maintenance or service.

 

7.1 Cleaning the Sampler

7.1.1 Cleaning the Sampler Cabinet

Clean the interior and exterior of the sampler cabinet with a damp sponge and mild detergent. Do not use abrasive cleaners.

7.1.2 Cleaning the Sample Bottles

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.

7.1.3 Cleaning the Intake Tubing and Pump Tubing

Clean the tubing by pumping water with mild detergent or other cleaning solution through the tubing, using the peristaltic pump in Manual Pump Mode. Press MANUAL MODE.

7.1.4 No Lubrication Required

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.

7.2 Pump Tubing Maintenance

pump cover.

 

 

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.

7.2.1 Tubing Life Estimates

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.
