-
The tightness depends very much on the onsite performed tightness, such as the tightening of
the AHU separations / sections, cable glands, probes, etc.
-
After completion of the work, the tightness must be checked appropriately and must be docu-
mented.
Motor:
-
The connecting cables must comply with the specification EN 60079-14 (Section 9: Potentially
explosion risks
, Part 14: Planning, selection and installation of electrical installations).
-
Standard main switches must be assembled outside the hazardous area.
Fan section
-
Belt: Use only electrically conductive, flame retardant and self-extinguishing belts (ISO 9563 or
ISO 1813).
-
Use original spare parts.
-
The operating speed specified on the technical data must not be exceeded. The maximum per-
missible fan speed must not exceed 80%.
Air filters
-
Only use electrostatic deductive filter.
-
Use original spare parts.
-
Each individual filter cell must be permanently and electrically conductively connected with a
potential equalization cable to the inner casing of the AHU.
-
To prevent the formation of
explosion risks
by stirring up of dust deposits, the equipment has
protective systems and components designed to avoid deposits of combustible dusts as far as
possible. Therefore, for all components corresponding service openings are provided.
-
The AHU must be cleaned at regular intervals to prevent dust deposits.
Heat exchangers / steam humidifiers
DANGER!
The heat exchange medium temperature and the steam humidifier surface tem-
perature specified in the technical data sheet must not be exceeded. In any
case, these must be below the maximum admissible surface temperature or tem-
perature class of the AHU. Otherwise, the specified temperature class and the
EPL: Equipment Protection Level is no longer valid, the declaration of conformity
loses its validity, and there is an acute
DANGER OF EXPLOSION!
Field devices
-
On site assembled field devices must comply the ATEX classification specified by EUROCLIMA.
-
The electrical components (switches, lights, sensors, motors, etc.) must be approved for opera-
tion when there is a risk of explosion and must be equipped with an appropriate marking.
-
The cabling must meet the relevant standards.
-
Appropriate potential equalization must be prepared.
11.5.3 Maintenance and repair
-
In addition to the information in this chapter, maintenance and repair must be carried out accord-
ing to
chapter 2.3.3 (ATEX AHUs)
and
chapter 9 (Maintenance)
. If the specifications differ, the
ATEX-specific specifications in this chapter and in
chapter 2.3.3 (ATEX AHUs)
must be given
priority.
