• Make sure the room is always sufficiently ventilated; this
applies especially to confined spaces.

Service, maintenance and repairs

• Observe the maintenance intervals given in this manual.
Overdue maintenance can lead to high costs for repair and
revisions and can render the guarantee null and void.
• During service, maintenance and repair jobs, always use
Personal Protective Equipment (PPE) to avoid injury. This
also applies for persons who enter the work area.
• Always use tools, materials, lubricants and service
techniques which have been approved by the manufacturer.
Never use worn tools and do not leave any tools in or on the
product.
• Safety features which have been removed for service,
maintenance or repairs, must be put back immediately after
finishing these jobs and it must be checked that they still
function properly.
ATTENTION!
Service, maintenance and repairs should only be
performed in accordance with directive TRGS 560 by
authorised, qualified and trained persons (skilled)
using appropriate work practices.
WARNING!
Before carrying out service, maintenance and/or
repair jobs:
- fully disconnect the product from the mains
WARNING!
Never drive over the mains cord with any device.

INSTALLATION

4.1 Tools and requirements
- screwdriver or hexagon wrench to fasten hose clamp
4.2 Unpacking
Check that the product is complete. The package should
contain:
MNF:
- portable extraction fan with 6 m mains cord (without plug)
SUS-5/160 (option):
- 5 m extraction hose Ø 160 mm with nozzle + magnetic foot
- hose clamp
EXS-5/160 (option):
- 5 m exhaust/extension hose Ø 160 mm
- hose clamp
- adapter
If parts are missing or damaged, contact your supplier.
4.3 Mounting the mains plug
The machine comes without plug.
• Mount an appropriate earthed plug, preferably a plug with
phase inverter (three-phase motor only).
WARNING!
Plug to be installed in accordance with local
requirements. This is strictly reserved for skilled and
authorised service engineers.

4.4 Connection of the hose(s)
The maximum hose length to be connected is 20 meters. Refer
to Fig. II on page 33 for the possible configurations.
A = MNF
B = SUS-5/160
C = EXS-5/160
• Define the desired configuration.
• Interconnect the hoses, if applicable, with an adapter. Fasten
each hose to the adapter using a hose clamp.
• Connect the hose(s) to the outlet and/or inlet opening of the
portable fan using a hose clamp.
In case of two or three interconnected exhaust/extension hoses,
one adapter becomes redundant.
4.5 Connection to the mains
WARNING!
Make sure the product is suitable for connection to the
local mains. Information about the connection voltage
and frequency can be found on the identification plate.
The cables must be connected in conformance with the
local rules and regulations and can only be carried out
by well qualified and authorised technicians.
• Connect the machine to the mains.
• Check the direction of rotation of the motor (three-phase
motor only).
The direction of rotation can be checked in different ways;
- using a flowmeter; airflow at the nozzle should be min. 1000
3
m /h (keep hose straight)
- by checking the sound and the air volume
If the fan is running but there is hardly any extraction, the
direction of rotation of the motor is probably wrong. A correct
direction of rotation is indicated by a high air volume at a low
sound level. The difference can be checked by inverting the
phases.
• If necessary: invert the connection of the phases.

USE

WARNING!
Never use the fan without extraction hose.
CAUTION!
Never put any object (e.g. a stick) or limb in the inlet
or outlet opening.
5.1 Control
The motor protection switch contains two push buttons:
- an ON button (black)
- an OFF button (red)
5.2 Use
Since it concerns a portable unit, it can be used at any desirable
place. Due to the magnetic foot on the nozzle of the SUS-5/160,
the welding fume can be extracted near the source.
CAUTION!
Do not position the fan in places where it is exposed to
vibrations or heat radiation from heat sources.
• Connect the portable fan to the mains.
• Position the outlet of the fan (via outlet opening or exhaust/
extension hose) outside the working area.
