Filter fouling is measured by a pressure sensor located in the electrics box.
It is set to 1.5 times the pressure drop value for the filter when clean (pressure tapping upstream and downstream of the filter).
7.2 - Cooling coil:
Note
: make sure that the chilled water supply pipes are insulated.
Moderately tighten the coil supply connections to avoid damaging the manifolds.
