SAFETY NOTES

•    Always use extreme care when performing 

    maintenance on an odorization system. 

    Check to ensure the removal of liquid 

    odorant and pressure from the portion of the 

    system on which work will be performed prior 

    to removing components or fittings.

•    Inspect all tube fittings and valve packings 

    semi-annually to ensure that liquid odorant 

    remains within the system.

Step-by-Step Resolution

Using a step-by-step method to resolve issues 

on the NJEX LVO System will reduce maintenance 

time and assist in returning the odorization 

system to service quicker.

The following represent the recommended 

chronology to resolve issues:

1.   Re-establish the correct pressures 

    a.   Bulk Storage Tank, 10 psi (0.7 Bar)

    b.   Actuation Supply, 30-60 psi (2.1 - 4.1 

        Bar), refer to 

Table 1, Page 5

.

2.   Verify that the odorant storage tank has 

    sufficient odorant in it to supply the NJEX  

      LVO 610G / 610F with odorant.
