OPERATION
Filter System Start-Up Procedure:
Prior to turning on the flow to the inlet service, please make the following checks:
1.
Check inside filter unit to be sure basket and filter bag (if applicable) are in housing and do
not require cleaning or replacement. If necessary install clean filter basket and bag
(if
applicable).
2.
Check that filter cover is securely fastened to housing. You are now ready to open the flow
to the inlet service line. Slowly open the inlet service line to approximately 25% of normal
operational flow (open slowly as not to displace filter bag inside the housing). After filter
unit is pressurized and vented, slowly open outlet service line unit valve until completely
open. Complete opening of inlet service line until desired flow rate is reached.
Once the desired service flow has been established, the filter will operate efficiently until dirty. However,
under no circumstances should more than
15 PSI Differential Pressure
through the filter be obtained.
Operating the filter unit with a high differential may cause filter bags to rupture and/or cause damage to filter
system and downstream equipment.
To prevent excessive drop through the filter unit, regular inspection of the filter media is required. Monitoring
of differential pressure through the housing can be utilized as a means of determining whether or not the filter
media needs cleaning or replacement.
When it becomes necessary to clean or replace filter media, follow the procedure outlined below:
1.
First close the flow from the inlet service line.
2.
Close the flow to the outlet service line. (In some applications closing flow to outlet is not
required.)
3.
Relieve the pressure in the filter unit.
WARNING
CONTENTS UNDER PRESSURE
Relieve Pressure in accordance
with Manufacturer’s instructions
before opening Filter Vessel.
FAILURE TO DO SO MAY RESULT
IN SERIOUS BODILY INJURY.
4.
Drain housing sufficiently to access filter basket.
5.
Remove cover by loosening the T-bolt clamp sufficiently to allow removal of the clamp
assembly, lift cover to remove.
6.
Remove filter basket and clean thoroughly, remove the filter bag (if applicable) and throw
away. (Cleaning and reusing the filter bag is not recommended.)
7.
Remove debris and sludge from inside the inlet portion of housing to avoid interference with
cover seal or flow of fluid being filtered.
