(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 10 m connecting piping.
(purging is not required even for the short piping. )
If the piping length is longer, when it is 10 to 15 m, add 20 g refrigerant per meter.
The pipe length is 7.5m.
