天普太阳能热水器使用方法是什么呢?

1、在冬季气温低于0℃的地区,太阳能热水器安装后,管路必须做好保温,以防因管路冻结而影响热水器的使用,必要时可加装电伴热带。
2、集热管经阳光空晒后内管壁温度可达250度左右,所以有光照安装后切勿补水,晚上洗浴完后立即补水最佳。
3、当溢流管有水溢出时,说明水箱已满,应立即关闭进水阀,防止水箱内热水漫溢流失。4、太阳热水器上水时,如果自来水压力过大,上水阀门不要开启过大,以免水从排气口溢出,严重者可能承压过大而涨坏内胆。
5、用热水之前,先试水温,以免水温过高烫伤。调温时应先调节冷水流量,后加热水,再微调冷水阀或热水阀直到获得满意的水温。
6、在使用电加热装置前,必须检查漏电保护器是否正常。在正常情况下,先补满水后再插电源,不可半箱水或无水空烧。
