Projector Installation Notice
There is no limitation angle for projector installation.
Allow at least 50 cm clearance around the exhaust vent.
Ensure that the intake vents do not recycle hot air from the exhaust vent.
When operating the projector in an enclosed space, ensure that the surrounding air temperature
within the enclosure does not exceed operation temperature while the projector is running, and the
air intake and exhaust vents are unobstructed.
All enclosures should pass a certified thermal evaluation to ensure that the projector does not
recycle exhaust air, as this may cause the device to shutdown even if the enclosure temperature is
with the acceptable operation temperature range.

Verify Installation Location
To supply power, the 3-blade (with earthing lead) socket should be used to ensure proper
grounding and equalized ground potential for all of the equipment in the Projector System.
The power code provided with the Projector should be used. In case of any missing item, other
qualified 3-blade (with earthing lead) power cord can be used as substitution; however, do not use
2-blade power cord.
Verify if the voltage is stable, grounded properly and there is no electricity leakage.
Measure total power consumption which should not higher the safety capacity and avoid safety
issue and short circuit.
Turn on Altitude Mode when located in high altitude areas
The projector can only be installed upright or inverted.
When installation the bracket, make sure the weight limit is not exceed and firmly secured.
Avoid installing near air conditioner duct or subwoofer.
Avoid installing at high temperature, insufficient cooling and heavy dust locations.
Keep your product away from fluorescent lamps (>1 Meter) to avoid malfunction
caused by IR interference
The VGA IN connector should be connected to the VGA IN port. Note that it should be inserted
tightly, with the screws on both sides securely fastened to ensure proper connection of the signal
wire for achieving optimal display effect.
The AUDIO IN connector should be connected to the AUDIO IN port and CANNOT be connected
to AUDIO OUT or other ports like BNC, RCA; otherwise, it will lead to mute output and even
DAMAGE the port.
Install the projector above 200cm to avoid damage.
The power cord and signal cable should be connected before power on the projector. During the
projector starting and operating process, DO NOT insert or remove the signal cable or the power
cord to avoid damaging the projector.
Cooling notes
Air outlet
Make sure the air outlet is 50cm clear of any obstruction to ensure proper cooling.
Air outlet location should not be in front of the lens of other projector to avoid causing illusions.
Keep the outlet at least 100cm away from the inlets of other projectors
The projector generates a massive amount of heat during use. The internal fan dissipates the heat
of the projector when shutting down, and such process may continue for a certain period. After the
project enters STANDBY MODE status, press the AC power button to turn off the projector and
remove the power cord. DO NOT remove the power cord during the shutdown process, as it may
cause damage to the projector. In the meantime, the delayed heat radiating will also affect the
service life of the projector. The shutdown process may vary depending on the model used.
Whatever the case may be, be sure to disconnect the power cord till after the projector enters the
STANDBY status.
Air inlet
Make sure there is no object blocking air input within 30 cm.
Keep the inlet away from other heat sources
Avoided heavy dust area

Power Safety
Only use the supplied power cord.
Do not place anything on the power cord. Place the power cord where it will not be in the way of
foot traffic.
Remove the batteries from the remote control when storing or not in use for a prolonged period.
Cleaning the Projector
Unplug the power cord before cleaning. See Cleaning the Projector page 60.
Allow the light source to cool for about one hour.
Regulatory Warnings
Before installing and using the projector, read the regulatory notices in the Regulatory Compliance on
page 79.
Symbol Explanations
DISPOSAL: Do not use household or municipal waste collection services for
disposal of electrical and electronic equipment. EU countries require the use
of separate recycling collection services.
Special Care for Laser Beams!
Special care should be considered when DLP projectors and high power laser equipment are used in the
same room as.
Direct or indirect hit of a laser beam on to the projector lens can severely damage the Digital Mirror
Devices (DMD™).
Sun light Warning
Avoid using in direct sun light.
Sun light on the projector lens can severely damage the Digital Mirror Devices (DMD™).

Note:
When installing, ensure that you use only UL Listed ceiling mounts.
For ceiling installations, use approved mounting hardware and M6 screws with a maximum screw
depth of 12mm (0.47 inch).
The construction of the ceiling mount must be of a suitable shape and strength. The ceiling mount
load capacity must exceed the weight of the installed equipment, and as an additional precaution
be capable of withstanding three times the weight of the equipment over a period of 60 seconds.

Reference drawings for stand
Please hire an installation service provider (for a fee) for the design and manufacture of a customized
stand to be used for portrait projection. Please ensure that the design complies with the following
conditions:
•Use the 6 screw holes at the back of the projector to secure it to the stand.
Screw hole center dimension: 300 × 350 (pitch = 175) mm
Screw hole dimension on the projector: M6 with the maximum depth 12 mm
•Horizontal adjustment mechanism (for example, bolts and nuts in 4 places)
•Please design the stand so that it does not easily topple over.
The drawing showing the dimensional requirements is not an actual stand design drawing.
