Removing and Replacing the Enclosure
The procedures for replacing the gas lift and adjusting the levelling of the top surface require removing the HSA 822 from the table. Remove and replace the surface mount enclosure for maintenance 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.Disconnect the IEC power cord and
3.On both AAP panels, remove the top and bottom screws on the right and left sides of the AAP panel (see figure 12 on page 18). Retain the screws. Lift the panels away from the enclosure as far as the connected cables allow and then allow the panels to dangle, supported by their 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.

or bent. Exercise caution when handling and mounting the enclosure. Mishandling can damage the appearance of the enclosure.
•The surfaces of the HSA enclosure have screws and other protruding hardware that could damage fine furniture. Do not rest the enclosure on unprotected furniture.
8.On the underside of the table, remove the two bolts that secure the clamshell to the surface mount enclosure (see figure 15 on the next page). Lift the enclosure out of the table.
9.Remove and retain the four corners screws on each side of the enclosure shroud “cube”. Remove the two halves of the shroud.
NOTE: You do not need to remove the center screws on each
side. They do not secure the shroud in any way; rather, they provide structural support to the enclosure.
10.Perform the desired maintenance or modification procedure.
11.If the surface is not level or the top panel is not level with the flange, adjust the top surface. See “Adjusting the Top Surface” in this chapter.
12.Connect the appropriate cables to the rear of the AAPs installed on the AAP panels. Route the cables through the hole in the underside of the surface mount enclosure and connect them to the rear of the AAPs. Refer to the cabling information in the documentation for the AAP.

WARNING: The flanged edges of the top of the surface
enclosure are sharp when the HSA is removed
from the table. Exercise caution when handling to prevent personal injury.
15.Secure the two shroud halves to the enclosure frame with the eight screws per shroud half (four per side) removed in step 9. Orient the shroud halves such that the vertical column of center holes align with the column of screw inserts on the vertical slides.
16.Carefully lower the HSA enclosure into the table opening. From the underside, bolt the clamshell to the enclosure with the two bolts removed in step 8.
