CAUTION
Use of inappropriate plug.
Danger of inflammation.

Use only the supplied plug to close the exhaust duct.
For drying purpose, please remove the plug in order to permit dissipation of the generated vapor, which
would lead to condensation in the inner chamber.
11.9 Inert gas connection with mostly gas-tight version (option for M 53 and M
115)
With this option the chamber is additionally sealed, so the loss when introducing inert gases is de-
creased. For details on the mostly gas-tight version please refer to chap. 11.8).
The chamber is equipped with two ports for inert gas (nitrogen or noble gases).
The ports are located on the top panel in the middle and on the right side at the bottom right . Each
of these ports can be used as inlet or outlet, depending on the nature of the inert gas:
•
lighter gas (nitrogen, helium): lower port as inlet
•
heavy gas (e.g. argon): upper port as inlet
Connection
Observe the legal requirements and relevant standards and regulations for the safe handling of gas cyl-
inders and inert gases.
General information for safe handling of gas cylinders:
•
Store and use gas cylinders only in well ventilated areas.
•
Open the gas cylinder valve slowly to avoid pressure surges
•
Secure gas cylinders during storage and use against falling (chaining).
•
Transport gas cylinders with a cylinder cart, do not carry, roll, or throw them
•
Always close the valve even with apparently empty cylinders; screw on the cap when not in
use. Return gas cylinders with the valve closed
•
Do not open gas cylinders by force. Mark them when damaged
•
Observe relevant regulations for dealing with gas cylinders.
Connect a flexible gas tube to the gas hose connection adapter (diameter 10mm), which is used for gas
inlet, and secure it with hose clamps (hose and hose clamps are not enclosed). There is a constant gas
flow after establishing the connection.
After connecting the gas cylinder, check all gas connections for leaks (e.g. with leak spray or
diluted soap solution).
Use a pressure reducer and make sure to avoid any excessive outlet pressure when connecting the gas
hose to the chamber.
The chamber is not completely gas-tight. Inert gases from inside the chamber can escape into
the surrounding atmosphere.
