LCA
14.3 WATER PUMPING AND STORAGE SYSTEMS
LCA units may be equipped with 4 types of pumping systems, complete with expansion tank, and inertial
storage reservoirs:
- single standard pump
- single uprated pump
- standard pump and back-up pump
- uprated pump and back-up pump.
In the case of pump systems including a back-up pump, the microprocessor controls the pumps in such a
way as to equally divide the hours of operation, changing over the pumps in the event of a fault.
