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 ofthe 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, then a gage
illuminator is recommended.
2. Installation
Model GL-53 illuminators are designed with a½” female NPT electrical conduit
connection. These illuminators must be installed vertically withthe conduit connection
located at the bottom. A flexible power cord can be temporarilyinstalled on the unit,
and used to test the unit. NOTE: Use caution when testing as the illuminator will
become very hot! This will enable the installer to optimize theilluminator location, with
respect to the gage. Then, a permanent power connection can be installed. Normally,
the illuminator will be installed parallel to the gage and aimedfrom the left or right
side (approximately 30°from center), 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 minutesof 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.

1. Open the illuminator housing by loosening
the three hex head cap screws on the end of the
unit that secures the Conduit/Lamp assembly in
place.
2. Carefully remove the assembly and remove
the Frosted Lamp (B) from the illuminator
housing and set aside. The lamp is 60W on 120
VAC models and 50W on 230VAC models.
3. Loosen the screw (C) from the side of the
lamp socket/conduit connector that holds the
assembly in place on the pipe nipple.
4. Take the lamp socket/conduit connector
assembly (D) off of the housing end piece and
set the housing aside.
5. Disassemble the lamp socket/conduit
connection assembly by removing the two
screws (E) from inside of the lamp socket. (Note
that there are two small washers on the
assembly screws. Do not lose these washers as
they are needed for re-assembling the
illuminator.)
7. Connect the black wire to the ‘gold’screw
terminal on the bottom of the lamp socket.
8. Connect the white wire to the ‘silver’screw
terminal on the bottom of the lamp socket.
9. Re-assemble the lamp socket/conduit
connector assembly using the same two screws
with washers inside of the lamp socket. Make
sure that the mounting plate is centered on the
lamp socket/conduit connector assembly.
10. Thread the lamp socket/conduit
connector assembly back into the bottom
of the pipe nipple and tighten the holding
screw.
11. Carefully screw the lamp into the
socket and re-assemble the bottom
assembly back onto the illuminator
housing (make sure that the gasket
between the bottom assembly and
housing is in place). Secure by tightening
the three hex head cap screws on the
bottom side of the housing.
