WARNING
CAUTION
CAUTION
When performing piping work do not
mix air except for specifled refrigerant
(R410A) in refrigeration cycle. It
causes capacity down, and risk of
explosion and injury due to high
tension inside the refrigerant cycle.
• Refrigerant gas leakage may cause
fire.
• Do not add or replace refrigerant
