with air conditioning during warm months and warmed during cold months usually
maintain an acceptable level of humidity. However, if the site is unusually
humid, use a dehumidifier to maintain the required humidity level.
(low-pressure) conditions outside of 0 to 10,000 feet (0 to 3050 m) can reduce
the cooling efficiency and cause electrical problems.
To prevent contaminant buildup and increased internal chassis
temperatures, make sure that the operating environment is as clean as possible
and free of dust and other contaminants. Do not permit smoking, food, or drinks
