Carrier 50CO Series - Optional Components

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 lter when clean (pressure ports upstream and downstream of the lter).
11.1.5 - Standard control elements:
(Factory cables)
- An intake temperature sensor.
- A di󰀨erential pressure sensor: attached to the electrics box, this allows the di󰀨erence in pressure upstream and downstream of
the lter to be measured, so as to determine whether the lter 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 oor, 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).
