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.
