Chapter 5 Instrument Maintenance
5.1 Instrument cleaning
(1) Instrument surface cleaning: the surface of the instrument should be scrubbed regularly with a soft cloth with 75% alcohol, and the instrument should be wiped dry after cleaning.
(2) Reaction wells cleaning：
a. Dust or impurities in the reaction wells can affect PCR amplification and fluorescence detection, and regular cleaning is recommended.
b. To prevent dust from entering the reaction wells, the flip-up cover must be closed when the instrument is not in use.
c. If any reagent enters the sample well, it should be wiped clean with a dust-free soft cloth with anhydrous ethanol.
d. The power must be turned off and the power cord unplugged before cleaning the instrument.
e. Do not pour liquids into the reaction module or inside the instrument.
f. Do not use corrosive solvents or organic solvents to scrub the instrument.
5.2 Instrument protection
(1) Do not switch the instrument on and off frequently.
(2) Please use the adapter provided by the original manufacturer.
(3) Boiling water bath or low temperature holding on the instrument is prohibited.
(4) It is forbidden to disassemble the instrument by non-original maintenance personnel.
5.3 Waste disposal
(1) After each experiment, there are a large number of amplification products in the test tube, which should be disposed of as soon as possible according to relevant regulations to avoid contaminating the laboratory and instruments.
(2) Do not open the cover of the test tube after it is removed from the instrument, otherwise it will easily cause laboratory contamination.
5.4 Overheat protection
(1) When the temperature value of the instrument temperature control module exceeds the set threshold (120°C), the device will automatically stop heating up and force all ongoing actions to stop.
(2) After the above-mentioned failure of the heating system, the user should stop using the instrument and promptly contact the manufacturer or distributor for maintenance.
5.5 Operation requirements
(1) The use of the instrument, the operator may come into contact with harmful substances or infectious substances, the operator needs to have relevant training and relevant qualifications.
(2) The operator should operate the instrument in strict accordance with the relevant national regulations.
