INSTALLATION
The constant airflow or pressure kit features a ring to be positioned on air ducts; the pressurised air intakes must always be oriented
downwards to prevent the introduction of dust or foreign bodies into the system, as they could cause it to malfunction.
CONSTANT PRESSURE
The kit should be fitted on the exhaust air side (A) of the supply fan
unit to detect the pressure downstream.

CONSTANT AIRFLOW
The kit should be fitted on the exhaust air side (A) upstream of the fan
unit to detect the differential pressure without risking the falsification
of measurements by turbulence.
If two kits are required, the other should be fitted on the fresh air side
(B).
