General Purpose Incubator BOHA-317

1. Application

A constant temperature and humidity chamber is thermostatic equipment with heating, cooling and humidification function, highly precise and advanced. Widely used in plant cultivation, breeding test, bacteria, mold, microbial cultivation & preservation, BOD determination and so on. Which is also used in biological genetic engineering, medical treatment, health and epidemic prevention, medical test, agriculture and animal husbandry, aquatic and other scientific research institutions.

2. Performance

Constant temperature and humidity transfers actual temperature and humidity detected from temp. sensor and humidity sensor into signal. Through microcomputer control to heater towards required temperature and humidity.

5. Equipment installation

In order to make sure the equipment can run normally, please place equipment as following:

Attention: ambient temperature 10~30°C ;relative humidity less than 70%

1. Avoid exposure to the sunlight.

Do not place it in direct sunlight, or it won't reach predicted performance

2. An efficient vent place

If you operate this equipment in a narrow and concealed room, it may lead to

over-heating and malfunctioning. Minimum safe distance between equipment and wall is 10CM

3. Keep away from heat source

Don't install the equipment near heating source. External excess heat will affect performance of the equipment and may cause malfunctioning

4. Flat and firm ground

Make sure to install it in flat and firm ground. Uneven surface or leaning installation may damage equipment or injure people. Proper installation can avoid shaking and noise

5. Avoid humid place

Install the equipment in a place where humidity is less than 70%. Otherwise it may cause short-circuit or electric shock.

Warning

Do not place this equipment outdoors. If it exposed in the rain, it may cause short-circuit and electric shock.

Do not place equipment in humid environment or a place with dripping water. Otherwise it may cause short-circuit or electric shock.

Avoid place with flammable or corrosive gas.

Do not place equipment near flammable materials and volatile substance. Otherwise it may cause explosion or fire. Do not place equipment in the place where has acidic and corrosive gas, or corrosion will cause short-circuit, electric shock or equipment damage.

6. Installation

1. Unpacking

Remove packing materials ,open the door for ventilation. Please use neutral detergent to clean if the shell and panel is dirty. then wipe with wet cloth and at last with dry and clean cloth

2. level equipment

Fix equipment with the front brake-wheel after installation in case equipment moves

3 Earthing

Warning

Please use power socket that has protective conductor terminal in case of electric shock. If it is not connected, has to install protective conductor terminal by licensed technician.

Do not connect protective conductor terminal through gas, water pipe, telephone line or lighting arrester which will cause electric shock.

4. Idle equipment

Before setting equipment aside , empty water in the humidifier and remove internal, moisture thoroughly. Be sure the inner chamber is dry and cool before closing the door .

5. Move equipment

Before moving equipment ,empty water in the humidifier .or it will cause creepage or electric shock because of overflow water or splashed water.

7. Preparation before Operation

When equipment running in the first time, please operate as below:

1.Take out the shelves or other accessories

2.Clean the inner wall with gauze which is soaked by alcohol and then use dry cloth to wipe-dry

3.Put the shelves into inner chamber according to your experiment of requirement

4.Put water tank on the top of equipment before using ,please connect water pipe with water inlet and overflow outlet which in the left of equipment (refer to component picture ) ,and put storage water tank under the overflow pipe and water outlet for spare use

5.Pour enough pure water into water tank

Notice :don't use NaCl or other Halide solution to clean equipment ,or it will cause rust.

PRO----total program number, CYC----total cycle number.

4. Fault reminder:

Temperature alarm:symbol"°C"flashes quickly when upper deviation occurs,symbol"°C"flashes slowly when lower deviation occurs;

Humidity alarm: symbol"%RH"flashes quickly when upper deviation occurs,symbol"%RH"flashes slowly when lower deviation occurs;

If the (3) area displays "---",user should check the sensor and controller.
