Semiconductor and other manufacturing industries. The Midas gas detector (MIDAS-T-001) is comprised of 4 main parts: the main chassis, the ® mounting bracket assembly, the sensor cartridge and the unit cover. Diagram 1 details the Midas general arrangement.
2. Mounting Details The Midas gas detector has an integral mounting bracket assembly that is easily mounted ® to a suitable vertical surface such as a wall, tool housing, mounting plate on a pole etc. Drill Template Drill 2 x M4 holes 58.50mm...
Unscrew the thumbscrew located on the front panel. Remove the cover by pulling it forwards off the main chassis. On new Midas ® units, be sure to remove the internal packing card securing the pump. Failure to remove this packing will result in damage to the Midas unit.
