Assembly and Installation
Subject to change without notice
Connect emergency air valves (3) between flexible DN 25 cooling air hoses (6) and the
cooling air inlet of the S/R units using hose clamps (5). The different connection diameters
determine the assembly direction (in flow direction) of emergency air valves (3).
Connect emergency air lines (4) (switched compressed air) via quick-connectors to Y
branch (2c) on junction box solenoid valve (2) and screw fittings (3b) on emergency air
valves (3). Connect the compressed air supply (instrument air free from oil, grease and
water) via connection plug (2b).
Arrange the MCU (7), S/R units, supply lines and junction box solenoid valve so that both
flexible DN25 cooling air hoses(6) from the MCU blower unit and emergency air lines (4)
from junction box solenoid valve (2) to both S/R units have the same length (same
pressure loss, same amount of cooling air on FLSE100 A and B).
