9.4.3 Installing the New Canister
1.
The reverse procedure should be followed to install a new cylinder. The main electrical
disconnect is to be left open until the cylinder is completely installed and reconnected.
2. The blue sensor plug on all units is for the high water sensor pin, which always goes on the
single pin with collar offset from the others. See Figure 9.12 on the facing page.
3. Ensure that cylinder plugs are snug on the pins. Replace any loose fitting plugs as these may
result in hazardous operation.
WARNING! Risk of humidifier canister meltdown, smoke and fire. Can cause fire suppression
system activation, fire and smoke alarm activation, building evacuation, dispatching of fire and
rescue equipment and personnel and water leaks resulting in expensive equipment or building
damage, injury or death. Check steam generating humidifier electrode plugs to ensure that they
are pressed firmly onto pins. Loose connections will cause overheating of cylinder and plugs.
