SPECIFICATIONS

DECLARATION OF CONFORMITY

INSTALLATION

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

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

Location

1. Place this centrifuge on a firm, flat and level surface, and ensure the four feet of this centrifuge stand on the counter firmly.
2. Avoid installing on a slippery surface or surface prone to vibration.
3. The ideal ambient temperature is 20℃±5℃, avoid placing the centrifuge in direct sunlight if the temperature exceeds 30℃.
4. Keep clear of the centrifuge at least 10cm on both sides and at least 30cm behind it to guarantee cooling efficiency.
5. Keep away from heat or water to avoid sample temperature issues or centrifuge failures. Connection of the power cord and grounding

WARNING
To avoid electrical shocks, ensure your hands are dry when touching the power cord.
This centrifuge must be grounded properly. A minimum 10A outlet providing sufficient ground is required, and this must meet local safety requirements.

STRUCTURE

OPERATION PANEL

Main interface
In the above diagram; the speed is set to 4,500rpm, the door lock is released and the running time is 12 minutes. When the speed symbol is rotating, this indicates the centrifuge is running. If the rotation is faster, the speed is higher. The temperature of the chamber is displayed and cannot be controlled. The time symbol displays the ratio of working to time setting. The total time setting is divided into 10 sections.

Rotor Preparation
CAUTION

• Do not overload samples that may cause leaking.
• Do not exceed the actual capacity allowed in the user manual.
• Keep the tubes balanced
• Although the centrifuge can accept sample balancing by eye, we recommend that you keep this centrifuge in a well-balanced condition to extend its life expectancy.
• Never intentionally run the centrifuge under an unbalanced condition even though the allowable imbalance is not exceeded.

Inspect the rotor
Check the rotor for corrosion or scratches before using it.

CAUTION

• If any abnormality such as corrosion or scratches is found, stop using the rotor and contact our service centre.
• Only the manufacturer’s rotors must be used with the unit.
• Symmetrically load centrifuge tubes into the rotor

CAUTION

• Make sure the rotor lid is securely fixed on the rotor, as well as the rotor and shaft are tightened. Otherwise, the rotor may be moved off while rotating and cause damage to the centrifuge and rotor.
• Firmly tighten the rotor lid to the rotor.

OPERATION

CAUTION

• Do not push or lean against the centrifuge while it is running.
• Do not run the centrifuge when fragments or sample solutions are left in the centrifuge chamber. Always keep the centrifugal chamber clean.
• If the centrifuge makes a strange noise during operation, stop it immediately and contact our service centre. Notify them that the warning code is displayed.

MAINTENANCE

Cleaning
CAUTION

• If you do not follow the recommended instructions for cleaning or disinfecting this may damage the centre.

Continued

• If the centrifuge is exposed to ultraviolet rays for a long time, the colar at the daar may be changed or the label may be one of.
• After wine, cover the centrifuge with a piece of cloth to protect it from direct exposure.
• If the centrifuge needs cleaning, clean it with a cloth or sponge moistened with a neutral detergent solution.
• Sterilize the centrifuge by wiping it with a cloth moistened with 70% ethanol solution.

Raptor 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.
• If the rotor needs cleaning, clean it with a cloth or sponge moistened with a neutral detergent solution. Sterilize the centrifuge by wiping it with a cloth moistened with 70% ethanol solution.

Once shatt
We recommend regular maintenance for drive shalt. You can widen the drive shalt with a soft cloth. and then apply aathin coat of silicon grease.

Door

• Clean and sterilize the door using the same method as section (1) above.
• To prevent corrosion, remove the raptor from the rotor chamber. If not in use for the long term, then detach the rotor lid and turn it upside down to dry the tube holes and keep them clean.
• For sample leaks in the rotor, rinse the rotor with water. Apply a thin coat of silicon grease to the rotor when it is completely crying.
• The rotor should be checked every 3 months to ensure the tube and rotor holes are clean and a thin

TROUBLESHOOTING

Possible problems and solutions
This centrifuge has a self-diagnostic function. If a problem occurs, an error/warning code will be displayed on the time display screen, and the operator can determine the malfunction with the alarm code below. Alarm codes time-y are related to incorrect operation/ programming. You can continue running the contractual sewer implementing corrective procedures.

How to open the door
In the case of power on

CAUTION

1. The door just can be opened while the power is on and the rotor stops rotating.
2. Turn on the power switch, and release the door automatically.
3. The door will be released automatically once the operation is finished.
4. It is possible to release the door by pressing the 000% button once the rotor stops.

In the case of a power outage
The door cannot be opened automatically if there is a power outage. It is available to be opened manually as follows.

1. Ensure that the rotor has stopped rotating.
2. Listen carefully to ensure no rotating sound can be heard.
3. Insert a screwdriver into a hole to open the door.
4. Holes are located on the flat and riant sides of the unit.
5. Insert a screwdriver into the two holes and push forward to release the door.

INSTRUCTIONS FOR THE ROTOR AND TUBES

CAUTION

• Read the instructions thoroughly, to properly load and use the rotor.
• Do not exceed the allowable maximum speed of the rotor, tube adapters etc.
• Ensure the allowable maximum speed of adapters is lower than the rotor’s maximum speed.

Rotor structure
Available rotors and adapters

Notice
The centrifuge rotor can separate samples with a density lower than 2.0g/ml. If the sample density is over 2.0g/ml, please calculate the allowable speed depending on the following formula.

Available rotors and adapters

Notice

• The centrifuge rotor can separate samples with a density lower than 2.0g/ml. If the sample density is over 2.0g/ml, please calculate the allowable speed depending on the following formula.

CALCULATE RCF
An RCF can be determined with the following calculation formula.

• RCF=1.118×r×n2×10-5
• r—rotating radius, unit: cm; n—rotating speed, unit: rpm

AFTER-SALES SERVICE
To ensure the centrifuge is safe and efficient, is necessary for regular maintenance. If centrifuge has problems, do not attempt to repair it by yourself. Contact your supplier.
