LAMP LOOSE
IN SOCKETS
Make sure that the lamp is fully inserted into the sockets and that the
sockets are in the closed position.
INCORRECT
VOLTAGE
Make sure you are using the correct input voltage with ballast. If using
incorrect voltage, disconnect the ballast from the power source immediately.
DEFECTIVE
OR IMPROPER
WIRING
Examine wiring to ensure it agrees with wiring diagrams on ballast label.
Check connections to see that they are secure. If wiring a 240V ballast,
DO NOT use a neutral. The correct wiring is two hot wires and a ground.
POOR ELECTRICAL
CONNECTIONS
Check wiring and lamp contact with socket. Make sure the lamp cord is
firmly seated in output receptacle.
INCORRECT
LAMP
Verify that you are using a 1000W double ended lamp. Lamps manufactured
according to European or Asian specifications will not provide consistent
performance.
LAMP
DAMAGE
Investigate possibility of outer bulb damage.
Look for broken tubes or loose metal parts. Replace lamp.
