Installation Instructions for Model GL-53 Water Gage Illuminators for

Tubular Glass Gages or Prismatic Gages

1. General Information

Model GL-53 Water Gage Illuminators are designed to improve the vision of

the water level, for plant personnel. If a tubular glass or prismatic type water

gage is installed in an area with adequate lighting, a gage illuminator may not

be required. However, if the water gage is to be viewed from a distance

greater than 25 feet, or in poorly lit areas, then a gage illuminator is

recommended.

2. Installation

Model GL-53 illuminators are designed with a ½” female NPT electrical conduit

connection. These illuminators should be installed vertically with the conduit

connection located at the bottom. A flexible power cord can be temporarily

installed on the unit, and used to test the unit. This will enable the installer to

optimize the illuminator location, with respect to the gage. CAUTION: when

testing the position of the unit, the housing will become very hot when

powered. Then, a permanent power connection can be installed. Normally,

the illuminator will be installed parallel to the gage and off to the left or right

side, to prevent obstructing the operator’s view of the water gage.

If the illuminator is to be installed with a prismatic type water gage, one

illuminator can be used for up to two sections of size 9 glass or approximately

27 inches of water gage viewing.

This illuminator can be installed outdoors.

3. Maintenance

There is no maintenance required, other than the occasional needto service

the lamp. For additional instructions, see form E178-A. As an option to extend

lamp life, we suggest an illuminator timer: model TPS-120 (for 120 VAC

supply) or TPS-240 (for 240 supply). An illuminator timer provides up to 3

minutes of operation time, by depressing a pushbutton. This results in

extended lamp life, reduced power consumption and maintenance. Consult C-

R or your local representative for additional details.
