LEAK DETECT
page 1 of 3
The S Series pump includes a highly sensitive leak detector. The detector can differentiate between a
tube rupture leak and water intrusion. The sensitivity feature reduces the number of false “tube leak”
signals due to the pump’s location in a wet environment, outdoors or if subject to hose down cleaning.
TO BE INSTALLED AND MAINTAINED BY PROPERLY TRAINED PROFESSIONAL INSTALLER ONLY.
READ MANUAL & LABELS FOR ALL SAFETY INFORMATION & INSTRUCTIONS.
Turn off water system, disable all pumps and depressurize the system before performing installation.
Always wear proper protective safety equipment when working with metering pumps.
• Field calibration of the pump in the application assures the “tube leak” signal represents the application’s chemical
and concentration.
• Refer to Configuration Menu section in the pump manual to select, fine-tune and program the responses available
when a “tube leak” signal is received.
• The leak detect sensitivity is factory pre-set to distinguish between water and typical water treatment chemicals.
Adjust the sensitivity according to the specific chemical utilized in the application. Adjust with the potentiometer
located under the signal cover, see below.
• When using external leak detect probes (not included with pump), connect to Leak Detect External, positions #16 and
#17 on the bottom row of the terminal on rear of the pump. The probes can monitor leakage in areas other than the
pump head. The probes should be constructed of Hastelloy
®
to inhibit corrosion.
NOTE: The leak detect function has one sensitivity adjustment. When external probes are used, confirm the sensitivity
setting is acceptable for the probes and liquid end.
