2.2 Personal protective equipment

♦Wear protective equipment during all work in the vicinity of the fan.

• protective working clothes

• protective working shoes

• protective working gloves

• helmet

• goggles

• hearing protection

2.3 5 rules of electrical safety

1. Disconnect (disconnection of

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 Maintenance.

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 IV Smart |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 IV Smart

5.1 Intended use of all IV Smart versions

• The fans are intended for installation in underground and above-ground parking structures, to facilitate ventilation

and cold smoke extraction.

• For optimum operation, the jet fan must be suspended horizontally from the ceiling in such a position that intake and

outlet are unobstructed.

• The fan is suitable for conveying clean air.

5.2 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

• Installation outside

• Operation in an explosive atmosphere

5.3 Description — different types

IV Smart EC

The fan is driven by two EC motors.

IV Smart AC

The fan is driven by two AC motors.

IV Smart EC—CO — equipped with a carbon monoxide control unit

The fan is driven by two EC motors (see “IV Smart EC equipped with an EC motor”). The fan and the control unit are pre

—wired and ready for use.

5.4 Technical data

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

Max. temperature of transported air [°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.

5.5 Carbon monoxide control unit

Voltage = 100…240 VAC

Frequency = 50…60 Hz

Table 2 CO control unit components

Component Function

Fan Two fans with a 0-10 V control input and hall output, for ventilation of the

room being monitored.

CO sensor CO sensor with 4…20 mA measuring signal output that reflects a 0…300

ppm CO concentration.

External alarm device (optional) Connection of an alarm siren or alarm light

The CO control unit controls two EC fans with a 0–10 V control signal originating from a CO sensor. Both fans are con-

trolled with the same 0–10 V signal and monitored for fan failure. The CO alarm is triggered based on the threshold and

time specifications of DIN EN 50291-1.

5.6 Information on the effects of CO on humans

Warning

This CO control unit is designed to protect people from the acute effects of carbon monoxide. It cannot

prevent the chronic effects of carbon monoxide exposure. The CO control unit can not fully protect people at

special risk, such as those with particular medical conditions. In cases of doubt, consult a doctor.

The table below sets out the symptoms, the corresponding CO concentrations and lengths of time that a person needs

to be exposed to this concentration until symptoms occur.
