Maintenance
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
1 Gather the following:
• 3/16- inch open end wrench (provided in ship kit)
• 1/4- inch open end wrench
2 Cool down the transfer line and 6 port valve (sample

Disconnecting the transfer line may interrupt GC carrier gas flow.

Be careful! The oven and/or inlet may be hot enough to cause
burns. If either is hot, wear heat-resistant gloves to protect your
hands.
Cool the GC inlet to a safe handling temperature.
