To reduce the risk of the lamp shattering it is strongly recommended that the lamp is replaced when
the rated average life has been exceeded by 25%. Since the rated average life for both the MSR
1200 and HHI 1200 lamp is 750 hours, they should be replaced before 900 to 950 hours of use. The
procedure for installing the lamp is described in section 2 - 'INSTALLING THE PRO 1220'.
The position of the lamp-holder may need to be re-adjusted to ensure optimum performance when
the Pro 1220 is installed in its permanent site. Though the Pro 1220 has some built-in sequences for
adjustment purposes (appendix b), it is suggested that you use a controller so you can focus the
beam on the required distance. The adjustment procedure is as follows:
W A R N I N G !
Whilst adjusting the position of the lamp you will be exposed to extreme heat
and intense light. A minor risk of lamp explosion is also present and therefore
caution should be taken by covering skin and by wearing eye and face protec-
tion. Since the cooling of the lamp is reduced during this adjustment, you
should minimize the time used.
Before you start adjusting the lamp, you will have to remove the main-cover from the fixture as
described in section 2 - 'INSTALLING THE ROBOSCAN PRO 1220'. Once you have removed the
cover, you will see a black access cut-out switch positioned on the dimmer module. This switch
serves to cut out the lamp if, for any reason, the main-cover is removed. Before powering on the
fixture, and whilst adjusting the lamp position, this switch needs to be held down continuously.
