5. HANDLING PRECAUTIONS
Warning
1. Hazardous substances
Never process explosive or flammable items. Fire or explosion causing serious injury or
death may result.
See “List of Hazardous Materials” on P.52.
2. Sample moisture precaution
When processing excessively wet samples, remove as much of the moisture as possible
beforehand to prevent condensation from collecting on, and excessive humidity from
having an effect on internal electrical components, possibly causing damage, short circuit
or electric shock.
3. DO NOT operate equipment when abnormalities are detected
If unit begins emitting smoke or abnormal odors for reasons unknown, turn off main circuit
breaker (MCB) immediately, disconnect power cable from power supply, and contact
original dealer of purchase. 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.
Caution
1. DO NOT climb on equipment
Do not attempt to climb onto unit or substitute it for a proper stepladder. 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 operate equipment during thunderstorms
In the event of a thunderstorm, turn off main circuit breaker (MCB), and disconnect power
cable immediately. A direct lightning strike may cause equipment damage fire or electric
shock, resulting in serious injury or death.
3. Caution: HOT
Some exterior surfaces may become HOT during operation. Exercise extreme caution not
to contact these surfaces. Burn injury may result.
Likewise, avoid contact with exhaust ports and surrounding areas, as these may become
extremely HOT.
4. Caution when opening and closing door
Do not attempt to open oven door until chamber has fallen below 50
℃
, or unless unit is
operating below 50
℃
. Interior surfaces will still be HOT at this temperature. Avoid direct
contact with interior surfaces to prevent burn injury.
5. Do not operate unit with door open
Operating DKN-C units with door open will render thermostat unable to maintain proper
temperature control, and may cause damage or premature wear to heater element due
to overloading. Always close door before operation.
Do not leave door open with test samples left inside in attempt to cool samples rapidly.
Hot air dispelling from chamber may cause burn injuries and may damage control panel
or other electronic components.
