•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.

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: |

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.
