This pump is equipped with a Tube Failure Detecting System which is designed to stop the
pump and provide an output alarm (see Output menu) in the event pump the tube should
rupture and chemical enters the pump head.
This patented system is capable of detecting the presence of a large number of chemicals
including Sodium Hypochlorite (Chlorine), Hydrochloric (muriatic) Acid, Sodium Hydroxide,
and many others. The system will not be triggered by water (rain, condensation, etc.) or sili-
cone oil (roller and tubing lubricant).

1. Remove the pump head cover, and the
pump tube and roller assembly.
2. Check for fluids at the bottom of the
pump head.

pump head. Ensure to remove all the
chemical traces from the sensor
