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.

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. For other installation configurations, use the following chart for line sizing and for adding required refrigerant.

NEVER fill any refrigerant cylinder completely with liquid. Filling the cylinder to approximately 80% will allow for normal expansion.

Use only R134a refrigerant that conforms to the AHI 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.

Models RD30/RC25To the Installer

Installation

Step 1

Install refrigeration lines from the dispenser to the condensing unit. Do not create oil traps.

Note: For proper oil return, installation of horizontal suction lines are to be sloped downward in the direction of the condensing unit. The slope must be a minimum 1/4” (.64 cm.) angle per 10 ft. (3.048 m.) of line length.

Step 5

Evacuate the field constructed refrigerant lines using the access fittings brazed on the condensing end of the refrigeration lines.

Step 6

When the evacuation process is complete, relieve the vacuum with 4 oz. (113 g.) of HP62 refrigerant per line, for a total of 8 oz. (227 g.) This procedure will prevent moisture contamination during dispenser and condensing unit connection and complete the total charge.

Refrigeration Connections

Connect the refrigerant line quick connect/disconnect couplings to the mating quick connect/disconnect couplings on the dispensing and condensing unit.

Step 1

Remove the shipping caps from the quick connect/disconnect coupling on the dispensing unit.

Step 2

Thoroughly clean and lubricate the mating surfaces of the quick connect/disconnects.

Note: Use polyolester oil to lubricate the surfaces.

Figure 1

Normally, any straight run of tubing must be supported near each end of the run. Long runs require additional supports. As a guide, 3/8” to 3/4” copper should be supported every 5 ft. When changing directions, no corner should be left unsupported. Supports should be placed a maximum of 2 ft. in each direction from the corner. If soft copper tube is used, make sure it is not kinked or flattened. If hard drawn copper tubing is used, use only long radius elbows.

Step 2

Braze the supplied quick connect/disconnect couplings on the dispenser end of the refrigeration lines. Couplings are supplied with the dispenser.

Step 3

Braze the quick connect/disconnect couplings and access tees on the condensing unit end of the refrigeration lines. Couplings and access tees are supplied with the unit.

Note: Wrap a wet cloth aroundthe brasscoupling bodies to prevent heat damage to the seal.

Step 3

Manually thread the coupling halves together to insure proper mating of the threads.

Step 4

Using proper sized wrenches, tighten the coupling halves until the round, flat surfaces of inner coupling bodies completely depress one another.

Step 5

Once the flat surfaces are completely depressed, tighten the couplings an additional 1/4 turn. This step is necessary to insure that the knife edge of the seal seats into the brass seat of the coupling halves, forming a leak--proof joint (metal seal).

Step 4

Test the field constructed lines for leaks.

Models RD30/RC25 To the Installer

Figure 2

Step 6

Check all connections for leaks.

Step 7

Insulate all exposed suction line tubing and fittings.

Step 8

Set the pump down switch located in the condensing unit. For indoor condensing unit application:

Set cut in at 30 PSIG (207 kPa). Set cut out at 5 PSIG (34 kPa).

For outdoor condensing unit application:

Set cut in at 20 PSIG (138 kPa). Set cut out at 0 PSIG (0 kPa).

Pump down pressure readings are to be taken at the refrigeration line access fittings at the condensing unit.

Step 6

Allow the dispenser to run until the condensing unit cycles off. Verify the proper pump down pressure switch setting. See Step 8 of “Refrigeration Connections” (page 6).

Note: Pump down pressure readings are to be taken at the refrigeration line access fittings near the condensing unit.

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.

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.

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.

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 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 T aylor Factory. Be prepared to provide the Model/Serial Number of the unit in question.
