Installation
Install the external boost pump (optional)
An external boost pump is optional for HyPrecision P-15/P-30/P-50 pumps.
A boost pump increases the supply water pressure to 7.6 bar (760 kPa / 110 psi). A sustained pressure of lower
than 2.8 bar (280 kPa / 40 psi) or meeting the maximum set pressure of 8 bar (800 kPa / 115 psi) causes the
pump to turn off.
The boost pump assembly includes a pump, a 1-way check valve, and a bypass relief valve. The relief valve
prevents overpressure in the low-pressure water system.
Parts, tools, and materials
The 15-foot water hose has a 1/2-inch fitting.
1. Locate the wiring access hole in the bottom of the electrical enclosure.
2. Remove the wing nut holding the hole plug.
Keep the plug and wing nut to use if the pump is stored or shipped.
3. Put the cord grip connector on the cord.
4. Put the cord and the threaded end of the cord grip connector through the hole.
