Section 4.0 Installation
4.1 The cabinet should be placed on a flat, level surface, and positioned considering space
for loading/unloading access, as well as on going servicing and maintenance. It is
recommended that there should be 1200mm clear area on both the work door side of
the cabinet, and the rear of the cabinet.
4.2 Connect a 12.7mm (½”) air supply hose to the compressed air
connection point on the rear of the cabinet. Ensure that the
supply hose is correctly fitted and secured with a correctly sized
hose clamp.
4.3 Connect a 12.7mm (½”) water supply hose to the water
connection point of the rear of the cabinet. Ensure that the
supply hose is correctly fitted and secured with a correctly sized
hose clamp.
4.4 An overflow outlet is located on the cabinet lower hopper at
the rear if the cabinet. A water receptacle should be placed
underneath the overflow to trap any excess water as it flows
out.
WARNING –ALL ELECTRICAL AND PLUMBING
CONNECTIONS MUST BE CARRIED OUT BY SUITABLY
QUALIFIED AND EXPERIENCED TRADESPERSONS. ALL
CONNECTIONS MUST COMPLY WITH LOCAL SITE
REQUIREMENTS AND/OR REGULATIONS.

Section 5.0 System Operation
5.1 Check that the MultiBlast PRO900W cabinet has been correctly installed as per
Section 4.0 of this manual.
5.2 Turn on the main power supply.
5.3 Turn on the compressed air supply.
The input pressure gauge on the
control panel will display the
incoming air pressure.
5.4 Set the air pressure to the desired blasting pressure, by adjusting the pressure
regulator located on the control panel. Unlock the regulator by pulling the knob
outwards. Increase the pressure by rotating the knob clockwise, and decrease the
pressure by rotating the knob anti-
clockwise. The set pressure will be
displayed on the work pressure
gauge in the control panel
5.5 Turn on the cabinet internal work
light using the switch located in the
control panel

pressure gauge
NOTE –The blasting air pressure will vary depending
on the individual operating conditions and the desired
end result. The recommended air pressure for most
applications is between 0.35Mpa (50psi) and 0.55Mpa
(80psi) –DO NOT EXCEED 0.68Mpa (100psi)

5.6 Turn on the water inlet valve located on the rear of the
cabinet, allowing approximately 25 litres of water to flow
into the cabinet hopper, then turn of the water inlet valve.
Discharge of water from the cabinet overflow indicates that
the water level is correct.
5.7 Unlatch and open the cabinet door, and load approximately 5-6kg of abrasive media
(normally glass beads) into the cabinet hopper through the cabinet mesh floor.
5.8 Depressing the foot switch will now start both the air and water supply to the blast
gun.
5.9 Load the component to be blasted into the cabinet through the door opening, place
it on the cabinet mesh floor, close the door and latch it shut using the two door
latches.
Water Inlet Valve
NOTE –If the system has just been filled, or has been
idle for some time (say overnight) it is recommended
that the water and air system be cycled for several
minutes to ensure the abrasive and water are
thoroughly mixed together before blasting operations
commence.
Note –The cabinet is fitted with a
safety door interlock which will
prevent the system from operating
with the door open.

5.10 The operator now places their hands into the cabinet gloves, grasps the blast gun and
then depresses the foot switch. Blasting operation will now commence.
5.11 The operator now moves the blast gun across the surface of the component until the
desired surface finish is achieved.
5.12 The stop blasting, release the foot switch and both the compressed air supply and
water pump will cease operating.
5.13 Periodically, during operation it will be necessary to operate the window wiper in
order to clear the operator window. The window wiper may be operated either
manually or automatically.
5.14 To operate the window wiper automatically, rotate the flow control valve located of
the window wiper drive assembly. Rotating the control know clockwise will slow the
wiper speed, while rotating the control knob anti-clockwise will increase the wiper
speed.
5.15 To operate the wiper manually, rotate the lever located on the wiper drive assembly
through an arc left to right.

the window be rinsed with clean water from the wash
down gun prior to operating the window wiper.

5.16 It will be necessary to periodically check the abrasive to water mix ratio, which should
normally be 10-15% abrasive to water. To check the ratio, follow this procedure –
5.16.1 Place a small bucket or similar container inside the cabinet, close the door,
and blast into the container until you have collected approximately 1 litre of
water and abrasive mix.
5.16.2 Pour 500ml of the container contents into a 1 litre graduated flask, and leave
to stand for several minutes to allow the abrasive in the water to settle.
5.16.3 Check the level of the settled abrasive in the bottom of the flask. If the ratio is
correct, the abrasive level should read between 50ml and 75ml (10% to 15%
of 500ml)
5.17 Also over a period of time, the abrasive in the water will breakdown, reducing blasting
efficiency. At this time, it will be necessary to drain the cabinet completely and refill
with it with clean water and new abrasive media.
5.18 To drain the cabinet, place a suitable sized container beneath the drain valve located
on the rear of the cabinet pump hopper. Open the drain valve, and allow the system
to drain out.
5.19 Abrasive will have settled in the bottom of the
hopper, so use the wash down gun to wash down
the inside of the cabinet and flush out the pump
hopper.
5.20 Once fully drain and cleaned, refill the system with water and abrasive media as per
Section 5.6 and 5.7.

Section 6.0 Maintenance
6.1 On a daily basis –
6.1.1 Inspect the door seal and replace if damaged or worn
6.1.2 Inspect the operator gloves for wear, holes and/or cuts. Replace if necessary.
6.1.3 Check the condition of the operator viewing window, and replace if the
operators view is obstructed due to wear/scratches.
6.1.4 Check that the door safety interlock is working correctly, and that the system
will not operate with the door open.
6.2 On a monthly basis –
6.2.1 Dismantle and inspect the blast gun assembly. Check the blast nozzle inside
diameter for wear, grooves or cracks, and replace if required.
6.2.2 Check the blast nozzle inside diameter. Replace the nozzle if it has worn more
than 1.5mm from its’ original size. Use a 6mm diameter drill to check the
nozzle for size.
6.2.3 Check the air tip for wear and grooves. Replace the air tip if it has worn more
than 3mm from its’ original size.
6.2.4 Feel along the length of the blast hose between the blast gun and the water
pump. Check for any soft spots which will indicate hose wear. Replace the
hose length as necessary.
