Rosedale Engineering Standards are the property of Rosedale Products, Inc.  A Rosedale Standard or copy thereof shall no be distributed (except with express approval of 
Rosedale Products, Inc.) to any individual or firm beyond the intended recipient firm or individual.  Firms of individuals acting contrary to the above may be subject to 
suit, ineligibility for continued or future employment, or removal from Rosedale’s “Approved Manufacturers and Specialty Contractors List”.

Before replacing cover, inspect cover seal gasket for damage, replacing as necessary.  Install cover and 
turn clockwise till seated on the o-ring.  Once initial contact with o-ring occurs, tighten approximately 
one half turn.  The application of process fluid (to wet seal) or lubricant will make it easier to install 
cover for a sufficient seal.  During the first several opening and closing cycles, there may be some 
chafing of the cover threads.  This is normal, and will cease as threads work into each other. 
 
Your Rosedale Model CR8 is now ready for operation!

Operation of Bag Filter Vessel. 

 
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 a clean filter 
basket and bag (if applicable). 

 
 

2.  Check that filter unit 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 
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.
