Nilfisk-Advance America IVT 1000 CR H 9 — Dustclasses, “H” class only, “Safe Pack” only

overheating of the motor and subsequent damage may occur.

“H” class only:

A “Safe Bag” system is used for the “H” class machine. The Safe Bag system consist of a dust bag approved by BIA for class “M”. The dust bag is reinforced with a mesh and incapsulated in a plastic bag.

Insert the dust bag into the container. Its flange must point at the inlet.

Now push the flange onto the inlet until it fits tight.

The plastic bag has to fit the bottom and walls of the container. Tear the edge of the bag above the edge of the container and smooth it down.

“Safe Pack” only:

Ensure that the motor and top container fits correctly on top of the safe pack unit before starting the machine. The safe pack unit is a “throw away” unit, which is manufactured to hold dust hazardous to health.

8.2— Cleaning the main filter (standard Machine)

To keep suction power at a constant level the filter must be kept as clean as possible by shaking it at regular intervals.

Dismount the motor unit by opening the stainless steel clamp.

Take the bottom plate of the filter and pull it upwards and shake slightly. Donʼt remove the hose while shaking. The filter must not be washed or brushed!

“H” class only

The system is fitted with a vacuum gauge / manometer that allows you to monitor the minimal airflow in order to guarantee an optimal air speed within the suction hose. When you lift the floor nozzle off the surface that is being cleaned and the manometerʼs needle moves from the green zone into the red one, the dust bag is full and needs to be replaced.

Attention: The level of material inside the dust bag has to be checked at regular intervals. Monitoring the level strictly by means of the manometer is not a 100 per cent guarantee that the bag is not full.

Attention: There is no device for cleaning the main filter. When the dust bag has been replaced and the manometerʼs needle does not return to the green zone, the main filter needs to be replaced as well.

8.3 — Emptying the container / changing the bag (fig. 9)

First of all, switch the motor off and wait a moment until the dust inside the machine has settled down. Then you can separate the dust collecting container from the upper part of the machine:

Switch the motor on in order to prevent dust falling down from the filter.

Open the stainless steel clamp, now lift off the upper part and let it rest on the support frame.

Replace the disposal system, the bag. Lift the upper part above the machine. Switch the motor off.

Put the upper part on the machine and secure by locking the clamp.

“H” class only: (fig. 10)

Using a Dust Safe Bag system, Dust class H Once the dust bag is full

Open the clamps and lift the upper part.

Switch the motor on in order to prevent dust falling down from the filter.

Leave the hose connected or close by shutter cap! Now lift off the upper part and replace the safe bag disposal system.

After opening the appliance detach the plastic bag lying across the bin rim carefully, press the opening together and seal it.

Detach the back of the connecting flange by briefly and firmly pressing downwards at an angle, holding the front firmly on the connection piece as you do so.

The flexible plastic-pipe joint is now visible and can be tied off securely with the plastic cable tie simply by pulling it together.

Having ensured that no dust can escape, now also detach the front part of the flange from the connection piece.

Fitting the Dust safe Bag

Place the special dust bag flat in the bin with its opening pointing towards the bin inlet.

Now slide the opening in the special dust bag on to the bin inlet as far as it will go – without any turning. Then fold the plastic bag down over the bin rim.

Now pull the part of the plastic bag overlapping the bin rim tight against the flange (before reattaching the top and bottom sections of the vacuum cleaner).

Lift the upper part above the machine. Switch the motor off.

Put the upper part on the machine and secure with locking clamp.

9 — Dustclasses

Use in compliance with the standards.

Check which dustclass your machine is suited for (see identification plate).

The machine must not be used for several categories at the same time, unless suitable accessories are used.

Dust Class “L”

(Light hazard - defined by EN 60335-2-69). This industrial vacuum is approved according to EN 60335-2-69 for category of use “L” and is fit to suck dry, non flammable and non-toxic dust with MAK>1mg/m? values; the clean air is conveyed back into the place of work.
