DANGER
Vent internal pressure to atmospheric
pressure before performing any maintenance.
1. Vent internal pressure to the atmosphere. Refer to
Shutdown instructions on page 1-10.
2. Disconnect drain lines at manual and automatic
drain valves (if installed).
DANGER
A "hissing" sound while the bowl is being
removed indicates the filter has not been
properly depressurized. DO NOT continue to
remove the bowl until the filter has been
completely vented to atmospheric pressure.
CAUTION
Filter bowls may be heavy. Caution should be
taken when removing the bowl.
3. Remove the bottom bowl by unscrewing it from
the head. A strap wrench may be needed.
4. Remove the element from the filter head with a
brisk downward pull, or by working the element
back and forth and pulling down until it snaps
free. Discard the element in accordance with ap-
plicable regulations. Used elements typically hold
contaminants, such as compressor lubricants and
particulate matter.

Note: The element may be unsnapped by ∆P in
normal operation. This will not affect filtra-
tion, as the O-ring on the element maintains a
positive seal.
5. Clean accumulated debris from the bowl with
soap and water, and dry thoroughly.
CAUTION
Lubricate the O-ring with a petroleum-based
lubricant compatible with your application.
6. Lightly lubricate the new O-ring before installing
the new element.
7. Insert new element, snapping it into place with a
firm push up into the head. The element will hang
from the head until the bowl is installed.
CAUTION
Lubricate the O-ring with a petroleum-based
lubricant compatible with your application.
8. Lightly lubricate the housing O-ring.
CAUTION
Do not use a pipe wrench to tighten the filter
bowl to the head.
9. Reattach bowl to head and hand tighten. As the
bowl is threaded onto the head, supports in the
bottom of the bowl ensure a proper seal between
the element and the filter head.
10. Reattach drain lines (if applicable).
11. Record the date of the element change in a record
book or on the provided
"Maintenance Reminder"
label. A new element
change label with the up-
dated information should
be applied over the pre-
vious label each time the
element is replaced.
Restart the dryer according to the start-up instructions
on page 1-7.
