Connecting the drainage tube

It is recommended to prepare a drainage point with hard PVC ∅ 32 mm tube by a
A.
professional plumber, close to the indoor unit.
B. To enable proper drainage of the condensation water, the passage of the drainage must
be planned in advance with a down slope of at least 1%, without creating any bottleneck
and without upwards bends (see Fig. 12). Take care to integrate a siphon at a minimum
of 50 mm height, in order to prevent penetration of unpleasant smells into the room.
C. The DNC unit includes a drainage pump with level control, which can elevate
condensation water to a level of up to 60 cm from the unit's lower level. The drainage
tube is connected to the upper drainage nozzle (see Fig. 13).
D. Lower drainage nozzle is intended to empty the drainage pool before servicing.
E. To check the system, fill the condense tray with water and verify its free flow through the
drain line.
F. Install insulation of the Arma-flex type of 5-10 mm thickness for the condensation water
line.
