(2) This air-conditioner is manufactured and tested in conformity with the ISO.

(3) Sound level indicates the value in an anechoic chamber. During operation these values are somewhat higher

due to ambient conditions.

(4) Select the breaker size according to the own national standard.

(5) The refrigerant quantity to be charged includes the refrigerant in 15 m connecting piping.

(purging is not required even for the short piping. )
