Indoor unit emits a musty or moldy smell when starting up.

Safety first: Turn off power before cleaning. Wear gloves and eye protection when using coil cleaners.

Steps:

• Clean filters: Wash filters thoroughly and allow to dry.
• Disinfect coil and pan: Use an AC-specific foaming coil cleaner with biocide on the Blaupunkt indoor evaporator and drain pan. Follow product instructions and ensure good ventilation.
• Clear drain: Make sure the drain line is clear so water does not stagnate.
• Use self-clean function: If your Blaupunkt model has a self-clean or dry-coil function, run it regularly to reduce moisture and odor.
