Physical Complaints Due To Too Much Ozone; Pain When Touching The Rotating Nozzle In Operation; Hearing Damage Due To Blowing Air Noise; Lubricant Leakage/Contamination - Dr. Escherich TAIFUN-CLEAN 014 Operating Instructions Manual

u The operator must mark the danger zone around the ioniser with a warning sign.

2.3.8 Physical Complaints Due to Too Much Ozone

When in operation, the ionisers generate small quantities of ozone. When ozone con-
centration is very high within a long continuous period of exposure, it can cause head-
ache, eye irritation, circulatory problems, etc.
u In order to avoid exceeding the permitted ozone concentration at the workplace,
the operator must provide sufficient ventilation.

2.3.9 Pain When Touching the Rotating Nozzle in Operation

If the rotating nozzle is installed in the cleaning device in such a way that persons can
come into direct contact with the rotating nozzle when in operation, we recommend
installation of suitable cover discs (see Accessory) as contact protection. Irrespective of
this measure the rotating energy of the rotating nozzle is so low that touching the ro-
tating nozzle could possibly be painful, however no danger of injury exists.

2.3.10 Hearing Damage Due to Blowing Air Noise

Blowing air of compressed air nozzles is resulting in high noise level.
Example: Standard rotating nozzle TCR-7A-070 generates a maximum noise level of
80 dBA (laterally, 1 m distance) and of 85 dBA (in front, 1 m distance) at 3.5 bar operat-
ing air pressure and barrier-free blowing (without a workpiece).
The value of generated noise level within the application is depending on operating air
pressure, built-in conditions and parts to be cleaned.
Depending on these parameters and the geometry and resonance behaviour of parts,
the resulting noise level can reach values of more than 100 dBA. Especially sharp edges
and holes of parts result in high noise levels. Direct decrease of this noise level is diffi-
cult without decline of cleaning result.
u Always wear hearing protection when the compressed air nozzles are operating.

2.3.11 Lubricant Leakage/Contamination

The bearings of the rotating nozzle are spaced apart from the active compressed air by
internal seals.
The constructive alignment and a corresponding compressed air supply routing
provide effective protection from lubricant leakage from inside the bearing or penetra-
tion of contamination.
In addition the special bearing has a reduced charge amount of lubricant.
Further sealing measures of the bearing chamber prevent loss of lubricant due to leak-
age.

2.3.12 Equipment Damage Due to an Electric Arc

High voltage is applied to coaxial plugs of AC ionisers. When the HV supply is switched
on and coaxial plugs are being plugged in or out, an arc may occur and damage the
socket of the HV supply and the coaxial plug of the AC ioniser.
