5.11 Caster Replacement

Refer to "Figure 5-53 Elevating Base".

The casters may be replaced with the unit upright or carefully placed on its back. You may wish to lock the

canopy in its shipping position.

1. Lock all the other casters.

2. Lift the caster off the floor and use blocks to support the leg near the caster you are replacing.

3. On newer casters with mounting plates, remove screw from boss underneath the leg casting.

On older casters with a set screw on the side of the leg casting, remove the screw on the side of the leg

that holds the caster in its mounting hole. Remove the caster.

NOTE: The new style caster with a mounting plate has a different shaft diameter than the older caster and

will not fit on the older set screw style leg casting.

4. On newer casters, secure the caster to the leg by tightening the screw through the caster plate into the

boss in the bottom of the leg.

5. On older casters, line up the hole in the caster stem with the set screw hole in the leg and insert the caster.

Apply Loctite #242 to the screw. As you tighten the screw the caster should be drawn into the leg.

NOTE: If you are replacing a caster hub cover, you must use an 1/8" drill to remove the old cover stem before

snapping the new hub cover in place.

Refer to "Figure 5-54 Chassis Bottom Cover" and "Figure 5-56 Humidifier Parts".

A design change was made to the humidifier assembly to make it easier to remove the screws during

disassembly. Units shipped since about March 2002 have this revised design. The earlier design can be

identified by the button head cap screws used in the assembly. The later design uses Phillips head screws to

make disassembly easier.

When working on the earlier design if you have difficulty with disassembly you may wish to replace the

entire humidifier assembly with the later design 6600-0245-850 . When disassembling the older design, we

recommend that you replace the old screws with the new screws listed below. You may also require the other

parts listed below if they are damaged during disassembly. (Refer to section 5.12.1.)

The reservoir switch button was also redesigned to prevent it jamming in the closed position. You should also

replace this button when working on an old style humidifier.
