Products
IMPORTANT
In ordertohave maximu m benefit from your C JC F ilter, we suggest that you read through this
manu al's sections concerning installation and operation prior to the p roduct's installation, and
when the p roduct is operated or serviced.
Do not hesitate to contact C.C.JENSEN
A/S
or your local CJC distributor for any further tech
nical information you may require.
This manual contains information on the installation, operation, and maintenance of the CJC
Filter unit based on the specifications of the unit when delivered from our factory.
The
produ ction n o. is stated on the front page.
ncase post-delivery alterations have been m ade
to the unit, we recomm end that you contact C.C .JENSE N A/S or your local distributor for an
updated manual.
When ordering spare parts or requesting technical assistance, always state the production
(serial) number of the CJC filter unit (see front page of manual and name plate on unit).
Unless special permission has been granted by C.C.JENSEN A/S do not attempt to repair or
dismantle the CJC Filter unit or any of its com ponen ts within the warranty period of the unit
(with exception of any dismantling necessary for the replacement of filter elements). Failure
to seek the said perm ission will cause the guarantee on the said parts to b e void
C.C.JENSEN A /S ' product liability does not cover technical modifications to the filter unit
or its electrical system unless C.C.JENSEN A /S ' in writing has accepted such extension of
liability.

Operating Instructions for CJC Filter Products
t^ W ARNINGS & CAUTIONS
- health and safety hazards
The C JC Filter unit is a mach ine and as such it must b e inspected daily - even if CJC Filters
in general demand very little maintenance.
Almost all types ofoil are potential threats to the environmen tand as such theym ust not
be drained into ordinary sewers or "dumped" in nature. Always check that all oil carrying
components are sealed and tight before operating the CJC filter unit.
Be aware that
oil spillage
on the floor around the filter unit is a
serious safety risk
Water drained from a filter separator is not clean
an d
must not
be drained to ordinary
sewers, but be collected in a special container and disposed of in accordance with local
regulations for oil and chemical waste.
Used filter elem entsvery oftencontain harmful substancesseparated from the oil. Always
pack and seal used elements thoroughly until they can be
disposed of in accordance with
local regulations for oil and chemical waste.
The electrical power supply to the filter unit must be switched off (remove fuses if
necessary) w hen carrying out mainten ance, and especially before o pening the control box or
the terminal box of the electric motor/Repairs of the electrical control systems
may only
be
carried out by trained C.C.JEN SEN technicians.
Do n o t expose the filter unit to ambient temperatures higher than 60 C (140 F) as this
may harm electrical wires, hoses and other rubber or synthetic components
The fluid temperature inside the filter unit m ust never exce ed 80 C (175 F). Hig her fluid
tempe ratures may cause dam age to the seals and packings on and in the filter unit.

Operating instructions ^1
When ordering spare parts, always state
filter type, production no. and an exact
description of the part(drawing and item no.
ifany).
All item nos. mentioned below refer
to
drawing
nos
A) 76 021 01-6 (General arrangement)
B) 46 020 01-3 (Assembly draw ing)
in this book.
Connection to the System
CJC fine filters must be connected to the main
system by independent suction and return lin es.
The filter suction line should be connected to
the lowest and most contaminated location of
the system tank (very often the bottom drain
plug), and the filter outlet (return) line should
be led back into the tank close to the suction
pipe of the system pump - preferably below the
oil surface to avoid oxidation of the oil.
The connection pipes and hoses should be as
short as possible. If conditions on the installa
tion site demand for very long pipes the inner
diameter of the piping must be increased
accordingly and not reduced until immediately
before entering the filter.
.Note Never use fittings with tapered thread in
filter or pump.
The electric motor and the pump are connected
to the voltage required, preferably over a m otor
overload protection (not included in the CJC
standard supply). Rem ember to check at start up
that the electric motor rotates in correct
direction (indicated by arrow on fan cover).
Starting Up
Check th at inlet and outlet valv es (if fitted) are
open, and tha t the vent screw (B-7) on the filter
top is open. Then start the pump.
Close the vent screw as soon as liquid is
appearing under it (the pump will take some 15
min s to fill the filter).
Vent the filter again after approximately one
hour's operation (not necessary if filter is fitted
with automatic vent).
Normal Operation
When the filter is put into operation with a
clean filter insert, the pressure drop over the
insert (B-17) is insignificant.
Man ual no. FH7602101(-uk)
HDU 27/- P
The pressure gauge (A-3) m onitors the pressure
drop over the filter insert. The pressure varies
with the oil viscosity, bu t is usually < 0.3 bar. It
is not unusual, however, for the pressure to be
somewhat higher during the first hour of
operation until temperature and flow con ditions
have stabilized.
As impurities are deposited in and on the filter
insert the resistance against the oil flow
increases, which is monitored on the pressure
gauge. When th e pressure reaches 2 bar the free
flow area of the insert has been reduced to an
extent that the insert must be replaced. For
additional safety a 2.8 bar pressure relief valve
is integrated in the filter pump.
Filter Insert Replacement
When the gauge indicates a pressure drop of 2
bar the filter insert is due for replacement.
Before this can be done the filter housing has to
be drained.
Stop the pump and close inlet and outlet valve
(if any).Untighten the vent screw and drain the
housing through.the bottom drain (A-4).
After drainage unscrew the top nut (B-23) and
lift off the housing. Unscrew the spring nut (B-
29) and remove the spring (B-24) and
the
spring
guide (B-16). Now lift up the insert. This is
done easily by means of a CJC Insert Extractor,
which can be ordered with the new filter insert.
When all inside parts have been cleaned and all
o-rings checked (B-5, B-13) the new insert can
be placed in the housing. Before pressing the
spring guide in place, check that the o-ring is
placed correctly in the groove.Take care not to
damage it on the thread of the stay bolt during
assembly.
W hen the spring guide and the spring have been
placed, tighten th e spring nut first by hand until
it touches the spring hou singdisc,and then with
a spanner an additional 4 turns per 27/27
module, making the insert settle. Refit the
housing, tighten the top nut (150 Nm) and the
filter is ready to be restarted. Remember to
close the bottom drain.
The lifetime of the filter insert is dependent of
the operating condition s. It
is
advisable, though,
to replace the insert once a year.
