5.4 Adjusting the CaviBlaster for Maximum Performance
The pressure at the nozzle of the zero-thrust gun has to be maintained within
certain limits to achieve cavitation and for best performance results. Using a
calibration pressure gauge tool situated between the pressure hose and the
CaviBlaster zero-thrust gun, (See Figure 5.2) the water pressure should be 2,800
psi (190 BAR) with the gun submerged and the gun trigger in the open or “ON”
position. For best results, repeat this calibration procedure if cleaning
performance degrades, or every 3 months at a minimum.
To calibrate the pressure at the zero-thrust gun, follow the procedure below:
-
Stop the power unit and pull the gun trigger to discharge any residual
pressure in the hose lines.
-
Disconnect the gun with its whip hose from the main pressure hose line.
-
Attach the calibration gauge to the main pressure hose line and attach the
whip hose to the pressure gage. Tighten the JIC connections.
-
Submerge the gun because of the danger of the operator coming in contact
with either of the water streams from the cavitating or zero-thrust nozzles,
Cavidyne does NOT recommend calibrating the gun out of the water. Use
extra care to avoid both water streams if doing so.
-
Ensure that both the cavitation and zero-thrust nozzles are pointed away from
the diver’s or operator’s hands, arms and body.
-
Start the power unit (See Section 5.2).
-
Pull the gun trigger to the open or “ON” position (See Figure 5.3).
-
Hold the gun tight and observe the calibration gauge (See Figure 5.2).
-
The power unit operator should turn the knob on top of the pressure
regulating valve until pressure reads 2,800 psi (190 BAR) on the calibration
gauge at the Z/T Gun. Turning the knob clockwise will increase the pressure
and turning it counter clockwise will decrease the pressure.

A calibration gauge is recommended with every unit.
Connect between the main pressure hose and the whip
hose or gun. See figure 5.2.
Do not adjust the pressure at the gun to more than 2,800-psi
(190bar). Higher pressure will not improve peformance.
