PERMA•GARD™ LUMINAIRE
READ THOROUGHLY BEFORE INSTALLING
THE OPERATING TEMPERATURE “T-CODE” LISTED
FOR THIS LUMINAIRE IS BASED ON THE FOLLOW-
ING BULB SIZES. USE OF OTHER THAN THESE
MAY RESULT IN A HIGHER OPERATING TEMPERA-
TURE AND COULD RESULT IN A HAZARDOUS
CONDITION.
LAMP TYPE WATTAGE BULB SIZE
HIGH PRESSURE SODIUM 70,100,150 ED 23 1/2
METAL HALIDE/MERCURY 175,250 ED28
GENERAL
This luminaire is designed for application in extremely
corrosive environments. Certain units, when properly labeled,
may be used in hazardous location environments and
outdoor saltwater marine locations as specified on the
nameplate.
CAUTION: When installing the luminaire in hazard-
ous locations check the operating temperature
limits prior to installation to be sure it conforms to
the environmental temperature restrictions and NEC
classifications.
UNPACKING
The ballast assembly, optical assembly, and mounting assembly
are separately packaged. Check to verify that the correct material
has been received. The components have been properly packed so
that no parts should have been damaged during transit. Inspect to
confirm.
INSTALLATION MOUNTING-CONDUIT
inch) by threading mounting assembly onto conduit hand
tight. Loosen locking nut until it disengages from mounting
hub and is free to move up conduit (See Figure A). This
exposes wrench flats and set screw provided on hanger hub.
Fully tighten hub onto conduit and tighten set screw to lock
hanger hub to conduit. (See Figure B).
Connect ground lead to screw provided in mounting hub.
Connect supply wires to electrical disconnect. Refasten
disconnect into mounting hub (See Figure C).

CAUTION
Unit will fall if not installed properly
• Follow installation instructions
WARNING
Risk of electric shock
• Turn power off before servicing
– see instructions
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.
NOTE: When changing voltage on reconnectable
units, move only the lead with the insulated connec-
tor.
STANCHION ARM AND WALL BRACKET
INSTALLATION
Attached stanchion arm to a matching size pipe of 1
1/4 in. or 1 1/2 in. N.P.T. and tighten set screw.
Wall bracket should be attached to a mounting surface by
using four clearance holes in bracket flange. For wiring
remove appropriate plug to gain access to wiring compart-
ment. Electrical disconnect is prewired by factory. To install
ballast housing refer to ballast assembly installation instruc-
tions.
Remove electrical disconnect from hanger hub. Fasten the
mounting assembly to matching size conduit (3/4-in. or 1-

Single Voltage Units: All single voltage ballast assem-
blies are completely wired so that user must connect
only supply conductors to electrical disconnect.
Multi-Volt Units: Multivolt units are not factory
connected for any voltage. Voltage selection must be made
inside ballast housing. To connect for desired voltage
proceed as follows;
CAUTION: Make the connections prior to installing
the unit.
• Remove captive socket cannister assembly by loosening
two nuts and rotating counter-clockwise to allow nuts to
pass through keyway slots.
• Connect black lead with insulated terminal to desired
voltage terminal on ballast as specified on label.
• Replace socket cannister assembly, being careful not to
pinch any leads, and tighten nuts to 30 inch pounds.
INSTALLATION
BALLAST ASSEMBLY
With locking nut free to slide up conduit, align ballast
assembly and mounting assembly so that support pads on
mounting hub will pass between support lugs on ballast
housing. Raise ballast assembly up over mounting hub
support pads and rotate clockwise until it drops securely
into seated position. Electrical connections will automati-
cally be made during assembly operation. Check for proper
engagement by trying to rotate ballast assembly counter-
clockwise while it is supported by mounting assembly.
After assuring that ballast assembly is properly seated,
screw locking nut onto hanger hub and FIRMLY
TIGHTEN until gasket is compressed against ballast
housing and sealing gland is compressed around support
conduit. Once locking nut is in position it should not be
possible to disconnect or rotate ballast assembly without
loosening nut again.
NOTE: It is recommended that, after final
installation, a thin layer of a silicone sealant
be added all around joint where the conduit
enters sealing gland as a further precaution
against water entering fixture.
LAMP 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.
OPTICAL INSTALLATION
GLASS GLOBE
Attach the globe by threading firmly into the bottom of
the ballast housing.
ACCESSORIES
External Reflector: Thread the reflector firmly onto the
bottom of the ballast housing. Tighten the set screw.
Globe Guard: Insert the protective guard into the ballast
housing and turn clockwise until retained by the detent.
OPTICAL INSTALLATION
REFLECTOR/LENS ASSEMBLY
Thread the reflector/lens assembly onto the bottom of
the ballast housing so that the gasket is compressed.
Tighten the set screw.
To relamp, loosen the set screw and unscrew the
complete optical assembly from the ballast housing.
FUSING
Fuses, if supplied, are located inside the ballast housing.
Access is through the socket cannister assembly opening.
Branch circuit fusing is recommended rather than
individual fusing. Individual fusing may cause unnecessary
maintenance and will not protect the lamp ballast.
MAINTENANCE
It will occasionally be necessary to clean the optical
assembly in order to maintain the light level. Frequency of
cleaning will depend on the dirt level in the user’s facility
and the minimum light level which is acceptable. The
optical assembly 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. Use of abrasive
cleaners will shorten the life of any reflector surface.

Risk of burn
• Allow lamp/fixture to cool before
handling
