Bag Replacement
The pressure differential across the bag will remain fairly constant until the bag is approximately
80% blinded off. It is recommended that the bag be changed when the pressure differential
reaches 15 psi. However, this figure can vary with the type of filter bag. The bag manufacturer’s
data should be consulted to determine the actual pressure drop for replacement.
WARNING
: Review all precautions specific to the handling of the fluid being filtered before
changing the filter bag. A filter bag that has been .used with a hazardous liquid may contain
residual amounts of this material and should be handled with the same safeguards that
would be used in handling any hazardous and/or toxic material i.e. gloves, respirators,
protective eyewear, etc. Filter bags should be disposed of in accordance with federat state or
local laws and requirements. Failure to follow precautions may result in injury.
l. Close isolation valves to the filter.
2. Drain sump. (See WARNING above)
NOTE
: If bag has not been changed on a timely basis it may not drain. If necessary, the liquid
contents of the used bag can be poured into the replacement bag to be filtered.
3. Unscrew sump from cap. Sump will unscrew counterclockwise.
CAUTION
: Support sump at base while unscrewing to prevent dropping and possibly
damaging the sump or drain valve.
4. Remove basket assembly from sump. (See WARNING above)
5. Remove bag from basket.
6. Remove 0-ring from groove in the sump and wipe groove and 0-ring clean. Relubricate 0-ring
with food grade silicone lubricant or similar. Insert 0-ring in place and press into groove.
NOTE
: This step is important to ensure a proper housing seal. Make certain the 0-ring is
seated level in the groove.
7 Insert new bag into the basket. Form the bag to the contours of the basket_ making sure that
the bag extends fully to the bottom of the basket.
NOTE
: Make sure the filter bag overlaps the bag collar to insure a proper seal when the filter
housing is closed.
8. Screw the sump onto the cap and hand-tighten securely. Do not over-tighten.
