or reclaim oil mist, coolant, fume and steam from manufacturing operations. This
manual describes how to install and maintain your Filtermist AX unit. Please read
all instructions before commencing any installation or maintenance work. Original
instructions are in English, all other languages are translations of this.
1.Isolation from any power supply shall either be visible (visible break in the power
supply circuits) or the isolation device is actuated to the off position and physically
locked off.
2. The unit must not be operated without the case fitted.
3. At least 120 seconds must be allowed for the inner drum to stop rotating
before the case is removed.
4.Oil leaks can be a hazard. The complete Filtermist AX system should be checked
regularly for possible oil leaks. Daily visual checks of both unit and extraction duct
are recommended.
5.Contact with oils, coolants etc. can cause skin diseases. Avoid contact with skin
and eyes and wear PVC, neoprene or nitrile gloves, safety glasses and overalls when
cleaning or working on the filter.

cutting area of the machine so that mist is drawn away from the operator’s
working area.
Direct mount to machine tool - vertical

of the Filtermist unit (see the table on page 9).
Remove 4 x insert screws in
base of unit.
Fit 4 x case studs (supplied
with unit 8Nm).
Fit foam collar seal around
inlet spigot (supplied with
unit).
.
Cut extraction hole in
machine enclosure.
Drill 4 x case stud fixing
holes (see table on page 15

hole PCD).
Cut hole for oil return tube
(if required).

Mounting the unit

Fit oil return tube and position tube to drain oil back
to machine enclosure, sump or collection vessel.
Position unit and secure.
IMPORTANT! There must be no kinks or ‘U’ bends in the return tube. The
end of the tube must not be submerged.

Electrical Connection
5
Standard Filtermist motors are wound for low & high voltage and operate on
50Hz & 60Hz as shown in the table below. A connection diagram can be found
inside the motor terminal box. The motors must be connected via a 3-phase,
direct-on-line starter and isolator with suitable thermal overloads or via an
independent supply in the machine control panel.
On start-up the motor will draw current in excess of that shown on the motor
plate. Ensure that appropriate fuses are used.
IMPORTANT! The internal drum of the unit must spin in the direction
indicated by the red arrow on the warning label and must run
continuously. To correct the rotation, swap any two supply wires. It
must not be wired to switch on and off with the machine cycle. The
Filtermist unit can only be started by using the control device provided
for that purpose. This also applies when restarting the machinery after a
stoppage.

Electrical Connection
6
Recommended Overload Setting and Terminal Connection. Overloads to be set no
higher than 125% of the motors full load current.
IMPORTANT! Please note that for 230/240v, 50Hz applications, special motors are
required. For more information, contact your supplier.

Electrical Connection
7
Isolator
The unit can be supplied with an isolator and
switch complete with motor protection overload if
requested. The overload starter must be selected to
suit different sized units or voltages and current
ratings (see table on page 10). Speak to your local
Filtermist distributor for more information.
If an isolator is not requested, the motors must be connected via a direct – online
starter and isolator with suitable thermal overloads or via an independent supply
from control panel with relevant protection. The Filtermist unit must be provided
with a clearly identified, readily accessible electrical isolation point providing all-
pole disconnection which has the facility for lock-off, and positioned between
0.60 and 1.7m above the working surface.

Electrical Connection

IMPORTANT! Ensure when connecting power to the unit that excess
electrical cable is NOT wrapped around the motor.
