10.4 Servicing
Explosion vents should be inspected regularly to confirm physical and operational
condition. Reference the manufacture’s recommendations and consult with the authorities
with jurisdiction. Replace any damaged or worn parts immediately.
10.5 Safety distance
The material discharged during a vented explosion must be directed outdoors.
Locating equipment with explosion vents outdoors is always recommended.
Measures should be taken to reduce the risk to personnel and equipment from the
effects of fireball temperature and pressure. In the event of a vented explosion, use the
guidance detailed in NFPA 68 to determine the maximum width and height of the flame.

START-UP & OPERATION
11.1 Start-up checklist
Check the compressed air supply to the OptiFlo RC to ensure correct and safe
connection to the compressed air manifold(s). Turn on the compressed air supply to the
manifold(s). Pressure available should be 90-100 psig.
Check that cartridges are properly installed and that the red cam-lock handles on the
port hole doors are all fully engaged (see Section 9.2.7).
Ensure the hopper discharge device(s) (if any) is operating properly. Follow the
manufacturer’s instructions.
Energize the pulse controller and ensure the correct mode and parameters are set
(reference to the controller manual).
Listen for firing of the pilot solenoids and diaphragm valves to determine that they
are all operational. Note that as each solenoid is activated, a “click” can be heard and a
small vibration can be felt on the cover of the solenoid valve enclosure. When the diaphragm
valve is activated, a small jet of air vents from the hole at the solenoid valve base and there
will be a sharp noise as the compressed air is allowed to escape from the compressed air
manifold.
Before introducing any dust to the collector, turn the power off to the controller and
reset the high and low set points to 3” w.g. and 2” w.g., respectively.
Start the fan with the fan damper or duct blast gates partially open. At the same
time, observe the controller’s differential pressure gauge. This gauge indicates the
