5. HANDLING PRECAUTIONS
Warning
1. DO NOT process hazardous or harmful substances.
Never process explosive or flammable items. Fire or explosion causing serious injury or death
may result. See “List of Hazardous Substances” (P.64) for more information on these items.
2. Use extreme caution when heating in resin containers.
Confirm temperature tolerance before using resin containers or vessels. Heating resin beyond
capacity to withstand temperature will cause resin to melt and may result in a fire or explosion.
3. DO NOT operate equipment when abnormalities are detected.
If unit begins emitting smoke or abnormal odors for reasons unknown, turn off main power
(ELB) immediately, disconnect power cable from power supply, and contact a local dealer or
Yamato sales office for assistance. Continuing to operate without addressing abnormalities may
cause fire or electric shock, resulting in serious injury or death. Never attempt to disassemble or
repair unit. Repairs should be always be performed by a certified technician.
4. DO NOT insert foreign objects into unit openings.
Never insert metal or combustible objects into unit openings, ventilation ports or exhaust ports.
Fire or electric shock, causing serious burns, injury or death may result.
In the event that a foreign object accidentally falls inside, turn off main power (ELB)
immediately, disconnect power cable and contact a local dealer, or Yamato sales office for
assistance. Continuing to operate unit without removing object may cause fire or electric shock
resulting in serious injury or death.
5. Use extreme caution in handling samples following high temperature operation.
Sample/process items are HOT! Do not touch upon removal from chamber, following high
temperature operation. Use heat-resistant gloves and exercise extreme care in order to avoid
getting burned.
6. Use extreme caution when opening unit door during high temperature operation.
When necessity dictates opening door during high temperature operations, maintain a safe
distance until hot air, expelled from chamber, has dissipated. DO NOT touch internal door or
other heated interior surfaces. Severe burns may result.
Likewise, DO NOT touch exterior door surface, cable ports, exhaust port or any other surface
areas which are likely to become hot during operation. Burns may result.
Be advised that if a fire/smoke alarm is installed in close proximity to unit, it may be set off when
chamber door is opened and hot air or smoke is expelled.
7. DO NOT touch hot surfaces.
Never touch the door, cable or areas surrounding exhaust port during or immediately following
an operation. Severe burns may result.
8. Clean level.
Clean level, class 100 (FED-STD-209D) is maintained when chamber temperature inside is
stable, but not guaranteed while temperature is increasing or decreasing.
Optional high-performance products are available to maintain clean level class 100 during
temperature changes in the chamber. See the List of options on P.61.
