Replacing a Variable Speed Blower
WARNING: The blower blades rotate at a high speed and do not stop
immediately
when power is removed. Allow time for the blades to stop
rotating. Avoid touching the rotating blades when removing the blower.
Caution: Removing a power supply significantly changes the airflow within
the MSA1000. After removal of a power supply, the remaining supply starts a
timer that will shut the system down in five minutes, if the removed power
supply is not replaced.
Note: The power supply design ensures that removing a blower does not change the
airflow within the enclosure. However, do not remove a blower until the replacement
blower is available
.
To remove the blower from the power supply:
1. Push in on the two port-colored blower tabs 1 while pulling on the blower
element 2. See Figure 35 for an illustration.
