phase unit, change the leads inside the beater motor. (Follow the diagram printedonthemotor.)

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).

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.

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.

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.

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.

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.

120611

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.

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 right and water adjustment is on the left.

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 T aylor 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 t o 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.
