5.2.3 Dismantling

Please observe the following hints before removal of the device to prevent any risk of sparks,
release of flammable gas and explosions (in the hazardous area).
Dismantling is prohibited without switching off all supplies, such as
pressure and electricity (power and communication), beforehand.
It must be guaranteed that the power, communications and gas can not be
accidentally turned back on, so that there is no danger of disassembly.
If you wish to continue using the device at a later time or send it back, you
must return it to the condition in which it was delivered. (transport
protections, dummy plugs, covers etc.)

5.3 Fluidic installation of GasLab Q2

The specified maximum pressure on the gas inlets of Q2 must not be
exceeded in order to prevent damage to the device and dangerous
situations. This must be guaranteed by an external protection, which is not
an integral part of the Q2.
The required tubes and protection devices have to be provided according
to the general guidelines as well as the preconditions in this instruction.

5.3.1 Gas connections

The Q2 has two gas inlets (connection according to chapter 4.2.1). Both are protected by a flame
arrestor.
The Q2 also has two gas outlets (connection according to chapter 4.2.1). One is used to vent
measured gases, the other to bypass the measurement if necessary for speed optimization
purposes.
The gas outlets must vent without any significant gauge pressure (pressure difference against
current ambient pressure) due to back pressure or length of exhaust gas line. Please contact
Elster GmbH for application hints.
The gas inlets and outlets are labelled on the device ( See chapter 10.2.3)
