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 equip-
ment 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 accom-
panying 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.
• The hydronic installation must be carried out by
qualified personnel in accordance with applicable laws
and following standard accepted practices.
• The hydronic installation must be regularly serviced.
• Incorrect hydronic installation that does not comply
with the safety, electrical and thermal standards, as well
as lacking/poor maintenance can lead to excessive
pressures and cause piping breaks.

1.2 - Avoid electrocution

Only personnel qualified in accordance with IEC (Inter-
national 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.
IMPORTANT: This equipment conforms to all applicable
codes regarding electromagnetic compatibility.
