1. Safety precautions

Warning Cautions

Warning

Never operate the unit in an atmosphere containing flammable or explosive gas

Never operate the unit in an atmosphere containing flammable or explosive gas. Otherwise, an explosion or a fire may result since the unit is not explosion-proof.

See section “Never operate the unit in an atmosphere containing flammable or explosive gas. Otherwise, an explosion or a fire may result since the unit is not explosion-proof.” See section “13. List of dangerous materials” on page 36.

Be sure to connect the ground wire.

Be sure to connect the ground wire correctly. Otherwise, electrical leak may result and cause an electrical shock or a fire.

Ban on operation when an abnormality occurs

When a smoke or an unusual odor is seen or sensed, immediately turn the power switch on the main unit off and pull out the power cord (plug) from the power supply. A fire or an electrical shock may result.

Never use electrical power cords bundled.

When these are used bundled, they might overheat causing a fire.

Take care not to damage electrical power cords.

Avoid tightly bend, pull with a strong force or twist to prevent electrical power cords from damaging. A fire or an electrical shock may result.

Never use an explosive or a flammable material with this unit.

Never use an explosive material, a flammable material or a material containing them. An explosion or an electrical shock may result.

See section “13. List of dangerous materials” on page 36.

Never try to touch a hot part.

Some parts of the unit are hot during and immediately after operation. Take special care for possible burning.

Never try to disassemble or alter the unit.

Never try to disassemble or alter the unit. A malfunction, a fire or an electrical shock may result.

Caution

When a thunder is heard.

When a thunder is heard, turn the main power off immediately. A malfunction, fire or an electrical shock may result.

Precautions when installing the unit

1. Carefully select an installation site.

Take special care not to install the unit at a place described below:

On uneven or dirty floor

Where combustible gas or corrosive gas existsWhere the ambient temperature is 35°C or moreWhere temperature fluctuates widely

Where dust or humidity is excessiveWhere subject to direct sunlightWhere vibration is severe

Install this unit at a place with spaces shown below.

2. Never operate the unit in an atmosphere containing explosive or flammable gas

Never operate the unit in an atmosphere containing flammable or explosive gas. Since the unit is not explosion-proof, an arc is discharged when turning a switch “ON” and “OFF” and during operation and a fire or an explosion may result.

See the section “13. List of dangerous materials” on page 36 for flammable and explosive gases.

2. Before operating the unit

Precautions when installing the unit

6. Do not overload shelves.

7. Do not place too many samples.

Withstand load of each shelf board is 15kg in uniform loading. Place samples in a dispersed fashion.

Sample

15kg

Shelf board

Too many samples may prevent proper temperature control. Be sure to use shelf boards and place samples apart each other so as to make free space of 30% or more to assure proper temperature accuracy.

Make at least 30% of space

8. Installation

The unit might fall down or move by an earthquake or an impact resulting a personal injury. We recommend to make safety measures such as to avoid installing the unit at a place other than busy places.

Take appropriate safety measures to prevent the unit from tripping over.

9. Placing shelf boards and samples

Two shelf boards are included with this product. One of them has been fixed on the lowest stage of the shelf pillar of the internal bath at the time of shipping from the factory. Set another board to an appropriate position in the bath.

A heater is installed under the flow adjusting board. Thus, the temperature of the flow adjusting board and around it is always higher than the set temperature and placing a sample directly on the board may damage it or cause a fire. Therefore, the shelf board is fixed with screws as shown to disable direct placement of samples. Because of the shape of samples, when the unit is operated with shelf boards removed to accept them, assure sufficient space between them and the flow adjusting board and never place samples directly on the board.

2. Before operating the unit

Precautions when installing the unit

10. Always operate the unit with the vent holes open.

Do not cover the vent holes on the top panel of the unit.

Adjust the open amount according to the water content of a specific sample.

Adjust according to water content

11. Be sure to connect the power plug to the dedicated power distribution panel or a wall outlet.

Use a power distribution panel or a wall outlet that meets the electrical capacity of the unit.

When the unit will not start even when you turn the earth leakage breaker to “ON”, check for

low main voltage or if the unit is connected to the same power supply line as other devices and connect it to another line if necessary.

Avoid connecting too many devices using a branching outlet or extending a wire with a cord reel or temperature controlling function may degrade due to voltage drop.

Do not connect the unit to any parts or lines other than a correct power supply line such as a gas pipe, a water pipe or a telephone line.

Otherwise, an accident or a malfunction may result.

Precautions when installing the unit

12. Handling of a power cord

Never use electrical power cords bundled. When these are used bundled, they might overheat causing a fire.

Do not convert, forcibly bend, twist or pull the power cord. Otherwise, a fire or an electrical shock may result.

Do not place the power cord under a desk or a chair, or sand between objects to avoid it from being damaged. Otherwise, a fire or an electrical shock may result.

Do not place the power cord close to a stove or other heat generating device. Sheath of the cord may burn and result in a fire or an electrical shock.

If the power cord should be damaged (exposure of core wire or disconnection), immediately turn the main unit off, pull out the power cord (plug) out of the power supply and ask your dealer to replace the cord. Otherwise, a fire or an electrical shock may result.

Connect the power cord to an appropriate wall outlet.

13.Be sure to connect the ground wire.

When there is no ground terminal available, class D grounding work is necessary and please consult your dealer or our nearest sales office.

Be sure to connect the ground wire to the wall outlet securely.

We recommend use of a ground type outlet tap.

When there is no ground terminal.

In this case, class D grounding work is necessary and please consult your dealer or our nearest sales office.

Insert the ground adaptor included as an option, into a power plug confirming the polarity of the outlet. Connect the grounding wire (green) of the ground adaptor to the ground terminal on the power supply equipment.

Never connect the ground wire to anything other than the ground terminal such as gas pipe, water pipe, or telephone line. Otherwise, an accident or a malfunction may result.

14. When you operate the unit for the first time

When you operate the unit for the first time at a higher temperature, the unit may generate an odor. This is due to decomposed bonding material contained in heat-insulation material and is not a malfunction of the unit. We recommend operating the unit at the highest temperature once before starting its regular operation.
