Operating the CaviBlaster
TM
system:
1. When the diver is ready to commence cleaning operations, ensure that the Zero Thrust Gun is
submerged in water. If the diver is not wearing a helmet, hearing protection is
recommended. Cavidyne recommends “Doc’s Proplugs” vented earplugs for diver hearing
protection.
2. Activate the cleaning cavitation stream by squeezing the trigger to the open or “ON” position
(Figure 9).
3.
The most efficient operating technique is to hold the Zero Thrust Gun 2-3 inches (5-8 cm)
away from the surface to be cleaned and at a 25 to 45 degree angle to the surface being
cleaned (Figure 9).
Placing the Zero Thrust Gun closer than 2-3 inches from the surface
being cleaned will not allow for efficient cavitation performance and will degrade the
cleaning capability of the system.
4.
Wear neoprene or rubber gloves to protect the hands and follow all safety regulations that
may be applicable to the work being performed.
5. If the diver operating the unit must be replaced or the cleaning operation must be interrupted
for a prolonged period or terminated, shut down the motor by depressing the red “STOP”
button (Figure 8) on the motor controller. Turn off the water supply to the pump,
and then
release the water pressure in the hose(s) by squeezing the Zero Thrust Gun trigger to the open
or “ON” position (Figure 9)
while under water
.
Revert back to step 1 of the operating
instructions when the replacement diver is ready to continue cleaning.
6.
Ensure that the Zero Thrust Gun is submerged any time the motor and pressure pump are
operating.
Adjusting the CaviBlaster
TM
system for maximum performance:
1.
If using a calibration pressure gauge situated between the pressure hose and the CaviBlaster
TM
Zero Thrust Gun, the water pressure should be 2,200-psi with the Zero Thrust Gun
submerged and the Zero Thrust Gun trigger in the open or “ON” position.
The pressure is
adjusted by turning the nuts on the end of the pressure-regulating unloader (Figure 5) to
compress or relax the green spring.
This adjustment increases or decreases the flow of water
through the bypass hose when the CaviBlaster
TM
Zero Thrust Gun trigger is in the open or
“on” position. The flow of water through the bypass hose, in turn, determines the flow of
water through the pressure hose and the Zero Thrust Gun. Less flow through the bypass hose
means more flow through the Zero Thrust Gun which translates to higher velocity and
pressure.
Turn the nuts to compress the spring to decrease the amount of water passing
through the bypass and increase the water flow and pressure at the Zero Thrust Gun. Turn
the nuts to relax the spring to increase the amount of water passing through the bypass and
decrease the water flow and pressure at the Zero Thrust Gun.
There should always be a
trickle of water through the bypass when the Zero Thrust Gun trigger is in the open or “ON”
position.
This ensures that the bypass will open without a pressure shock wave damaging the
pump when the Zero Thrust Gun trigger is released to the closed position.
