The precautions described in this User manual are carefully developed to cover all the possible risks. However, it is also important that you are alert for unexpected incidents. Be carefully operating this centrifuge.

WARNING：

This centrifuge is not explosion-proof. Never use explosive or flammable samples.
Do not install the centrifuge in or near places where inflammable gases are generated, or chemicals are stored.
Do not place dangerous material within 30cm around the centrifuge.
Make sure to prepare necessary safety measures before using samples that are toxic, radioactive or contaminated with pathogenic micro-organisms at your own responsibility.
If the instrument, rotor and/or accessories that has been contaminated by solutions with toxic, radioactive or pathogenic materials, clean it according to the decontamination procedure that you are specified.
If you require services at site, please sterilise and decontaminate it in advance, and then notice the service centre involved in the details of the particular materials.
Do not handle the power cord or turn on or off the POWER switch with wet hands to void electrical shocks.
For safety purposes, do not enter within 30cm around this centrifuge while it is in operation.
While the rotor is rotating, never forcedly release the door lock.
Unauthorized repairs, disassembly, and other services to the centrifuge except by our service centre are strictly prohibited.

CAUTION

This centrifuge must be located on one firm and level table.
Make sure the centrifuge is horizontal before running.
Make sure the angle between the door and cover is greater than 70 degrees when open the door.
Be careful not to put your fingers or hands between the door and cover when the door is off.
Do not move or relocate this centrifuge while it is running.
When there is fluid in the rotor chamber, please promptly dry with a dry cloth to avoid sample contamination.
Ensure to remove any objects and fragments of the tubes dropped inside the rotor chamber before running this centrifuge.
Caution on rotors
- Always check for corrosion and damages on the rotor surface before using it. Do not use the rotor if such abnormality found.
- Do not set the centrifuge speed override the allowable minimum speed of the rotor kits (rotor or the other adapters). Make sure to run it below the allowable minimum speed.
- Do not allowable imbalance.
- Use the rotor and tubes within their actual capacities.

SPECIFICATIONS

MAXIMUM SPEED 300 – 5,000 RPM

INSTALLATION

This section describes the instructions that you should abide by when installing the centrifuge to ensure your safety and the optimum performance. Before moving the centrifuge, the rotor must be removed.

WARNING：

Incorrect power supply may damage centrifuge.
Make sure the power source conforms to the required power supply before connecting.

Location

Locate this centrifuge on a firm, flat and level table; ensure the four feet of this centrifuge stand on the table firmly. Avoid installing on a slippery table-board that conveys vibration.
Ideal ambient temperature is 20℃±5℃, avoid placing the centrifuge in direct sunlight if temperature exceeds 30℃.
Keep clearances of at least 10cm on both sides of centrifuge and at least 30cm behind it to ensure its cooling efficiency.
No heat or water resource nearby, otherwise easily cause sample temperature increase or centrifuge failures.

Connection of the Power Cord and Grounding

WARNING：

Do not touch the power cord with wet hands to avoid electrical shocks.
This centrifuge must be grounded properly.

This centrifuge is equipped with a 3P flat plug; grounding can be done just by plugging the 3P plug into the outlet.
A cover 10A outlet which has a good ground is required and meets with local safety requirements.

OPERATION

fig-1

Open the lid and switch on the on/off switch (located back of the unit).
Symmetrically load centrifuge tubes to rotor.
Close the centrifuge lid to begin running.
Switch off, the rotor will gradually stop.
Open the lid and remove samples when the rotor has completely stopped.

Rotor Preparation

Prepare the samples to be separated
Place samples into the centrifuge tube：The amount of sample should not exceed the allowed maximum amount set forth in this user manual.
Ensure the balanced centrifuge tube
Rotor installation and replacement
Insert the centrifuge tubes symmetrically onto the rotor in place without imbalance

Program P1/P2: Press P1/P2 key to enter the fixed program, press P1/P2 key for 5 seconds to enter the program setting interface, press the P1/P2 key to switch the spinning speed, time, centrifugal force, and adjust the parameters by rotating the knob. The parameters are automatically saved after the setting is finished for 7 seconds; the parameters of the setting can be memorized and saved, and automatically recalled when the machine is turned on again.
Set operating parameters: Press the knob to select the parameter Speed, RCF or time and rotate to input or modify accordingly.
Set the rotation speed: Press the Select key to choose the rotation speed, adjust the parameter value in rpm. The minimum rotation speed is 300rpm, the minimum increment is 10rpm. Set the run time: Set the time parameter value to desired setting within the range of 30s-99min. When the time displays HD, this is a continuous running mode.
Switch the deceleration speed: Press the knob for 5 seconds and after sound reminder, switch between 1 and 2 steps.

Start Run

Press Start button to start running
View and modify the operation programs

Operation programs can be modified after the centrifuge reaches the set speed. Pressing the knob to return the program interface and displays setting programs. Press the knob and when parameter flashing, rotate knob to modify values. Release the button after 5 seconds, and the centrifuge will return to normal operation mode and run according to the new value.

Stop running
When the set run time is completed, the centrifuge stops its run operation automatically or it can be stopped by pressing the . Open the outer lid to remove the samples and rotor.

Open the door manually

If power is off by accident, the door can be opened manually by sliding the switch to right which is at the bottom right front side.

MAINTENANCE

Not following the recommended instructions for cleaning or disinfecting may damage the centrifuge.

Centrifuge

If the centrifuge is exposed to ultraviolet rays for a long time, the colour of the doors may change and/or the label may come off. After using, cover the centrifuge with a piece of cloth to protect it from direct exposure.
Once the centrifuge is heavily dirty, clean it with a cloth or sponge moistened with a neutral detergent solution.
Sterilise the centrifuge by wiping with a cloth moistened with 70% ethanol solution. Rotor chamber

CAUTION： Do not directly pour water, neutral detergent or disinfectant solution into the rotor chamber. Otherwise, fluids may leak into the drive units and cause corrosion or deterioration to the bearings.

Once the rotor chamber is dirty, clean with cloth or sponge moistened with a neutral detergent solution. Sterilise the centrifuge by wiping with a cloth moistened with 70% ethanol solution.

Door

Clean and sterilise the door using the same method as the step 1.

Rotor

To prevent corrosion, remove the rotor from rotor chamber. If do not use regularly then detach the rotor door and flip the rotor to dry the tube holes.
If a sample is leaked in the rotor, rinse the rotor with water. Apply a thin coat of silicon grease to the rotor when it is completely dried.
The rotor should have regular maintenance, its recommended cleaning it each 3 months to ensure tube and rotor holes keep clean, and then apply a thin coat of silicon grease.
