INSTRUCTIONS

High Mast Luminaire

READ THOROUGHLY BEFORE INSTALLING

Use only lamps specified on nameplate. Observe lamp manufacturer’s recommendations and restrictions

on lamp operation, particularly ballast type, burning position, etc.

LAMP TIGHTNESS: The lamp should be securely inserted to 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 center contact of socket.

NOTE: Use of lubricants on lamp base or socket can cause rapid lamp failure and voids fixture warranty.

To install lamp in an enclosed luminaire, open six spring latches while maintaining a firm grip on the glass

clampband. Latches are easy to open if the two-stage technique shown in the picture is used. Pull the latch away

from the reflector as shown in Figure 3. Then place fingers between the latch and reflector (Figure 4) and snap the

latch off of the reflector flange.

DO NOT LET GO OF THE GLASS, SO THAT IT WOULD SWING FREE.

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.

INSTALLATION

CAUTION

Unit will fall if not installed properly

• Follow installation instructions

WARNING

Risk of electric shock

• Turn power off before servicing

– see instructions

1. Loosen the bolt on top of the luminaire and remove the cover.

2. Slide ballast assembly onto mounting arm as shown in Figure 1. If necessary, adjust bolts 1 through 4 (see

Figure 2) such that opening is slightly larger than mounting arm.

3. Tighten bolts 1 thru 4 (in sequence shown) until mounting bracket is in contact with mounting arm.

4. Align bolt 5 with hole in top of mounting arm and tighten until “bottoming” occurs.

NOTE: If mounting arm was not provided by GE or is an older existing GE arm, omit step 4, and after completing

Installation Instructions, refer to Drilling instructions.

5. Place a level on top edge of ballast housing and snug up bolts 1 thru 4 (4-5 foot-pounds). Unit may be adjusted

up or down 5 degrees with respect to mounting arm. If more lift on front of luminaire is required, first loosen

bolts 1 and 3 slightly, lift luminaire and re-snug bolts 2 and 4. If downward tilt is necessary, reverse procedure.

Side-to-side leveling can be accomplished similarly.

6. Once the proper level has been achieved, tighten bolts 1 thru 4 to twenty foot-pounds, alternating front to back

across diagonals of brackets as shown in figure 2.

Drilling Instructions: If mounting arm has no hole to prevent rotation of luminaire or has hole in different location,

refer to steps A thru C below.

A . After bolts 1 thru 4 have been securely tightened (step 6 of Installation Instructions), remove and retain bolt 5.

NOTE: Hole located between bolts 1 and 3 on mounting bracket should be ignored in these instructions.

B . Drill a 21/64” hole into mounting arm by using hole in mounting bracket as a guide. The threads in the mounting

bracket may become damaged but the self-tapping bolt (bolt 5) will cut new threads into the newly drilled

mounting arm, eliminating the need for threads in the mounting bracket.

C. Reinstall bolt 5 and tighten until “bottoming” occurs.

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.

1. Attach supply leads to terminal board a shown on nameplate.

2. Replace top housing and tighten bolt.

CAUTION

Risk of burn

• Allow lamp/fixture to cool before

handling

Figure 5

To close latches get them started by pressing against the pressure point shown in Figure 5, then strike that

pressure point with the heel of your hand.

Optical assemblies designed for 1000 watt lamps are equipped with a lamp support. Be sure the grips are

covered with fiberglass sleeving. If sleeving is missing, replace it before relamping,

ADJUSTMENT OF ASYMMETRICAL (UNDER) REFLECTOR

The inner reflector is attached inside of the outer reflector by means of three clamps located 120 degrees

apart inside the enclosure. Slightly loosen these clamps to allow rotation. To prevent dropping a clamp, dropping

the reflector, or damaging the screw threads, do not loosen the clamps more than necessary.

The inner reflector is aimed by aligning the indented degree marks with the arrow label on the clamp that is

opposite to the hinge. Rotate the inner reflector until the desired position is reached, then tighten the three clamps.

MAINTENANCE AND CLEANING

In order to maintain the high efficiency of General Electric reflectors and enclosures, a regular cleaning cycle

should be established with frequency dependent on local conditions.

Use a soap, cleaner, detergent, or a solution of the same (6-10 ounces per gallon of water or the

manufacturers’ recommendation) which is essentially neutral (pH approximately 6 to 8), nonabrasive, and which

contains no chlorinated or aromatic hydrocarbons. Wash thoroughly in this solution, using a soft cloth, of brush

if necessary. Rinse in clean, cold water and wipe dry.

These instructions do not purport to cover all details or variations in equipment nor to provide for every possible contingency to be met in connection with installation, operation or maintenance. Should

further information be desired or should particular problems arise which are not covered sufficiently for the purchaser’s purposes, the matter should be referred to GE Lighting Solutions.
