1. Safety Instructions

Connect the device to an earthed socket to ensure the safety of the machine

and the experiment. Make sure the voltage is the same as required by the

device.

The use of this instrument in flammable, explosive, poisonous, or highly

corrosive environments or with hazardous substances is forbidden.

Place the incubator on a horizontal, flat, clean, non-slip and stable surface.

Adjust the feet so that the device is leveled.

This item must only be used by qualified staff that has read the instructions

manual and knows how to operate it.

Do not place the device near any heat source. Keep away from high

magnetic fields. Do not put volatile, flammable and explosive materials in

the machine, otherwise it could cause an explosion or a fire.

Non-professionals must not disassemble or repair this machine.

Read the instructions manual before using this device.

·When working, wear the necessary personal protective equipment to avoid the risk of:

-Burns caused by contact with hot surfaces or materials

-Burns caused by splashing and evaporation of liquids

-Intoxication caused by release of toxic or flammable gases

·The device and accessories must be checked prior to every use. Do not use damaged

components.

·Beware of hazards due to:

-Flammable materials or media with a low boiling temperature

-Overfilling of vessels

-Unsafe vessel

·Do not cover the device.

·Do not expose the device to rain, moisture or splashing as this might result in electrical leakage,

short-circuit or electric shock.

·In case the device is let idle or unsupervised, ensure the door is completely closed.

·Unplug by pulling always from the plug. Never pull from the wire.

·Do not connect the power cord to the middle section.

·Ensure that the main cable does not touch the surface.

·Do not damage the power cord and always use the specified one. In case of damage, the

power cord must be replaced.

·Do not unplug the power cord during operation.

·Unplug the cord before maintenance, after use, and if the instrument is running abnormally.

·Do not touch the power plug with wet hands.

·Wear gloves when repairing and maintaining the instrument.

Other necessary considerations:

·When touching the inner wall of the door, do it carefully, as it may be hot.

·The internal parameters must be set by the specific management person to prevent the function

of the controller program from being disturbed by an unknown setting.

·The equipment must be placed at least 20cm away from the wall and from any objects.

·Open and close the door gently to prevent damage to the equipment.

·Do not expose the equipment surface to volatile chemicals.

·Keep the equipment clean, both the inside and the outside.

Safety alarms:

·In case of a controller block, Holzer error, busbar under voltage, busbar over voltage or

communication failure, the speed bar will show the fault code and the controller will

automatically stop.

·In case of a temperature or speed alarm, the identifier ALM1 will light up and the buzzer

sound will go off. Stop it by pressing any key.

·When turning off the equipment, always press to stop any ongoing functions before

turning off the device.

·In case of a fault of the temperature sensor or the controller itself, the indicator –will display.

Carefully check the temperature sensor and its wiring.
