MOST DWELLINGS BUILT BEFORE 1985 HAVE SUPPLY WIRE RATED 60C. CONSULT A QUALIFIED
ELECTRICIAN BEFORE INSTALLING.
GENERAL
This luminaire is designed for outdoor lighting service, and should not be used in areas of limited ventilation,
or in high ambient temperature enclosures. Best results will be obtained if installed and maintained according to
the following recommendations.
UNPACKING
This luminaire has been properly packed so that no parts should have been damaged during transit.
Inspect to confirm.
INSTALLATION
Use only lamps specified on nameplate. Observe lamp manufacturer’s recommendations and restrictions
on lamp operation, particularly ballast type, burning position, etc.
Lamp Tightness – Mogul Base Lamp:
The lamp should be securely inserted to the NEMA-EEI specified torque
of 35 inch-pounds, which is best achieved by very firmly tightening to insure application of sufficient torque.
Tightening must be sufficient to fully depress and load the center contact of the socket.
Lamp Tightness – Medium Base Lamp:
The lamp should be tightened to a light firmness sufficient to depress
the center contact.
CHECKING OUT THE SYSTEM
When the luminaire is ready for operation, turn on the power. If there is a photoelectric control, cover the
control window with some black tape or other masking. The lamp arc should strike and the lamp should reach full
brightness within a few minutes (3-4 minutes for high pressure sodium). Remove the photoelectric control
masking, and this should turn the fixture off, if installed during daylight hours.
TROUBLESHOOTING
If the fixture does not operate after installation, reread the instructions and perform the following checks.
1) Is there proper incoming power to the fixture as specified on the nameplate?
2) Is the lamp damaged? Replace with new lamp.
Is lamp seated in socket properly?
3) For models with optional photoelectric control:
a. During daylight operation, does the lamp come on when the photoelectric control window is covered?
If not, retest with a known, good lamp. If it still does not light, replace the control device.
b. During daylight operation, does the lamp go out within two minutes after the control window is
uncovered? If not replace the control device.
c. After having operated correctly in service does the lamp burn continually all day? If so, replace the
control device.
4) With high pressure sodium (HPS) lamps, the end of life failure mode is one of cycling. The lamp will come
on for a short time and then shut off. The initial on/off period may be as long as an hour or more, but will
shorten over time to as little as one minute. Replacement of the lamp will correct the cycling condition.
5) For replacement parts, contact a local authorized General Electric Company lighting systems distributor.
MAINTENANCE AND CLEANING
It will occasionally be necessary to clean the optical parts in order to maintain the light level. Frequency of
cleaning will depend on the dirt level in the area and the minimum light level which is acceptable. The reflector
should be cleaned with any suitable non-abrasive glass-cleaning solution, soap, or detergent, and rinsed with
clean water. The glassware may be cleaned with any conventional glass cleanser.
NOTE: Use of abrasive cleaners will shorten the life of any reflector surface.
The refractor door is made with slide-off hinges, and should be removed during installation and wiring to
prevent possible damage and permit better access. Customer wiring enters through the center hole in the rear
or through the ‘’ conduit hole located on the top. An easy access wiring compartment behind the reflector is
provided for electrical connection. Knockout holes are provided to permit mounting on vertical surfaces with two
or four ‘’ bolts (not provided) through the rear of the fixture. You can also attach the luminaire to a suitable surface-
mounted outlet box (3'’ or 4'’ octagon or 2x4 rectangular). The unit may be attached to the outlet box (not provided)
with two 10-24 screws approximately 3/4'’ long (not provided). An alternate method of mounting the unit over a
surface-mounted outlet box is to position the unit over the box and mount on the vertical surface as above with
two or four ‘’ bolts (not provided) through the rear of the fixture. A gasket is provided with the unit to be placed
on the back of the housing between the luminaire and the mounting surface. If additional sealing is desired, caulk
the back of the housing with generic non-hardening sealer (not provided) across the top and down both sides. For
access to the mounting knockouts and wiring compartment, remove the reflector by gently pushing downward
on the top of the reflector allowing the lip of the reflector to clear the notch in the housing. Rotate the reflector
forward and remove. After installation and wiring is complete, replace the reflector by fully inserting the bottom
edge of the reflector into the two slotted tabs in the housing. Rotate the reflector back into the housing and gently
push downward on the top of the reflector to allow the top edge to engage the notch in the housing.
WIRING
Make all electrical connections in accordance with the National Electrical Code and any applicable local code
requirements.
Verify that supply voltage is correct by comparing it to nameplate.
If unit is designated as multivolt or multiwatt, follow specific instruction.
Do not remove insulated connectors from wires not needed for required voltage connection.
Route incoming supply conductors through clips provided and maintain half inch minimum spacing from
ballast and reflector.
IF SINGLE VOLTAGE:
All single voltage ballasts are pre-wired such that user need only connect the supply conductors.
IF MULTIVOLT: (120/208/240/277 volts)
Connect the ballast lead with the insulated terminal to the desired voltage terminal as indicated on the
ballast terminal nameplate.
IF MULTIWATT:
Multiwatt ballasts are available in various combinations of wattage. See wiring instructions on wiring tag
inside the luminaire.
LAMPS
The Wallmount 175 is designed for High Pressure Sodium, Mercury and Metal Halide lamps of 175 watts and
less depending on the ballast installed.
