when the temperature in the chamber drops below the lower limit of the wait width deviation temperature due to, for example, opening of the door until the temperature in the chamber will recover above that lower limit. At [OFF] the process will proceed to the next step after the set time irrespective of changes of the temperature in the chamber.

※ When you use the repeat function, program the operation so that the set temperature before shifting

to the repeat mode will be the same as the set temperature of the destination of repetition.

※ Checking the heating capacity and the cooling capacity before setting is encouraged since these

When the wait function is set to [ON], the mode will remain “waiting” without counting down the time until temperature in the chamber (indication) will be within the wait deviation range between -3℃ and +6℃

to the set temperature. When you set the set time to 0 minute, the unit will operate from the “Start

temperature” to the “Set temperature” at full power.

When you have set time longer than the specified performance, the unit will control heating and cooling so that the set temperature will be attained (within the wait width deviation range) at the set time. Even when the indicated temperature drops while temperature is stable due to opening of the door, the mode will remain “waiting” without counting down the time if the wait width upper or lower limit is exceeded.

When you set the wait function to [OFF], the unit will proceed to the next step at the set time irrespective whether the temperature is within the wait width deviation between the set temperature and the

indicated temperature. When the set time is set to a short time exceeding the heating and cooling capacity, the unit will proceed to the next step before the set temperature is attained and you need to make sure that the wait function

is set at [ON] when you are going to operate at the full power.

If a foreign object has entered inside, immediately turn the ELB off and ask your dealer, one of our sales offices or the customer service center for inspection. Leaving as it is will cause a fire or an electric shock.

Take care not to touch samples when taking them in or out since inside the chamber, internal wall of the door or samples are still hot for some time after operation at a higher temperature. Be sure to put on heat-resistance gloves and take extreme care for burning when handling samples.

When you attempt to open the door during operation at a higher temperature, never touch the door since the internal chamber or the inside of the door are hot. When the door is opened, the heater and the fan motor will stop for safety but note that the fan motor will keep rotating from inertial and hot air will be blown out.

Note that if a fire alarm is installed around the unit, it may go off erroneously.

Never touch the door, the cable port or around the exhaust port during or immediately after operation. They are hot and may cause burning.

5. Handling precautions

1. Never use any explosive or flammable substances.

2. Take extreme care when using a resin container.

3. Turn the ELB off when an abnormality occurs.

Warning

4. Do not put any foreign objects in the unit.

5. Take extreme care for handling of samples after operation at a higher temperature.

6. Take extreme care when opening the door during operation at a higher temperature.

2. Do not place any stuff on the Equipment

3. Turn immediately off the Breaker of the Equipment at thundering.

4. Do not keep Door open after operation.

Caution

5. Do not process any corrosive samples.

6. Operate at the proper temperature.

7. Take extreme care when placing samples.

Page 52

Never set samples on bottom of Chamber. If samples will be processed at setting on bottom of it, this Equipment may be not given as its full performance and become high temperature unlikely and also cause failure. Set samples on attached shelves properly installed on their brackets.

Do not allow samples to contact directly to side walls of Chamber.

Do not process humid specimens. Water condensed inside the unit may cause an electric shock, a malfunction of the unit or deterioration of HEPA filter.

Do not attempt to process wet samples.

The unit employs blowing to improve temperature distribution inside the chamber. When processing powder or small samples, make sure that the sample will not scatter. A fire or an electric shock may result if a flammable or a metal object enters the heater. When processing smaller specimens, you can minimize circulating wind amount in the bath by setting the variable wind speed to low, in which case the temperature performance will be out of the warranty and the user needs to confirm the temperature characteristics.

Heating may take some time when the amount of samples is large or when processing samples with a larger heat burden. Check the appropriate amount as necessary and set the sample. Also note that the temperature indication may be unstable when processing heat-generating samples (note that sample itself must be free of fear of explosion, inflammation or ignition).

Be aware of temperature sensor which it is installed on Chamber inside right portion and control Chamber temperature. Therefore, if the amount of specimen is large or the equipment is in the middle of heating, sensor detected temperature may not agree with temperature of the samples. In particular, actual Chamber temperature will differ greatly from Read Temperature displayed on Controller, right after opening or closing of this Equipment Door. When a gap occurs between the temperature in the bath and the measured temperature requiring adjustment, compensate temperature by referring to “P.39 Setting a calibration offset”.

When operation stopped from a power failure and then power recovers, the unit will automatically resume operation. See “P.40 Setting the recovery mode” for details.

Must be set temperature of Independent Overheat Prevention Device (IOPD). Note that temperature of this IOPD must be set to temperature over 20℃ higher than Target

Temperature. Refer to Chapter 4. Operating Procedure –“Independent Overheat Prevention Device” for how to set and other cautions on page 46.

5. Handling precautions

8.Never set samples on bottom of Chamber.

9. Do not process humid or wet specimens.

10. Take care for processing of powder and small samples.

Caution

11. Note that the sample temperature and the measured temperature are not always the same.

12. Check the following in terms of the recovery mode.

13. Be sure to set a temperature of the Independent Overheat Prevention Device.
