Tighten a new ferrule 1¼ turns the first time it is tightened. Then, only tighten the ferrule 1/8 turn to make a
connection. Do not tighten the fittings more as this may cause damage to the fittings or ferrules and cause leaks.
If a leak occurs in the tubing, the sample water will drain from small holes in the bottom of the
enclosure.
For leaks caused by a valve, worn tubes or other parts, send the instrument to the manufacturer for
service. Refer to Send the instrument for service on page 42
