Lamp
You may have to install a lamp prior to the initial operation of the fixture. An MSI575 high
intensity discharge lamp is included.
Warning! When replacing the lamp, please wait 15 minutes after powering down to allow the unit to
cool down! Always disconnect from main power prior to lamp replacement.
Do not touch the envelope (glass area) of the bulb with bare hands. If this happens, clean the lamp
with alcohol and wipe it with a lint free cloth before installation.
Lamp Installation
1. Unscrew the 4 screws (S1) to detach the top cover.
2. Unscrew screws (S2) to remove lamp cover and
expose lamp compartment.
3. To remove the lamp, loosen both lamp end
screws (S3) to relieve the pressure from
the lamp socket slots. This way, you will be
able to slide the lamp freely upwards and
out of the lamp socket. Raise the lamp
evenly to remove it.
4. To install a new lamp, loosen both screws
on the double- ended lamp to allow the
lamp to slide into the lamp socket slots.
Lower the lamp evenly.
Warning! Make sure that the clips on the lamp socket
are toward the front of the fixture.
5. Before tightening the lamp end screws,
rotate the bulb until the nipple on the
envelope (N) of the bulb is facing upwards
as illustrated.
