Before Using this unit Requirements for Installation WARNING! 1. Always ground this unit • 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.
Before Using this unit Requirements for Installation 4. 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 63 "List of Dangerous Substances".) 改造 5. Do not modify 6. Installation on horizontal surface • Set this unit to the flattest place.
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: IN603: 100V AC 10A, IN803: 100V AC 12A 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.
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 temperature in furnace cannot be controlled if too much samples are set there.
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 IN602 or IN802, 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.
