Humidity
The output device requires relative humidity of 55% ±5%.
An industrial steam humidifier can be used to meet specified humidity.
UV Light
Some plates, such as Kodak DITP, are sensitive to UV light. When such plates are
used or when the Lotem 400 / Lotem 400 Quantum output device is directly
connected to a plate stacker, you need an appropriate safe light.
Air Conditioning
Sufficient air conditioning should be present to provide heat dissipation for the
output device,
plus
all additional equipment residing in the system room, and an
additional minimum 25% safety margin. Ensure that the ventilation system can
circulate the entire volume of air in the room 16 times per hour.
The output device requires a constant temperature of 23

The calculated air conditioning requirements for the output device (in BTU/hour)
are shown in below table.
Please note the following guidelines:
•
The system room should ideally contain both a thermometer and a
hygrometer, permanently mounted in a central location.
•
In addition, it is highly recommended that you have a humidity and
temperature recorder.
Ventilation
No filtration can be 100% efficient (for example, carbon monoxide is not captured
by Creo filters). That is why outdoor air ventilation is required with the debris
removal system. Air exhaust vents (where air is drawn out of the room) should be
located as close to the debris removal cabinet and output device as possible.
The Lotem 400 / Lotem 400 Quantum Family output devices require a minimum
of 1.1 m

outdoor air ventilation. This air ventilation prevents the
accumulation of airborne emissions that may be released when certain media are
imaged.
