Roof Mounting (Accessory); Connection Of The Air Duct - Salda AMBERAIR COMPACT S-CX H Operation, Installation & Maintenance Instructions

4.8. ROOF MOUNTING (ACCESSORY)

4.9. CONNECTION OF THE AIR DUCT

• The connected air ducts must not be bent and must be fixed separately.
• Make sure that the fans may not be accessed through air duct heads. Otherwise, a protective grid should be installed. You may choose the grid
from the range of products provided on our website https://select.salda.lt.
• Do not reduce the diameter of the piping near the air inlet or exhaust ducts. If you want to reduce the airflow speed in the system, also to reduce
pressure and noise level, you can increase the diameter.
• In order to reduce the level of noise in the air supply system, install silencers (see the chapter on air supply system installation).
• In order to reduce air loss in the system, the air ducts and profile components should be of class C or higher. The catalogue of the above-men-
tioned items can be found on our website https://select.salda.lt.
• External air and exhaust system piping should be isolated in order to prevent heat loss and condensation.
• We recommend to maintain a distance of up to 8 meters between air intake and air exhaust ducts. The air intake point should be installed away
from potential air pollution sources.
• When installing air ducts next to the ventilation equipment, brackets must be used. They suppress vibration and assure secure installation of the
various system parts. The necessary brackets can be found in our catalogue or on our website https://select.salda.lt.
• Air ducts are often mistakenly connected in an inappropriate location. The ventilation units bear the labels indicating the correct air duct connec-
tion layout. Before starting up the system, carefully check if all related works have been performed properly.
The ducts should be insulated according to local regulations and standards.

For flange diameters see section "DIMENSIONS".
We recommend installing shut-off valves in the air intake and exhaust ducts. When operating the air handling unit with a water
coil, a spring-loaded shut-off valve must be installed in the air intake duct.
The supply air temperature sensor is installed in the supply air duct after the coil, so it is necessary to leave space for the
sensor in the straight duct.
