Notes on the installation (DLA-G20/DLA-S15)
Inclination of the projector
Do not install the projector inclined to the left and right. Otherwise, color unevenness may occur or the lamp life may be shortened.

Space required for heat radiation and
maintenance
To maintain stable performance of the DLA-G20/DLA-S15 for a
long period, it is necessary to provide sufficient space for heat
radiation and maintenance before installation. Otherwise,
overheating may result in deteriorating performance or damage to
the projector.
The minimum space required is shown above.
Fixing the projector to the
metal fittings
Lamps should be replaced regularly based on usage time. If the
projector is fixed to metal fittings, leave enough space (as shown
on the left) for lamp replacement. The ceiling hanging metal
fittings "EF-G10CJ" and data box "DB-70S10" allow the projector
to be moved with the hinge for lamp replacement.
Notes on ambient temperature
• The DLA-G20/DLA-S15 uses a high output lamp to obtain high intensity light. Therefore, it generates a lot of heat (540 kcal/h). Be sure
to install the projector in a well ventilated location or provide some form of air conditioning.
• To enhance the cooling effect and ensure reliable performance, ensure that there is sufficient peripheral space and install an
air-conditioner. Ideally a fixed temperature should be maintained.
• Sudden changes in temperature can cause condensation. If the projector is moved from a cold place to a warm place or the room
temperature rises suddenly, wait at least one hour before turning the power on. Also, ensure that humidity levels are kept low.
• Do not block the ventilation slots or wrap the operating projector with a cloth, etc. Do not install the projector close to other equipment as
this can interfere with air flow and result in rising internal temperature.
Air intake and exhaust of the
DLA-G20/DLA-S15
The DLA-G20/DLA-S15 uses air to cool itself (as shown in the
figure below). Therefore, do not block the intake and exhaust
ports or place an object near the ports. Since air intake is
performed at the base and only minimum clearance is kept when
the projector is installed, be careful not to reduce the clearance by
inserting paper or other objects beneath the unit.

The projector can
be set upside down
and hung from the
ceiling.
(It is recommended
to use the dedicated
hanging metal fittings "EF-G10CJ".) If the projector
is set upside down, the intake port faces upward
so be careful of dust.

Ceiling suspension
The DLA-G20 can be set upside down and suspended from a
ceiling. Make sure there is enough space for the intake and
exhaust ports to dissipate heat and to allow easy maintenance
access (attach an elevator to move the projector up and down
easily for maintenance and leave enough space for lamp
replacement).
For installation of special metal fittings, it is necessary to
use the feet of the projector or make an opening for intake port or
lamp replacement. Use the dedicated "EF-G10CJ" ceiling
hanging metal fittings.

• The lens of the DLA-G20 is not located at the center. When attaching the metal fittings,
the lens center is shifted from the center of the pedestal metal fittings by 79 mm. Take this
into consideration when determining the installation position.

• To lower the screen further, put a cushion
for adjustment between the metal fittings and
the ceiling and lower the projector as well.
• To raise the screen further, a cavity must be created in the
ceiling for the projector installation. If this is not possible,
trapezoid distortion may occur. Screen
Permanent installation on a table or
shelf
To prevent the projector from falling, tipping over, etc., you may
want to fix it securely to the platform, table or shelf where it is
installed. You can do this with the "EF-G10CJ" ceiling hanging
metal fittings. The table should also be firmly anchored to the
floor.
• In all installations, the supporting platform (ceiling, table, etc.)
must be able to support a total weight of at least 20.5 kg (14 kg
projector and 6.5 kg "EF-G10CJ" ceiling hanging metal fittings).
The weight of these items could result in a serious or fatal injury if
an accident were to occur. Special precautions should be taken
to prevent the projector from falling or being knocked over even
under severe conditions such as an earthquake.
*For details, refer to the
"EF-G10CJ" instruction manual.
