FRESH AIR SUPPLY (see page 56 for kit details)
CC 875 units are fitted with an inlet to allow the installer to provide a fresh air supply
The 100mm dia. spigot is available as kit 55200305.
The installer must provide ductwork, a screened source of fresh air and an auxiliary
fan.
The auxiliary fan must be sized to overcome the resistance of the filter, the ductwork
and the cassette itself. (To prevent excessive noise, the maximum fresh air volume
should be less than 5% of the nominal air volume for any given unit and fan speed).
The auxiliary fan should be connected to a separate electrical circuit, appropriately
fused and isolated.
