Setting the Pressure Regulator
Before adjusting the flow rate through the pressure regulator, pull out the grey knob
on the right hand side of the regulator (when looking at the plinth from the front):
To increase flow through the pressure regulator, turn the knob slowly in a clockwise
direction (looking at end of knob). The flow rate is measured by a flow meter
downstream of the pressure regulator, and is indicated in L/min on the PCT40
software screen. Flow through the pressure regulator should not be taken above 1.5
L/min as this is the measurement limit of the flow meter. A maximum of 1.4 L/min is
recommended.
To reduce the flow rate through the pressure regulator, turn the knob slowly in an
anticlockwise direction (looking at end of knob):
Once the appropriate flow rate is achieved, lock the regulator setting by pushing the
grey knob back towards the body of the regulator:
