• Stop Odorant Recovery Cycle after about 15
seconds (depending on the installation conditions)
and eventually repeat the procedure if needed.
• Select gas wash time.
• Run gas wash cycle.
• The cycle will be terminated when the Gas Wash
cycle time will expire.
• Put the system in disable mode and turn it off
before maintenance operations.
At this point all valves of the system have to be closed
and you can perform maintenance operations on the
involved parts.
After completing all operations, to restart the system
open the system valves, turn ON the odorizer, reset the
existing alarms and put the system in AUTO (MANUAL
or MINIMUM RATE).
Injection Solenoid Valve Cleaning with
Liquid Odorant (Injector Flush)
NOTICE
During the washing operation with
natural gas the control activates both
injectors at the same time (to increase
the drying process), during injector
flush just the selected injector is
activated. This allows the system to
increase the pressure for cleaning the
dirty injector and reduce potential over
odorization issues.
For injector selection, please refer
to Type Dosaodor-D Software for
Configuration of Type Dosaodor-D
Odorant Injection System
Manual (D103117X012).
