9. With the secondary element in place, clean or
replace the primary element. Cleaning instruc-
tions follow.
ELEMENT INSPECTION
1. Place a bright light inside the element to inspect
for damage or leak holes. Concentrated light
will shine through the element and disclose any
holes.
2. Inspect all gaskets and gasket contact surfaces
of the housing. Should faulty gaskets be evi-
dent, correct the condition immediately.
3. If the clean element is to be stored for later use,
it must be stored in a clean container.
4. After the element has been installed, inspect and
tighten all air inlet connections prior to resuming
operation.
PRIMARY ELEMENT REPLACEMENT
1. Place the element in position on the cover and
replace the locking to secure the cover and ele-
ment.
2. Install the cover/element assembly and replace
the wing nut. Tighten the wing nut so to seat the
element gasket fully.

SEPARATOR MAINTENANCE

Refer to Figure 7-3 . When the need for a separator
element replacement is indicated by the Supervisor,
use the following procedure for separator replace-
ment.
1. Remove the air receiver/separator tank lid by
removing the sixteen (16) hex head capscrews.
To assist with the removal of the tank lid, Sullair
has provided a 1"-8 nut to the top lid so it can be
removed by a 1"-8 eye bolt (which is available
from Sullair) or a similar type of lifting device.
Also, tank lid is supplied with a boom. Remove
tank lid bolts, position boom and bolt into place
(two bolts supplied).
2. Remove the round separator cover plate from the
top of the separator element.
3. Remove the old separator element and discard.
4. Scrape the old gasket material from the tank lid
mounting surface and the flanges mounting sur-
face on the tank. Be sure to keep all scrapings
from falling back inside of the tank.
5. Now install the new separator elements and
retaining ring.
USE PROVIDED GASKET(S) ONLY.
DO NOT remove grounding staple(s) from the
replacement element's gasket.
