Before Using this unit

Requirements for Installation

CAUTION!

6. Do not make an overload

7. Do not set samples in close formation

The withstand load of shelf is 10kguniform load Set the samples apart each other.

Samples

10Kg

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

8.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:

IJ201:

100V AC, 4.5A

 

IJ300:

100V AC, 9.0A

IJ300W: 100VAC, 11A (Service socket 2A)

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.

In use of a service socket, please use it in the way within 2A.

9.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..

10.Setting of the shelf and sample

Before Using this unit

Requirements for Installation

11.Drain of dew drops

Use the attached tray for drain of dew drops. They may occur inside the furnace or around the door packing depending on environmental condition or samples used when the cooling device is operated.

12.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.

4.Pull off the guide pin fixing the upper part of the door, and insert it into the screw hole on the opposite side (right side).

5.Turn the door 180 degrees, and insert it into the upper guide pin.

6.After adjusting the door position, fix the hinge in the lower part of the door.

7.Replace the main body to complete the procedure.

1.Lay down the main body.

4.Remove the guide pin, and move it to the right side.

2.Remove the lower hinge and move it to the right side.
