2 SAFETY
2.1 General
Installation, start-up and servicing of equipment can be hazardous if specific factors related 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.
