3. INSTALLATION

3.1 Assembly of the equipment and components

The water bath has three main components, the bath, the lid

and the base tray. The base tray fits into the bath with the feet

downward so that it creates a gap between the bottom of the

chamber and the tray.

Note:

1. For optimum temperature stability, avoid allowing the base

tray and sample container to touch the sides of the chamber

while operating.

2. The lid should only be lifted by the handle, as other parts can

become hot during use.

3. It has a vent/thermometer hole–this hole should not be

sealed as pressure could build up inside the bath.

3.2 Instrument placement

Place the water bath on a level, non-combustible surface.

Ensure that the mains plug and the switch are easily accessible.

3.3 Electrical supply

• Check that the supply voltage marked on the serial number

label, and the type of mains plug, are correct for your mains

supply outlet, which must have a ground connection.

• To disconnect the equipment from the mains supply, remove

the mains plug from the mains supply outlet.

4. CORRECT USE

4.1. Avoid operating the bath without water

• Avoid using your bath without water in the chamber. Dry-start

will affect the service life of the key component.

• The bath has an inbuilt protection mechanism known as dry

start protection which will detect this condition in most

circumstances and prevent the bath from continuing to heat.

In this instance the bath will display “ ” and sound an

alarm. If theprotection program fails to detect the dry-heating,

built-in safety temperature cut-out switch will cut off the heating

to protect the water bath when heated to a certain temperature .

Note:

The dry-start protection program is on by default. If you need to

turn it off, please refer to 5.8. Setting the dry-start protection alarm.

The chamber internal surface can become very hot if an

accidental dry start has occurred, even if the dry start cut out

has operated. Avoid touching the chamber until it has been left

to cool.

4.2. Filling the baths

For safe use, please do not fill the bath with water during heating

process. Please turn off the power first if you need to add water.

If filling water triggers a safety warning during the heating process,

please restart the machine to dismiss the warning.

4.3. Emptying the baths

Before emptying any bath, disconnect the device from the power

supply and pull out the plug. Then allow the water temperature

to fall to a safe level and take reasonable precautions to prevent

accidental spillage.

The drainage operation is as follows：

1. Insert the drain pipe into the drain port according to the

direction shown in the figure.

① Drain pipe

② Drain port

2. After draining, loosen the lock of the drain port in the direction

of the arrow as shown in the figure, and then quickly pull out

the drain pipe.

4.4. Using transparent lid

• When the setting temperature is above 60°C , use the lid to

maintain proper temperature control and ensure that the water

temperature reaches the set point.

• The lid will also prevent excessive evaporation that requires

the bath to be filled more often and will save energy.

4.5. Using base tray

• Using the base tray can improve temperature control inside

containers.

• Don’t put the containers or other items into the stainless-steel

chamber directly. Avoid the containers or other items direct

contact with the inside walls of chamber.

are required:

1. The accuracy of the thermometer should be more than 10 times

that of the water bath display.

2. At a stable ambient temperature (+/-1°C) without air convection.

3. Wait for the liquid to reach the calibration setting temperature

and stabilize for 30 minutes before calibrating.

4. Add water to the water bath to 50 mm above the tray, and place

the thermometer in the center of the water bath, 40 mm away

from the tray.
