UTION:
Odorant has a very strong odor, which if allowed to
escape to the atmosphere, may cause problems in the
local community. Take necessary precautions when
filling an odorant storage tank to assure that the local
community is not disrupted during the filling process.
Verify that the entire system has no pressure in it before
beginning. Additionally all personnel should wear
protective clothing, and use equipment as recommended
by the chemical manufacturer during this time. If you are
uncertain about any aspect of the odorant itself, you
should contact the manufacturer of your chemical prior
to proceeding.
1. Place the N-300 controller in the Standby Mode
by pressing the Standby key.
