注意事項(xiàng)

Changing the direction lf air outflow

改變出風(fēng)口吹出方向

Adjusting the angle ａnd height of Air Curtain installation, ａnd adjusting the outflow towards the outside

調(diào)整風(fēng)幕機(jī)安裝的角度及高度，并將出風(fēng)口調(diào)整偏向室外

Effective obstruction of frequent influxes of external air

時常有室外風(fēng)侵入時有效阻隔

When there is no external air influx, adjustment should be set vertical

無室外風(fēng)侵入時應(yīng)調(diào)整為垂直

Changing the speed of the Air Curtain

改變氣幕風(fēng)速

Using high grade Air Curtain machines requires the influx of external air for ‘weakest’ ａnd no air movement for ‘strongest’

使用高一等級風(fēng)幕機(jī)室 外有風(fēng)侵入時調(diào)為“zui強(qiáng)”，無風(fēng)時調(diào)為“zui弱”

Selecting timings for weak ａnd strong velocity modulation for ease of operation

選用可強(qiáng)弱調(diào)整之機(jī)種操作簡單

Attention should be paid to direction of the refraction of airflow ａnd noise when there are ’ trong ’ speeds

應(yīng)注意“強(qiáng)”速時的噪音及氣流噴射至地板之折射方向
