3.5.2 Connecting the condensate pipe to the indoor unit
Depending on the type of installation, the condensate pipe must either
be connected to the integrated condensate pump or the condensation
catch pan.
▶ Use PVC pipes with 32 mm inside diameter and 5-7 mm wall
thickness.
▶ Insulate drain pipe to prevent condensate formation.
▶ Connect drain pipe to indoor unit and secure connection with a hose
clip.
▶ Install drain pipe on slope ( Fig. 28). With a condensate pump
installed, the outlet of the drain pipe may be higher than the indoor
unit if the dimensions and wiring diagram are observed.
NOTICE
Danger due to water damage!
If the pipes are routed incorrectly, water may be discharged, or may flow
back into the indoor unit and cause the water level switch to malfunction.
▶ With a ceiling-mounted installation: to prevent the pipes from
sagging, install a support point every 1–1.5 m.
▶ Route a drain pipe to the sewer via a siphon.
Dismounting the drain pump
The indoor unit is delivered with the drain pump from factory for ceiling-
mounted installation. If the indoor unit will be used as floor-standing,
drain pump must be removed.
The drain pump should be removed first during pipe connection.
Observe the following instructions on how to proceed:
