M-250A2 Crimef ighter Luminaire

READ THOROUGHLY BEFORE INSTALLING

WARNING

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 temperatures. 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.

GEH-5939

INSTRUCTIONS

To mount, hold luminaire approximately level and snug
up bolts (4-5 foot-pounds). If more upward tilt of front of
luminaire is needed, loosen the bolts slightly, lift luminaire
and insert it to the next set of leveling steps. If downward tilt
is needed, reverse procedure by extracting the luminaire
from the pipe to sit on a more rearward set of steps.

Once the proper level has been achieved, tighten each
bolt to 10-12 foot-pounds, alternating between bolts. If a
torque wrench is not available, correct torque may be
achieved by turning bolts two to three full turns (or until
bottoming occurs) past their “snug position’’.

INSTALLATION

CAUTION

Unit will fall if not installed properly

• Follow installation instructions

Remove power module ballast door by loosening captive
screw and opening door to a vertical position. Pull out
polarized disconnect plug which connects top housing
wiring with ballast door. Now grasp door securely in both
hands and open door further until it comes free from
hinges in top housing. This occurs at approximately 35
degrees from vertical on pole side of hinge. In this position
hinge pins will easily slide upward out of their hinge cradles
in top housing.

The pipe clamp accommodates 1 1/4 inch through 2
inch pipe. If necessary, adjust the two pipe clamp bolts so
that opening is slightly larger than pipe size being used.

Birdshield behind slipfitter clamp comes with an open­ing for 1 1/4 inch pipe. If a larger pipe size is used, detach
knockout to provide a larger opening. Insert pipe carefully
through bird-shield and into back of the luminaire until it
hits the leveling steps which stick down from top of hous­ing.

WARNING: UNDER NO CONDITIONS SHOULD
BOLTS BE TORQUED TO A LEVEL GREATER THAN
12 FOOT-POUNDS

PHOTOELECTRIC CONTROL

When used, photoelectric (PE) receptacle should be
oriented so that the word “North’’ is directed toward true
north. This is done by seating a PE control into receptacle,
lifting upward on PE control (which will lift PE receptacle
also), and rotating them clockwise until word “North’ is
directed toward true north. Then lower PE control and
receptacle to firmly seat them into position. No tools are
required to make this adjustment.

Alternatively, PE receptacle can be oriented before PE
control is installed. This is done by lifting up on rim of the
PE receptacle and rotating it until the word “North’’ is
directed toward true north. Lower PE receptacle to firmly
seat it in this position. Then install PE control.

WIRING

NOTE: Make all electrical connections in accordance

with the National Electrical Code and any applicable

local code requirements.

NOTE: Verify that supply voltage is correct by

comparing it to nameplate.

By selecting different steps, the luminaire may be
adjusted up or down with respect to pipe. A circular pad is
provided on top of housing for convenient application of
hand level.

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.

Terminals are readily accessible on terminal board and
will accept service leads ranging in size from AWG No. 14
through No. 6. Service leads (75° C minimum insulation,
90° C minimum for 200 & 250 watts) should extend

through mounting bracket approximately 9 inches. Attach
service leads to terminal board as shown on luminaire
nameplate. A wiring diagram is provided on a label in
luminaire. To change voltage of dual rated ballasts, see
luminaire nameplate and tag.

LAMP INSTALLATION

CAUTION

Risk of burn

• Allow lamp/fixture to cool before

handling

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

Open lower door by pulling forward on bottom of latch

to release it. Lower door to vertical and install proper lamp.

CAUTION: It is never necessary or advisable to
allow door to drop free and swing.

If a separate refractor goes in door, it should be installed
by aligning the notch with the tab in the side of the door.
Secure with the two latchs provided. (See figure 1)

To close door, swing it shut, hook latch bail over catch in
top housing, and press backward on bottom of latch until
latch engages.

FINAL ASSEMBLY

To replace door, hold it at an angle of approximately 35
degrees from vertical and toward pole side of hinge.
Carefully insert hinge pins into hinge and allow door to
hang free. Note that door is mechanically interlocked with
top housing in all positions except in the vicinity of removal
location. Reconnect disconnect plug to complete wiring
between top housing and door. Check for any possible
interference of any wiring with door closure. Rotate door
forward and tighten captive screw. All units: The doors are
designed to be assembled to top housing while in upright
position with gravity holding hinge pins properly in their
respective cradles. If door is to be assembled to top housing
while laying on its back, extreme care should be taken to
ensure that hinge pins are properly engaged with their
respective cradles by lifting up rear of door. Otherwise,
breakage may occur.

MAINTENANCE

In order to maintain high efficiency of reflectors and
refractors, a regular cleaning cycle should be established
with frequency dependent on local conditions. Use a mild
soap or detergent which is essentially neutral (follow
manufacturer’s recommendation; pH approximately 6 to

8), nonabrasive, and which contains no chlorinated or
aromatic hydrocarbons. Wash thoroughly, using a soft
cloth, or brush if necessary. Rinse in clean, cold water and
wipe dry.

To remove door refractor, rotate refractor latchs 90
degrees. This allows refractor to be removed. To replace,
simply reverse procedure.

To remove starting aid, grasp it near bottom at finger
grips provided and pull it straight out. To replace, push
firmly downward into position.
