Cleaning
Under no circumstance should the Sentinel modules or ECU be cleaned with a pressure
washer. While the flow modules and ECU are sealed, the intense pressure generated by
pressure washers may penetrate the seals and cause irreversible damage.
Winterization
If injecting a nitrogen stabilizer, SurePoint recommends flushing your system by running at least one tank of
NH3 without the nitrogen stabilizer to clean the system out.
Pre-season Service
(A little time spent here may prevent some downtime when you want to be rolling.)
1. Visually check entire system (hoses, fittings, harnesses, etc.) for any signs of wear or trouble.
2. On the display, recheck all setup screens (see Section D) to verify correct setup.
3. Tighten all clamps. Loose clamps may be evident by leaks on the output side of the system.
