8. Choose a correct socket
Choose a correct power socket that meets the unit’s rated electric capacity.
Electric capacity DP83C AC220V 18.5A (not contain vacuum pump current)
DP104C 3-phase 480V 17.5A (not contain vacuum pump current)
There could be the case that the unit does not run even after turning ON the power. Inspect
whether the voltage of the main power is lowered than the specified value, or whether other
device(s) uses the same power line of this unit. If the phenomena might be found, change the
power line of this unit to the other power line. This unit does not have plug, please consult
your dealer or a local electrical contractor for power connection.
9. Installation and layout
It may cause injure to a person if this unit falls down or moves due to earthquake or impact.
To prevent, take measures that the unit cannot fall down, and not install at a busy place.
The unit is equipped with casters, check if the casters are locked.
Hang the caster handle, in front of the caster, over its tyre from side.
10. First use
When first using the unit, it may stink once there is high temperature. The odor is generated
from insulation materials decomposing. It is not machine failure. It’s better to have a
high-temperature operation before using.
11. Handling of power cord
 Do not entangle the power cord. This will cause overheating and possibly a fire.
 Do not bend or twist the power cord, or apply excessive tension to it. This may cause a fire
and electrical shock.
 Do not lay the power cord under a desk or chair, and do not allow it to be pinched in order
to prevent it from being damaged and to avoid a fire or electrical shock.
 Keep the power cord away from any heating equipment such as a room heater. The cord's
insulation may melt and cause a fire or electrical shock.
 If the power cord becomes damaged (wiring exposed, breakage, etc.), immediately turn off
the power at the rear of this unit and shut off the main supply power. Then contact your
nearest dealer for replacement of the power cord. Leaving it may cause a fire or
electrical shock.
 Connect the power plug to the receptacle which is supplied appropriate power and voltage.
12. Use of vacuum pump
Place the vacuum pump horizontally.
Regularly spot check the vacuum pump as per its instruction manual.
This unit does not have vacuum breaker system and vacuum pump anti oil backstreaming
system. Please buy the anti oil backstreaming accessories from the vacuum pump agent.
For the purge/pump valve and vacuum pump usage, please carry on as per P34 Vacuumizing
and air inflow.

activated. The unit starts operation again when the
POWER switch is pressed again (manual reset).
2. Calibration offset function
This calibration offset function is for calibrating the
difference occurred between the required in- furnace
temperature and control temperature (sensor
temperature) of the controller. This unit can be
calibrated toward either plus side or minus side of the
whole temperature range.

4. Operation Method
Setting of Overheating Prevention Device
The unit has the overheating prevention device (manual reset) that consists of independent
temperature measurement circuit, CPU, sensor and output circuit (it shares power source, display,
and key input with the controller) in addition to the automatic overheating prevention function (auto
reset) in the controller.
Setting range/function
The unit has failsafe functions against overheating. One of them is built in the controller and
previously set at factory shipment so to be automatically activated when the temperature exceeds the
setting temperature of temperature controller by 12℃, where the heater repeats on and off.
The other is united with the controller, which can be set by operating the keys on the controller.
The setting range of latter is from 0℃ to max set temperature of main controller + 50℃.
In case the temperature in furnace exceeds the setting temperature of controller to reach to that of
overheating prevention device, the circuit is shut off and "Er19" is displayed with blinking on the
screen of controller with buzzer sound. If the device is once activated,"Er19"continues to be displayed
until the power is newly turned on.
Temperature setting procedure 1. Turn on the power (turn on the ELB)
The default value is displayed for about 4 seconds after
turning on the power. The screen then displays the initial
setting. The current temperature in furnace, operation mode
character and setting temperature of overheating prevention
device are displayed on respective screens.
2. Set the temperature for overheating prevention
① Press the SUBMENU key.
② Press the "▼▲" several times to select the setting
character of overheating prevention temperature
"OH" .
③ Press the ENTER key. The current setting temperature is
displayed with blinking on the setting temperature screen.
Note: To prevent improper operation, set the value 20℃
or more over the setting temperature of controller.
④ Select the value using the "▼▲"and then press the
ENTER key. This completes the setting.
Caution
① The standard setting temperature of device is "the maximum setting temperature of unit + 20℃
" or "setting temperature + 20℃". If the unit performs improper operation, increase it 5℃ more.
② Improper setting of temperature may cause inoperative of unit, malfunction of device, e.g. it is
activated during increasing in temperature in furnace, or unexpected accidents such as fire
disaster. To prevent such matters, set a proper value.
The temperature of DP83C/104C is set to 220℃ at factory shipment.
③ The purpose of overheating prevention device is to protect the unit from overheating. It does
not intend to protect the samples, or to protect them from the accident caused by the use of
explosive or inflammability.
