SAFETY INSTRUCTIONS

Read the operating instructions in full before starting up and follow the safety instructions.

• Socket must be earthed (protective ground contact) before use.
• Water must be filled into the chamber before power-on.
• Avoid operating the bath without water.
• The symbols below are marked on the equipment and in this manual to indicate:

Caution: Surfaces can be hot during and after use
Caution: Socket must be earthed (protective ground contact).

5. Water bath
6. Base tray

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. It has a vent/thermometer hole–this hole should not be sealed as pressurecould build up inside the bath.

3.2 Instrument placement
Place the water bath on a level, non-combustible surface. Ensure that the main 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.

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 the protection 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. 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.
4.3. 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.

4.4. 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

CALIBRATION

6.1. Calibration condition

1. The accuracy of the thermometer should be more than 10 times that of the 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 30 minutes before calibrating.

6.2. Dual point calibration
Due to the influence of ambient temperature, humidity, and pot structure, the water bath has a certain deviation in temperature measurement. In order to improve the measurement and control accuracy, each single instrument is calibrated before shipment. Includes two calibration options — low temperature point and high
temperature point. Low temperature point: 30 ~ 40°C High temperature point: Above 55°C
Low temperature point calibration:
For example:
Before calibration, the screen displays 32.0°C but the actual liquid temperature is 37.0°C
After calibration, the screen displays 36.8 ºC and the actual liquid temperature is 37.0 ºC

Operation| Display|
---|---|---
SET| °C| Select the menu option
| LCP| Select the low temperature point calibration setting menu option
SET| 32.0| Press set to enter the calibration value
| 37.0| Enter the reference thermometer value
SET| SET| Press set to store the calibration value
The setting will exit automatically after 5S without operation

| 36.8| Leave the bath to stabilize and check the calibration

High temperature point calibration:
For example: Before calibration, the screen displays 60°C but the actual liquid temperature is 65.0°C;
After calibration, the screen displays 64.7°C and the actual liquid temperature is 65.0°C;

Operation| Display|
---|---|---
SET| °C| Select the menu option
| HCP| Select  the  high   temperature  point    calibration setting menu option
SET| 60.0| Press set to enter the calibration value
| 65.0| Enter the reference thermometer value
SET| SET| Press set to store the calibration value The setting will exit automatically after 5S without operation
| 64.7| Leave the bath to stabilize and check the calibration
