General safety precautions ▪ Charge the refrigerant in liquid form. Adding it in gas form may prevent normal operation. CAUTION When the refrigerant charging procedure is done or when pausing, close the valve of the refrigerant tank immediately. If the valve is NOT closed immediately, remaining pressure might charge additional refrigerant. - Page 10 General safety precautions CAUTION ▪ When connecting the power supply: connect the earth cable first, before making the current-carrying connections. ▪ When disconnecting the power supply: disconnect the current-carrying cables first, before separating the earth connection. ▪ The length of the conductors between the power supply stress relief and the terminal block itself MUST be as such that the current-carrying wires are tautened before the earth wire is in case the power supply is pulled loose from the stress relief.

Piping installation ▪ Do NOT use flux when brazing copper-to-copper refrigerant piping. Use phosphor copper brazing filler alloy (BCuP-2: JIS Z 3264/, BCu 93P-710/795: ISO3677), which does not require flux. Flux has an extremely harmful influence on refrigerant piping systems. E.g., if a chlorine-based flux is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will deteriorate the refrigerant oil. - Page 55 Piping installation f Unit NOTICE Make sure to insulate all refrigerant piping.
