11.7 Mostly gas-tight version (option for M 53 and M 115)
With this option the high performance temperature chamber is additionally sealed, so the loss when in-
troducing gases is decreased. The unit is not completely gas-tight, so it is impossible to establish over-
pressure. The sealing diminishes the release of vapors via the housing that may be set free from the
charging material when heated. Carrying-off via the regular evacuation duct, e.g. into a waste air installa-
tion, is likely to further reduce emissions.
The unit is not completely gas-tight. Gases from inside the high performance temperature
chamber can escape into the surrounding atmosphere.
Respect the maximum working place concentration of the released substance. Respect the
relevant regulations.
Any harmful gas that might escape has to be led out via good room ventilation or a suitable
exhaust system. Place the unit, if necessary, below a gas vent.
The air flap does not close the exhaust duct completely. The delivered plug serves to avoid emerging of
vapors or loss of introduced inert gas, if any, via the exhaust duct. Due to special demands of heat resis-
tance, use the delivered plug only.
CAUTION
Use of inappropriate plug.
Danger of inflammation.
¾ To close the exhaust duct use the delivered plug only.
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.
11.8 Inert gas connection (option for M 53 and M 115)
With this option, the high performance temperature chamber is equipped with two ports for inert gas (on
top in the middle, and down at the right, both on the rear of the unit). Each of these ports can be used as
inlet or outlet, depending on the nature of the inert gas (heavy gas: upper port as inlet, lighter gas: lower
port as inlet).
Connect a flexible gas tube to the gas tube connection adapter (diameter 10mm) used for gas inlet, and
secure it with hose clamps (not enclosed).
The unit is not gas-tight. Gases from inside the high performance temperature chamber can escape into
the surrounding atmosphere.
Any gas that might escape has to be led out via good room ventilation or a suitable exhaust system
WARNING
High concentration of inert gas.
Danger of poisoning.
∅
Do NOT set up units in non-ventilated recesses
¾ Ensure technical ventilation measures
¾ Respect the relevant regulations for handling these gases.
The “Mostly gas-tight version” (option for M 53 and M 115, chap. 11.7) reduces the loss of
gas.
