5.1.3 Start-up Procedures
During the first start-up or start-up after a long period of inactivity or following maintenance,
the technician must comply with the instructions below. The start-up must be performed by
qualified personnel only.
The employee that operates the machine must wear hearing and eye protection before
operating the adsorber. Each employee must select proper personal protection equipment
and device(s) (PPE & PPD). Hearing protection such as earmuffs, ear canal caps, or earplugs is
needed in order to prevent permanent hearing damage or loss.
Start-up Sequence
+ Please read and understand the entire manual before operating the carbon tower
+ Verify that all the steps of in the previous chapters relating to installation have been observed
+ Verify that the connection to the compressed air system is correct
+ Remove any packaging and other material that might obstruct the area around the carbon tower
Before bringing pressure to the activated carbon tower, your compressor should be running, your compressed
air system pressurized, and the carbon tower bypassed and not yet pressurized. With the adsorber is
bypassed and in isolation follow these steps.
1.
SLOWLY open the inlet isolation valve allowing compressed air into the carbon tower. It
is critical that the carbon tower be pressurized slowly to prevent damage to the activated carbon
bed. Keep the outlet isolation valve closed at this time.
2.
SLOWLY open the outlet isolation valve. All valves are now in their open positions and
compressed air is flowing through the carbon tower and downstream.
3.
Close the carbon tower bypass valve. The bypass valve must be bubble tight to prevent
any oil vapor from contaminating the dry air outlet from the adsorber.
4.
Check all piping for compressed air leaks.
5.2.
ISOLATION AND SHUT DOWN PROCEDURES
Users operating the machine must wear hearing and eye protection. Each employee must select
proper personal protection device(s) (PPD). Hearing protection such as earmuffs, ear canal caps,
or earplugs are required to prevent permanent hearing damage or loss.
Isolation
1.
Open the bypass valve.
2.
Close the outlet isolation valve.
3.
Close the inlet isolation valve.
Depressurization and Shut Down
1.
Open the bypass valve.
2.
Close the outlet isolation valve.
3.
Close the inlet isolation valve.
4.
Open the manual ball valves on any filters with manual ball valves to allow full
depressurization. Also, leave manual ball valves on filter open during maintenance and service.
IMPORTANT! Always remove all pressure and disconnect all power before servicing the carbon
tower.
