Replacing the Gas Lift

The gas lift that raises the HSA surface is rated for 100,000 opening and closing cycles. 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

 

 

 

 

 

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 Philips 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 — Removing the gas lift mounting plate

 

 

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.

Figure 3-6 shows an HSA 200 model. Removing the front panel from an HSA 222 is an identical procedure.

Remove 2 hex head screws on each side.
