Beater Rotation
NOTICE! Beater rotation must be clockwise as
viewed looking into the freezing cylinder.
WARNING! Disconnect all power to the
machine . Failure to follow this instruction may result in
serious electrical shock.
To correct rotation on a three-phase machine,
interchange any two incoming power supply lines at the
machine main terminal block only.
To correct rotation on a single-phase machine, change
the leads inside the beater motor by following the
diagram printed on the motor label.
It is recommended that the beater rotation adjustment be
performed by a Taylor service technician.
Water Connections
(Water-Cooled Machines Only)
An adequate cold water supply must be provided with a
hand shutoff valve. The water inlet and drain connections
are located on the right side or the underside of the base.
These connections are either 3/8 in. or 1/2 in. FTP,
depending on the model of the machine. (Refer to Model
C161 Specifications on page 1-6.)
Flexible lines are recommended if local codes permit
their use. In Europe, hose sets for the connection of
appliances to water mains must comply to the IEC 61770
standard.
The water expansion valve setting should be set at

255 psig (1758 kPa).
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 shutoff 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
open trap drain.
IMPORTANT! A backflow prevention device is
required on the incoming water connection side. Please
see the applicable national, state, and local codes for
determining the proper configuration. Water pressure to
the unit must not exceed 150 psi (1034 kPa).
Refrigerant
CAUTION! This machine contains fluorinated
greenhouse gases (F-Gas) to provide refrigeration using
a hermetically sealed circuit or within foam insulation.
This machine's type of gas, quantity, Global Warming
Potential (GWP) and CO
2
tonnes equivalent information
is recorded on the unit's data-label. The refrigerant used
is generally considered non-toxic and non-flammable.
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.
CAUTION! Use only approved refrigerant
listed on the machine's data-label or authorized through a
manufacturer's technical bulletin. The use of any other
refrigerant may expose users and operators to
unexpected safety hazards.
WARNING! Refrigerant liquid sprayed onto the
skin may cause serious damage to tissue. Keep eyes
and skin protected. If refrigerant burns should occur,
flush the area immediately with cold water. If burns are
severe, apply ice packs and contact a physician
immediately.
NOTICE! Taylor reminds technicians to be
aware of government laws regarding refrigerant recovery,
recycling, and reclaiming systems. If you have any
questions regarding these laws, please contact the
factory service department.
