To calibrate the pressure at the CaviBlaster
®
power unit, the water pressure at
the power unit will need to be higher to account for sidewall friction loss in the
pressure hose. The pressure at the pump should be 3,700-psi (255 Bar) plus 0.5-
psi per foot (0.11 Bar per meter) of pressure hose. For example, if using the
CaviBlaster
®
with 100 feet (30 meters) of pressure hose, the pressure gauge
located next to the pump should indicate 3,750-psi (258 Bar). Pressure
adjustments are made by turning the knob on top of the pressure regulating valve
in the same manner as described above.
Figure 5.2
– Pressure Regulating Valve
DO NOT ADJUST THE PRESSURE AT THE GUN TO MORE
THAN 3,700-PSI (255 Bar). HIGHER PRESSURE WILL NOT
IMPROVE PEFORMANCE.
HOSES ARE RATED FOR MAXIMUM 5,000-PSI (345 Bar).
PRESSURES ABOVE 5,000-PSI COULD RESULT IN HOSE
FAILURE.
