TYPES OF MONITORING:
(A) Below-atmospheric pressure:
P1 (
+
) is not connected
but open against atmosphere
P2 (
–
) connected to inside of duct
(B) Filter:
P1 (
+
) connected upstream of filter
P2 (
–
) connected downstream of filter
(C) Ventilator:
P1 (
+
) connected downstream of ventilator
P2 (
–
) connected upstream of ventilator
Pressure connections at the pressure switch
are marked with
P1 (
+
) for higher pressure and
P2 (
–
) for lower pressure.
