To th e Installer

Air Cooled Units

DO NOT obstruct air intake and discharge openings:

Air cooled units require a minimum of 3” (76 mm) of clearance around all sides of the freezer and 12” (305 mm) on top to allow for adequate air flow across the condensers. Failure to allow adequate clearance can reduce the refrigeration capacity of the freezer and possibly cause permanent damage to the compressor.

Water Connections

(Water Cooled Units Only)

An adequate cold water supply must be provided with a hand shut--off valve. On the underside rear of the base pan, two 1/2” I.P.S. water connections for inlet and outlet have been provided for easy hook--up. The 1/2” inside diameter water lines should be connected to the machine. (Flexible lines are recommended, if local codes permit.) 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 shut--off 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

opentrapdrain.

FOLLOW YOUR LOCAL ELECTRICAL CODES!

Each unit requires one power supply for each data label on the unit. Check the data label on the freezer for fuse, circuit ampacity and other electrical specifications. Refer to the wiring diagram provided inside of the electrical box, for proper power connections.

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.

A back flow prevention device is required

on the incoming water connection side. Please

refer to the applicable National, State, and local codes for determining the proper configuration.

Electrical Connections

In the United States, this equipment is intended to be installed in accordance with the National Electrical Code (NEC), ANSI/NFPA70-1987. 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.

081216

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 3mm installed in the external installation.

S Appliances that are permanently connected

to fixed wiring and for which leakage currents may exceed 10 mA, particularly when disconnected, 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 authorized personnel to the local codes.

To th e Installer Model 8657

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.

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 the freezer main terminal block only.

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.

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.

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

Electrical connections are made directly to the terminal block provided in the splice boxes which are mounted behind the left and right upper side panels.

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.

Section 2 To the Operator

The freezer you have purchased has been carefully engineered and manufactured to give you dependable operation. The T aylor Model 8657, 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 Taylor freezer 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 study these procedures together in order to be properly trained and to make sure that no misunderstandings exist.

In the event you should require technical assistance, please contact your local authorized Taylor Distributor.

Note: Warranty is valid only if the parts are authorized Taylor parts, purchased from an authorized Taylor Distributor, and the required service work is provided by an authorized Taylor service technician. Taylor reserves the right to deny warranty claims on equipment or parts if non--approved parts or refrigerant were installed in the machine, system modifications were performed beyond factory recommendations, or it is determined that the failure was caused by neglect or abuse.

Note: Constant research results in steady improvements; therefore, information in this manual is subject to change without notice.

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 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

Model 8657

Important: To the Operator

Indicator Lights -“Mix Low”/“Mix Out”

When the “MIX LOW” light begins to flash, it indicates that the mix tank has a low supply of mix and should refilled as soon as possible. When the “MIX OUT” light begins to flash, it indicates that the mix tank has been almost completely exhausted and has an insufficient supply of mix to operate the freezer. At this time, the “STANDBY” and “AUTO” modes are locked out and the freezer shuts down. To initiate the refrigeration system, add mix to the tank and press “AUTO”. The freezer will automatically begin operation.

“Mix Ref”

When the word “MIX REF” is pressed, the light comes on, indicating that the mix cabinet refrigeration system is operating. The mix refrigeration is controlled by “MIX REF” found on the shake control panel. By pressing “AUTO” on either side of the freezer, the “MIX REF” function is automatically turned on. The “MIX REF” function cannot be cancelled unless the “AUTO” or “STANDBY” mode is cancelled first.

“Wash”

When the word “WASH” is pressed, thelight comes on, indicating beater motor operation. The “STANDBY” or “AUTO” modes must be cancelled first to activate the “WASH” mode.

“Auto”

When the word “AUTO” is pressed, the light comes on indicating that the main refrigeration system has been activated. In the “AUTO” mode, the “WASH” or “STANDBY” functions are automatically cancelled. The “MIX REF” function is automatically locked in to maintain the mix in the cabinet and the “PUMP” function is locked in to allow coaxial air/mix pump operation as required.

“Standby”

The Separate Hopper Refrigeration System (SHR) and the Cylinder Temperature Retention System (CTR) are standard features. The SHR incorporates the use of a separate small refrigeration system to maintain the mix in the reservoir to below 40_F(4.4_C) to assure bacteria control. The CTR works with the SHR to maintain a good quality product during long “No Sale” periods. It becomes necessary to warm the product in the freezing cylinder to approximately 35_F to 40_F(1.7_Cto4.4_C) to prevent overbeating and product breakdown.

To activate the SHR and CTR, press the word “STANDBY”. When the word “ST ANDBY” is pressed, the light comes on, indicating the CTR (Cylinder Temperature Retention System) has been activated. In the “STANDBY” mode, the “WASH”, “PUMP”, and “AUTO” functions are automatically cancelled. The “MIX REF” function is automatically locked in to maintain the mix in the cabinet.

To resume normal operation, press the word “STANDBY” to cancel the cycle, and then press the word “AUTO”. When the unit cycles off, the product in the freezing cylinder will be at serving viscosity.

“Pump”

When the word “PUMP” is pressed, the light comes on indicating that the coaxial air/mix pump will operate as required.

Note: An indicating light and an audible tone will sound whenever a mode of operation has been pressed. To cancel any function, press the word again and the light and mode of operation will shut off.

Thermistor Control -- Shake Side

The product temperature is adjusted by means of a thermistor control. Located just above the freezer door on the shake side is the thermistor control knob. Turning the adjusting knob clockwise will decrease product temperature. Turning the adjusting knob counterclockwise will increase the temperature. Each half turn will vary the temperature approximately two degrees. Allow the refrigeration system to cycle on and off 2 or 3 times before the adjusted temperature can be evaluated.

Adjustable Draw Handle -Soft Serve Side

Syrup Line Fitting With “Clean--Out” Feature

The soft serve side only features an adjustable draw handle to provide the best portion control, giving a better consistency quality to your product, and controlling costs. The draw handle should be adjusted to provide a flow rate of 5 to 7--1/2 oz. of product by weight per 10 seconds. T o increase the flow rate, turn the screw counterclockwise. To decrease the flow rate, turn the the screw clockwise. In addition, for purposes of sanitizing and rinsing, the flow rate can be increased by removing the pivot pin and placing the restrictive bar on the top. When drawing product

always have the restrictive bar on the bottom.

Liquid Valve Body Removal Tool

This tool was designed to help remove the valve body from the pump cylinder. Remove the suction line, flare line, retaining pin and mix inlet fitting from the pump cylinder. Turn the coaxial air/mix pump assembly upside down. Insert the curved end under the edge of the valve body and pull down, as shown in the illustration below.

During daily operation, hardened syrup could get lodged in the syrup line fitting. T o clear the syrup line of restrictions, follow these steps:

Prepare a mix pail with cleaning solution.

Disconnect the restricted syrup line at the syrup tank and at the freezer door.

Place the syrup sampler on the syrup line fitting at the freezer door and press into an empty pail. This will relieve any pressure that might be in the syrup line. Unscrew the cap on the back of the syrup line fitting and pull the cap, spring, and valve out.

Rinse the syrup line fitting, cap, spring, and valve in the pail of cleaning solution.

Once thoroughly rinsed of any restrictions, place the valve, spring, and cap back inside the syrup line fitting and tighten the cap securely.

Reconnect the syrup line fitting at the syrup tank.

Calibrate the syrup flow. (Refer to page 38.)

This will enable you to easily pull the valve body out of the pump cylinder. To remove the piston, push down from the top end of the pump cylinder. To prevent breakage, do not allow the piston to fall free.

Section 6 Operating Procedures

The Model 8657 is a combination shake and soft serve freezer. It is recommended that these operating procedures be followed closely so that the operating parts for the shake side will not be confused or interchanged with the operating parts for the soft serve side. Parts trays are provided to help keep the various parts separate.

We begin our instructions at the point where we enter the store in the morning and find the parts disassembled and laid out to air dry from the previous nights cleaning.

The following procedures will show you how to assemble the parts into the freezer, sanitize them, and prime the freezer with fresh mix in preparation to serve your first portion.

If you are disassembling the machine for the first time or need information to get to this starting point in our instructions, turn to page 42 “Disassembly” and start there.

Freezing Cylinder Assembly -Shake Side

Note: When lubricating parts, use an approved food

grade lubricant (example: Taylor Lube).

Step 1

Install the drive shaft. Lubricate the groove and shaft portion on the beater drive shaft with the square end. Slide the seal onto the shaft and over the groove until it snaps into place. Do not lubricate the square end of the drive shaft. Fill the inside portion of the seal with 1/4” more lubricant and evenly lubricate the end of the seal that fits onto the rear shell bearing.

Install the drive shaft through the rear shell bearing in the freezing cylinder and engage the square end firmly into the gear box coupling. Be sure the drive shaft fits into the drive coupling without binding.

Step 2

Install the beater assembly. First check the scraper blades for any nicks or signs of wear. If any nicks are present or if the blade is worn, replace both blades. If the blades are in good condition, place the rear scraper blade over the rear holding pin on the beater.

Figure 3

Note: The scraper blade must fit securely over the pin

Operating Procedures Model 8657

to prevent costly damage.

Holding the rear blade on the beater, slide it into the freezing cylinder half way. Install the front scraper blade over the front holding pin. Slide the beater assembly the rest of the way into the freezing cylinder.

Figure 4

Make sure the beater assembly is in position over the drive shaft. Turn the beater slightly to be certain that the beater is properly seated. When in position, the beater will not protrude beyond the front of the freezing cylinder.

Figure 6

Insert the prime plug into the hole at the top of the freezer door and push down.

Step 3

Assemble the freezer door. Place the freezer door gasket into the groove on the back of the freezer door. Slide the front bearing onto the bearing hub so the flanged edge is against the door. Do not lubricate the gasket or bearing.
