5 Maintenance
5-10
8 Clean the argon gas exhaust outlet with a cotton swab or gauze and then a vacuum
cleaner.
9 Blow off the evaporant in the vinyl hose outside of the room and clean the inside of the
hose. If the hose has hardened, replace it with a new one. After cleaning, attach the
vinyl hose. Apply a small amount of grease on the outer surface of the exhaust pipe
and insert the hose.
Note
● Improper or loose fitting of the exhaust outlet pipe and vinyl hose
may result in analytical value fluctuations. Cut the tip of the hose
and use an appropriate part for connection or replace the hose with
a new one.
● If the exhaust hose is bent, gas cannot flow properly, leading to
analytical value fluctuations. Make sure that the exhaust hose is not
bent.
