6. DESCRIPTION OF OPERATION
Fluid flow paths
Fluid enters the filter through the inlet connection into the valve by the means of the
machine system pressure. The valve directs the flow to one of the reservoirs, according to
the user set position. First, the oil is pushed from outside to in through a filter element,
which collect the dirt particles. After that, the oil is pushed through a water separation
element, which separates water from the oil. The oil (red arrows) exits the filter through the
outlet connection. The water (blue arrows) trickles from the surface of the separation
element to the bottom of the filter bowl.

7. INSTALLING AND COMMISSIONING
Before installation, make sure that all components are in proper
condition and that all required parts are at the installation site.
7.1. Transporting and storing
Follow these guidelines for transporting and storing:
•Keep the device away from excessive temperature variations and corrosive
chemicals.
•Keep the device and accessories dry.
•The device must be kept safe from mechanical effects, hits, excessive static loads
and their transport must be performed without deforming or damaging the
device/packaging.
•When transported the device/packaging must be secured in a fixed position and
should not be transported together with sharp objects.
7.2. Precautions
When installing the system, pay special attention to the following:
•Installation base shall be level and even.
•Supporting bracket or piping may not cause any stresses on the filter (twisting,
pulling, etc.).
•Sufficient space is available for installation work (Cf. Installation Drawing).
•Uncoupled accessories like sensors, gauges, etc. are properly connected
•All screws and connections are properly tightened.

8. USE OF SYSTEM
Before using the system, make sure that it does not cause any danger to
persons or the environment.
8.1. Precautions
Before using the filter, make sure that the filter bowls are properly closed and all
connections tightly fastened.
8.2. General use of the filter
Do not exceed specified pressure limits.
Check the differential pressure over the filter at regular intervals.
In normal operation one chamber is filtrating and the other chamber is on idle.
It is also possible to use both chambers for filtrating. In this case the spool should be in the
middle position (the arrow head of the handle pointing downwards).
IMPORTANT NOTICE! Pressure measuring connections in the filter
housing above the spool ARE NOT WORKING in middle position. If the
middle position will be used, filter pressure drop indication have to be
carried out by the means of external indication devices.

9. MAINTENANCE OF THE SYSTEM
Always use proper tools and lifting devices with sufficient capacity.
Replace damaged or defective equipment or lifting devices without delay
There is hot fluid inside the device, and the outer surfaces of the device
also become hot. Do not touch the device or attempt to open the filter
without proper protection.
Do not change any settings of the system unless instructions are
provided in the manual or without authorization from the manufacturer.
Never exceed any of the pressure values given by the manufacturer.
All parts replaced in conjunction with maintenance or repairs shall be
original spare parts.
Remember the following notes and warnings concerning pressurized
fluids:
•Components and hoses contain high-pressure oil
•High-pressure oil sprays can penetrate the skin and cause severe internal damage. In
case of accident, contact a physician without delay.
•Oil is hot and will cause burns on the skin.
•High-pressure oil leaks are not necessarily visible. Do not examine the system for leaks
with bare hands, use a piece of cardboard or other equivalent material.
•Before any connections are opened, the system must be made pressureless.
•Clean all connections and components in conjunction with maintenance work.
•Check all connections for tightness.

9.1. Replacing the filter elements
Before opening the filtration chamber make sure of the system is
pressureless.
Filter elements have to be replaced by using original Parker Hannifin filter elements.
1. Make sure that the spool is position that the
chamber to be serviced is idling. Turn the
spool if needed.
2. Open the venting valve carefully.
3. Drain the filter housing by opening the
draining valve.
4. Loose the screws and turn the clamp.
5. Take the filter bowl and the filter element of.
6. Assemble the filter in reverse order. Make
sure that the filter element is right way round
and the o-ring seal is in its place. Put the
element in to the bowls and lift the
bowl/bowl clamp up. Tighten the screws
evenly, max half round of each bolt at a
time. Tightening torque 40Nm.
7. Venting
On suction side installation connect filling
pump to filling connection. Open the vent
valve and fill the chamber. When fluid comes
out from the venting pipe, close vent valve.
On pressure side installation turn spool
slightly (~30°). Open vent valve(s) carefully.
When fluid comes out from the venting pipe,
close vent valve(s). Return the spool to the
locked position.

9.2. Replacing the filter spool sealing
Before opening the filtration chamber make sure of the system is
pressureless. Also make sure that no one may start the system during
the service.
1. Open the venting
valves carefully to
make sure that the
system is
pressureless.
2. Filter can be drained
from the bottom to
minimize oil leakage
from the housing when
the spool has been
removed.
3. Remove the spool
locator from handle. It
is not necessary to
detach the handle.
4. Remove the spool
holder(s).
5. Remove the spool with
sealing.
6. Change the sealing.
7. Assemble the filter in
reverse order.
