•Removing and Replacing the Enclosure
•Replacing the Gas Lift
•Adjusting the Top Surface
Replacing an AAP
Replace one or more AAPs as follows:
WARNING: Ensure that AC power is disconnected before 
servicing the HSA unit.
1.On the underside of the clamshell and in the enclosure, cut the tie wraps that route the AAP cables out of the way.
2.Remove the top and bottom screws on the right and left sides of the AAP panel (see figure 12 on the next page). Retain the screws. Lift the panel away from the enclosure as far as the connected cables allow and then allow the panel to dangle, supported by its connected cables.
NOTE: The center screws on each side of the AAP panel do
not fasten the AAP panel in place. They secure the AC power outlet.
CAUTION: Ensure that the edges of the AAP panels do not scratch the finished surface of the top panel flange or the furniture in which the HSA 822 is installed when removing the panels.
