The lter unit works with a high electrical voltage. The electrical installation
must be performed by qualied electricians. Disconnect the power supply to
the lter unit before it is opened and/or before starting work on the lter unit.
Warning - Do not connect the lter unit to explosive gases!
Do not connect the lter unit to processing machines that can bring about an
explosion risk. Furthermore, the lter unit must not be connected to media
that are highly inammable without preventative measures being taken to stop
the spread of the explosion or re to the lter unit.
Caution - Read and understand the user’s manual!
Read and understand the user guide before working on the lter unit.
Caution - Qualied personnel only!
All work concerning transport, installation and maintenance must be perfor-
med by qualied personnel.
Risk of trapping injury!
Do not insert your hand into the lter unit when the fan is running. Do not
wear loosely hanging clothing near the fan when operational. These can be
sucked into the fan or get caught.
Risk of tipping over!
Always check the weight of the lter unit (technical data, heading 7) before
lifting. When equipped with an integrated fan unit the centre of gravity of the
lter unit is relatively high. When transporting the lter unit, secure well - an
alternative can be to transport the lter unit horizontally.
Heavy products!
Filter cassettes are heavy. Check the current weight of the lter cassette be-
fore handling. Weight details can be found on the lter cassette’s rating plate
and under heading 11 “Handling the lter cassettes”.
Lifting equipment or the like must be used during service and inspection
work above the ground.
Risk of slipping!
Keep the oor clean. Remove oil spill to prevent injury due to slipping.
High noise levels!
If the sound level at the control panel/workplace exceeds 75 dB(A) ear protec-
tion must be worn.
Dangerous uids!
Use requisite personal safety equipment with all types of service work, as the
lter unit can contain liquids dangerous to health. Refer to the product sheet
for the liquids in question before handling.
Caution when recirculating air back into the building!
Note that in its standard design the lter unit does not separate gas molecules.

5.1 General
When unpackaging the lter unit please check that it has not been damaged during transport.
If a claim is necessary, contact the shipper.
5.2 Transporting A•mist6C,A•mist10, A•mist20
The lter unit is delivered on a wooden pallet and is wrapped in plastic foil. A•mist10 and
A•mist20 have a high centre of gravity, so there is risk for tipping over. Secure the lter unit pro-
perly or transport A•mist10 and A•mist20 lying down. To prevent damage, allow the packaging to
remain on the sections until it is time to install them.
Because the construction of the lter units di󰀨er, there are di󰀨erent lifting instructions:
A•mist6C: Lift on truck forks or use lifting straps with spacers around the unit.
A•mist10 and A•mist20: Screw lifting eyes (accessory) into the holes at the top of the lter
unit. See g. 3.
For lifting, use one of the following methods:
Fig.1: Lifting the lter unit on
a wooden pallet with a forklift
truck.
Fig.3: Lifting a vertical lter unit
by using the lifting eyes.
Fig.2: Lifting a vertical lter unit

5.4 Transporting A•mist40T, A•mist40TF, A•mist80T, A•mist80TF
The lter unit is delivered on a wooden pallet and is wrapped in plastic foil. The A•mist40T,
A•mist40TF and A•mist80T lter units are delivered fully assembled, the A•mist80TF is split between
the lter section and the fan section and has to be assembled at the site. To prevent damage,
allow the packaging to remain on the sections until it is time to install them. The lter units
have a high centre of gravity. It is therefore important to secure the lter unit properly to the
transporter before transporting them. If they need to be lifted, do so according to any
of the following methods:
Fig.1 Use an overhead crane
to lift the lter unit stan-
ding on a wooden pallet.
Fig. 2 Use a fork-lift to
lift the lter unit stan
ding on a wooden
pallet.
Fig. 3 Use a fork-lift or an
overhead crane to lift a
lter unit that is standing.
5.5 Floor Mounting
The oor on which the lter unit is placed must be at and rm. The oor or base must be
designed so that it will support the weight of the lter unit. While mounting the lter unit and
ductwork, tubes and electric cables, allow su󰀩cient open space in front of the service doors
so that they can be opened freely (see pictures below) and that the interior components such
as the lter cassettes can be withdrawn and removed as needed.

A•mist
Contaminated air is sucked into the inlet in the bottom section of the assembled units and passes
through an Absolent lter where most of the oil particles are arrested. Before the lter becomes sa-
turated with oil, the oil is drained down to the bottom of the unit that serves as a collection vessel.
The oil is then conveyed back to the machine, to a receptacle or to a central purication system.
The air passes on through another Absolent lter, where any remaining larger particles are ar-
rested (A•mist20 and higher). The air is then sucked through a H13 HEPA, which makes it so clean
that it usually can be returned directly to the premises.
5.6 Installation
1. Place the lter unit at its point of destination and bold it to the
oor.
2. Open the service door and check that the lter cassettes are
secured. The lter cassettes are properly secured when the re-
tainer arms point upwards. If a lter cassette has become loose
during the transport, secure it and close the service door. (How
to secure: see 12.3).
3. Connect the drainage. Connect a liquid trap to the drainage
(see g 1). It is important that air is not sucked backward th-
rough the drainage so it blocks the return oil. Instead of a liquid
trap, it is possible to connect a hose that empties under the
surface of liquid in an open bucket or to an airtight receptacle.
For available liquid traps, see ”13 - Accessories”.
4. Connect the suction pipe with a control damper. When using a
branch pipe the recommended connection is a 30° elbow, as
this gives a low pressure drop for the entire installation.
5. The next step is to connect the lter unit to electricity. For more
information on handling, see 8. ”Electrical connection”.

Risk of trapping injury!
Do not insert your hand into the lter unit when the fan is running. Do not wear
loosely hanging clothing near the fan when operational. These can be sucked
into the fan or get caught.
1. Check that the lter cassettes are properly secured.
Open the door and check that the lter cassettes are properly secured, i.e. that the sealing is com-
pressed to approx. 3 mm. How to secure, se heading 12.3.
2. The fan’s direction of rotation
Make sure that the fan impeller rotates in the proper direction (counter-clockwise viewed from the
motor side). If you are unable to see the motor while the impeller is rotating, start the fan, read the
pressure drop across the lters from the pressure gauge, stop the fan, transpose two phase leads,
restart the fan and read the pressure drop again. The connection that gave the highest pressure
drop is the correct one.
Note: For A•mist20HP , the fan impeller rotates clockwise viewed from the motor side.
3. Air ow
The air ow must be checked, so that the value does not exceed the design level for the instal-
lation (refer to the quote or unless otherwise stated the nominal ow under heading “Technical
data”). The air ow can be adjusted with the damper or frequency converter, if tted. If it is di󰀩cult
to reach the required ow, check the direction of rotation of the fan motor according to section 2
above. If the unit is run with a too high ow, there is a large risk that the life span of the lter cas-
settes will be shortened.
4. Pressure drop over the lter cassettes
Read the A•monitor (A•mist60: read the analogue pressure gauges) and note down the pressure
drop over the di󰀨erent lter stages (heading 11 resp 10). These values can then be used as a basic
value to assess the pressure increase /life span of the di󰀨erent lter cassettes.
5. Spray system (if installed)
If the lter unit is equipped with a spray system its function must be checked as this has a large ef-
fect on the life span of the lter cassettes.
The function of the spray system and fault tracing are described in the separate user guide.
6. Frequency converter (if installed)
If the lter unit is equipped with a frequency converter, you nd a protocol of the di󰀨erent settings
and a description how to handle the frequency converter attached.

10.1 General
Preventive maintenance and regular service extend the life span and ensure that the lter
unit maintains its performance. Besides, you mainain a high cleaning e󰀩ciency in the indu-
strial environment.
To facilitate inspection of the lter cassette status, Absolent supplies most A•mist lter units
with an electronic pressure gauge as a standard. A•mist60 is supplied with 3 analogue pres-
sure gauges for the di󰀨erent lter stages. The di󰀨erent pressure gauges are positioned on
the front of the lter unit as shown below:

A•mist60
The pressure gauges are graduated in [Pa]
and contain green, yellow and orange sec-
tors. The lter cassette is to be replaced
when its pressure gauge has reached the
orange sector. The yellow sector is a war-
ning that the lter cassette replacement is to
be planned. For a service contact, see the
heading “Technical Support”.
If the lter stage is used with the pressure
drop within the orange sector, the lter unit
gives a reduced air volume.
Note however, that the lter unit will not be
damaged when operated with a clogged
lter stage, but the required air ow will not
be attained. Handling during service is de-
scribed under “Changing the lter”.

1) In order to get to know your new installation, the lter cassettes should be checked once a month during the rst six months the
lter unit is in use. The service interval is then adapted according to the installation in question. However, no longer than six months
between inspections. Note that when the yellow LED lights, the inspection interval must be increased as the pressure drop now in-
creases quicklier.
2) In order to get to know your new installation, the bottom section and drainage should be checked once a month during the rst six
months the lter unit is in use. The service interval is then adapted according to the installation in question.

11.1 Functional description
An electronic pressure gauge A•monitor is supplied as standard along with most A•mist
lter units. The pressure monitor is delivered factory preset and contains the following
features:
OPTICAL DISPLAY OVER EACH FILTER STAGE
The present pressure drop over each lter stage is monitored (See 11.2.)
LED INDICATION
A green LED lamp is lit as long as the lter cassette is working within the preset
pressure range. When the yellow lamp is lit, call your service contact to replace the
lter stage. When the red LED lamp is lit, the pressure drop is too high for the lter
unit and it gives a reduced air ow.
HOUR COUNTER DEVICE
An hour-counter device is also included in our standard equipment.
It measures and monitors the operation time in hours for the lter unit.
ALARM
On the transformator card, there is an alarm output that can be used for external
alarms (maximum 1A). If any of the lter stages reaches alarm level (red LED), the
alarm output closes, see 8.3).

12.1 General
Filter cassettes are heavy, especially when lled with uid after a period of use. Below is a
table of weight for the di󰀨erent lter cassettes available. The type designation of the supplied
lter cassette can be found on the rating plate located on the front of the lter cassette.
HANDLING THE FILTER CASSETTES

Warning! Use requisite personal protection equipment when performing service
work on the lter unit. Lifts or the like must be used when carrying out service work
above the ground.
12.2 Instructions for Replacing Filter Cassettes
1. Read the electronic manometer A•monitor (or the analogue manometers) and note
down the pressure drop over the di󰀨erent lter stages when the lter unit is in operation.
The lter cassettes whose LEDs light in yellow or red (or whose analogue manometers
have reached the yellow or orange zone) have to be replaced.
2. Turn o󰀨 the fan and disconnect the lter unit from electricity.
3. Open the service door.
4. Loosen the cassettes by turning the retainer arms as shown on pict. A.
5. Remove the lter cassettes you want to replace according to pict. B. When replacing
lter 1, check to see that there is no dirt on the bottom of the lter unit.
6. Check that the sealing strip on top of the lter cassette is not damaged before you
push in the new lter cassette. (pict. C).
7. Secure the lter cassette (pict. D) and
close the service door.
8. Start the fan and check the pressure drop.
Note! If the supply air has a high content of chips or shavings, inspect and clean the drain
opening upstream of the return oil tank/pump more often to prevent it from becoming clog-
ged.

12.3 Worn out lter cassettes
When the lter cassette is worn out it has to be taken care of in an environmental-friendly
way. The sheet metal casing and the aluminum separators can be recycled.
Clean ltermedia can be sent to disposal facilities, but when it contains oil and particles
from the process, local regulations for disposal or incineration need to be followed.
If the oil is washed from the cassette, it can usually be sent for landll.

12.5 Not cleanable lter cassettes
Filter cassettes which include material for smoke ltration are not cleanable. This means
that A•mist10S,A•mist20S and A•mist20HPS cassettes cannot be cleaned. Hepa lters cassettes
are not cleanable either.
12.4 To clean lter cassettes (does not apply to A•mist10S, A•mist20S and A•mist20HPS)
Filter cassette No. 1 (lowest) and No. 2 (centre) can be washed several times*). Wash with
water-based degreasing agent in a chamber washer (Figure C), max. permissible water tem-
perature: 90°C / 194°F.
After washing, the lter must be left to dry until it no longer drips before it can be used again
(Figure D). The lter continues to dry in the lter unit.
The Absolute lter is not washable and must be replaced when the pressure drop exceeds
the ”service required” level.
If you do not have a chamber washer, you can place the lter cassette in a tub lled with
water mixed with a water-based degreasing agent for 4-8 hours. Then allow the
lter cassette to nish dripping before you ush it clean with a high-pressure washer.
However be careful not to damage the separators when you spray them under high pres-
sure. The result of this cleaning method is doubtful and should therefore be tested from case
to case.
Check that the sealing strip is undamaged before you ret the lter cassette. The sealing
strip must face upward.
*)The useful life of the lter may vary after washing from comparable to a new lter to reduced, depending on
the type of impurities it is exposed to.

ACCESSORIES
13
Return Liquid Hose
The return liquid hose is designed for connection to the
return oil pipe of the lter unit. The outlet of the liquid trap
is not to discharge liquid in such a way that the liquid can
damage adjacent building elements.
Correct installation of the liquid trap is very important due
to the normal subatmospheric pressure inside the lter
unit. It must t tightly against the lter unit and the outlet
must be lower than the liquid level.

SPRAY SYSTEM
13.4
If the impurities are ”too dry” or if they contain liquid
particles with excessive viscosity (sluggish), this
drastically reduces the self-cleaning capability and
useful life of the lter unit.
To increase the liquid content in the impurities and/or
reduce the viscosity, small liquid droplets are sprayed
from a nozzle into the air.
The liquid added must be able to dissolve the
impurities separated in the lter. Water is used for
emulsions. The spray nozzle is mounted in the inlet
duct of the lter unit.
The spray nozzle is controlled by a time relay with
adjustable pause and spray period. For instructions
on safety, installation and maintenance, see the
separate instructions for use!
A•mist lter units can be supplied with a mounted
protective motor contactor.
The A•mist lters unit can be equipped with a
frequency converter with integrated pressure sen-
sor. The pressure sensor measures the negative
pressure before the lte runit and compensates for
clogged lter cassettes and other changes in the
system in order to maintain the air volume stable.
Please contact Absolent / your Absolent represen-
tative for more information.

If the process air contains gas or odour, the Hepa
(H13) lter can be substituted by a carbon lter
cassette. For A•mist10, A•mist20 , A•mist60 the carbon
lter cassette can be placed on top of the lter unit
as an additional lter stage. In this case you need to
add a carbon lter hood (see 13.3).
The standard carbon lter cassette contains 21 kg of
adsorbent (active carbon) and has the measurements
595x595x292mm.
