Operation
• Remove the contents from the package examining them carefully for breakage, defects or
missing parts.
• Place the product on a sturdy, level surface at least 300mm away from the edge of the
counter and other moving equipment. Make sure the AC power adapter and cords are clear
of hot surfaces and other hazards.
• Make sure the product has ventilation and is not encased in any material that will limit
airflow. An overheating situation could occur.
• Verify that the power switch in the back of the unit is in the OFF position. Plug the DC cord
into the rear of the unit and the AC cord into an approved outlet.
• ONLY use Heathrow Scientific supplied power adapter and cords.
Prior to using
• Before every use, inspect unit for cracks, missing pieces, and or any damage that would
result in an impaired performance and notify manufacturer BEFORE use.
• Turn power switch on the rear ON. The unit will initialize.
• Press the OPEN button. The lid should pop up slightly. Lift the front of the lid gently up and
backward until approximately 90 degrees vertical.
• Remove any remaining packaging materials.
• Verify that the rotor is installed correctly. (see section Rotor Installation and Removal) Do not
run without the rotor installed.
• Close the lid.
• Press the START/STOP button (rotor should spin up to the preset speed). If there is a smooth
whirring sound and the unit accelerates with little or no vibration, the mini-centrifuge is ready
to use. If there are loud or unusual sounds, or excessive vibration, DO NOT OPERATE.
Contact Heathrow Scientific service.
• At the set time, the rotor will spin down, stop and the unit will emit a beep when the cycle is
complete.
