Before Using this unit

Requirements for Installation

7.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: IN603W: 100V AC 15A

NOTE)

Starburst connection with a branching receptacle or extended wiring with a cord reel lowers electrical power voltage, which may cause the degradation of the refrigeration capability or temperature control performance.

8.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.

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.

Before Using this unit

When Using the Unit

CAUTION!

1.Do not use explosive or flammable substance

Never use explosive substances, flammable substances and substances that include explosive or flammable ingredients in this unit. Explosion or fire may occur.

Flammable or explosive substance

2. Do not make an overload

3. 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

4.Notes for some kind of sample

Stainless steel is used for interior; however, it may be corroded by strong acid etc. And the door packing made of rubber may be corroded by some kind of solvent, e.g. alkaline, oil, halogen etc.

Much frost on the evaporator degrades the refrigeration capability, which may cause uncontrollability of setting temperature. Be careful, especially, to treat samples with large water content that generate much frost. Perform the defrost operation if frost is observed through the frost inspection window.

The equipment with large heat load cannot be used because the temperature in furnace increases.

7

Before Using this unit

Defrost in Refrigerator

Much frost on the evaporator degrades the refrigeration capability, which may cause uncontrollability of setting temperature. In the IN603W, the condition of frost on the evaporator can be checked through the frost inspection window inside furnace. The frosting speed varies depending on the following conditions.

1)Temperature used Easily frosted when using the unit in low temperature

2)External temperature/humidity Easily frosted when external temperature/humidity is higher

3)Sample in furnace Easily frosted when sample contains much water

The following operations can be set to take measure against frosting in the IN603W. Set either of them depending on the situation. The fixed temperature and program operation are available there by pressing the DEFROST key on the operation panel, in addition to the program operation.

Manual defrost operation (manual start/automatic stop):

Perform the defrost operation if much frost is in the evaporator. Temperature control is suspended in addition to stop of heater and blast fan during operation. The operation is started manually and stopped automatically with the built-in timer after 5-minute operation.

Refer to the page 44 for the operating instructions.

Cycle defrost operation (Automatic start/stop):

Set the cycle defrost operation to operate the unit effectively for long term. The unit can repeat the defrost operation and operation stop automatically at specified interval specified previously. Frost can be usually removed to perform the cycle defrost operation for ten minutes in a day. The amount of frost varies depending on the conditions. Set it appropriately. Temperature control is suspended in addition to stop of heater and blast fan during operation.

Refer to the page 45 for the operating instructions.

CAUTION!

The temperature in furnace increases about 3 at the defrost operation. Be careful if it affects the samples. The indicated temperature may increase more than 10 at that time.

Setting of refrigeration operation mode in refrigerator (continuous/cycle):

Generation of frost can be reduced by setting the cycle operation where the refrigerator repeats operation and halt. The refrigerator operation mode has a function to set the refrigerator to continuous operation, cycle operation or halt condition. The refrigerator repeats 12-minute operation and 12-minute halt condition in the cycle operation. If the setting temperature is 10 or below, it switches automatically to the continuous operation related to the refrigeration capacity. The refrigerator does not work regardless of setting temperature if it is set to be stopped. Set the continuous operation when considering the accuracy of temperature control important, and set the cycle operation when reducing the mount of frost at long term operation (the accuracy of temperature control lower than that in the continuous operation). The cycle operation can also prevent the samples from drying. Set the refrigerator stop if it is not necessary to be operated (it automatically stops if the setting temperature is 44 or above).

Refer to the page 47 for the operating instructions.

CAUTION!

The frosting amount varies depending on the conditions in use even the cycle operation is set. It may be larger when operating the refrigerator for long term. In this case, defrost the refrigerator by performing the defrost operation or cycle defrost operation.
