3.3.2 Main Switch
The main switch of the ozone system is located on the front of the control cabinet.
By means of the main switch the complete voltage supply of the ozone generating system is
turned on or off.
Always turn off the ozone system and check for absence of voltage prior to carrying out
maintenance or repair work on the system!
3.3.3 Gas Detectors (Ambient Air Monitoring)
Ensure that rooms in which ozone leaks may occur are effectively monitored by means of
gas detectors with visual and acoustic indicators.
Such rooms are, for example: rooms containing ozone systems, rooms crossed with
removable ozone supplying pipelines.
Ensure that the monitoring device (measuring sensor) is positioned at a place where the
highest ozone concentration is to be expected in the event of a hazardous incident (at
ground level).
3.3.4 Technical Ventilation System
Ensure that rooms housing ozone systems are equipped with a technical ventilation system
guaranteeing an air exchange of at least three times per hour. An extraction-type ventilation
with the intake opening located directly above the floor must be installed. The ventilation
system must turn on automatically when a gas detector responds to the potential danger.
3.3.5 Door Switch
The ozone generating system is equipped with a door switches located in the electrical
cabinets. Once a cabinet door is opened during operation, the ozone system will turn off
immediately.
Do not remove or bridge the door switch at any time!
3.3.6 Protective Covers
All system components like the complete electronics, ozone generator, etc. are permanently
installed in a metal cabinet secured by a lockable door to prevent contact with the
components which could lead to severe injuries.
Do not remove or bridge protective devices during operation of the system!
If removal of any protective devices is required during maintenance or repair work, ensure
that these devices are refitted and checked immediately upon completion of the maintenance
and repair work. Only use the original mounting material of the protective devices!
