Start and Stop Operation:
The X-Caliber will soft-start when the pressure drops to the pre-set cut in pressure or when it detects a high flow
condition. A high flow condition is defined as a drop in pressure of 1.4 psi/sec (.1 bar/sec). It will soft stop when it
has reached its maximum pressure.
The power setting, and the friction and lift loss of the supply piping will determine the maximum shut off pressure of
the pump. The pump will vary its RPM to maximize its performance while maintaining constant input power.
Pressure Boosting Applications:
The X-Caliber can be used in pressure boosting applications. If supplying the inlet of the pump with pressurized
water, ensure that the sum of the inlet pressure and the max pressure capable of the pump does not exceed the
rated pressure of the piping system.
For example; a 30 psi (2 bar) inlet pr 53 psi (3.6 bar) pump pressure = 83 psi (5.6 bar) max pressure
generated.
Headhunter recommends the installation of a high flow Headhunter # PR-750 pressure regulator on the inlet supply
of the pump so that the maximum pressure generated can be safely adjusted.
Status Indication:
To determine what settings have been programmed into the pump, push the hidden mode switch momentarily (<8
seconds).
