Model 330, 340SC, and 370SC Service Manual
Avoid Projector Angles of 15° to 23°
Due to voids in the prism fluid there is a dead zone of 19° ± 4°. For this reason, avoid
projector angles of 15° to 23°.
Maximum Projector to Screen Angle is 15°
The maximum vertical tilt angle from projector to screen is 15°. This is the maximum
amount of keystone correction that is possible.
Heat Safeguards
Fans
The projector has multiple fans (exact number varies with projector model number) to
cool the projector system. Do not block the intake or outflow of any of the fans.
Intense heat is emitted within the system and must be properly dissipated in order to keep
the system running properly.
CAUTION!
Do Not Block Ventilation. Blocking air intake or exhaust
ports can lead to projector overheating. Do not enclose the unit in a restricted
space. Refer to the appropriate
Operator’s Manual
for physical access and
thermal clearance and for specific clearances needed for heat dissipation. Allow
at least ten (10) minutes for projector cool down before removing power.
CAUTION!
Do not unplug the power cord until after the arc lamp fan
has stopped running. This fan protects the arc lamp from overheating.
Light Safeguards
Ultra Violet and Infrared Light
Eye/face protection is required from ultra violet light and infrared light in accordance
with the following conditions:
1.
X3 (up to 375 nanometers) shade goggles must be worn by anyone near the
projector when the lamp is lit and the cover is off.
2.
X5 (375 to 700 nanometers) shade goggles when actually working on the
projector near the arc lamp source.
