Compressor Warranty Disclaimer

The refrigeration compressor(s) on this machine are 
warranted for the term stated in the Limited Warranty 
section in this manual. 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 Taylor compressor warranty. It 
is the machine owner’s responsibility to make this fact 
known to any technician he/she employs.

It should also be noted that Taylor does not warrant the 
refrigerant used in its machine. 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 replacement refrigerant either at billable or 
unbillable terms. Taylor will recommend a suitable 
replacement if the original refrigerant is banned, 
obsoleted, or no longer available during the five (5) year 
Taylor warranty of the compressor.

From time to time Taylor may test new refrigerant 
alternates. Should a new refrigerant alternate prove, 
through Taylor’s testing, that it would be accepted as a 
drop-in replacement for this machine, then the disclaimer 
in this Compressor Warranty Disclaimer section will not 
apply to the use of the alternate refrigerant approved by 
Taylor.

To find out the current status of an alternate refrigerant as 
it relates to your compressor warranty, call Taylor or your 
local authorized Taylor distributor. Be prepared to provide 
the model/serial number of the machine in question.
