• Changing the lamp
Open the projector, loosen the two
side nuts (20) of the lamp to be
changed and remove it from the sup-
ports (
21). Remove the new lamp from
its box, loosen the two side nuts (20)
and locate the lamp in the supports
(
21). Finally, retighten the nuts.
• Changing the colour filters
Having opened the projector,
identify the filter to be
changed, grip firmly between
thumb and forefinger and push
against the spring clip (23)
until free of the fixed clips (24).
Bend the filter outwards and
remove.
Offer the new filter to the
spring clip (23) and anchor
behind the two fixed clips (24).
IMPORTANT: for uniform distribution of
the light beam, the lamp must be posi-
tioned so that the glass pip (
22) on the
bulb does not coincide with the optical
axis of the projector. With this in mind,
locate the pip as high up as possible.
CAUTION: The projector uses a high pressure lamp with external starter.
- When fitting a new lamp, read the manufacturer's instructions carefully.
- The lamp must always be changed without delay if damaged or deformed by
heat.

• Installing wide angle lenses
Remove the projector front
cover. Unscrew knobs (25),
rotate the front lens plate (26)
from the parking position to
the operating position in
alignment with the projector
axis and then perform the
same operation with the rear
lens plate (27).
Refit the knobs and secure
the two lens plates.
• Lubrication of sliding contact
parts - QS LT
To ensure perfect operation of sliding con-
tact parts of the projector, lubricate spar-
ingly at 6-monthly intervals using Kernite
Lube-K-AC grease.

MAINTENANCE
IMPORTANT: isolate the projector from the electrical power supply before com-
mencing maintenance work of any description.
The maximum temperature on the outer surface of the projector under normal
operating conditions is 90°C (194° F) for QS and Basic HMI 1200 versions, and
80°C (176° F) for the Basic HMI 575 version.
After switching off, do not remove any part of the projector for at least 10 minutes, as
indicated on the lamp change label (1).
Once this time has elapsed, the risk of a lamp exploding is practically zero. If the lamp
needs changing, wait a further 20 minutes to avoid the risk of burns. In the event of a
lamp exploding, the projector is designed to prevent fragments of glass from being
scattered. The lenses supplied with the projector must be fitted at all times, and if vis-
ibly damaged must be replaced promptly with genuine spares.
• Opening the projector
Loosen knob (16) to remove the lamp access cover (17) or loosen knob (18) to
remove the front cover (19). Once the necessary work has been completed, refit the
cover and tighten with the relative knob.
