Annual Maintenance
Change Auto-Drain Air Filter
Introduction
The filter element in the air regulator auto-drain must be changed at least once a year. This coalescing filter scrubs any
particulate matter out of the printer air supply as the auto-drain removes the moisture.
Purpose
If the filter element gets too dirty or becomes clogged with particles taken out of the air supply, the ability of the auto-drain
to extract moisture from that air is compromised.
When to do
Inspect the filter element every few months by following steps 1 and 2 below. If the filter looks dirty, replace it. Otherwise,
replace yearly.
Required tool
Replacement Filter - no tools required
Caution:
The filter container is under pressure (80 psi). Turn off the house air supply and depressurize all air lines connected
to the filter. There is a risk of personal injury if released under pressure.
How to Replace the Filter
1.
Shut off the house air supply and open the ink enclosure door. Depressurize the machine by disconnecting the air hose from
the tube connector on the left side of the regulator assembly in the ink enclosure.
2.
Unscrew the threaded collar and carefully remove the bowl. Clean (using mild soap and water only) and thoroughly dry all
internal parts and the bowl before reassembling.
3.
Examine the filter for the following:
• Dirt
• Liquid or oil in the bowl - should not be above the lower baffle holding the filter element.
• Differential pressure indicator - should not extend more than half way into the clear dome located above the retaining ring
on top of the filter body.
If one or more of the above conditions exists, continue to step 4 and replace the coalescing filter. Otherwise, replace once
per year.
4.
Unscrew the lower baffle and remove the old filter element. Insert the new filter element and replace the lower baffle; tighten
firmly.
5.
Replace the bowl seal (do not use oil or grease as they can damage the o-rings in the valves.
6.
Install bowl into body and tighten collar firmly with your hands.
7.
Reconnect the air hose and turn on the house air supply.
8.
Close the ink enclosure door.
