GENERAL DESCRIPTION
The CaviBlaster® 1325-D high-pressure water power unit allows the operator to use the
water flow and pressure to generate cavitation at the end of the proprietary nozzle.
The CaviBlaster® cleans the surface of any underwater structure using the energy
released by the implosion of the cavitation bubbles during the cavitation process. When
directed at the surface being cleaned, the energy released by the collapsing cavitation
bubbles causes marine growth to be removed from the surface.
The system consists of a portable, zero-thrust gun, connecting high-pressure hose and
a diesel-powered, high-pressure pumping unit. The zero-thrust gun uses a trigger
operated valve to control the water stream off and on. If the valve is closed, the power
unit goes into bypass mode unloading the engine and the pump.

The CaviBlaster® 1325-D power unit is a complete “plug and play” system built into a
self- supporting frame that allows quick deployment and/or installation of the unit. Water
can be supplied from either a pressurized source, directly from the natural source via an
electric booster pump supplied with the power unit), or from a gravity feed storage tank.
The unit is equipped with many features to maintain operator safety while operating at
pressures of 2,500 psi 172 BAR).

SAFETY INFORMATION
The CaviBlaster® 1325-D power unit is an inherently powerful and potentially dangerous
piece of equipment; however, with proper care and training it can be operated safely.
The 1325-D must only be operated by personnel that have read and understand this
manual. It is intended to reinforce and review safety techniques to prevent personal
injuries and property damage.
Users must comply with all local, state, and national laws concerning high-pressure
water jetting equipment as well as all underwater work regulations.
It is strongly recommended that this entire manual be reviewed in-depth before
operating or servicing this equipment. Service work should only be performed by
individuals who are proficient in using and maintaining this equipment. Refer to the
applicable section in this manual for the correct procedures prior to any installation,
setup, or maintenance work.
Personal Safet
Operation of the CaviBlaster® 1325-D underwater cleaning system must only be
attempted by commercial divers or other personnel who have been trained in its use.
Appropriate protective equipment should always be worn. Operation of the system
without the proper equipment and training can result in personal injury.
CaviDyne LLC is not responsible for damages resulting from a
failure to comply with instructions in this manual. Please read
carefully before use.
If maintenance or repair of the CaviBlaster un is bein
conducted out of the water, remember that the zero- thrust
un has front and rear jets. Never direct the jet streams at
a person or animal. Never direct the jet streams toward
power lines or other hi h volta e
equipment.

Ensure that there is a safe area to work while operatin
the CaviBlaster® 1325-D.
Seek immediate medical attention if the operator suffers
an injury as the result of contact with the hi h-pressure
water stream. Serious personal injury can result from
an untreated water injection wound.
Personal Protective Equipment (PPE)
Always wear appropriate Personal Protective Equipment PPE) when operating this
equipment.
Personnel operating or working in the vicinity of the power unit should wear appropriate
hearing protection when the CaviBlaster® system is in use. If the diver is not wearing a
diving helmet, hearing protection is recommended. CaviDyneTM suggest wearing vented
earplugs, such as “Doc’s Proplugs”, for diver hearing protection.
The operators of the CaviBlaster® system should always wear neoprene or heavy
rubber gloves to provide protection to the hands and, in particular, to the fingernails. The
gloves will absorb most of the energy produced by bursting cavitation bubbles and
prevent the cavitation bubbles from contacting the operators’ hands. The gloves will also
protect operators’ hands from the initial shockwave when the gun is activated.
Failure to wear appropriate PPE may result in personal injury.

INSTALLATION
The CaviBlaster® 1325-D must be installed in accordance with the requirements outlined
below. The unit can be installed in a vehicle to allow for maximum mobility and flexibility.
Uncrating and Lifting
Unpack the equipment and inspect for damage. If damage is found, immediately contact
CaviDyneTM and the shipping company. If the unit will not be installed immediately,
provide adequate indoor storage to protect against damage.
The CaviBlaster® power unit is designed to work with forklifts and also can be lifted with
the lifting eyes provided on top of the frame. Verify that lifting equipment is rated for the
weight listed in Section 1.0 UNIT SPECIFICATIONS and that the unit is stable before
lifting.
Figure 4.1 – Lifting Guidelines
Page - 13
CaviBlaster 1325-D Operations Manual
For More information please email [e-mail] or call 1- 352)275-5319

Installation Location
For maximum flexibility the CaviBlaster® power unit should be installed in an area where
it is capable of reaching both its water source 6ft 2 Mts) max lift) and anticipated
cleaning targets within acceptable hose lengths 328ft 100M) max). The CaviBlaster®
power unit can be installed in an enclosed* or open environment.
* Enclosed installations will require provisions for adequate engine cooling air
flow and for venting of engine exhaust. See Figure 4.2 below.
Installation location must be a level surface able to safely support the unit weight listed
in Section 1.0 UNIT SPECIFICATIONS. Orient unit to allow unrestricted access to the
hose connection plate and control panel, located on the front of the unit. Allow a
minimum of three feet around the unit and access from above to conduct service and
repair work. Take note of frequently serviced areas such as the engine, belts and fuel
tank.

Connecting the Water Source
The CaviBlaster® power unit can be used with seawater or fresh water.
However the unit must be flushed with fresh water minimum of 1-2 minutes) after each use
in seawater to ensure good service and long life.
The aviBlaster® 1325-D must be flushed and rinsed
with fresh water after every use in seawater.
Failure to flush and rinse the power unit after use in
seawater will result in increased wear and tear on
components and in decreased service life.
Failure to flush and rinse the unit can cause the pump
valve(s) to stick in the open position. This will prevent
the system from producing the correct operating
pressure.
The feed water inlet connection is located on the control panel See Figure 2.2). An electric
submersible water pump is supplied to provide positive inlet water pressure to the main
pressure pump.
Two water supply conditions are acceptable for the CaviBlaster® power unit.
a) Forced inlet water condition using the supplied electric water pump OR an outside
water source capable of supplying a minimum of 150% of the main pressure pump
flow rating 20 GPM /76 LPM) at a maximum pressure of 50 PSI 3.5 BAR)

b) Gravity feeding water source See Figure 4.4). In this case, the electric feed pump
is not required. Use a hose with a diameter of at least 1-1/4” to connect the water
tank to the power unit
