3.1. About the product

Warning:
Do not use refrigerant other than the type indicated in the manuals
provided with the unit and on the nameplate.
during use, during repair, or at the time of disposal of the unit.
- It may also be in violation of applicable laws.
- MITSUBISHI ELECTRIC CORPORATION cannot be held responsible
for malfunctions or accidents resulting from the use of the wrong type of
refrigerant.
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
conventional 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.
