安装在墙
直通式加热器应在墙上固定好:若需要,可固定在下方调
节螺钉上。
加热器与墙壁间的间隙大小可调整,墙壁上若有凹凸不平
之处可进行调整使机器保持平坦的位置。
套管必须紧密地围绕著连接电缆。在安装加热器时,如果
损坏到此套管,则须把破洞密封好,使其不透水。
IV.
连接供水管
必须排尽直通式加热器中之空气。进行排气时先完全打开
热水龙头,以让水流流贯过热水器,此过程须持续一分钟
左右。
在机器的供水管道中一定要安装限流器。
V.
接上连接电缆
主电源线连接可安装在上方或下方。连接电缆的绝缘层应
进入机器内部至少 40 mm 深。
安装须知
对不是将插头插上即可使用的机器要首先进行安装,安装
工作需要由供电公司或者有登记注册的专业公司实施,如
果安装工作需要有供电公司的批准,则负责安装工作的专
业公司可以帮您征得供电公司的安装许可。
VI.
启动
本机器符合 IEC 61000-3-12 标准的要求。
在水管低水压且多几个冷水龙头同时开启的情况下,请您
检查机器的增强加热段"II"是否会自动起动。若否,请您
拆除流量限制器(参见附加说明 A)。
请向用户说明直通式加热器的操作方法。
A B
附加说明
如果建筑内水管水压太低而造成加热器不能以全功率工
作,则应拆除流量限制器(图 A, 3.)。
与保温加热器并列使用时,此直通式加热器应优先配线
