4.2 Maintenance of Indoor Unit
Use the specified non-flammable refrigerant (R410A) to the outdoor unit in the refrigerant cycle.
Do not charge the unit with materials other than R410A, such as hydrocarbon refrigerants
(propane, etc.), oxygen, flammable gases (acetylene, etc.) or poisonous gases when installing,
maintaining and moving the unit. Contamination of these are extremely dangerous and may
cause an explosion, fire, and injury.
