Klarstein portable air conditioner exhaust hose becomes very hot and room does not cool well.

Safety: Ensure the unit is unplugged when adjusting hose connections.

Steps:

• Shorten hose: Use the shortest possible length of exhaust hose and avoid sharp bends or kinks.
• Seal window kit: Check the Klarstein window sealing kit for gaps. Use foam strips or tape to seal around the panel and exhaust adapter.
• Check outlet: Ensure the outside exhaust outlet is not blocked by covers, plants, or debris.
• Insulate hose (optional): In very hot rooms, wrapping the exhaust hose with insulation can reduce heat radiated back into the room.
