Warranty Information
The manufacturer is not liable for any loss or injury resulting from failure to comply with this manual.
Operational Characteristics
The air conditioner's performance is influenced by the RV's insulation. To improve efficiency:
- Park in shade.
- Enhance insulation, seal openings, use curtains.
- Keep doors/windows closed.
- Avoid heat-generating devices inside.
- Turn on AC in advance.
For high temperatures, use cooling mode and high fan speed.
Note on Condensation: Rapid cooling may cause condensation near the air outlet. This is normal and will dry over time. Keep doors/windows closed to reduce it. Manufacturer is not liable for condensation damage.
