11 - TECHNICAL SPECIFICATIONS
Filter fouling is measured by a pressure sensor located in the electrics box.
It is set to 1.5 times the value for the filter when clean (pressure ports upstream and downstream of the filter).
11.1.5 - Standard control elements:
(Factory cables)
- An intake temperature sensor.
- A differential pressure sensor: attached to the electrics box, this allows the difference in pressure upstream and downstream of
the filter to be measured, so as to determine whether the filter is fouled.
- A water leak sensor: this is found at the end of a wound cable located at the bottom of the unit so that it is long enough to extend
downwards into a raised floor, if required, and to be positioned in the area to be monitored. It can be added on request.
It can be added on request.

11.2 - Optional Components

11.2.1 - Heating coil

Moderately tighten the "coil supply" connections to avoid damaging the manifolds.
The coil is adjusted by a two-way or four-way valve equipped with a 0-10V servomotor (mounted and connected).
