Cautions in Using with Safety

Fundamental Matters of "WARNING!" and "CAUTION!"

WARNING!

Do not use this unit in an area where there is flammable or explosive gas

Never use this unit in an area where there is flammable or explosive gas. This unit is not explosion-proof. An arc may be generated when the power switch is turned on or off, and fire/explosion may result. (Refer to page 71 "List of Dangerous Substances".)

Always ground this unit

Always ground this unit on the power equipment side in order to avoid electrical shock due to a power surge.

If a problem occurs

If smoke or strange odor should come out of this unit for some reason, turn off the power key right away, and then turn off the circuit breaker and the main power. Immediately contact a service technician for inspection. If this procedure is not followed, fire or electrical shock may result. Never perform repair work yourself, since it is dangerous and not recommended.

Do not use the power cord if it is bundled or tangled

Do not use the power cord if it is bundled or tangled. If it is used in this manner, it can overheat and fire may be caused.

Do not process, bend, wring, or stretch the power cord forcibly

Do not process, bend, wring, or stretch the power cord forcibly. Fire or electrical shock may result.

Substances that can not be used

Never use explosive substances, flammable substances and substances that include explosive or flammable ingredients in this unit. Explosion or fire may occur. (Refer to page 71 "List of Dangerous Substances".)

Do not disassemble or modify this unit

Do not disassemble or modify this unit. Fire or electrical shock or failure may be caused.

Do not touch high-temperature parts

The inside of the body or the door may become hot during and just after operation. It may cause burns.

CAUTION!

During a thunder storm

During a thunderstorm, turn off the power key immediately, then turn off the circuit breaker and the main power. If this procedure is not followed, fire or electrical shock may be caused.

Before Using this unit

Requirements for Installation

WARNING!

1.Always ground this unit

The DNF400 and DNF600 types use a 100V power source.

The DNF600 type does not contain a power plug. Please consult your local electrical contractor for power connecting work.

The DNF410, DNF610, DNF810 and DNF910 types use a single-phase 200V power source. Please consult your local electrical contractor for power connecting work.

Be sure to connect the earth wire (the green cable of power cord) to the grounding conductor or ground terminal to prevent accidents caused by electric leakage.

Do not connect the earth wire to gas or water pipes. If not, fire disaster may be caused.

Do not connect the earth wire to the ground for telephone wire or lightning conductor. If not, fire disaster or electric shock may be caused.

Do not use a branching receptacle, which may cause the heat generation.

2.Choose a proper place for installation

Do not install this unit in a place where:

Rough or dirty surface.

Flammable gas or corrosive gas is generated.

Ambient temperature exceeds 35°C.

Ambient temperature fluctuates violently.

There is direct sunlight.

There is excessive humidity and dust.

There is a constant vibration.

Install this unit on a stable place with the space as shown below. The exhausted opening is provided on the back surface. Keep away from it during operation.

Before Using this unit

Requirements for Installation

4. Do not modify

5. Installation on horizontal surface

Modification of this unit is strictly prohibited. This could cause a failure.

Do not modify

Set this unit to the flattest place. Setting this unit on rough or slope place could cause the vibration or noise, or cause the unexpectible trouble or malfunction.

CAUTION!

6. Do not make an overload

7. Do not set samples in close formation

The withstand load of shelf is 15kguniform load Set the samples apart each other.

Samples

15Kg

Shelf

The temperature in furnace cannot be controlled if too much samples are set there. Make sure to use the shelf and set samples apart each other so as to make the free space of 30% or more to the furnace to acquire accuracy of temperature.

Make the free space of 30% or more

Before Using this unit

Requirements for Installation

8.Do not use corrosive sample

Stainless steel SUS304 is used for the main hot-air path; however, it may be corroded by strong acid etc. And the door packing made of silicon rubber may be corroded by some kind of solvent, e.g. alkaline, oil, halogen etc. Do not use the sample includes those.

9.Choose a correct power distribution board or receptacle

Choose a correct power distribution board or receptacle that meets the unit’s rated electric capacity.

Electric capacity:

 

 

 

DNF400:

100V AC, 13.5A

DNF410:

1φ200V AC, 7A

DNF810: 1φ200V AC, 15A

DNF600:

100V AC, 16A

DNF610:

φ

DNF910: 1φ200V AC, 18A

 

 

1 200V AC, 8A

 

NOTE)

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. Please consult your dealer or a local electrical contractor for the connection of DNF600 and devices that use a single-phase 200V power source.

10.Handling of power code

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.

11.Before/after installing

It may cause injure to a person if this unit falls down or moves by the earthquake and the impact. etc..To prevent, take measures that the unit cannot fall down, and not install to busy place.

Touching the unit may cause a burn during and just after the operation. To prevent, take measures that putting up a notice of operating etc..

Make sure to lock the caster for DNF810 and DNF910 types.

Before Using this unit

Requirements for Installation

12.Setting of the shelf and sample

The number of shelves attached varies depending on the type of product (2 to 8).One of them (two for DNF910) is previously fixed on the lowermost stand of bracket supporter with screws at factory shipment. Set the other shelves in place in furnace as necessary.

One of the shelves is fixed on the lowermost stand of bracket supporter with screws at factory shipment. The temperature of the current plate and its adjacence is usually higher than the setting temperature because the heater is provided under it, which may cause burn of sample or fire disaster if the sample is directly put on the current plate. Do not shut the slit on near side of current plate with samples because it is an inlet slit on the circuration circuit of hot air,

with samples. To prevent such accidents, the shelf is fixed with a screw as shown in the figure. Be sure to provide sufficient space between the current plate and sample in case the shelf must be removed due to the shape of sample. Do not put the sample directly on the current plate.

The countdown of timer is suspended when the temperature in furnace is 3 or more lower than the setting temperature, or 6 or more higher

than it. In this case, the Sub Display displays "Wait" with blinking. The time display on the right side of "Wait" shows the total waiting time in operation.

The operation stops when the residual time counts zero. The END lamp blinks and the Sub Display displays the operation finish time when the operation stops.

The wait function is not activated when the auto stop operation is carried out with "Clock" mode. The operation stops at specified time.

The fan stops at the same time the operation finishes when "OFF" is selected at fan function.

The setting of fan function ["ON"/"OFF"] takes priority, regardless of setting for fan operation in the standby state.
