Disconnect Switch
If the machine has no plug, a separate disconnect switch
must be installed, or another alternate means to
disconnect power must be implemented.
Water Connections
Water-Cooled Machines, Only
An adequate cold water supply must be provided with a
hand shut-off 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 Specifications.”)
Flexible lines are recommended, if local codes permit. In
Europe, hose sets for connection of appliances to the
water mains must comply to the International 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.
Refrigeration
CAUTION! In consideration of our environ-
ment, Taylor uses only earth-friendly HFC refrigerants.
The HFC refrigerant used in this machine is R404A. This
refrigerant is generally considered nontoxic and nonflam
-
mable, with an ozone-depleting potential (ODP) of zero
(0). However, any gas under pressure is potentially haz
-
ardous 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 R404A refrigerant that
conforms to the AHRI standard 700 specification. The
use of any other refrigerant may expose users and oper
-
ators 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 immedi
-
ately.
NOTICE! Taylor reminds technicians to be
aware of government laws regarding refrigerant recovery,
recycling, and reclaiming systems. If you have any ques
-
tions regarding these laws, please contact the factory
service department.
