5.6.3Replacement of partially filled pipes type

When detector of partially filled pipes type is replaced from LF502 or LF502(FS2 type) to LF232*F, please be careful to the following points.

Installing

In the case of replacement from LF502(FS2 type):

The diameter of hole, width of installation metal fittings of LF232, an external size of the body of converter are the same. In the installation panel processing, the built-in space, a change is unnecessary.

Because switch of LF232 is the infrared switch, please avoid a place with the following factor.

Factors to impede infrared switch to operate properly

Intense light such as direct sunlight and reflected sunlight by window glass or metal plate Place where brightness changes always such as ON/OFF of lighting

Dense smoke or steam near the control panel

Those attached on the control panel such as rain (dew drop), snow, ice, mud and oil, and haze due to their attachment

Light reflecting object near the control panel, or reflecting object such as metal plate

placed opposing to the control panel

When any of above factors is considered, take a measure for the proper operation of infrared switch such as to place a cover or to secure a space for at least a person to stand in front of the control panel.

When unable to avoid above factors, operate the EMF converter removing the factor by covering the control panel by hand so that light does not shine on it, by cleaning those attached on the control panel, or by standing in-between the reflecting object and the control panel to block the light.
