This publication provides essential information for the installation and operation of Hitachi air conditioning systems. It is intended for trained professionals and covers a wide range of Hitachi's product lines, including UTOPIA and SET FREE series.
General Information
This publication, or parts thereof, may not be reproduced, copied, archived, or transmitted in any form without prior authorization from Johnson Controls-Hitachi Air Conditioning Spain, S.A.U. Due to a policy of continuous product improvement, Hitachi reserves the right to make changes at any time without prior notice. Hitachi strives to provide accurate and up-to-date documentation, but printing errors cannot be excluded. No modifications should be made to the equipment without prior written permission from the manufacturer.
Safety
General Safety Precautions: The product must be disposed of in an environmentally correct manner according to local or national regulations. Dismantling must be performed by a professional installer due to refrigerants, oil, and other components. Contact relevant authorities for more information.
Symbols Used: The manual uses signal words like ! DANGER (indicating information related to severe personal injury or death), ! CAUTION (indicating information related to minor personal injury or product/property damage), and ? NOTE (indicating useful or explanatory information).
Refrigerant Safety: Specific warnings are provided regarding the release of refrigerants like R32 and R410A into the atmosphere due to their global warming potential (GWP). The use of unauthorized refrigerants is strictly prohibited and can lead to mechanical failures, operational errors, and safety device malfunctions. Hydrocarbon refrigerants are particularly dangerous due to flammability.
