See 

Figure 1

.

WARNING! Risk of personal injury

• All work with the unit must be done with the

power of the fan disconnected. Ensure that

the fan wheel is stationary.

• A rotating fan impeller can cause personal in-

jury. See 

Figure 2

. Mount the enclosed guard

net on the fan outlet (not necessary if the fan

is used for fixed mounting and is directly con-

nected to the ducting system).

WARNING! Risk of personal injury

Risk of falling objects when

mounting the MFS above head

height. Use the necessary Per-

sonal Protective Equipment.

The MFS filters are designed to be mounted in a ver-

tical orientation as standard.
For some commercial or light loading applications with

low bulk density aerosols, horizontal mounting is ac-

ceptable.
Consult your Nederman representative if there are

any questions on proper orientation.

The two included straps must be used and be

correctly fitted, if the filter is installed hori-

zontally.

1 Ensure that the surface, on which to mount the

MFS filter unit is level and that it can withstand

the weight of the system. Use the wall bracket to

mark the holes. Ensure that the inlet side points

towards the direction that the extracted air is

coming from the extraction arm duct.

2 Use vibration secured fixing bolts and nuts suit-

able for the wall material. The bolts must each

stand a torque force of minimum 2000 N.

3 Only for horizontal installation. For vertical install-

ation, continue to step 4.
• Install four bolts to loosely hold the frame in

place for installation of the two straps.

• Install the two straps over the frame of the MFS.

Position the straps to the inner side of the bolt

holes to prevent the straps from falling off. See

Figure 1

.

• Tighten the four MFS frame bolts securely. Con-

tinue to step 4.

4 Mount a Nederman fan or adapter on the ex-

haust/clean air side of the MFS filter. Ensure the

arrow on the filter points in the direction of the

fan when installed.

5 Mount a desired Nederman extraction arm on

the inlet side of the MFS filter. Ensure the arrow

on the filter points away from the inlet when in-

stalled.

6 Remove the filter test certificate from the filter

cartridge. Store the test certificate in an appro-

priate place. If your test certificate is lost, please

contact your Nederman expert for consultation.

7 Install the two rubber gaskets to the blue end caps

of the MFS console. Position the rubber gaskets so

that one end is installed to the ridge, and the other

is open to accept the filter. See item A, in 

Figure 1

.

8 Ensure the arrow on the filter points towards the

fan.

9 Only for horizontal installation. For vertical install-

ation, continue to step 

10

.

• Cradle the filter into the support straps.
• Carefully guide the filter in between the blue

end caps, and into the filter console. Adjust each

strap evenly as you guide the filter into the filter

console.

• The filter must be centred with each end cap pri-

or to installing the gaskets for proper sealing.

See item A, in 

Figure 1

. Tuck the loose ends of

the straps on top of the filter.

10 Carefully guide the filter in between the blue end

caps and into the filter console. The filter must be

centred with each end cap prior to installing the

gaskets for proper sealing. See item A, in 

Figure 1

.

11 Insert the open end of the two gaskets onto the

flange edges and fold it over the filter cartridge.

See item A, in 

Figure 1

.

12 Verify that the filter is correctly mounted, sealed

and that there are no visible leaks.

H = Recommended installation height, from the floor,

when installing the filter in direct connection with an

extraction arm. See 

Figure 4

.
