2. SAFETY Hazardous Voltage Circuits! DANGER! AVERTISSEMENT! Circuits à tension élevée! SAFETY INSTRUCTIONS International safety regulations have been strictly observed in the design and testing of the mini-split. Before beginning any work, carefully read all safety instructions, and always observe them when working on or with the mini-split. The installation must follow all applicable national or local standards and regulations. - Page 6 12. For all electrical work, fuse the specified cables. Connect cables tightly and clamp them securely to prevent external forces from damaging the terminal. Improper electrical connections could overheat, causing fire and/or electrical shock. 13. The unit and any solar modules must be properly grounded in accordance with local electrical and building codes.
- Page 7 NOTE: This unit contains fluorinated greenhouse gases. • For specific information on the type of gas and the amount, please refer to the relevant label on the unit itself. • Service, maintenance, and repair of this unit must be performed by a certified technician.
