About The Product; Combination Of Heat Source Units - Mitsubishi Electric City Multi PQHY-P-YHM-A series Installationshandbuch

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
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.
Caution:
• Do not vent R410A into the atmosphere.
• R410A is a Fluorinated Greenhouse gas, covered by the Kyoto Protocol
with a Global Warming Potential (GWP) = 1975.
