Chapter 1 – Safety Instructions
Introduction
Follow all CAUTION notices to prevent damage to the chamber or your test sample. Failure to
follow all CAUTION notices may void your warranty. CAUTION may also indicate a
potentially hazardous situation which, if not avoided, may result in minor or moderate personal
injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
The safety alert symbol ! precedes a general CAUTION or WARNING statement.
The electrical hazard symbol 2 precedes an electric shock hazard CAUTION or WARNING
statement.
Installation Safety Notices
2 WARNING: The power cord is equipped with a NEMA 5-15P grounded/polarized plug. To
prevent a shock hazard, DO NOT defeat the ground or polarization feature.
This device MUST be plugged into a properly grounded and polarized outlet.
! CAUTION: The minimum clearance you should allow for proper ventilation must be at
least 12" from the rear of the chamber.
! CAUTION: This chamber is designed for operation in a conditioned laboratory
environment. Operation above 30°C (85°F) or below 16°C (60°F) ambient
room temperature is NOT recommended.
Operation Safety Notices
! CAUTION: The Temperature Controller’s “Alarm 1” function is NOT used in the
chamber’s safety system and is NOT connected. The independent EZ Zone
Limit Controller functions as the main protection device.
! CAUTION: The Temperature Controller’s “Alarm 2” is configured to lock the
refrigeration control system in “full cooling” mode at temperatures below
–35°C. This alarm setting must NOT be changed under any circumstances!
! CAUTION: Always verify that the EZ Zone Limit Controller settings for high and low
limits are set to temperatures that are appropriate for your test sample.
! WARNING: Do NOT put items in the chamber that could burn or explode at high
temperatures. This chamber uses open wire heating elements which generate
surface temperatures over 1000ºF. This is NOT an explosion-proof chamber.
