4

Before Using This Unit

Requirements for Installation

4.Secure the ventilation of device

Do not operate while the device side/back is obstructed. The temperature inside the device rises and may become the cause of an accident, a failure and a fire.

5.Do not use in the place that the device is exposed to liquid

Do not operate in the place that the device is exposed to liquid. If liquid go inside of the device, it will become the cause of an accident, failure, an electric shock, and a fire.

6.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.

 

To know about flammable or explosive gas, refer to page 59 “List of Dangerous Substances”.

5

Before Using This Unit

Requirements for Installation

CAUTION!

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: BB300: 100V AC, 12A BB400: 100V AC, 13A BB600: 100V AC, 20A

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.

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

Connect the unit to only the power supply. If it is connected to a gas pipe, water pipe or telephone line, an accident or malfunction may result.

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.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.

Please consult your local electrical contractor for power connecting work.

Before Using This Unit

Installation Procedure

6Precautions about the circulating path

Carefully check the direction of circulation, and connect the hoses properly. Improper connection results in an accident or malfunction of the unit and the circulating path.

Minimize the length of the circulating path. If resistance inside the piping increases, the quantity of circulating fluid decreases, resulting in lower cooling efficiency. For the capacity of the circulating pump, see "Cooling curve, cooling capacity curve (reference data)" on page 39.

Be sure to connect for making a circulating route. Do not connect with water service or gas pipe, etc. It may cause an accident or a failure.

Check the circulation capacity and withstand pressure of the circulating path. Excessive circulation or pressure may result in an accident or malfunction.

Do not connect any powered unit or a unit with a motor to the circulating path. It may cause an accident or failure.

When changing flux, execute the operation slowly. A rapid change of flux may damage the durability of the pump.

If the unit is to be connected to a circulation unit installed in a higher place than it, beware of the backflow of the circulating fluid. If the fluid flows back, it may overflow the water bath of the unit. Add a valve to the circulating path or take other proper measures to prevent a backflow.

7Connecting the power.

Confirm that the earth leakage breaker is turned off, then connect the power plug (BB300/400 type) and the circle terminal (BB600 type) to switchboard or receptacle.

8Pour circulating fluid into the bath.

Turn on the earth leakage breaker and RUN/STOP key, and circulate the fluid.

In external sealing system connection, open the discharge valve for circulation and circulate to the device of external sealed system to be cooled. After it is stabilized, supply circulating fluid to the proper level shown as below.

After the resupply of the circulating fluid, turn "off" the leakage breaker.

Caution) Slowly pour the circulating oil.

Exercise care not to allow the circulating fluid to get on the unit. If it gets on any electric part, leakage or electric shock may result. If it splashes on the operation panel, wipe it out.

Operation Mode, Function Setting Key, and Characters

The operation mode setting and function setting use the key operation and characters show in the following figure.

14

Operation Method

Setting of Overheating Prevention Device

The unit has the overheating prevention device (manual reset) that consists of independent temperature measurement circuit, CPU, sensor and output circuit (it shares power source, display, and key input with the controller) in addition to the automatic overheating prevention function (auto reset) in the controller.

Setting range/function

The unit has failsafe functions against overheating. One of them is built in the controller and previously set at factory shipment so to be automatically activated when the temperature exceeds the setting temperature of temperature controller by 6 , where the heater repeats on and off.

The other is united with the controller, which can be set by operating the keys on the controller. The setting range of latter is from 0 to 50 .

In case the temperature in bath exceeds the setting temperature of controller to reach to that of overheating prevention device, the circuit is shut off and "Er19" is displayed with blinking on the screen of controller with buzzer sound.

If the device is once activated,"Er19"continues to be displayed until the power is newly turned on.

Temperature setting procedure

Notes:

1.Turn on the power (turn on the breaker in front)

The default value is displayed for about four seconds after turning on the power. The screen then displays the initial setting. The current temperature in bath, operation mode character and setting temperature of overheating prevention device are displayed on respective screens.

2.Set the temperature for overheating prevention

Press the SUB MENU key.

Press the " ▼▲" several times to select the setting character of overheating prevention temperature "OH".

Press the ENTER key. The current setting temperature is displayed with blinking on the setting temperature screen.

Note: To prevent improper operation, set the value 10 or more over the setting temperature of controller.

Select the value using the " ▼▲"and then press the ENTER key. This completes the setting.

The standard setting temperature of device is "the maximum setting temperature of unit plus 10 " or "setting temperature plus 10 ". If the unit performs improper operation, increase it 5 more.

The setting range of overheating prevention device is from 0 to 50 . Improper setting of temperature may cause inoperative of unit, malfunction of device, e.g. it is activated during increasing in temperature in bath, or unexpected accidents such as fire disaster. To prevent such matters, set a proper value.

The temperature is set to 90 at factory shipment.

The purpose of overheating prevention device is to protect the unit from overheating. It does not intend to protect the samples, or to protect them from the accident caused by the use of explosive or inflammability.
