Notes:
Models: 3500 W ~ 7100 W
Models 10500 W ~ 17600 W
■ In case of one duct connection
- The air volume in duct is around 300-360 m³/h for model
3500W to 7100W units.
- The air volume in duct is around 400-640 m³/h for model
10500W to 17600W units.
- The max. length of duct is 2m.
- The original air outlet with the same direction of duct
should be sealed In case of two duct connection.
External renewal air, use material suitable for operation at a constant temperature of 60°C. The ducts may be made
from flexible polyester (with a spiral steel core) or corrugated aluminum, clad externally with anti-condensation material
(fibre glass of 12 ÷ 25 mm thick). Once installation is completed, the uninsulated surfaces of the ducts must be covered
with anti-condensation insulation (for example, expanded neoprene of 6 mm thick).
CAUTION
■ The salient of plastic cap in sway motor shall be inserted in
the notch of the water outflow pipe seal board.
■ Do not coil the wiring of the swing motor into the seal
sponge.

■ In case of two duct connection
The air volume in one duct is around 200-260m³/h for
model 3500W to 7100W unit.
The air volume in one duct is around 300-500 m³/h for
model 10500W to 17600W units.
The max. length of duct is 1.5m for one duct.
The original air outlet with the same direction of duct
should be sealed.
