TestEquity 1016C-1027C Temperature Chamber
Operation Safety Notices
!
CAUTION:
This chamber has a crankcase heater to protect the high-stage compressor. The
chamber must be connected to the power source AND the Main Disconnect
Switch must be ON for 3 hours prior to operating the chamber. Although it
may be safe to use the chamber immediately, this procedure ensures the
longest possible life for the high-stage compressor if the chamber has been
removed from the power source for more than 24 hours.
!
CAUTION:
The Temperature Controller’s “Alarm” functions are NOT used in the
chamber’s safety system and are NOT connected. TestEquity does NOT
recommend using the Temperature Controller’s alarm function as the main
protection device. The independent EZ-Zone Limit Controller functions as the
main protection device.
!
CAUTION:
The EZ-Zone Limit Controller has been properly configured by TestEquity to
match the chamber’s system requirements. Improper modifications to these
setup values can result in unreliable and unsafe operation. Do not attempt to
modify the setup values, unless you thoroughly understand what you are
doing. The correct values are documented in the “EZ-Zone Limit Controller
Setup Parameters” section of this manual.
!
CAUTION:
Always verify that the Limit Controller’s high and low limits are set to
temperatures that are appropriate for your test sample.
!
CAUTION:
If your test sample is energized, it may be capable of raising the workspace
temperature beyond safe limits. This could occur if your test sample exceeds
the live load rating of the chamber or if the chamber’s refrigeration system
fails. This chamber has a set of contacts that can be used to remove power to
your test sample if the Limit Controller’s temperature limits are exceeded.
!
CAUTION:
To prevent damage to your test sample and the chamber’s compressors, do not
exceed the live load rating of the chamber.
!
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.
!
WARNING:
Do NOT put items in the chamber which can emit corrosive vapors or
substances.
!
WARNING:
This chamber is NOT a curing oven. There are NO provisions for venting
fumes.
