PRE-INSTALLATION
FilterMax FI is for indoor installation.
FilterMax FO is for outdoor installation.
FilterMax F should be located with consideration for easy
handling of the collected dust and for convenience of
service and maintenance.
FilterMax F is usually installed on a reinforced concrete
foundation. However, installation on another structure is
also possible. When calculating for foundation or supporting
structure the following factors should be taken into conside-
ration (see technical data):
• Total weight of FilterMax F
• Max. weight of collected contamination
• Possible wind load
• Possible snow load
IMPORTANT! Location must be clear of all obstructions
such as utility lines etc. Pay particular attention to the
anchor bolt location. Anchor bolts (M16) must extend at
least 60 mm above foundation. If you intend to secure the
unit by using expansion bolts or equivalent fittings, the
concrete floor must be prepared accordingly.
For safe and reliable results assembling
work, electrical installation, use, service
and trouble-shooting should be performed
by qualified personnel. Special training may
also be necessary.
Please contact your nearest authorised
dealer or AB Ph. Nederman & Co. for
technical advice.

IMPORTANT!
• The compressed air supply pressure has
to be = 0,4 - 0,6 MPa (4 - 6 bar / 58 - 87 psi).
• The compressed air shall have a dew point
below the minimum temperature at which the
system is ment to be used.
• The compressed air supply must be both oil
and water free.
• Improper air pressure or contamination in
the compressed air can result in cleaning
valve failure, poor cleaning and filter
performance.
• Purge compressed air lines to remove debris
before connecting to the compressed air
manifold.
• Do not use thread-sealing tape after the
filter regulator.
• Quick couplings throttle the air too much
and are not recommended.
• Turn off and bleed off compressed air supply
before doing any service work.
• Do not pressurise the system if the air tem-
perature is below the minimum operating
temperature, that is -20 °C. At lower air tem-
perature the process could be started and be
in operation for a while (approx. 15 min.) after
which the system can be pressurised.

JPre-Coate Control
In some applications with FilterMax it is necessary to inject
dust. The purpose can be to reduce the fire risk or improve
cleaning of the filter cartridges. The input JP6:1 can be
used in 2 ways. When the function of the motor protection
has been chosen, the fan LED will show fixed red light.
Then you are able to choose the use of JP6:1 PULSE or
FAN with the 0/1-button. PULSE is the pre-coate mode.
If PULSE is set there will be a choise of parameters to set:
ST - Start. The initial injection time: 0, 1, 2, 3, 4, 5, 7, 10,
15, 20, 30, 40, 60 or 90 s.
IN - Injection. The injection time: 0, 1, 2, 3, 4, 5, 7, 10, 15,
20, 30, 40 or 60 s.
PA - Pause. The pause time between the injections: 0 or
20 s. 1, 2, 5, 10, 20 or 60 min.
If FAN is set JP6:1 will run in parallel with JP6:8,9 serving
as a 24 V fan start signal.

APPLICATIONS
Nederman FilterMax F separates for instance welding
fume, metal oxides, talcum, lime stone, dust
and grinding dust.
FilterMax F must not be used for separating
explosive contaminations.
Explosive dusts are dry organic dusts and some metallic
dusts. The metallic dusts are, for example, aluminium,
magnesium, titanium, chromium and fine virgin dusts of
other metals. Welding fumes from these metals are not
explosive, but grinding dust is a problem. Please contact
your Nederman representative in case of doubts.
Various combinations of semi combustible fumes/dusts
(oil, grease) and sparks can cause fires when grinding or
welding. The most important action is to prevent sparks
from entering the extraction devices. Secondly it is very
important to perform regular cleaning of the extraction
arms/devices and the duct system.
FilterMax F does not separate gases.
WARNING!
Risk of personal injury!
• In some countries the purified air must not be
recycled in the workshop if FilterMax F is used
to separate welding fume or some contaminations
that may be a health hazard.
• Use a safety filter if the air is recycled in the
workshop.
Risk of fire or explosion!
• Do not use FilterMax F to separate explosive
fume or dust.
• Connect a fire alarm to the filter controling
processor, which means the filter will stop at
a possible fire.
• Care should be taken when working with
painted or oiled material. Consult your Nederman
representative for advice.
• FilterMax F must not be exposed for burning/
glowing material.
Earth control measuring must only be done by a
person with necessary knowledge.
IMPORTANT!
All metal parts of the filter unit must be earthed
reciprocally and connected to earth. To secure
this, the following procedure must be followed.
EARTH CONTROL MEASUREMENT
When the FilterMax F has been installed and during maintenance
work the earthing shall be measured. The measuring is done
between GND1 (in the Control Box, see picture below) and the
following components on FilterMax F. Disconnect protection earth
from GND1 before measuring.
1. Inlet
2. Cleaning access point (on the inlet)

BASIC FUNCTIONS
For fan start, two alternatives are possible.
Alternative 1:
Connection to block JP6: 1 (24 V AC), for direct control
by contactor or other 24 V relay.
Alternative 2:
Connection to block JP6: 8 - 9, potential free relay
output, is used when the start equipment has its own
24 V control voltage, for example Nederman Fan Starter
(which is recommended). The complete connection is
described in the Fan Starter Instruction Manual.

Each FilterMax F can be connected to an
existing central fan or to a fan dimensioned
specially for the system.
An adequate fan can be selected from the
Nederman NCF-range. Please contact your
Nederman representative for
dimensioning the right fan capacity.
Calculated air pressure drop over
the filter is approximately 1200 Pa.

MONITORING SYSTEM, SETTINGS
CLEANING DURING OPERATION
FilterMax F is in its standard design equipped with a fully
automatic compressed air cleaning of the filter cartridges.
A piping system directs, by a system of solenoid valves,
air pulses of 100 ms into the filter cartridges. The pause
time between the air pulses is factory set at 30 s, but can
be set between 5 s and 90 s. Shorter pause time can be
used if more than 1 module is used or if FilterMax F is
used for heavy load.
RECOMMENDATIONS FOR
PAUSE TIME SETTINGS
The pause time setting depends on the size of the filter
(i.e. the number of cartridges) and the load at which the
filter is working.
• Light load - A dust that is easy to clean off the filter
cartridges, such as dry stone dust or grinding dust.
• Normal load - Applications such as welding fume or
light dusts in heavy concentrations.
• Heavy load - Typically metal cutting with laser or
plasma and heavy welding.
With light load the cleaning pressure could be reduced
to 0.4 MPa (4 bar). Check that the filter pressure drop
does not rise too quick. If so, the pause time could be
reduced with one step and the cleaning pressure could
be increased, but maximum to 0.6 MPa (6 bar).

Setting the pause time
Push the P-button until pt is shown in the display.
Set one of the following values for pause times with
the 0/1-button. tst = test position, all valves will be
opened 1 time with 1 s interval.

STARTING THE SYSTEM
1. Turn on the compressed air supply to the cartridge filter.
Adjust to 0,4 - 0,6 MPa (4 - 6 bar, 58 - 87 psi) of pressure.
Pressure of 0,5 MPa is the most typical setting for
satisfactory cleaning performance.
2. Close the regulating damper halfway, see figure,
page 16. (As an alternative the airflow can be controlled
by a Nederman FanInverter).
3. Start the fan and check fan impeller rotation. Refer to
the rotation sticker on the fan motor. Proper fan impeller
rotation is extremely important. Contact a qualified
electrician if the impeller rotation must be reversed.
4. IMPORTANT! It is necessary to adjust the airflow
to the dimensioned value using the regulating damper
(or Nederman FanInverter). The air flow can be measured
with a fixed airflow meter (or a pitot tube) and a micro-
manometer.
IMPORTANT! Too much airflow can dramatically
reduce the life of the filter element.
WARNING!
Risk of personal injury!
Stand clear of blower fan exhaust area as
debris can be exhausted and cause injury. 5. All the solenoid valves should open and close
continuously with a set interval time between each
cleaning pulse (factory set of 30 seconds).
Check operation of the solenoid valves in the following
way: Set the pause time on tst (see below). NB! This
is only a control setting and should not be used for nor-
mal operation. Start the system and count the number
of air pulses. It should be 6 pulses per module.
NB! Return the pause time to the original value
after checking.

CLEANING AFTER OPERATION
It is possible to choose cleaning after operation, that
is when the fan has stopped. This is more efficient
than cleaning during operation and is therefore
recommended. The pause time at cleaning after
operation is always 15 s.
If cleaning after operation has been chosen, one
has to set the desired number of cleaning cycles,
where one cycle means the cleaning of all filter
cartridges, that is 6, 12 or 18 cartridges, depending
on the number of modules in operation. 2 - 3 cycles
are recommended depending on the dust load
(light - normal) When cleaning after operation it is
recommended to use an after cleaning damper
(see accessories page 30).

Setting the alarm-function
Push the P-button until dL is shown in the display. Choose
any of the functions Go or StP with the 0/1-button. For fume/
dust generating processes that can’t be stopped immediately
when a fault accurs it is recommended to set Go and that a
clearly visible alarm device is installed.
Go: The system does not stop when the A-alarm is
activated, with exception for explosion/fire-alarm, motor
protection and with the access door open. The system
always stops for these functions.
StP: The system stops automatically when the alarm is
activated.
A-ALARM FUNCTION
The alarm-function is always ON when the system
operates, which means if there are negative influences on the function during operation, the alarm
will release, that is LED no. 7 will show a red fixed light.

OFF: When using remote start there is no automatic
restart when a fault has been rectified. The remote started
mashine must be stopped and the FilterMax F must be
reset by one push on the start button before a new remote
start can be done.
Aut: When using remote start there is automatic restart
when a fault has been rectified or after a power failure.

REMOTE START
It is possible to choose the functions Aut or OFF
with the 0/1-button. For most filters that are remotly
started from a machine or a process eg. it is
convenient to choose Aut.
The remote start control should be connected to JP 1 and
9 or 10 (see page 9). If remote start is used, the system
can not be stopped with the 0/1-button. The text rE is
shown in the display for a short time.

The fan motor overload protector is released.
Check the cause. Rectify the fault and reset
the motor protector. FilterMax F always stops
when the motor protector is released.
Low pressure in the compressed air supply.
FilterMax F will not start.
FilterMax F has stopped due to low compressed
air pressure (less than 0,4 MPa (4 bar)).
FilterMax F will not start until correct pressure
is resumed.
Fire alarm. Call for service technician. Check
the reason and do not start the system until
the fault has been rectified.
Possible faults (depending on how the input
has been used):
1. The pressure drop over the filter is high.
2. The air flow in the system is too low.
• Check if the filter cartridges are saturated,
change if necessary.
• Check if any damper is not open enough.
• Check the inlet for dirt. Clean if necessary.
A-alarm! Means acute problems which could disturb
the function of the system. Action should be taken as
soon as possible. Call for a service technician.
Example:
• More than 1 valve is defective or does not work.
It is displayed which valves that are defective (Err +
