Note
Systems MUST be designed by qualifi ed technicians only and meet all applicable state and local
code requirements.
The following diagrams show a typical system using the AquaBoost Controller. 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.
A diaphragm pressure tank is used on the discharge side of the pump to maintain pressure in the line when
there is no demand. This will keep the pump from continuing to run. With the AquaBoost Controller, it is not
necessary to have a large tank for supply purposes. In selecting a tank, make sure it can withstand system pres-
sure. The tank should have a capacity of at least 10% of the maximum pump fl ow rate in gpm. Typically, pumps
used with the AquaBoost controller use a V6P or larger Goulds Pumps Hydro-Pro
®
Tank. Pre-charge the tank to
the following:
