De'Longhi Portable Air Conditioner Codes

• HL HL (or Ft) on a De'Longhi portable air conditioner means the unit is full of water and has to be drained.
• Lt Lt on a De'Longhi Pinguino means "Low Temperature" — the frost protection has paused the unit, and it restarts by itself after defrosting.
• PF PF on a De'Longhi Pinguino means "Probe Failure": a probe is damaged, and De'Longhi says to contact customer service.
