Chapter 4 Environmental Requirements
1 Relative Humidity and Temperature
NOTICE
Avoid extremes in temperatures
Optima system room climate requirements – relative humidity and temperature (individual
products or components are classed by their installation area for In use see -Table 4-1)
NOTE: Due to the differential in temperature /humidity between the clinical room and the
room below the floor creates condensation within the Gantry/ Patient table resulting in
part failure or rusting inside the Gantry/ Patient Table, For systems that are planned
for installation on higher grade (second floor or above), the temperature and humidity
of the rooms that are directly below the gantry room should be maintained same as
the exam room requirement. Failure to do so will void the equipment warranty. Avoid
above grade installations where the temperature is high in the area below the gantry/
table cables exit if at all possible.

NOTE: (1): The target temperature (best recommended) is 18°C (64°F).
NOTE: (2a): In use temperature limits specify the range where the system shall work.
Operating outside these limits could occur severe performance and reliability issues.
(2b): Recommended temperature limits specify the range where it is recommended to
adjust air conditioning control in order to warranty current operations inside the in use
range.
Relative Humidity and Temperature: Refer to Table 4-1. To obtain relative humidity and
temperature requirements for components not specified in the table, refer to the appropriate
component Pre–Installation Manual listed in Chapter 2, Basic System Compatibility.
