7-4 Maintenance
Replacing Disposables
Disposables are items that are discarded and replaced on a regular basis. The following items are
common disposables and should be replaced as recommended in Table 7-1:
• Purge boot
• Purge Station cup
Tools and Materials Needed
• Replacement purge boot (See Table 7-3)
• Plastic cups
• Needle-nosed pliers
To replace the purge boot:
1. Lift off the purge station lid (Figure 7-2). If the system is running, the lid will be held down by a
partial vacuum.
2. Using needle-nosed pliers, grip the top of the purge boot and pull it out from the top of the lid.
Tearing the boot will not cause a problem, as it is being replaced.
3. Obtain a new boot.
> If using a nozzle, use an olive-colored boot.
> If using a needle, the inside diameter of the boot should be compatible with the outside
diameter of the needle. Refer to Table 7-3 for selection of the appropriate purge boot size.
4. Insert the new boot into the top of the lid, narrow end first.
5. Push the boot downward through the hole in the lid until it starts to emerge from the bottom.
6. Using fingers or a needle-nosed pliers, grip the bottom of the boot and pull gently through the
hole until it is fully seated. Scoring of the bottom end of the boot is acceptable, but the top of the
boot must be undamaged.
