Take proper measurement to strenghten by using another heat insulation at the following installing enviroment ●
(a) Environment temperature ≥ 35°C and humidity 85%.
(b) Environment temperature ≥ 25°C and humidity 90%.
Keep the distance 0.5m or more for straight part to separation tube, in order to prevent the outdoor
unit mulfunction and generation of refrigerant noise
Caution
2) Straight pipe length
A straight pipe (minimum lenght 0.5m) before separation tube is necessary in order to
