EN The regulators are homologated in compliance with CEI
EN 60730 standard and thereby comply with the fundamental
requisites of Directive 2006/95/CE.
The appliance combined with a pump connected by a flexible
cable, permits the regulation of the level of the liquid in which
it is immersed.
INSTALLATION
To ensure the efficient function of the appliance it is
necessary to fix the electric cable inside the tank or well as
illustrated in figures no.5 and no.6.
The length of the cable section between the fixture point of
the same and the regulator body, determines the total
extension of the float and the consequent distances between
the pump stopping and starting level. It is also necessary to
check that the float is not obstructed during its run.
During installation joins to the level regulator cable must not
be made under any circumstances.
An eventual cable join section must never be immersed in
water.
If the float is used in filling mode, the system must be
fitted with an adequate overflow device.
COUNTERWEIGHT INSTALLATION IF PRESENT IN THE
RETAIL PACKAGING
For correct counterweight installation refer to the following
procedure as illustrated in figure no.7.
1. Insert the cable into the counterweight, from the conic part,
turning it. This will result in the detachment of the plastic ring
inserted in the mouth (if necessary aid detachment by using
a screwdriver). Place the ring at the point of the cable where
the counterweight is to be fixed.
2. Fix the counterweight on the ring using moderate pressure
and turning it.
The counterweight is only provided on request.
ELECTRICAL CONNECTIONS
For correct product installation refer to wiring diagrams in
figures no. 1-2 [single function floats with ground] and figures
no. 3-4 [double function floats without ground].
The floats with dual function can be used for filling [fig. 2,4]
or emptying [fig. 1,3] according to the connections made
between the terminals of the microswitch and the cable.
Always disconnect the power supply from the main
power panel before undertaking any operations on the
float.
NOTE
When making the connections described above ensure that
the maximum motor power does not exceed the values
indicated on the level regulator.
The power supply cable is an integral part of the appliance.
Should the cable be found to be damaged the appliance is to
be replaced. Repairs to the cable itself are not possible.
The earth wire of yellow/green color must be connected to a
suitable earth terminal and the section dimension must not
be less than 1mm². The eventual terminal used must be
effectively protected against accidental slackening.

液位开关符合ＣＥＩ ＥＮ ６０７３０标准，满足２００６／９５／ＣＥ指针
液位开关通过软电缆与水泵连接，．开关部份浸入液体中
的基本要求。
控制液位。
安装
安装过程中，电缆接头不能祼露，更不能浸入水中．
为保证液位开关有效工作，应按图５和图６所示将电缆固
定在水箱或水池的某个位置．
固定位置距开关体的电缆长度确定了水泵开启和停止的
位置，应确定开关能够自由漂浮，不受其它设施影响．
浮动开关用于供水时，系统必须配置足够的溢流装置。
配重安装
配重正确安装方式见图７．
２．将配重轻轻转动套压在卡环。
１．将电缆从开口方向转动插入，同时塑料环形卡环会脱
落（如需要，可用螺丝起子撬下）．将卡环卡在配重在电
电气连接
按图１－２（带接地线单功能开关）和图３－４（无接地双功能
开关）所示正确连接安装连接。
根据接线方式，双功能开关可以用于供水（图２，４）或排
水（图１，３）。
需要时，提供配重。
浮动开关的安装检查前必须断电。
备注
接线时，务必确定水泵最大功率不超过开关标定值．
缆上的固定位置．
电缆线是开关的一部分，如果发现损坏，必须更换开关，
不能只更换电缆．
黄／绿色接地线必须与相关接地端子联接，截面积不小于
１ｍｍ２接地装置必须可靠，有效．
