3: SYSTEM DESIGN
NOTE: Systems MUST be designed by qualified technicians only and meet all applicable state and local code
requirements.
The following diagrams show a typical system using the Aquavar ABII Constant Pressure System. Connection can be
made directly to a water supply or water can be drawn from a supply tank. Diagram #1 shows a typical set up for a
supply tank.
Diagram #2 shows a set-up for municipal water connection. This allows pump maintenance without main line shut-off.
