Water Connections
(Water Cooled Units, 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 underside of the
base. These connections are 3/8" FTP.
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 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 open trap drain.
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.
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.
Model 430
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:
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.
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
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 owners'
responsibility to make this fact known to any
technicians they employ.
It should 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
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, call the local Taylor Distributor or the
Taylor Factory. Be
model/serial number of the unit in question.
