TestEquity 1007S Temperature Chamber
Operation Safety Notices
!
CAUTION:
This chamber has a crankcase heater to protect the 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 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:
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.
!
WARNING:
The chamber door must remain closed while the chamber is operating. If you
need to open the door while the chamber is operating, wear safety goggles to
prevent the high velocity airflow from blowing particles or objects into your
eyes.
!
WARNING:
This chamber operates at extreme temperatures. Avoid contact with air,
objects, and surfaces that are hot or cold to prevent severe burns or frostbite.
Protective gloves are recommended.
