Basic Safety Information
WARNING
Risk of injury or product damage through improper handling.
Please carefully read and understand the operating manual before commissioning.
Danger from ejected parts!
Make sure that no foreign objects enter the fan. Make sure that media discharged into the
surrounding area are not discharged close to people.
Danger from ejected parts!
Do not insert any objects through the opening in the U100HL-024KA-4.
Danger from rotating and pressurized parts!
Before starting work on the U100HL-024KA-4:
- Disconnect from the power supply
- Secure against restarting,
- Determine absence of voltage,
- Vent pipes and pump (depressurization)
Work on electrical equipment must only be carried out by qualified and authorized
electricians!
CAUTION
Risk of injury!
Hair can be sucked in by the flow and become coiled around the impeller.
Hair should not be worn down and untied! Use a hair net!
Risk of cutting and crushing when reaching into the rotating impeller
Only operate the U100HL-024KA-4 with pipelines connected to suction or pressure
discharge nozzles! A pipe or hose section of at least 12 cm in length must also be connected
during operation with opened suction nozzles (suction from or discharge into the surrounding

area) to prevent fingers from coming into contact with the impeller! Dismantle connections to
the suction and pressure discharge nozzles only after safe disconnection from the power
supply! Pay attention to the stopping time of the impeller.
Potential risk of burn injuries from touching the hot surface of the U100HL-024KA-4!
Do not touch the housing during operation! A protective guard should be provided to prevent
accidental contact.
NOTE
Opening the U100HL-024KA-4 housing will void the manufacturer's warranty!
The U100HL-024KA-4 is maintenance-free. Do not open the housing.
Internal and external vibrations can loosen the fixation of the U100HL-024KA-4
Use components that cannot come loose. Observe the permitted tightening torque.
Motor bearing damage due to penetrating particles or moisture
Fit a filter upstream on the suction side if the air becomes contaminated.
Risk of overheating through prevention of natural convection
The U100HL-024KA-4 is passively cooled. Observe the maximum permissible housing
temperature. Maintain a minimum distance of 60 mm on each side for heat dissipation and
cooling air intake.
Overheating through insufficient passive cooling due to a dirty housing
Regularly remove dust deposits. To clean the surface with compressed air, protect the inlet and
outlet nozzles from incoming dust, otherwise particles can enter into the bearings.
Damage to built-in materials from chemically active and corrosive gases
Operate the U100HL-024KA-4 only:
-with gases, as described in Chapter 4, “Intended Use”,
-with the values as specified in Chapter 5, “Technical Specifications”
Transport, assembly and disassembly may only be carried out by trained and responsible
personnel!

4.1 Improper Use
The following are prohibited:
- Use of the U100HL-024KA-4 in non-commercial plants;
- Use in rooms or plants where explosive gases may occur;
- Suction, conveyance and compaction of explosive, inflammable, toxic or aggressive media;
- Operation of the U100HL-024KA-4 outside the permitted threshold limits specified in Chapter 5,
“Technical Specifications”.
Unauthorized modifications to the U100HL-024KA-4 are forbidden for safety reasons.
5 Technical Specifications
NOTE
Overheating of the U100HL-024KA-4 during operation outside the permitted range for continuous
operation!
Only operate the blower within the limits specified in the pQ chart and not with closed suction or
pressure discharge nozzles. In static operation, a measuring aperture with a minimum diameter of
6 mm or 160 l/min is to be provided.
5.1 Performance Fields
The performance fields apply to continuous operation with air as the conveyed medium at a standard
density of 1.2 kg/m3 and an ambient temperature of 25°C. The working environment is upwardly limited by
a characteristic curve at a constant rated speed of 43,000 rpm with tolerances according to ISO 13348
Grade AN4.

6 Connections
6.1 Electrical Connections
WARNING
Hazard due to electrical shock!
Work on electrical devices must only be conducted by qualified and authorized electricians.
NOTE
Damage to the electronics through shorting of the connections
Any electrical connections that are not used must be sufficiently distanced from each other.
Damage to the blower through non-compliance with protection class IP67
Protection class IP67 can only be achieved with appropriate and properly fitted M16 plugs.
Damage to the electronics through the application of voltage that is too high
Only operate the U100HL-024KA-4 within the voltage range specified in “Electrical
Connections”.
5.5.1 Mounting
The U100HL-024KA-4 can:
- be mounted in any axis position.
- Secure mounting against loosening from vibrations (pay attention to the stop nuts, screw
locking, and screw pre-tension)
- Do not exceed the maximum tightening torque of 8 Nm. This is to avoid damaging the
housing.
Maintain a minimum distance of 60 mm on each side for heat dissipation.
NOTE
Risk of overheating through prevention of natural convection.
The U100HL-024KA-4 is passively cooled. Observe the permissible housing temperature.
Maintain a minimum distance of 60 mm on each side for heat dissipation and cooling air
intake.
The U100HL-024KA-4 may move during operation!
The U100HL-024KA-4 may only be operated when fully assembled or secured against
movement.
5.5.2 Sound and Vibration Dampening
- To reduce noise emission, the U100HL-024KA-4 should not be installed on sound-conducting
or sound-radiating parts (such as thin walls or sheet metal plates).
- Sound and vibration dampening intermediate layers - so-called rubber bumps - should be
provided.
Place the spring elements between lugs and the extension surface. Fasten the U100HL-024KA-4 to
the extension surface via the four lugs with four or two (for front mounting) suitable screws or nuts of
strength class 8.8 according to ISO 898.
Secure the four screws against unintended loosening caused by vibrations.
