It is recommended that the following maintenance actions are performed annually or every 2,000 working hours.
Operating arm
1. Check the state and tension of the belt.
2. Replace the elements in an unsatisfactory state.
3. Make the adjustments and tests related to the service program.
Dispensing system.
1. Exhaustively wash all the dispensing circuit with washing solution and rinse it with distilled water.
2. Remove and clean the needle. Check its state.
3. Check the state of all the dispensing circuit tubes. Check the absence of obstructions or diameter changes.
4. Check the leakproof quality of the nuts and the 3-channel electrovalve body.
5. Check the leakproof quality of the dispensing pump nut and seal. Check there is no loss and no bubbles. Change
the seal every 2 years.
6. Clean the distilled water container lters.
7. Clean the washing station.
8. Check the state of the washing system tubes.
9. Replace the elements in an unsatisfactory state.
10. Make the adjustments and tests related to the service program.
Reactions rotor
1. Check the state of the heating canal.
2. Verify the gap betwen gears.
3. Replace the elements in an unsatisfactory state.
4. Make the adjustments and tests related to the service program.
Optical system
1. Check the state of the lamp. Check if it has been working for over 1,000 hours.
2. Clean the lters.
3. Clean the photodiode.
4. Replace the elements in an unsatisfactory state.
5. Make the adjustments and tests related to the service program.
5.3. CARE AND CLEANING
5.3.1. General care of the analyzer
a) Never use detergents or abrasive products for cleaning the surface of the analyzer. Use only a damp cloth with
water and pH-neutral soap.
b) If a reagent or corrosive product spills or splashes onto the apparatus, clean it with a damp cloth and soap imme-
diately. If necessary, protect your hands with appropriate laboratory gloves.
c) All the elements of the analyzer have drainage conduits leading to the exterior to enable the elimination of any
liquid spilled and to prevent the apparatus from ooding. If the spillage is signicant, the liquid spilled onto the table
through the drainage conduits and the analyzer must be adequately cleaned.
d) When not in use, close the main cover of the analyzer to protect it from dust.
5.3.2. Cleaning the optical system
The components of the optical system must be cleaned periodically in order to keep them free from dust and dirt.
These components are the lamp, the lters and the photodiode. The recommended necessary material is as follows:
- Special paper for cleaning optical components (non-abrasive paper which does not leave solid residue).
- Ether and alcohol solution at 50%
- Cotton wool buds.
- Small bellows.
All the optical elements must be handled in an area of maximum cleanliness, given that they are fragile and delicate.
