GENERAL SAFETY PRECAUTIONS
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.
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.
DO NOT touch refrigeration piping during chamber operation. The refrigeration piping
can become very hot or extremely cold, and cause severe burns.
High voltage remains present during an alarm. This unit must be locked out at the main
power source prior to servicing. The enclosure cover should also remain installed at all
times.
Lock-out main power prior to servicing. High voltage remains present on main electrical
panel with covers removed.
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! ow from blowing particles or
objects into your eyes.
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.
The refrigeration unit is a pressurized system and hazards exist which could result in
personal injury. Removal and installation of the hermetic compressor be performed by
experienced personnel only. Failure to follow these instructions may result in serious
personal injury.
Gaseous nitrogen/C02 vent connection must be ducted to the outdoors to prevent
displacement of oxygen around the unit.
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/538°C. This is NOT an explosion-proof chamber.
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.
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.
DO NOT reach into an enclosure to service or adjust equipment except in the presence
of someone who is capable of rendering aid.
