This manual contains operation and maintenance information for series DA/EDA 103, 253, 403,
633, 1003 and related specifications. For customer specific models, there are additional instructions
on those data sheets. The pressure filters listed above are intended for the filtering of liquid media.
1. Safety instructions
WARNING: Avoid injury. Read and understand this manual before operating the filter.
FAILURE TO FOLLOW THIS WARNING COULD LEAD TO DEATH, SEVERE INJURY,
OR PROPERTY DAMAGE. Eaton does not assume liability for any damage that occurs to
due misuse of equipment.
WARNING: This filter is a pressure vessel designed to operate under specific
pressure, temperature, and other engineering parameters. Follow the operating
conditions specified on each data sheet. Operating outside of these parameters can cause
damage to important pressure holding parts and sealing. Pay special attention to excess
pressure, temperature range, and operating fluid. The compatibility of filter components with
the operating fluid should always be considered before operation. USE OF
INCOMPATIBLE MATERIALS COULD LEAD TO PRODUCT FAILURE, LEAKAGE,
DEATH, SEVERE INJURY OR PROPERTY DAMAGE.
WARNING: Always wear safety goggles and gloves when working on the filter. Under
working conditions, the filter housing is pressurized. Do not try to loosen or remove any part
of the filter or the filter housing during operation. The operating fluid could escape at high
pressure and high temperatures. This does not apply to the offline vessel that is not under
operation. FAILURE TO FOLLOW THIS WARNING COULD LEAD TO DEATH, SEVERE
INJURY, OR PROPERTY DAMAGE.
WARNING: Leaking operating fluid can cause injury and burns. Equipment should be
shut down and isolated from energy sources and other equipment before any
inspection or servicing to prevent risk of shock or process fluid leakage. Do not open
the filter housing until you make sure it is not pressurized. The filter surface may be hot and
cause burns. When changing the filter, check the operating temperature before touching
any surface during operation. If you come into contact with the operating fluid, please follow
the safety instructions provided by the fluid manufacturer. FAILURE TO FOLLOW THIS
WARNING COULD LEAD TO DEATH, SEVERE INJURY, OR PROPERTY DAMAGE.
To ensure proper fit and function, only use Eaton spare parts.
2. Installation
The filter is supplied and delivered ready to be installed. The mounting position of the filter is vertical.
The filter has to be fitted with fastening screws in size and amount according to the corresponding
fastening bore holes of the filter housings. The filter should be mounted to minimize tensile forces on the
filter housing and change-over valve. The piping should be connected with flanges.
During installation ensure that:
-No dirt and no impurities of foreign fluids penetrate the filter.
-The connections for input and output are correctly attached to the pipe system.
-The pipe system is connected to the filter to minimize stress on the filter.
-Ensure the filter element is accessible for service and change out.
Clogging indicators should be installed according to the instructions on the unit specific data sheet and
the instructions in this manual.

3. Commissioning
Ensure the filter installation is complete and the system is clean before commissioning. Follow these
instructions to purge the filter before commissioning the system:
1. Before commissioning, ensure that the filter element and seals are clean and properly installed.
2. Place the switchgear lever in the middle position.
3. Fill both sides of the filter housing at the regular operating fluid flow.
4. Open the air bleed screws or connections. Connect tubes that lead to a drain pan (air-bleed
connection information can be found on data sheet 1659).
5. Allow the operating fluid to drain (reduce volume flow from 10 to 50 l/min (2.6 to 13.2 GPM)) until
it is bubble-free and flows out of both air bleeding tubes.)
6. Shut off application flow.
7. Remove the air bleeding tubes and close the air-bleed bore holes or air-bleed connections.
8. Switch to the filter housing you would like to operate first by using the switch gear lever.
9. After finishing step 7, tighten the locking screws.
After following these instructions for commissioning, the serviced filter vessel is ready for operation.

WARNING: Equipment should be shut down and isolated from energy sources and other
equipment before any inspection or servicing to prevent risk of shock or process fluid
leakage. Utilize proper application of PPE for the process conditions. FAILURE TO
FOLLOW THIS WARNING COULD LEAD TO DEATH, SEVERE INJURY, OR
PROPERTY DAMAGE.
4. Change of elements
Change the filter elements when the unit pressure differential on the clogging indicator reaches the
maximum pressure differential specified for each unit on the data sheet. Do not allow the pressure
differential to exceed 6 bar (87 psi) before replacing the elements. Follow these instructions to
change the filter element without interrupting filter operation:
1. Open the pressure balance valve.
2. Move the switchgear lever from the operating vessel to the vessel you need to service.
Switch gear instructions are located on a label on the filter vessel.
3. Close the pressure balance valve.
4. Open the air-bleed and the drain plug and connect with suitable hoses to a oil catch pan
to drain the vessel.
5. Keep the air bleed and drain plug open until no more operating fluid drains out.
6. Loosen the screws of the lid on the vessel that needs servicing and remove the filter lid.
7. Remove the filter elements.
8. Clean the filter housing. Ensure that no dirt or cleaning fluid get into the clean side
(center tube) of the filter element
9. Insert the clean filter element into the filter housing.
10. Place the filter lid back onto the filter housing and tighten the screw plugs. The screws
need to be tightened in an X pattern. Recommended tightening torques listed in the table
below:

65..70 48..52 
125..130 92..96 
11. Close the drain plugs.
12. Open the pressure balance valve until operating fluid flows out of the air bleed connection
without bubbles.
13. Close the pressure balance valve and air bleed connection.
14. Retighten the screws on the lid after the vessel was pressurized for the first time.
After following these instructions to change the filter element, the serviced filter vessel is ready for
operation.
CAUTION: Ensure the absolute cleanliness of the filter element is maintained during the
entire servicing period. No dirt or impurities should penetrate the filter. The new elements
should remain packaged until they are installed to prevent contamination. While removing
an element from the a recently out of operation filter housing, make sure the element is
fully discharged from any voltage caused by static charging during operation with certain
fluids
Do not damage element seals during servicing. All sealing have to be checked on a
regular basis to avoid leakage and potential development of an explosive atmosphere.
Any damaged seals will need to be replaced. Any damaged seals have to be replaced.
FAILURE TO FOLLOW THIS WARNING COULD LEAD TO DEATH, SEVERE INJURY,
OR PROPERTY DAMAGE.
5. Filter element cleaning
Microglass (VG) or paper (P) filter media CANNOT be cleaned and need to be replaced when it
reaches the dirt holding capacity. Wire mesh (G) filter media can be cleaned and used again. Follow
the cleaning specification for Eaton filter elements, sheet no. 21070-4 and 39448-4 to clean wire
mesh filter media.

6. Pressure difference measuring
If the filter assembly includes a clogging indicator, the indicator will measure the pressure difference
across the filter element. The method of pressure reading varies depending on the type of indicator
installed. It can be a visual, visual-electric or electronic reading. Additionally, the G ¼" (BSPP ¼")
connections from the switchgear can be used for external pressure gauges. Measuring connections
are recommended on data sheet 1650.
7. Special applications
This filter can be used in the special applications listed below. Please follow the instructions if you are
operating the filter in these environments.
Operation in explosive areas
WARNING: There are additional requirements for filters that are installed in explosive
areas. Please follow the instructions on Eaton Document No. 41269. FAILURE TO
FOLLOW THIS WARNING COULD LEAD TO DEATH, SEVERE INJURY, OR
PROPERTY DAMAGE.
