Model PH90 To th e Installer

a water jet could be used. Failure to follow this instruction may result in serious electrical shock.

081210

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 to allow for adequate air flow across the condensers. Install the deflector provided to prevent recirculation of warm air. Failure to allow adequate clearance can reduce the refrigeration capacity of the freezer and possibly cause permanent damage to the compressors.

Water Connections

(Water Cooled Units Only)

An adequate cold water supply must be provided with a hand shut--off valve. On the rear of the unit, two 1/2” I.P.S. water connections for inlet and outlet have been provided for easy hook--up. 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.

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.

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.

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.

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.

081210

Model PH90To th e Installer

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 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 diagram printed on motor.)

Electrical connections are made directly to the terminal block. The terminal block is provided in the main control box located behind the panel in the rear of the syrup compartment.

Refrigerant

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.

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.

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 PH90, 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 PH90 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 personnel responsible for the equipment’s operation, both assembly and disassembly, study these procedures 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.

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 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 .

The Taylor Company 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.

Power Switch

Liquid Crystal Display

The power switch is located under the control panel on the left hand side of the unit. When placed in the ON position, the power switch allows Softech panel operation.

Indicator Lights

Mix Low -- When the MIX LOW light begins to flash,

it indicates the mix hopper has a low supply of mix and should be refilled as soon as possible. The word “LOW” will also display on the LCD indicator next to the word “MIX”.

Mix Out -- When the MIX OUT light begins to flash, it indicates the mix hopper has been almost completely exhausted and has an insufficient supply of mix to operate the freezer. The word “OUT” will also display on the LCD indicator next to the word “MIX”. At this time the AUTO mode is locked out and the freezer will be placed in the STANDBY mode. To initiate the refrigeration system, add mix to the mix hopper and press the AUTO keypad. The freezer will automatically begin operation.

Heat Mode -- When the HEAT MODE light is flashing, it indicates that the freezer is in the process of a heat cycle.

Clean Manually -- When the CLEAN MANUALLY light is flashing, it indicates that the machine must be disassembled and brush cleaned within 24 hours.

When all four indicator lights are flashing, this signifies a locked condition. When MIX LOW and MIX OUT lights are flashing only, this signifies an unlocked condition.

Located on the front control panel is the Liquid Crystal Display (LCD). The LCD is used to show what mode of operation the freezer is in and whether or not there is sufficient mix.

Heater Switch

The heater switch is located under the control panel on the right hand side of the unit. When placed in the ON position, the heater switch controls power to the heated syrup topping rail.

Reset Mechanism

The reset buttons are located in the syrup compartment, behind the syrup tanks. There is one for each side of the freezer.

The reset mechanism protects the beater motor from an overload condition. Should an overload occur, the reset mechanism will trip. To properly reset the freezer, place the power switch in the OFF position. Press the reset button firmly. Turn the power switch to the ON position. Clear the fault. Press the WASH keypad and observe the freezer’s performance. Open the side access panel to check if the beater motor is turning the drive shaft in a clockwise (from the operator end) direction without binding.

Flavor Selector Keypad

Four shake flavors are offered from the Model PH90 freezer: chocolate, strawberry, vanilla (unflavored product), and an optional flavor. Press the desired shake flavor keypad and open the draw valve. Product and syrup will automatically blend to produce the chosen flavor.

Do not use metal objects to press the reset button. Failure to follow this instruction may result in electrocution.

If it is turning properly, press the WASH keypad to cancel the cycle. Press the AUTO keypad on both sides of the machine to resume normal operation. If the freezer shuts down again, contact service technician.

Model PH90Important: To the Operator

Adjustable Draw Handle

The soft serve side of the freezer features an adjustable draw handle to provide the best portion control, giving a better, consistent 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. To INCREASE the flow rate, turn the screw COUNTERCLOCKWISE, and CLOCKWISE to DECREASE the flow rate. 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.

IMPORTANT: Once the draw rate is

set, tighten the lock nut with a wrench.

Operating Screen Descriptions

After the safety timeout has been completed, and the power switch is OFF, one of the following screens is displayed.

The first screen is displayed if the machine is not in a brush clean state. If any of the requirements for a brush clean have not been met, the time displayed will remain at 5:00 minutes. When all the requirements for a brush cleaning are met, and the five minutes expire, the screen will change to the second screen, which is the standard power switch OFF screen.

Section 6 Operating Procedures

Equipment Set Up

Evaluate the condition of lights and screen messages (Hard Lock or Soft Lock, etc.) before performing opening procedures. If all four LED’s on the front of the unit are lit, the unit is locked. (See Figure 1.)

Figure 1

Freezing Cylinder Assembly -Shake Side

Note: When lubricating parts, use an approved food

grade lubricant (example: Taylor Lube HP).

Figure 2

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. (See Figure 3.)

MAKE SURE POWER SWITCH IS IN THE

“OFF” POSITION. Failure to do so may cause injury

from hazardous moving parts, or electrocution.

Be certain your hands are sanitized before assembling the freezer.

With the parts tray available for the shake side:

Step 1

To install the drive shaft, lubricate the groove and shaft portion that comes in contact with the bearing on the beater drive shaft. Slide the seal over the shaft and 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. (See Figure 2.)

Model PH90 Operating Procedures

Figure 3

Check scraper blades for any nicks or signs of wear. If any nicks are present, replace the blades.

Note: Scraper blades should be replaced every 6 months.

If blades are in good condition, place each scraper blade over the holding pins on the beater assembly. (See Figure 4.)

Step 2

Assemble the freezer door. Place the freezer door o--ring into the groove on the back of the freezer door. DO NOT lubricate the o--ring. Lubricate the outside diameter of the front bearing. Slide the front bearing into the door hub. (See Figure 6.)

Figure 4

Note: The holes in the scraper blade must fit over the pins to prevent damage.

Holding the blades on the beater assembly, insert the drive shaft of the beater assembly through the rear shell bearing in the freezing cylinder and engage the square end firmly into the drive coupling. (See Figure 5.)

Note: When properly seated, the beater will not protrude beyond the front of the freezing cylinder.

Figure 6

Step 3

Install the freezer door. Position the freezer door on the 4 studs on the front of the freezing cylinder. Install the handscrews. Tighten equally in a criss--cross pattern to insure the door is snug. Do not over--tighten. (See Figure 7.)

Figure 7

Model PH90Operating Procedures

Step 4

Assemble the draw valve spinner assembly. Inspect draw valve o--rings for cuts or nicks. (Replace if cut or nicked.) If draw valve o--rings are in good condition, slide the two o--rings into the grooves of the draw valve and lubricate. (See Figure 8.)

Figure 8

Lubricate the outer diameter of the spinner shaft seal. Fill the cups on each end of the seal with lubricant. Insert the spinner shaft seal into the bottom of the draw valve as far as it will go. The spinner shaft seal should fit into the seal groove located inside the draw valve cavity.

Place an even coat of lubricant on the smaller end of the driven spinner. (See Figure 10.)

Figure 10

Squeezing the split end together, insert the driven spinner through the metal opening of the draw valve until it snaps into place. (See Figure 11.)

Important: Inspect to see that the spinner shaft seal is correctly installed in the groove. A worn, missing, or improperly installed spinner shaft seal will cause product leakage out the top of the draw valve. (See Figure 9.)

Figure 9

Figure 11

Step 5

Lubricate the inside of the freezer door spout, top and bottom. (See Figure 12.)

Figure 12

Model PH90 Operating Procedures

Install the draw valve spinner assembly. Insert the draw valve from the bottom until the slot in the draw valve which accepts the draw handle comes into view. (See Figure 13.)

Install the draw handle. With the stopping tab of the draw handle facing down, slide the fork of the draw handle into the slot of the draw valve. Secure the draw handle with the pivot pin. (See Figure 15.)
