DO NOT replace components or make adjustments inside the equipment with the main
power supply turned on. Under certain conditions, dangerous potentials may still exist
when the power switch is in the off position due to charges retained by capacitors. To
avoid injury, always remove power and ground a circuit before touching it.
WARNING
!
Paint thinners, cleaning solutions and other chemicals or solvents should never be stored
in the vicinity of the unit. High operating temperatures and live electrical circuits could
ignite fumes and cause an explosion.
WARNING
!
Do NOT climb or place top heavy objects on the top of the chamber.
WARNING
!
DO NOT reach into an enclosure to service or adjust equipment except in the presence of
someone who is capable of rendering aid.
WARNING
!
All OSHA and other applicable local and national codes, regulations, and guidelines
regarding lockout/tagout procedures must be followed while servicing this unit. This may
include a lockable disconnect switch to remove power from the equipment while servicing.
WARNING
!
PRODUCT PROTECTION. Chambers are equipped with high heat limits or safety
devices. These safety devices are installed to protect the chamber from exceeding design
limits. These safety devices remove power ONLY from the chamber heaters and
DO NOT
remove power from your product. Provisions must be made to de-energize the product on
test and the chamber in the event of an over-temperature protection.
WARNING
!
DO NOT place 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 (537°C). This is
NOT an explosion-proof chamber.
WARNING
!
Gaseous nitrogen/CO2 vent connection must be ducted to the outdoors to prevent
displacement of oxygen around the unit.
WARNING
!
The refrigeration unit is a pressurized system and hazards exist which could result in
personal injury. It is therefore recommended that removal and installation of the hermetic
compressor be performed by experienced personnel only. Failure to follow these
instructions may result in serious personal injury.
WARNING
!
This chamber operates at extreme temperatures. Avoid any personal contact with objects
and surfaces that may be hot or cold to prevent severe burns or frostbite.
WARNING
!
The chamber door must remain closed during operation. If the door is required to be open,
wear safety goggles to prevent the high velocity air
fl ow from blowing particles or objects
into your eyes.
WARNING
!
Lock-out main power prior to securing. High voltage remains present on main electrical
panel with covers removed.
WARNING
!
DO NOT touch refrigeration piping during chamber operation. The refrigeration piping can
become very hot or extremely cold, and cause severe burns.
