Maintenance
DANGER
Débranchez toujours l'alimentation de l'analyseur d'echantillonneur avant de
procéder à un entretien ou une réparation.
Clean the interior and exterior of the sampler cabinet with a damp sponge and
mild detergent. Do not use abrasive cleaners.
Clean the bottles using a brush and water with a mild detergent, followed by a
fresh water rinse and a distilled water rinse. Glass bottles may also be
autoclaved.
Clean the tubing by pumping water with mild detergent or other cleaning
solution through the tubing, using the peristaltic pump in Manual Pump Mode.

MANUAL MODE
The sampler does not require routine lubrication. Do not lubricate the pump
tube with petroleum jelly, silicone grease, oil, or any other lubricant, as this will
substantially reduce the life of the pump tube and roller assembly.
DANGER
Débranchez toujours l'alimentation de l'analyseur d'echantillonneur avant de
déposer le couvercle de la pompe.
Replacement pump tubing is available from the manufacturer in 15' bulk
length (Cat. No. 4600-15), and 50' bulk length (Cat. No. 4600-50). Use of
tubing other than that supplied by the manufacturer may cause excessive
wear on mechanical parts and/or poor pump performance.
Pump tubing life depends on several factors:
• Distance from sample source. Locate the sampler as close to the sample
source as possible.
• Vertical lift. Minimize the vertical lift (ideally, 15 feet or less).
• Intake Rinses. Minimize the number of intake rinses prior to
sample collection.
• Pump roller assembly condition. Remove (clean) the silicone residue in
the interior of the pump housing and on the rollers before installing a
new tube.
• Constituents in the sample liquid. Grit and other abrasive solids
cause greater wear on the tubing as they are squeezed through the
pump rollers.
