Projection relationships (continued)
If you are installing the projector in a sealed space, be sure to provide additional air conditioning
equipment and ventilation equipment. Insufficient ventilation will result in an accumulation of
heat and may activate the projector's protection circuit.
z
Avoid setting up in places which are subject to sudden temperature changes, such as near
an air conditioner or lighting equipment (studio lamps, etc.).

Dimensional relationship
For details on the projection distance (L), refer to “Projected image size and Projection
distance” and “Projection distance formulas” in the Appendix.
Note

For details on “Projected image size and Projection distance” for projector models other
than PT-MZ20K / PT-MZ17K / PT-MZ14K / PT-MZ11K / PT-MZ16K / PT-MZ13K / PT-
MZ10K, refer to “Setting up” in the operating instructions of the projector.
Perform the lens position shift within the adjustment range.
Perform lens shift adjustment within the ranges shown in the following illustrations.
The focus may change when the lens position is shifted out of the adjustment range.
This is because the movement of the lens is restricted to protect the optical parts.
Projection position can be adjusted with the optical axis shift based on the home position
in the respective range.
