ROUTINE MAINTENANCE—REPLACEABLE COMPONENTS
The Integritest Exacta Instrument requires very little maintenance. There are a small number of
user replaceable components that may need replacement.
Replaceable Parts
• Cooling Fan filter (low back-pressure HEPA-like filter)

inkjet cartridge (see Replacing the Ink Cartridge, page 146)
Fan Filter Replacement
The fan filter (catalogue number XITXSP110) is a HEPA
®
-like filter that removes particles from
the Integritest Exacta instrument’s cooling fan exhaust. It is recommended that the filter be
replaced every 6 months. The actual replacement frequency will vary depending on the
cleanliness of the environment where the instrument is used.
The filter is not required to operate the Integritest Exacta instrument. If filtration of the cooling
fan exhaust is not necessary, the user can choose to remove the fan filter and operate the
instrument without it.
