the electrical system from

live components at all

terminals)

2. Prevent reactivation

3. Test absence of voltage

4. Ground and short-circuit

5. Cover or restrict adjacent live parts

3 Warranty

For the assertion of warranty claims, the products must be correctly connected and operated, and used in accordance

with the data sheets. Further prerequisites are a completed maintenance plan with no gaps and a commissioning re-

port. Systemair will require these in the case of a warranty claim. The commissioning report is a component of this

document. The maintenance plan must be created by the operator, see section 12.2 Maintenance, page 13.

4 Delivery, transport, storage

Safety information

Warning: Risk from rotating fan blades

♦Prevent access by unauthorised persons by safety personnel or access protection.

Warning: Suspended loads

♦Do not walk under suspended loads.

♦Make sure that there is nobody under a suspended load.

Delivery

Each fan leaves our plant in an electrically and mechanically proper condition. We recommend transporting the fan to

the installation site in the original packaging.

Checking delivery

♦Check the packaging and the fan for transport damage. Any findings should be noted on the cargo manifest.

♦Check completeness of the delivery.

Description |3

Unpacking

When opening the transport packaging, there is a risk of damage from sharp edges, nails, staples, splinters etc.

♦Unpack the fan carefully.

♦Check the fan for obvious transport damage.

♦Only remove the packaging shortly before assembly.

Transport

Safety information

Warning: Electrical or mechanical hazards due to fire, moisture, short circuit or malfunction.

♦Never transport the fan by the connecting wire, terminal box, impeller, protection grille, inlet cone or silencer.

♦In open transport, please make sure that no water can penetrate into the motor or other sensitive parts.

♦We recommend transporting the fan to the installation site in the original packaging.

Caution: If transported without care during loading and unloading, the fan may be damaged.

♦Load and unload the fan carefully.

♦Use hoisting equipment that is suitable for the weight to be hoisted.

♦Observe the transportation arrows on the packaging.

♦Use the fan packaging exclusively as transport protection and not as a lifting aid.

Storage

♦Store the fan in the original packaging in a dry, dust-free location protected against weather.

♦Avoid the effects of extreme heat or cold.

Hazard due to loss of function of the motor bearing

♦Avoid storing for too long (recommendation: max. 1 year).

♦Check that the motor bearing functions properly before installation.

5 Description

5.1 Intended use

All KBR- versions:

• The fan is intended for installation in ventilation systems.

• The fans are exclusively intended for extract air applications.

KBR

• The fan is suitable for extracting contaminated air

(dust, kitchen exhaust).

KBR/F

• The fan is suitable for conveying contaminated air.

• The smoke extraction units KBR/F are used in case of

fire to extract smoke gases, as well as in normal

working conditions of up to 200°C.

Incorrect use

Incorrect use refers mainly to using the fan in another way to that described. The following examples are incorrect

and hazardous:

• Conveying of explosive and combustible media

• Conveying of aggressive media

• Operation in an explosive atmosphere

• Operation without duct system

• Operation with the air connections closed

• Installation outside without weather protection

5.2 Technical data

Max. ambient temperature [°C] see data sheet, available in our online catalogue.

Sound pressure [dB] see data sheet, available in our online catalogue.

Voltage, current, frequency, enclosure class, weight see name plate of the fan

The motor data can be found on the name plate of the motor, or in the technical documents of the motor

manufacturer.

The data on the name plate of the fan apply to "standard air" according to ISO 5801.

KBR

• Temperature range [°C] of transported air = -20 to 120 (This is the maximum range. For the temperature range of

your fan, please check the data sheet.)

KBR/F

• Temperature range [°C] of transported air = -20 to 200 or up to 400°C/120 min (once)
