3 Installation of R32 Air to Water Heat Pump
CAUTION
R32 refrigerant Air to Water Heat Pump installation
• ThisAirtoWaterHeatPumpadoptstheHFCrefrigerant(R32)whichdoesnotdestroyozonelayer.
Therefore, during installation work, make sure that water, dust, former refrigerant, or refrigerant oil does not enter
the R32 refrigerant Air to Water Heat Pump cycle. To prevent mixing of refrigerant or refrigerant oil, the sizes of
connecting sections of charge port on the main unit and installation tools are different from those of the conven-
tional refrigerant units.
Accordingly, special tools are required for the R32 or R410A refrigerant units. For connecting pipes, use new and clean
piping materials with high pressure fittings made for the R32 or R410A only, so that water and/or dust does not enter.
• Whenusingexistingpiping,referto“15APPENDIX-[1]Existingpiping”.
■ Required Tools/Equipment and Precautions for Use
Prepare the tools and equipment listed in the following table before starting the installation work.
Newly prepared tools and equipment must be used exclusively.
