1. Safety Instructions
1.1. SAFETY INSTRUCTIONS
In addition to the instruction manual, this annex to the manual contains basic guidelines which must be followed during the
installation, start-up, and maintenance of this machine. Therefore, it is essential that both the installers and technical staff
responsible for the plant read this annex to the instruction manual prior to the installation, and to ensure that it is permanently
available next to the agitator or corresponding installation.
The safety instructions detailed in this section as well as all the special measures and recommendations included in the other
sections of this annex must be observed and fulfilled.
1.2. SYMBOLS USED
Danger of formation of explosive atmospheres or generation of ignition sources of potentially explosive
atmospheres
1.3. GENERAL SAFETY INSTRUCTIONS
•Read the instructions in this annex in addition to the manual before installing and starting the agitator.
•The installation and use of the agitator must always be carried out in accordance with applicable health and safety
regulations.
•All electrical work must be carried out by authorised specialised personnel.
•Check the characteristics of the motor and its control panel, especially in areas with a risk of fire or explosion (classified
areas). The technical manager or other responsible person of the company operating the system must define risk areas
(zones 0 - 1 - 2).
•When disassembling the agitator, the possible formation of potentially explosive atmospheres must be considered, and the
responsible person at the operating site must issue the corresponding safe work permits.
•Do not exceed the agitator's maximum operating conditions. Do not modify the operating parameters initially set for the
agitator without prior written authorisation from INOXPA.
•The limit values for the operating conditions in explosive atmospheres shall not be exceeded under any circumstances.
•Standard agitators are not designed to operate during tank filling or draining processes. Ignoring this may cause premature
wear of the motor bearings, resulting in a temperature increase up to levels which could be unacceptable for the respective
classified zone.
1.4. WARRANTY
Any warranty will be void immediately and lawfully and, in addition, INOXPA shall be compensated for any product liability
claims submitted by third parties in the case of non-compliance with any of the indications given in the attached annex or in
the following cases:

The agitator was selected for use in explosive atmospheres at the time of placing the order, according to
ATEX form. INOXPA is not liable for any damage that may arise if the information provided by the buyer
is incomplete or incorrect (liquid type, viscosity, RPM, classification of the potentially explosive area, gas
generated by the potentially explosive atmosphere, etc.)
The General Terms of Delivery already in your possession are also applicable.
