Replacing the Gas Lift

The gas lift that raises the HSA surface is rated for 100,000 opening and closing cycles. Contact the Extron S3 Sales & Technical Support Hotline at the nearest phone number listed on the rear cover of this manual to obtain a replacement gas lift. Replace the gas lift as follows:

		Ensure that AC power is disconnected before
		servicing the HSA unit.
		When the HSA 200 is upside-down, the latch may
	CAUTION	When the HSA 200 is upside-down, the latch may
		be ineffective. If the latch releases in this position,
		the enclosure will tip and could damage the flanged
		edges. Keep a free hand on the enclosure to keep it
		from tipping.
1.	Remove the surface mount enclosure from the table. See
	“Removing and Replacing the Enclosure”, steps 1 through
	4. Place the enclosure upside-down on a horizontal
	surface. To protect the finish, place the enclosure on a soft
	cloth.
2.	Loosen the three Phillips head screws that secure the gas
	lift mounting plate in place (figure 3-5).

Unscrew mounting plate from gas lift.

Loosen (3) screws.

Figure 3-5 shows an HSA 200 model. Removing the gas lift mounting plate from an HSA 222 is an identical procedure.

3.	Slide the gas lift mounting plate toward the center of the
	enclosure, releasing the mounting plate (figure 3-5).
4.	Turn the gas lift mounting plate counterclockwise until the
	plate comes free from the shaft of the gas lift (figure 3-5).
5.	Turn the surface mount enclosure onto its back side and
	open the top panel.

With the gas lift removed, the top panel must be manually lifted.

6.(HSA 200 models only) Remove the four 1/16" hex head screws on the right and left sides of the front panel (figure 3-6). Retain the screws. Lift the panel away from the enclosure.
