(7) Heat value calculation
In the calculation, assume that the maximum power consumption per multi-projection unit is 300 W by re-
serving a certain headroom. As most of the consumed power becomes heat, the power consumption can be
regarded to be proportional with the calorific value.
1 Conversion into calorific value (kcal/h)
[W] x 0.86 = [kcal/h]
Calorific value per multi-projection unit
300 x 0.86 = 258 (kcal/h)
2 Conversion into British thermal unit
[W] x 3.41 = [B.t.u./h]
Calorific value per multi-projection unit
300 x 3.41 = 1023 (B.t.u./h)
Projection units Calorie (kcal/h) British (B.t.u./h)
1 screen 258 1023
4 screens 1032 4092
9 screens 2322 9207
(8) Temperature and humidity conditions
Closely observe the following conditions on the temperature and humidity of the location of installation.
(1)Operating temperature : 5 to 35 degC (No condensation)
(2)Operating humidity : 20 % to 80 %
(3)Storing temperature : –10 to 45 degC
The lenticular sheet will stretch and consequently the center of the screen will rise if the humidity is relatively
high. In this case, the focus may slightly change and therefore readjustments in the installing conditions of
the location must be performed when your system arrives.
Avoid wetting the system at all times. Due to the shape of the product, it is easily affected by external condi-
tions. Especially to be avoided is wetting the MPJ and screen. Thorough water-proof measures must be taken
when installing them in locations where there is a high level of moisture in the air such as near air-condition-
ing vents and water sprays.
* Take note that in new buildings, moisture is frequently produced from the concrete and the humidity level
subsequently rises.
Electrical equipment such as this system should not be installed in high humidity environments. Follow the
precautions below when high humidity is expected.
Never install the MPJ and screen in locations that do not meet their respective specifications.
Ground the units.
Ensure that there is no condensation.
Install the units where no one can touch them.
Ensure that water droplets do not fall onto the units.
(9) Condensation
One problem that occurs in the winter season is “Condensation”. When the temperature of the room in which
this system is installed rises suddenly, condensation occurs on the screen and lens, thereby the system cannot
display its best performance. In such cases, turn off the power once, leave the system off for one hour, and turn
on the power again. Increasing the room temperature gradually is another method.
