Replacing a caster requires at least two people to
maneuver and tip the machine. Personal injury and/or
machine damage is possible if one person attempts this
procedure alone.
1. Disconnect all pipeline hoses from the wall and the machine,
close all gas cylinders and unplug the power cord.
Remove the vaporizers before tipping the machine. If a
vaporizer is inverted, it must be set to 5% and purged for
30 minutes with a 5 L/min flow. The interlock system
prevents purging more than one vaporizer at a time.
2. Remove the absorber, the vaporizers, gas cylinders, drawers and
all auxiliary equipment.
To prevent damage, do not tip the 9100c machine more
than 10 degrees from vertical.
3. Block the opposite wheels; then, block up the machine until there
is enough room to remove the defective caster. To block up the
machine, tip and slide blocks under the caster base. Raise both
sides evenly until the unit is high enough to remove the caster.
4. The casters are threaded into the base and held with a Loctite
compound. Remove the caster with an appropriately sized open-
end wrench.
5. If required, clean the threads of the new caster with denatured
alcohol.
6. Apply Loctite 242 to the threads of the new caster. Install the
caster securely into place.
7. Make sure the caster turns freely.
8. Carefully lower the machine to the floor.
9. Perform the checkout procedure (Section 3).
