5. HANDLING PRECAUTIONS
Caution
1. DO NOT climb on equipment.
Do not attempt to climb onto unit or substitute it for a proper step ladder. Units are not designed
to support bodily weight and damage may result. In addition, unit may become unstable and tip
over or fall resulting in equipment damage, serious injury or death.
2. DO NOT place items on equipment.
Do not place any objects on unit. Doing so may cause unit to become unstable and tip over,
resulting in possible equipment damage, injury or death.
3. DO NOT operate equipment during thunderstorms.
In the event of a thunderstorm, turn off main power switch (ELB), and disconnect power cable
immediately. A direct lightning strike may cause equipment damage fire or electric shock,
resulting in serious injury or death.
4. DO NOT leave chamber door open.
Do not leave DF/DH unit door open (i.e. to cool test samples while in chamber, etc.) following an
operation run. Heat from chamber may damage and/or deform control panel, causing control
board malfunction or failure. Always remove processed test samples and close chamber door.
5. DO NOT process corrosive items.
Do not process items containing corrosive chemicals of any kind. Despite stainless steel
chamber structure, damage may nonetheless occur from exposure to strong chemicals.
6. ALWAYS run equipment within specified temperature range.
Working temperature range is room temperature +15°C
~
260°C (DF412/612) and +15°C
~
360°C (DH412/612).
Never attempt to operate unit outside of specification range. Equipment malfunction or damage
may result.
7. Arrange test samples appropriately.
Weight capacity for one chamber rack is approximately 30kg. Test sample load total for each
rack should not exceed this specification.
Arrange test samples evenly on racks, leaving as much space between them as possible.
Do not place too many test samples on rack at once. Doing so may hinder proper temperature
control in chamber. Test samples should be managed in the following way; 1. Install the
supplied chamber racks, 2. Leave as much space between test samples as possible, 3. As a
general rule, leave 30% or more of the total space on each rack unoccupied
Leave 30% of total rack space open.
