DRAIN PIPING
9 Drain PiPinG
9.1 ConDensation DrainaGe sYstem
When the outdoor unit operates in heating mode, there is a build-up of condensation of the ambient humidity which, together with
rain water, requires draining.
Select a location for the unit which permits adequate drainage. If necessary, mount an installation suitable for the drainage of
condensation.

• Drainage must not take place in areas frequented by pedestrians. In low temperatures, the drainage water could freeze and lead to falls.
If it is necessary to install the outdoor unit in an area frequented by pedestrians, an additional drainage tray should be fitted.
• Do not fit drainage pipes or collection trays in cold climates, as they could freeze and break.
If a condensation drainage kit is required for the outdoor unit, use the optional drainage kit DBS-TP10A.
