Installation, continued
Connect a drain hose to the correct drain valve at the base of the unit . The unit is manufac-
tures with blanked drain, see marking at the top of the unit (A/B mode) .
IMPORTANT:
Make sure that the cap is moved to the correct drain if you change between A/B mode,
as otherwise condensate cannot be led out of the unit, and this will then lead to an inadvis-
able buildup of water in the unit and the risk of water ingress in the house!
The drain hose must be supplied with a min . 100 mm siphon as shown in Fig . 9 . Guide the
hose to the drain and make sure it does not get exposed to frost .
Fill the siphon with min . 0 .5 L water .

Material damage (e .g . water damage)
Heat recovery of air with a high moisture content leads to condensation in the heat exchang-
er . Condensate must be led into a drain, as it otherwise can damage the floor under the unit .
• Make sure that the drain hose is installed according to the current operating mode .
