Can the induction terminal units be connected in series?
Yes. However the limiting factor is the velocity of the primary air, a function of the air quantity, entering the first plenum. Too high a velocity can generate unwanted noise. A practical limit is 9m/s. If the design layout demands units be connected in series, contact Dadanco to discuss a larger spigot connection, and possibly a larger plenum.
 
Should the perimeter units blow at or away from the windows?
Experience has clearly shown that the correct method is to blow away from the window for Australian installations. If the application is for, say, North America and its colder regions, there is a practical requirement to blow a proportion of the supply air at the window in winter and the majority into the room, away from the window. This amount can still be directed at the window in summer or, if the outlet design allows, the air pattern can be adjusted to blow away from the window, which is the preferred arrangement.
 
What is the clearance required for air entry to a CM coil, and lint screen access?
At least 300mm, set by the lint screen access requirement. From a need to allow adequate air entry to the coil, around 150mm would be sufficient.
 
Are induction terminal units noisy?
No. The older installations used circular nozzles in a variety of sizes and configurations. The multi-lobed STARLINE nozzle developed by Dadanco is much quieter, partly as a result of the lower operating pressure it operates at. Noise data from tests is available on application to Dadanco, or reference to the Noise section of the Dadanco System Handbook.
