Cleaning the Splash Guard/Safety Shields
The Splash Guard/Safety Shields must be cleaned weekly.
1. Turn off the power to the Autosampler.
2. With a lint-free cloth, wipe the splashguards thoroughly.
Cleaning the Lead Screw and Lead Screw Encoder
If the pump is used in a dusty environment, the lead screw encoder should be cleaned
periodically with air. The lead screw should be lubricated:
• If the pump is making a "screeching" noise
•
If the syringe is stalling frequently
NOTE: Only PerkinElmer lubricant (part number L1200559) should be used for lubricating
the lead screw. Lubrication is usually only needed after 1 million syringe strokes (or
every 6 months). If the pump appears to need lubrication more frequently, suspect
another problem.
Cleaning X-Y-Z Mechanism
The X-Y-Z mechanism should be cleaned every six months. However, if the instrument is
operated in a dusty or humid environment, it must be cleaned every three months. Follow
the instructions to prevent damage to the instrument.
1. Turn off the power to the Autosampler.
2. Clean the Z-Rack.
3. Clean the needle.
4. Wipe the arm using a lint-free cloth dampened with isopropyl alcohol to remove any
residual dust.
5. Wipe the inside of the flex cable channel using a lint-free cloth dampened with isopropyl
alcohol.
CAUTION
Use only isopropyl alcohol and a lint-free cloth to clean the Autosampler.
Other cleaning agents may affect the performance of the instrument.
Never clean the X-Y-Z axis guide rails or Z-Rack with alcohol or solvent.
Serious damage to the instrument may occur.
CAUTION
Do not wipe the X-axis guide rails. The guide rails are lubricated with a
grease that does not require removal unless found to be "extremely"
dirty.
