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

I. Installation
Please remove all shipping and crating materials carefully. Be sure to remove the plugs from the inlet
and outlet openings. Dispose of all crating materials safely.
The MODEL OT8/OT82 Filter unit is capable of having several different piping variations based upon
the outlet style of your unit. The inlet service line should be connected to the inlet flange or NPT
coupling located near the top of the unit.
The outlet service line should be connected to the outlet flange or coupling, located near the middle or
bottom of the unit depending upon the style of your unit.
There are two 1/4" NPT ports on the cover and one 1/4" NPT port on the shell of the MODEL
OT8/OT82 Filter unit. These ports can remain plugged or used for pressure gauges or special fittings as
your application requires.
Some installations require electrical grounding of all equipment, be sure to provide adequate grounding
where necessary.
After completing installation be sure to double check connections for integrity. Your MODEL
OT8/OT82 Filter unit has been factory pressure tested leak free, therefore, any seepage problems usually
occur from improper installation connections.
You are now ready to install the filter basket and bag. Remove cover by loosening the four cover
eyenuts. The eyenuts should be loosened sufficiently to swing free. Pivot cover up and out of the way
to access the basket.
The next step is to install the strainer or filter bag basket. If you've ordered the strainer basket option. A
basket seal is utilized which prevents unfiltered liquid from by-passing the basket.
If your installation requires a filter bag, insert bag into the bag basket making sure filter bag ring is
firmly seated inside the basket retainer plate opening. No basket seal is necessary when a filter bag is
used. For best results, be sure filter bag is installed fully extended to the bottom of the basket.
Before replacing cover assembly, inspect cover and inlet seal gasket (replacing as necessary). Close
cover and alternately tighten the four clamp assemblies evenly to ensure a leak proof seal between the
cover and housing body. Torque closure assemblies to a maximum of 60-90ft-lbs. Each installation may
have different closure bolting torque requirements to effectively seal the filter vessel cover. Many
installations require significantly lower closure bolting torque due to the variables explained below. The
suggested torque values are for reference only. They are to be used as a guideline by maintenance
personnel. These values are meant as a guideline for safe operation of the filter system at its maximum

rated pressure. Many variables affect the torque required to operate the filter vessel without leaks.
These variables include the diameter of the bolt, type and number of threads, material type and grade,
condition of the nut bearing surface and lubrication of bolt threads and nut bearing surfaces. Other
factors such as the condition of the o-rings, o-ring material, viscosity of the fluid being filtered,
operating pressures, temperature, and the closure assembly tightening procedure must also be
considered.
Your Rosedale MODEL OT8/OT82 is now ready for operation!
II. 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 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.
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 from the filter unit.

4. Drain housing sufficiently to access filter basket.
5. Remove cover by loosening the cover eyenuts. Remove cover by
loosening the four cover eyenuts. The eyenuts should be loosened sufficiently to
swing free. Pivot cover up and out of the way to access the basket.
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.)
8. Remove basket seal and inspect, replace if necessary. Clean basket seal
groove and replace basket seal (see spare parts diagram for location of basket
seal).
9. Install clean filter basket and filter bag (if applicable). Place the basket
into the filter housing, make sure the basket flange is firmly seated into the basket
collar. If applicable, insert bag into the bag basket making sure filter bag ring is
firmly seated inside the basket flange. For best results, be sure filter bag is
installed fully extended to the bottom of the basket.
10. Inspect cover gasket for cuts or other signs of failure and make sure it is
properly seated.
11. Move cover back into position, and alternately tighten the four clamp
assemblies evenly to ensure a leak proof seal between cover and housing body.
Torque closure assemblies to a maximum of 60-90ft-lbs. Many installations require
significantly lower closure bolting torque due to the variables previously
explained in Section I.
Your Rosedale MODEL OT8/OT82 Filter unit is now ready for operation. Refer to filter system start-
up procedure.
