HHH Filter media Inc. bag filter housings are intended to be installed in pipeline systems to remove unwanted solids from fluids. All HHH filters systems are designed to withstand rated pressures and are manufactured under an authorized ISO 9001:2000 program. Single bag and multi-bag filter housings should be installed only in systems where the flow can be interrupted in order to change the filter bags. Duplexed housings allow bag change out without shutting down the flow.Before installing the bag filter housing, check that the piping system operating conditions do not exceed their maximum pressure and temperature rating limit of the filter. Also make certain that the product which will be flowing through the filter vessel are chemically compatible with the materials used for the filter housing including the Orings and the filter bag media.
Receiving: Inspect the vessel after unpacking for damage that might have occurred during transit. Report any damage to the carrier and vendor immediately. Remove instructions and all temporary packaging materials. Filter Housing Installation Remove the plastic protective caps from the flanges and/or threads. Position the filter so that the fluid enters the inlet connection. Support the,
housing by mounting legs or brackets (included,
with some models, or available as an option), or,
use pipeline hangers. Connect inlet and outlet,
piping, along with any gauges, valves, or vents,,
using industry standards for proper thread or,
flange connection.
Filter Bag Installation Filter housings are not delivered with the filter,
bags installed, they must be installed as follows:,
Open the cover. Remove the bag hold down ring,
(s). If opening the housing for the first time remove,
restrainer basket and clean the inside of,
the housing to remove any shipping dust or packing,
debris. Inspect all O-rings, lubricate with,
compatible lubricant. Place the restrainer basket,
(if not already installed) into the filter housing. If,
the filter housing is fitted with an O-ring under the,
top lip of the restrainer basket, particular attention,
should be paid to ensure that this O-ring is,
correctly positioned prior to closing the housing.,
Insert the filter bag into the restrainer basket after,
first removing the label from the bag. Be certain,
that the filter bag is pushed to the bottom of the,
basket* and that the collar of the filter bag is,
pushed into the rim of the restrainer basket so as,
to achieve a tight seal.,
*Consider ordering a reusable filter bag positioning,
device to assure that the bag is easily and,
properly seated in the restrainer basket. Also,
consider ordering SENTINEL® welded filter bags,,
SENTINEL Filter Bags fit securely into place, providing,
the perfect seal.,
Single Bag Housings: The bag hold down ring,
should then be placed into the vessel. Multi-Bag Housings: Place the bag hold down,
rings over each basket and turn to secure under,
the hold down clips.,
Before closing the cover, ensure that the sealing,
surfaces along with the cover O-ring are clean,
and damage free.,
V-Clamp Adjustment:If the vessel has a V-Clamp, it should be opened,
and tightened by hand (single bag housings: turn,
handle counterclockwise to open and clockwise,
to close).
Swing Bolts: If the housing has a swing bolt cover closure, to
avoid misalignment of the cover, tighten cover
bolts in the sequence indicated in Figures 2 or 3.
Start-Up : WARNING: The piping system should be
purged of air before full pressure is applied.
1. Close the valve on the outlet of the bag filter.
2. Open the bag filter vent.
3. Slowly and partially open the valve on the
inlet of the bag filter.
4. Carefully vent all the air from the bag filter.
Close the vent when liquid begins to discharge.
5. Fully open the inlet valve.
6. Fully open the outlet valve.
The system is now in operation.
Maintenance: The filter housing does not require any special
maintenance other than cleaning with normal
use. All parts should be regularly checked for corrosion
and other damage. Install a new filter bag
at every product change or if the bag becomes
blinded. Differential pressure (the difference in
pressure before and after the filter) will reveal if
blinding has occurred. Eaton recommend changing
the filter bag at a differential pressure of 20
psi; higher levels cause inefficient operation of
the filter system and may force particulate
through the filter bag material and contaminate
the downstream liquid.
Shut-Down: Tightly close the valves near the inlet and outlet
of the filter, release the pressure in the housing
by opening the vent or drain valve. Open the
cover carefully, and remove the filter bag. Attention
should always be given to the O-rings and
sealing surfaces, ensuring that they are clean
and undamaged. Damaged O-rings should be
replaced. Eaton recommends that O-rings be
replaced each time the pressurized housing is
opened. Reused O-rings may result in a faulty
seal. Leaks from damaged O-rings or gaskets in
no way indicate defects in the system.
Multi-Bag Housing Spring Lift
The cover lifting spring mechanism is maintenance
free. If the mechanism starts to emit
noise, remove dust cover and spray in a small
amount of oil. The mechanism is balanced at the
factory for the weight of the cover. Additional
fixtures, such as gauges, can increase the weight
and make a re-adjustment necessary. Remove
the dust cover from the bottom of the spring
cover; loosen the two lock nuts. Adjust the
spring tension by simultaneously turning the two
adjusting nuts that are located above each lock
nut. Turn the nuts clockwise to increase the tension
and increase the lifting capacity. Turn the
nuts counterclockwise to decrease the tension
and lifting capacity. After making adjustments,
re-tighten the lock nuts and replace the dust
cover.
CAUTION: Despite the ease with which the
cover is lifted, the cover is very heavy. Do
not place any part of your body under the
cover while it is moving. The cover should
always be in the fully opened position before
changing the filter bag.

Bolting:
1. Place the O-ring on the surface to be sealed.
2. Bring the sealing surface into contact with the O-ring.
3. Clean bolts and lubricate them with suitable lubricant.
4. Position the bolts and finger tighten the nuts.
5. Follow bolting sequence suggested in sketches above.
6. During the initial tightening sequence, do not tighten any bolts more than 30%. Doing so may
cause misalignment of the flange and the O-ring maybe be crushed.
7. Continue bolt tightening (following sequence) until tight, making certain that the bolts have been
stressed evenly.
