The switching function can be changed by turning the electric upper
part by 180° (normally closed contact or normally open contact). The
state on delivery is a normally closed contact. By inductivity in the
direct current circuit the use of suitable protection circuit should be
considered. Further maintenance indicator details and designs are
available in the maintenance indicator data sheet.
We draw attention to the fact that all values indicated are average
values and do not always occur in specific cases of application. Our
products are continually being further developed. Values, dimen-
sions and weights can change as a result of this. Our specialized
department will be pleased to offer you advice.
We recommend you to contact us concerning applications of our fil-
ters in areas governed by the EU Directive 94/9 EC (ATEX 95). The
standard version can be used for liquids based on mineral oil (cor-
responding to the fluids in Group 2 of Directive 97/23 EC Article 9).
If you consider to use other fluids please contact us for additional
support.

10. Installation, operating and maintenance instructions
10.1 Filter installation
When installing the filter make sure that sufficient space is available
to remove filter element and filter housing.
-
10.2 Connecting the electrical maintenance indicator
The electrical indicator is connected via a 2-pole appliance plug ac-
cording to DlN EN 175301–803 with poles marked 1 and 2. The elec-
trical section can be inverted to change from normally open position
to normally closed position or vice versa.
-
10.3 When should the filter element be replaced?
1 . Filters equipped with visual and electrical maintenance indicat-
or:
During cold starts, the indicator may give a warning signal.
Press the red button of the visual indicator once again only after
operating temperature has been reached. lf the red button im-
mediately pops up again and/or the electrical signal has not
switched off after reaching operating temperature, the filter ele-
ment must be replaced after the end of the shift.
2 . Filters without maintenance indicator:
The filter element should be replaced after the trial run or flush-
ing of the system. Afterwards follow instructions of the manu-
facturer.
3 . Please always ensure that you have original Filtration Group
spare elements in stock: Disposable elements (PS, Sm-N, Mic)
cannot be cleaned.
-
10.4 Element replacement
1 . Stop system and relieve filter from pressure.
2 . Loosenquick-actionclamp(10bar version) or screwsofflanged
cover,remove cover,and opendrain valve.Housing completely
vented.
3 . Remove filter element from the filter housing.
4 . Check seal for damages, replace if necessary.
5 . Make sure that the order number on the spare element corres-
ponds to the order number of the filter name-plate.
Remove the plastic bag and push element over the spigot in the
filter head.
6 . 10 bar version: Close drain valve, relocate cover, and close the
quick-action clamp. Filters are automatically vented via the air
bleeder valve, the protection cap S has to be turned 2 times for
being open.
7 . 25 bar version: Close drain valve, and put the cover plate on
so that the stud bolts go into the holes of the cover plate. Make
sure not to squeeze the O-ring on the bottom side of the cover
plate. Hand-tighten the 8 mounting nuts with spring rings. Then
drawupthenutstightcrosswisewithaturn-screwSW19without
canting the cover plate. Tightening torque for mountings nuts is
50 Nm. After bringing the hydraulic unit to service de-aerate the
filter via vent-screw.

7. Installation, operating and maintenance instructions
-
7.1 Filter installation
When installing the filter make sure that sufficient space is available
toremovethefilter element and thefilterhousing.Preferably the filter
should be installed with the housing pointing downwards.
The maintenance indicator must be visible.
-
7.2 When should the filter element be replaced or cleaned?
Filters equipped with visual and electrical maintenance indicator:
During cold starts, the indicator may give a warning signal. If vacu-
ummeter shows > 0,2 bar or the electrical signal has not switched
off after reaching operating temperature, the filter element must be
replaced or cleaned after the end of the shift. Please always ensure
that you have original Filtration Group spare elements in stock: Dis-
posable elements (Mic or Sm-x) cannot be cleaned.
7.3 Element replacement
1 . Stop system and relieve filter from pressure.
2 . Unscrew nuts, turn cover counter-clockwise and pull. Unscrew
element from support.
3 . Check O-ring on the filter for damage. Replace, if neccessary.
4 . Make sure that the order number on the spare element corres-
ponds to the order number of the filter name-plate.
5 . Complete installation.
-
7.4 Cleaning methods for cleanable elements
a) Ultrasonic cleaning
Insert the contaminated suction filter element into an ultrasonic bath
for approx. 3 minutes; then rinse in clean liquid. Afterwards, blow air
into the filter from the clean side inward.
-
b) Manual cleaning
1 . Remove coarse external contamination in a separate cleaning
tank using a brush and cleaning agent.
2 . Place filter in unused cleaning liquid (approx. 20 min)
3 . Wash filter with cleaning liquid from the outside to the inside.
4 . Dry element with pressured-air from the clean side to the dirt
side; the cleaning efficiency is about 60–70%
Using either method, be sure that no dirt is entering to the clean side
of filter.

1. Features
-
-
Pumps incorporated in hydraulic systems must be protected from
coarse containments which when not removed by any other filtering
devices may gain access to tank.
-
Filtration Group suction filters, series Pi 1710, stand out for their
rugged construction and large filter surface area.
-
The filter surface is dimensioned to ensure long life at the proper
corresponding flow rate.
The installation should be ahead of the pump in the tank for optimal
protection.
-
The standard filter material is a 100 µm stainless steal wire mesh.

6. Cleaning methods
a) Ultrasonic cleaning
Insert the contaminated suction filter element into an ultrasonic bath for approximately 3 minutes, then rinse in clean liquid. Afterwars, blow
air into the filter from the clean side outward.
The cleaning effect is approximately 80-90 %.
-
b) Manual cleaning
1 . Remove coarse external contamination in a seperate cleaning tank using a brush and cleaning agent.
2 . Place filter in unused cleaning liquid (approximately 20 minutes).
3 . Wash filter with cleaning liquid from the inside to the outside. The cleaning effect is approximately 60-70 %.
-
Using either method be sure that no dirt is washed on the inside of the element.
