WARNING
• Install new pipes immediately after removing old ones to keep moisture out of the refrigerant circuit.
• Chloride in Some types of refrigerants such as R22 will cause the refrigerating machine oil to deteriorate.
Necessary Tools and Materials
Prepare the following tools and materials necessary for installing and servicing the unit.
Necessary tools for use with R32 (Adaptability of tools that are for use with R22 and R407C)..
