1 SAFETY CONSIDERATIONS
1.1 General
Installation, start-up and servicing of equipment can be hazardous if certain factors particular to the
installation are not considered: operating pressures, presence of electrical components and
voltages and the installation site (elevated plinths and built-up up structures). Only properly
qualified installation engineers and highly qualified installers and technicians, fully trained for the
product, are authorised to install and start-up the equipment safely.
During all servicing operations, all instructions and recommendations, which appear in the
installation and service instructions for the product, as well as on tags and labels fixed to the
equipment and components and accompanying parts supplied separately, must be read,
understood and followed.
Apply all standard safety codes and practices.
Wear safety glasses and gloves.
Use the proper tools to move heavy objects. Move units carefully and set them down gently.
1.2 Avoid electrocution
Only personnel qualified in accordance with IEC (International Electrotechnical Commission)
recommendations may be permitted access to electrical components. It is particularly
recommended that all sources of electricity to the unit be shut off before any work is begun. Shut
off main power supply at the main circuit breaker or isolator.
IMPORTANT: This equipment uses and emits electromagnetic signals. Tests have shown
that the equipment conforms to all applicable codes with respect to electromagnetic
compatibility.
RISK OF ELECTROCUTION: Even when the main circuit breaker or isolator is switched
off, certain circuits may still be energized, since they may be connected to a separate
power source.
RISK OF BURNS: Electrical currents cause components to get hot either temporarily or
permanently. Handle power cable, electrical cables and conduits, terminal box covers
and motor frames with great care.
ATTENTION: In accordance with the operating conditions the fans can be cleaned
periodically. A fan can start at any time, even if the unit has been shut down.
