[5] INSTALLATION

A. Installing conditions

To ensure safety and proper machine performance, please note the
following before initial installation and whenever the machine is to be
relocated.

1. The copier should be installed near an accessible power outlet for
easy connection.

2. Be sure to connect the power cord only to a power outlet that
meets the specified voltage and current requirements.
Also make certain the outlet is properly grounded.

3. Do not install the machine where it is:

• damp or humid,

• exposed to direct sunlight,

5. Be sure to allow the required space around the machine for ser­vicing and proper ventilation.

11-13/16"
(30cm)

12/8"
(60cm)

12/8"
(60cm)

A small amount of ozone is produced within the copier during
operation.
The emission level is insufficient to cause any health hazard.

NOTE:

The present recommended long term exposure limit for ozone is

0.1 ppm (0.2 mg/m3) calculated as an 8 hr. time-weighted average
concentration.
However, since the small amount that is emitted may have an
objectionable odor, it is advisable to place the copier in a
ventilated area.

00-13/16"
(30cm)

• extremely dusty,

• poorly ventilated,

• subject to extreme temperature or humidity changes (e.g., near

an air conditioner or heater).

4. Ensure that the area chosen for the machine location is level.
