Ductwork
IMPORTANT:
Duct calculation and design must be effected by a qualified
technician.
The duct dimensions should be determined in accordance with the
air flow and with the available static pressure of the unit.
It is advisable to follow the below suggestions:
• Whatever type of duct is used, it should not be made of materials
which are flammable, or which give off toxic gases in the event of
a fire.

The inside surfaces should be smooth, and not contaminate the
air which passes through.
• At the points where the duct joins with the unit, it is advisable to
use a flexible connection which absorbs vibration and prevents the
transmission of noise inside the ductwork.
• Bends should be avoided as much as possible near the unit outlet.
If unavoidable, they should be as slight as possible, and internal
deflectors should be used when the duct is of large dimensions.
