Installation
The measuring system ENVIRONcheck 180/181 has to be installed in the 19“ rack as the topmost unit.
The space needed is 6 HU ( 180: 4HU, 181: 2HU). Erecting the 19” rack please mind, that the sample
pipe 182 is to be inserted directly through the ceiling / roof construction into the sample pipe holder 181.
For the exact fitting of the roof penetration a drilling gauge is available at the manufacturer. The outer
diameter of the sample pipe is 45 mm.
Mounting and demounting the measuring device 180 can take place without having to disassemble the
sample pipe and the sample pipe holder. The connection of the electronic unit 180 with the sensors and
the sample pipe happens via a connection module inside the sample pipe holder 181. The ports for the
sample air, the dryer circuit, and the electrical connections are each being lead to a plug module. This is
fix installed in the 181 and mobile via a lift. Taking the device into operation these modules are being
connected. Previous to disassemble the instrument 180 this connection has to be loosened and the device
can be pulled out again, without having to dismount sensors and sample pipe.
