______________________________

We at Taylor are committed to manufacturing safe
operating and serviceable equipment. The many
built-in safety features that are part of all Taylor®
equipment are aimed at protecting operators and
trained service technicians alike.

This manual is intended exclusively for

Taylor authorized service personnel.

DO NOT attempt to run the equipment

unless you have been properly trained to do so.

CAUTION: THIS EQUIPMENT MUST BE

PROPERLY GROUNDED! Do not operate this unit

unless it is properly grounded and all service panels
and access doors are restrained with screws. Failure
to do so can result in severe personal injury from
electrical shock!

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.

If the supply cord is damaged, it must be
replaced by an authorized Taylor service
technician in order to avoid a hazard.

Failure to follow these instructions may result in
electrocution or damage to the unit.

S DO NOT attempt any repairs unless the

main power supply to the unit has been
disconnected.

S DO NOT operate the unit with larger fuses

than specified on the data label.

S Stationary appliances which are not

equipped with a power cord and a plug or
other 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.

DO NOT partially remove the ice hopper
cover. Complete removal of the hopper cover is
required when accessing the ice bin. Failure to
follow this instruction may result in personal injury.

DO NOT remove any internal operating
parts unless all control switches are in the OFF
position. Failure to follow these instructions may
result in severe personal injury from hazardous
moving parts.

Installer Safety

Electrical Connections

In all areas of the world, equipment should
be installed in accordance with existing local codes.
Please contact your local authorities if you have any
questions.

Care should be taken to ensure that all basic safety
practices are followed during the installation and
servicing activities related to the installation and
service of Taylor® equipment.

S Only authorized Taylor service personnel

should perform installation, maintenance,
and repairs on Taylor equipment.

S Authorized service personnel should consult

OSHA Standard 29CFRI910.147 or the
applicable code of the local area for the
industry standards on lockout/tagout
procedures before beginning any installation
or repairs.

S Authorized service personnel must ensure

that the proper personal protective
equipment (PPE) is available and worn
when required during installation and
service.

S Authorized service personnel must remove

all metal jewelry, rings, and watches before
working on electrical equipment.

The main power supply(s) to the units must
be disconnected prior to performing any installation,
maintenance, or repairs. Failure to follow this
instruction may result in personal injury or death
from electrical shock or hazardous moving parts as
well as poor performance or damage to the unit.

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.

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

Refer to the Electrical Specifications on page 4 for
proper field wire connection.

It is recommended that the unit be plugged into an
electrical surge protector for added protection
against power surges, which could damage an
electrical/electronics component. An electrical surge
event may cause the unit to shut down. Such an
event would require service by a qualified service
technician if the unit was not adequately protected.
A good surge protector, as would normally be used
on a home computer, should be adequate and is
available at most computer retail outlets or electrical
supply stores.

This unit has many sharp edges that can

cause severe injuries.

Water Connection

New hose sets supplied with the appliance are to be
used and old hose sets should not be re-used.

Model SB25

FOLLOW YOUR LOCAL ELECTRICAL CODES!

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

Customer Numbers

Two customer numbers can be stored in the
shaver/blender controller PCA memory, containing
separate recipe and calibration settings. These are
selected by a DIP switch setting inside the system,
located on the top edge of the dispense PCA
assembly. Position 5 is used to select the customer
number. (Position 6 is used to enable or disable the
cane pump option on the SB25, if it is functioning.)

S Customer 1 - Switch Position 5 OFF
S Customer 2 - Switch Position 5 ON

When you power up the system, the customer
selected number is displayed briefly (one second)
before showing the default menu settings.

S If recipe key 1 is on briefly at power up, the

DIP switch is set to customer 1.

S If recipe key 2 is on briefly at power up, the

DIP switch is set to customer 2.

instruction may result in personal injury from blade
contact.

Step 3

Install the hopper cover and run the manual blend
cycle until all remaining ice is dispensed.

Step 4

Wait 30 seconds after disconnecting power
before removing the drive board cover.

Electrostatic Discharge Protection

Electrostatic Discharge (ESD) is the rapid discharge
of static electricity from one conductor to another of
a different potential.

An electrostatic discharge can damage integrated
circuits found in computer and communications
equipment. Follow instructions where noted.
