nearest to strainer outlet. Then slowly open the upstream
valve nearest to the strainer inlet.

Close all vents when air is expelled.
4.
Close the two (2) valves that isolate the off-line strainer
housing.

CAUTION:
To prevent damage to the basket, DO
NOT permit the differential pressure across the
strainer to exceed 20 psi.
1.
A differential pressure increase of 5 psi over the
clean (initial) differential pressure across the strainer
indicates that the basket of the on-line strainer
housing is debris-laden and requires removal and
cleaning.
CAUTION:
To protect the operator when
draining and venting, the fluid must be piped to
a safe area. This is a requirement for all fluids
and for water with a temperature above 120˚F.
The operator should wear appropriate protective equipment
(goggles, gloves, vest, clothing etc.) consistent with the process
fluid for strainer operation and servicing.
2.
Slowly open the two (2) valves that isolate the off-line
strainer housing and slowly close the two (2) valves that
isolate the on-line strainer housing with the debris-laden
basket. This step ensures continuous operation of the
process.
3.
For the strainer housing with the debris-laden basket,
slowly open the drain and vent as provided. This relieves
the pressure and drains fluid in the basket well.
4.
When pressure is relieved and fluid drained, open the
cover of the strainer housing that contains the debris-
laden basket. Lift or swing this cover away until it is free
of basket well.

5.
Remove the debris-laden basket. Invert the basket and
wash out the debris. Direct a stream of air, water, or steam
from the exterior of the basket to the interior.
NOTE
: Do not permit the basket debris to dry, as
it would be difficult to remove and clean the
basket.
6.
Inspect the basket at each cleaning for damage (holes, tear
etc.). Replace as needed with genuine Eaton baskets.
7.
Place the cleaned or new basket into the basket well. Take
extra care to ensure that the basket ring rests squarely on
the retaining ring in the basket well.
8.
Be sure basket handle is sufficiently high to be compressed
by the cover.
9.
Inspect cover gasket or O-ring and sealing surfaces. Clean
sealing surfaces and replace gasket or O-ring as necessary
with genuine Eaton parts.
10.
Reseat the cover. Close and bolt covers (cover nuts and
studs, Bolted Cover; bolt nuts, Quick Opening Cover).
Ensure that the sealing surfaces are clean. The gasket or O-
ring is to be seated properly before tightening the cover
hardware.
11.
Close the drain and vent that were opened.
12.
Refill this newly cleaned strainer basket housing by partially
opening the two (2) valves that isolate this strainer basket
housing very slowly.
13.
Slowly fill the strainer basket housing with working fluid.
Ensure that all air is expelled from the strainer basket
housing. Opening of venting may be required.
14.
When air is expelled, close any venting that was opened.
15.
Close the two (2) valves that were partially opened to refill
the strainer basket housing. This strainer basket housing is
now off-line and is isolated from the on-line strainer
housing.
