In the case of an installation with a filter box (option) take account of the thickness of the box for the duct entry:
~ 100 mm.
The duct network must be sized by a qualified air conditioning engineer in compliance with industry rules and best
practices. The engineer must ensure that the network is compatible with the unit's aeraulic characteristics (refer to
§ "FLOW/ AVAILABLE STATIC pRESSURE")
FLOW/ AvAILABLE STATIC PRESSURE
The chart below provides the available static pressure ranges on the blowing side of the indoor units in relation
to nominal flows.

For units from 125 to 185 inclusive, flow / static pressure adjustment is achieved via the electrical connection. For
other units, this adjustment is made with the aid of a variable pulley. When adjusting this pulley, it is important
to ensure that the belt is positioned properly. The pulleys / belt assembly must be aligned perfectly
and the belt tensioned in accordance with best practices.
Refer to the Appendices for the units' electrical diagrams and the aeraulic characteristics in relation to fan speed
settings.
