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 conventional 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”.
