Risk of electric shock

• Turn power off before servicing
– see instructions

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

GEH-5841

INSTRUCTIONS

High Mast Luminaire

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.

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.

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 self­tapping 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.

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.

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

2. Replace top housing and tighten bolt.

LAMP INSTALLATION

CAUTION

Risk of burn

• Allow lamp/fixture to cool before

handling

Use only lamps specified on nameplate. Observe
lamp manufacturer’s recommendations and restric­tions on lamp operation, particularly ballast type,
burning position, etc.

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.

Figure 5

LAMP TIGHTNESS: The lamp should be securely

inserted to NEMA-EEI specified torque of 35 inch­pounds, 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.

To install lamp in an enclosed luminaire, open four
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.

Optical assemblies designed for 1000 watt lamps are
equipped with a lamp support that grips the base of the
lamp. Be sure the grips are covered with fiberglass sleeving.
If sleeving is missing, replace it before relamping,

WARNING: FOR 1000 WATT HIGH PRESSURE

SODIUM LAMPS, A VOLTAGE PULSE IN EXCESS

OF 4000 VOLTS IS PRESENT AT THE LAMP

SOCKET UNDER OPEN CIRCUIT CONDITIONS.

ADJUSTMENT OF ASYMMETRICAL (UNDER)
REFLECTOR

The inner reflector is clamped to the outer reflector by
means of three screws located 120 degrees apart near the
bottom of the outer reflector. Slightly loosen these screws.
The screws have stop nuts on them to prevent the clamps
from falling off, so if a screw starts to bind, do not force it.
The inner reflector must be supported while it is being
rotated, because if the three notches in its flange line up
with the three support brackets, it will fall out.

The inner reflector is aimed by aligning the indented
degree marks with the indented line on flange of outer
reflector. Indented line on outer reflector is located
opposite hinge. Rotate the inner reflector until the desired
position is reached, then tighten the three clamping screw.

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.
