2. About the product
•
This unit uses R410A-type refrigerant.
•
Piping for systems using R410A may be different from that for systems using
conventional refrigerant because the design pressure in systems using R410A
is higher. Refer to the Data Book for more information.
•
Some of the tools and equipment used for installation with systems that use
other types of refrigerant cannot be used with the systems using R410A. Refer
to the Data Book for more information.
•
Do not use the existing piping, as it contains chlorine, which is found in con-
ventional refrigerating machine oil and refrigerant. This chlorine will deteriorate
the refrigerant machine oil in the new equipment. The existing piping must not
be used as the design pressure in systems using R410A is higher than that in
the systems using other types of refrigerant and the existing pipes may burst.
