The instrument should be protected from mechanical shocks and any liquids getting on its
case.
To keep thermal block matrix and elements of the optical system clean, the instrument
thermal block has to be always closed (except operations for placement / removal of PCR
tubes with samples).
Caution!
To avoid failure of the instrument’s optical system it is strictly forbidden to use any
substances (heat-resistant pastes, oils, etc.) to improve contact between PCR tubes and
thermal block wells.
5.2 Maintenance Procedure
The following procedures should be carried out by qualified personnel with a periodicity
specified below:
1) Visual inspection of the instrument to assure the absence of damages on its surface. The
condition (integrity) of the power cord and its reliable connection to the instrument.
Frequency of visual inspection: before each switch-on.
2) Timely removal of some dust / dirt from the instrument’s surface by using disinfectant
solutions in accordance with regulations settled in an institution. Frequency: as and when the
instrument gets dirty.
3)
The exterior and functional surfaces of the instrument should be periodicity treated with
disinfectant solutions to eliminate possible contamination of it by amplification products of
nucleic acids in accordance to local regulations and rules. Cleaning of thermal block wells
has to be done by a cotton swab wrapped on a wooden rod and moistened with no less than
70-% ethanol.
Caution!
Never use any metal objects (paper-clips, wire, etc.) for wells cleaning!
Attention !
When cleaning the wells and thermo block matrix do not allow a liquid
flowing inside of the thermal block and the instrument!
Cleaning frequency: after 20 executed RUNs image of thermal block matrix should be
checked for all channels (as it is described in point 4.2 of the present manual). In case of some
bright spots will be detected for any ranges of fluorescence registration, cleaning of the wells
have to done.
5.3 Disinfection requirements of the instrument prior to maintenance and
repair procedures.
The user is responsible for the proper usage of the instrument as well as for its disinfection
procedures before carrying out maintenance or repair operations.
Prior sending the instrument for repair or maintenance to local servise office or manufacturer
it is necessary to perform the disinfection operations with accordance to local rules and
regulations and fill out the disinfection certificate (see Appendix 1).
