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