During cooling, the fan coil element temperature can drop below the air's dew point, leading to condensation.

Condensate tray

It collects the water that forms on the element.

Drainage

The condensate piping must have the correct slope or use a condensate pump where required.

Pipe insulation

Cold water pipes must have continuous insulation with a vapor barrier to prevent moisture from appearing on the outside.

Common problems

Clogged drainage, poor slope, or insufficient insulation can cause dripping and damage to the space.
