8.4 Defects and abnormal stresses
Whenever it is likely that the protection has been impaired, the instrument
should be made inoperative and be secured against any unintended operation.
The protection is likely to be impaired if, for example, the instrument:
1. Shows any visible damage
2. Fails to perform the intended functions
3. Has been subjected to prolonged storage under unfavorable conditions
4. Has been subjected to severe transport stresses
8.5 Before operation
Read this manual in its entirety, as it contains information necessary to ensure
safe operation.
8.5.1 Installation
The instrument should be unpacked and installed in accordance with Chapter 5.
Particular attention should be paid to the correct fitting of the tubing to obviate
leaks (Fig. 5.11). Always ensure that the electrical supply in the laboratory
conforms to that specified on the voltage label on the rear panel of the pump
unit.
8.5.2 In operation
Ensure that the waste bottle is emptied regularly and at least every time that a
wash bottle is loaded. The liquid trap bottle that prevents liquid from entering
the pump should be kept dry at all times.
8.6 Cleanliness
Clean the instrument regularly as stated below.
1. It is recommended that the case of the instrument is cleaned periodically to
maintain its good appearance. It is particularly essential that the carrier
slideway be clean and dry to prevent jamming. A soft cloth dampened in
warm, mild detergent solution will suffice.
2. If any surfaces have been contaminated with biohazardous material, a mild
sterilizing solution should be used. See Section 7.3 Decontamination
procedure.
Caution: DO NOT use any solutions containing hypochlorite, such as bleach, on
any of the stainless steel surfaces, as this may cause permanent damage
to the finish.
