Section 1: Introduction
1.1 Introduction
This following technical manual provides instruction on installation and operation of the Garnet
Removal System manufactured by Ebbco Inc. With correct maintenance and system operation the Garnet
Removal System will keep garnet form building up in the waterjet cutting machines work tank and will
increasing production by eliminating down time for tank shoveling. The Garnet Removal System will
require some assembly on site. This will include sweeper package assembly and connecting the Garnet
Removal System to the waterjet cutting machines work tank. The Garnet Removal System is
manufactured using quality materials and by highly experience production staff. The Garnet Removal
System is tested in Ebbco's test department to ensure that it meets the specifications required by the
customer. The Garnet Removal System is inspected and all test data documented prior to shipment.
1.2 Sequence of operation.
This system is designed to keep garnet from building up in the cutting table. The method used to
achieve this is the use of agitation on the bottom of the tank by water pumped through eductor header
nozzles located and directed in engineered locations. The garnet thus stays in suspension due to the
agitation and is carried out of the tank by way of the heavy duty centrifugal pump. It is pumped through a
centrifugal separator, which concentrates the garnet in the fluid stream and separates it for disposal into
an abrasive bag hopper. Excess water that comes out of the separator when it purges the solids from the
collection chamber is decanted from the hopper, returning to system tank.

Section 3: System Installation and Start-Up
3.1 Installation Procedure
1. Upon receipt of the system, carefully check each component against the bill of materials to ensure
that everything has been received with the system. If anything is missing or damaged, immediately
contact the freight company to file the appropriate claim.
2. Remove system from wooden 2 x 4 undercarriage using suitable materials handling equipment.
3. Install catcher tank sweeper package as shown in the sweeper layout drawing provided.
4. Install the gate valve to the suction port on the catcher tank.
5. Install the gate valve to the discharge port on the catcher tank.
6. Install hose barbs into the suction and discharge gate valves.
7. Close the suction and discharge valves.
8. Fill the catcher tank with water.
9. Position system next to waterjet machine as discussed with Ebbco Inc. Anchor system to floor as
necessary.
10. Using the black suction hose and clamps provided in the installation kit, connect the suction barb on
the catcher tank to the suction barb on the garnet removal system.
11. Using the black discharge hose and clamps provided in the installation kit, connect the discharge
barb on the catcher tank to the discharge barb on the garnet removal system.
12. Place abrasive bag hopper under purge outlet. Connect decant line to fitting provided on hopper.
13. Connect the overflow piping from the 3" port on the abrasive bag hopper to the garnet pump column.
14. Have a qualified industrial electrician connect the 3 phase electrical power to the control panel as per
electrical drawing. (230vac/3 ph/60Hz)
3.2 Start Up Procedure:
1. Check the pump suction basket for debris.
2. Open the suction and discharge valves on the catcher tank.
3. Ensure that the catcher tank is full of water.
4. Check pump for correct rotation (clockwise as viewed from the top of the motor) by bumping the HOA
switch, located on the main electrical panel.
5. The pump motor on the filtration system has been synchronized at the factory if the pump motor is
running in reverse have a qualified electrician swap over one of the in coming line powers at electrical
panel.
6. Turn the HOA switch to the HAND position.
Warning! If the filtration system dose not prime after 5 seconds, stop the system. Try three more times
and if the system still will not prime call the Ebbco service department 1-586-716-5151
7. Check separator inlet and outlet pressure gauges to ensure differential pressure is between 4 and 12
psi.

Section 4: System Maintenance
4.1 Garnet Removal System Daily Check List
Warning Always disconnect power and relive pressure from the system before performing any
maintenance on this filtration system.
Caution Always follow correct lock out procedures when working on this filtration system.
Warning Failure to keep suction above −10 in/hg could result in catastrophic pump failure.
1. Make sure suction basket is serviced (empty).
2. Open all gate valves.
3. Start filtration system.
4. Check suction basket pressure gauge. At start up this should read approximately −3 in.hg – service
basket before the suction vacuum gauge reads −10 in.hg.
5. Check inlet and outlet gauges on top of separator. These pressure readings should be approximately
35 psi on the inlet gauge and approximately 26 psi on the outlet gauge. Separator must run between
4 and 12 psid.
Warning This garnet removal separator must run between these pressure differentials. If the system does
not maintain the proper differential pressure it will affect the garnet removals performance and can cause
premature pump maintenance/failure.
6. Service hopper as needed.
7. In front of the eductors there will be no garnet accumulation, however there maybe some quite areas
in the tank where garnet may collect. The garnet "pile" should not be allowed to exceed 6" in height.
Monthly checking of garnet build up on the tank bottom is advised, using a stick tap on the tank
bottom in various locations. Any garnet accumulation will show up on the stick and it can be easily
removed.
If there are any questionsregarding this system please call the Ebbco Service Department at
1-800-991-4225

Section 4: System Maintenance
The system will require the following items to be maintained on a scheduled basis.
Warning Always disconnect power and relive pressure from the system before performing any
maintenance on this filtration system.
Caution Always follow correct lock out procedures when working on this filtration system.
4.2 Pump Suction Basket
The vacuum gauge located on the pump suction basket should be monitored every time the system is
started and then after every 8 hours of operation to ensure that the suction does not exceed −10 in/hg.
The pump suction basket should be removed and emptied every 8 hours of operation. It is important to
check the condition of the gasket on basket’s lid, make sure it is free of dirt and is firmly in place before
turning the system back on.
Ebbco recommends that a preventive maintenance schedule be implemented for this component.
Note: The vacuum gauge must read −3 in.hg – service basket at −10 in.hg.
4.3 System Pump
The centrifugal pump has been tested and greased at the factory; therefore lubrication is not necessary
for a period of approximately six to eight months. Remember that over greasing will cause the bearing to
run hot, so grease bearings sparingly when it is necessary. Ebbco recommends the use of sri # 2
chevron ball bearing grease.
Applications were there is a high abrasion the pump may have to be inspected quarterly for wear on
impeller and impeller housing.
It is recommended that a routine maintenance schedule be set up and followed for the best service of the
pump. A periodic comparison of existing operating conditions and data against data taken when pump
was initially started may indicate a problem developing and allow for a planned maintenance check before
a breakdown occurs.
4.4 Centrifugal Separator
There is no scheduled maintenance on the separator itself.

Section 4: System Maintenance
4.5 Work Tank Sweeper Package
To ensure that the garnet removal system works
at the designed performance the work tank
sweeper package must be visually inspected
every 12 months. If the sweeper package is
damaged (broken eductor or piping, blocked
suction) there will be a noticeable change in
system performance. This may manifest itself as
a separator inlet pressure drop, a low differential
across the separator or a high vacuum gauge
reading. If any of these condition occur and are
not corrected the system pump and other
components will become damaged.
Once the work tank has drained of water:
•Check for damaged of broken piping and eductors.
•Check for any garnet build up in front of any eductor.
•Check for any material that may be wedged between the eductor nozzle and the horn.
Ebbco Inc can provide an experience service technician to service the tank sweeper package and inspect
the complete system. Please call Ebbco for pricing and to schedule a service technician.
4.6 Abrasive bag hopper
The hopper should be visually inspected to be aware of solids level, service when full.
