7 - LOCATION ■ For structures with a "special" seismic risk, please consult us. ■ Before setting up the unit in its intended location, the installer must check the following points: - The unit must be installed outdoors in an area protected from flooding. Ensure that all conditions have been taken into account (negative outdoor temperatures, corrosive atmosphere, altitude, etc.) - The ground surface or structure must be level and strong enough to bear the unit's weight. - Raise the unit if it is installed in a snowy area, in order to ensure a sufficient air intake height. -
Page 9: Installation Recommendations
8 - INSTALLATION RECOMMENDATIONS ■ Ensure sufficient devices are provided to guarantee the protection of persons and property, and to enable maintenance operations to be carried out in complete safety. ■ If a malfunction would have significant human, environmental or financial consequences, take appropriate steps to limit the effects. ■ Ensure that the installation complies with the legal texts and codes in force in the country of operation, and that it complies with the safety rules applicable to the site where it is being used (explosive atmosphere, for example). ■ If necessary, affix to the machine the hazard symbol corresponding to the fluid in accordance with current standards. ■ Install burn hazard signs wherever the internal temperature of pipes exceeds 65°C. ■ Fit safety devices to prevent the fluid temperature or pressure from exceeding the values indicated in the order. Approval for operation at higher conditions must be obtained from us. ■ The unit must be fitted with an immediately accessible emergency stop device; this visible device must allow the electrical supply to the unit and its accessories to be cut completely. ■... -
