Gotham CTH8 (T6) HID CYLINDERS - Manuel (Page 4)

MOUNTING CYLINDER FOR STEM MOUNT:
1. Install stems per instructions provided with stem
assembly.
2. Ensure length of wire used will be long enough to
leave at least 10” out of bottom of stem and is rated
for 150°C.
3. Thread top cap onto stem ensuring a tight,
secure fit.
4. Hook cylinder body to top cap using safety chain,
make wire connections and reinstall cylinder to top
cap ensuring all bolts are in place and tightly
secured (see Figure 4).
MOUNTING CYLINDER FOR SURFACE MOUNT:
1. Attach top cap SECURELY to ceiling in 3 places
over 4” square or octagonal junction box (hardware
supplied by others) . DO NOT ATTACH TO J-BOX
WITHOUT SECURING TOP CAP TO CEILING IN 3
PLACES PROVIDED.
2. Hook cylinder body to top cap using safety chain,
make wire connections and reinstall cylinder to top
cap ensuring all bolts are in place and tightly
secured (see Figure 4).
MOUNTING CYLINDER FOR WALL MOUNT:
1. Loosen set screw in bottom of wall cover plate
and remove mounting plate (see Figure 5b).
2. Pull supply leads through hole in mounting plate
aligning correct hole patterns between mounting
plate and junction box. Secure plate to junction box
(see Figure 5a).
3. Hook cylinder body to mounting plate using
safety chain. Make all wire connections and stuff
wire/connectors into junction box.
4. Attach cylinder by hooking wall cover plate over
top section of mounting plate (see Figure 5b).
5. Secure cylinder to mounting plate by tightening
set screw in bottom of wall cover plate.
6. After mounting fixture to wall, place a bead of
silicone based caulking compound along where the
wall cover plate meets the wall on the top and on
each side (see Figure 5c). DO NOT CAULK
ALONG THE BOTTOM.
SERVICING:
For servicing ballasts on all types
1. Turn power off.
2. Gain access to lamp for removal (ED17 and
PAR lamps only)
3. Refer to “Preparing Product for

SAVE THESE INSTRUCTIONS
Symptom Possible Cause Corrective Action
LAMP FAILS TO
LIGHT •Circuit feeding the fixture not
energized.
•Wiring error in circuit or module
connection.
•Faulty lamp.
•Line or ballast output.
•Faulty ballast.
•Ambient temperature too low.
•Check circuit breaker or fuse to ensure that circuit is
energized.
•Examine fixture splice box to ensure that connections are
correct.
•Remove the faulty lamp and substitute another lamp.
Preferably one that is known to light. If lamp lights, replace
the original with a new one.
•Check line voltage at fixture. Check open circuit voltage.
•Check circuit continuity.
•Check ballast rating against existing environmental
conditions.
LAMP GOES OUT
AFTER LIGHTING •Faulty lamp •Occasionally a lamp will exhibit this symptom rather than
simply failing to light. Substitute a new lamp.
LAMP CYCLES
ON AND OFF •Insulation too close to fixture.
•Lamp wattage too high.
•Ballast output voltage low. •Remove installation from around module (at least 3”).
•Install lamp wattage specified in housing.
•Check line voltage at the fixture. Check open circuit voltage.
TROUBLESHOOTING CHART
Check for any visible damage to the lamp or frame-in module. If they seem in good condition, locate the problem
