Warning signs:
Avoid accidents by always following the safety instruc-
tions which are specified in the manual and on the
blower.
Warning labels with symbols without text are located on
the blower. The meaning of the symbols is explained
below. If a warning label gets damaged, and is no long-
er legible, it must be replaced. New labels are available
in the spare parts list.
Read the instructions for use carefully
and pay attention to the warning texts
in the operating instructions and on the
blower.
Always turn off the power to the blower
prior to repair and maintenance and
make sure it cannot be started in error.
Never put your hand, head, or others
body parts into the blower inlet or out-
let whilst the blower is running. A seri-
ous risk of personnel injury may occur
should contact be made with any of its
moving parts by personnel or foreign
objects. ENSURE THE MULTIAIR
IS SECURLY ISOLATED PRIOR TO
ANY MECHANICAL OR ELECTRICAL
MAINTENANCE.
The blower housing gets hot during
operation. Be careful when touching.
The blower generates high noise lev-
els. Wear hearing protection if working
near the blower during operation with
open doors.

Mounting:
The Multiair blower is delivered from the factory ready
to use and needs only to be connected to the power
supply and pipes on the blower intake / outlet.
If the blower is to be moved, a forklift or similar should
be used which lifts from underneath the bottom frame.
The forks must be long enough to lift both sides of the
bottom frame.
It is important that the blower is level, otherwise the
doors may not close properly. Adjustment can be made
using the 4 adjustable feet under the bottom frame of
the blower.
Weight - please refer to the rear of the manual.
The MultiAir MA blower is designed to operate in
ambient temperatures between -20 °C to 50 °C. If the
temperature exceeds 50 °C performance and service
life will be reduced.
The MultiAir FC/FCE blower is designed to operate in
ambient temperatures between -20 °C to 50 °C. Should
the blowers operating area be within a very cold envi-
ronment, Kongskilde would recommend using a MultiAir
FCE 4000 blower with external control panel. The ex-
ternal control panel could be positioned remotely from
the blower within a more suitable environment. Should
temperature exceed 50 °C, the motor may become too
hot, causing the blower to stop automatically.
For both MultiAir MA and MultiAir FC/FCE:
Make sure the blower is installed so that it is secured
against falling and tipping over.
Make sure that there is a sufficient supply of fresh air to
the room in which the blower takes the intake air from.
Make sure that the blower is set up so that it is eas-
ily accessible for operation and maintenance. The
blower must be set up on a stable surface that is level
and horizontal to ensure that the doors close properly.
Adjust the machine feet under the blower so that they
support evenly on the ground. It is not necessary to fix
the blower to the ground or platform.
The MultiAir MA 4000 and FC/FCE 4000 blowers are
available in two versions; as clean air blowers and as
material blowers:
The clean air blowers are designed for maximum
performance with clean air (the air may contain small
particles). Material must never be passed through the
blower since this will damage the rotor and blower
housing, or possibly block the rotor.
The material blowers are designed for suction of
material through the blower, see section "Description".
The blower rotor and blower housing must regularly be
inspected for wear and damage, see section "Service
and maintenance".
