1.2 ! WARNING ! READ THIS SECTION
CAREFULLY BEFORE USING THIS EQUIPMENT
1.2.1 Heavy metal paint, asbestos and other toxic
material dusts will cause serious lung disease
or death without the use of properly designed
and approved air supplied respiratory (SAR)
equipment by blast operators and all personnel
within the work site area.
1.2.2 The compressor must have adequate output
and the plumbing between the compressor and
the point of attaching the air supply hose must
have sufficient capacity to supply the volume of
air at the pressure required.
1.3 Standard Safety Precautions
1.3.1 Approved safety eyewear, hearing and footwear
protection should be worn at all times by the
operator and anyone else in the immediate area
that may be exposed to any hazards generated
by the abrasive blasting process.
1.3.2 Suitably approved respiratory protection (PPE)
should also be worn when handling abrasive
media, abrasive refuse dust and when carrying
out any service/maintenance work where any
dust may be present.
1.3.3 Any work performed on any electrical wiring or
components must only be carried out by
suitably qualified and registered electrical
personnel.
1.3.4 Under no circumstances should any safety
interlocks / lockouts or features be altered or
disabled in any way.
1.3.5 All equipment must be isolated from the
compressed air supply and electrical power
prior to any service or maintenance work being
carried out.
1.3.6 All care must be taken by the operator(s) when
lifting or moving equipment or components in
order to prevent injury. Blast pots must always
be emptied of abrasive media before any
attempt is made to move them.
1.3.7 Any modification of the equipment or use of
non genuine PanBlast™ replacement parts will
void warranty.
1.3.8 Always check the Material Data Sheet (MSDS) on
the abrasive media being used to ensure that it
is free of harmful substances, in particular, free
silica, cyanide, arsenic or lead.
1.3.9 Test the surface to be blasted for harmful
substances, taking the appropriate measures to
ensure the safety of all personnel.
1.3.10 The operator should carry out a daily inspection
of all related components prior to startup of all
wearing and safety items to ensure they are in
correct operating order.
In particular check all Hose Couplings and
Nozzle Holders, ensuring that all Hose
Couplings are fitted correctly, the Safety Pins
are engaged and in good order. Always install
Safety Whip Check Cables at every hose
connection. Ensure that the Blast Nozzle has
been securely screwed into the Nozzle Holder
and the Nozzle Holder has been secured to the
Blast Hose correctly and all screws are engaged.
2.0 INTRODUCTION
2.1 Scope. These instructions cover the installation,
operation and maintenance of the PanBlast™
Junior Plana NPT Valve.
2.2 Application. The PanBlast™ Junior Plana NPT
Valve is designed to suit a multitude of abrasive
media from mineral abrasives such as Garnet to
metallic abrasives such as Steel Grit.
3.0 INSTALLATION
3.1 Depressurize and disconnect the air supply
from the blast machine and drain the abrasive
media from the Blast Pot ensuring that all
threads are clean of abrasive.
3.2 Disconnect the lower Pusher Line hose at the
existing abrasive metering valve. Remove the
existing abrasive valve including pipe fittings
and inspect the condition of the rubber hose
Pusher Line and replace if necessary.
3.3 Screw the Junior Plana Valve onto the existing
pipe nipple. Ensure that the threads are free of
abrasive and debris, use thread sealant to
ensure that an air tight joint is achieved.
3.4 Ensure that the valve arrangement is positioned
to allow unobstructed movement of the
metering adjustment handle.

3.5 Fit the Pusher Line hose barb fitting to the
supply air end of the lower “T” piece fitting
(client supply), use thread sealant to ensure an
air tight joint.
3.6 Push the Pusher Line hose onto the hose barb
fitting and tighten the two bolt hose clamp on
to the hose.
3.7 Fit the screwed hose coupling to the discharge
end of the lower “T” piece, use thread sealant to
ensure an air tight joint.
3.8 Refit the blast hose ensuring that the coupling
Safety Lock Pins are fitted.
4.0 OPERATING INSTRUCTIONS
4.1 The Junior Plana Valve is fully CLOSED when the
metering handle is positioned in a parallel line
to the abrasive inlet feed port, the fully OPEN
position can be obtained by moving the
metering handle either side of the parallel
position.
4.2 To set the correct abrasive feed on the valve,
have a suitably experienced person assist in the
adjustment. Point the nozzle at a test piece,
deactivate the safety lock on the Deadman
Handle and depress the lever, have the person
assist in slowly moving the control handle from
the CLOSED position toward the OPEN position
in small incremental movements. Allow the
abrasive feed to stabilize at each position and
ascertain whether a correct blast mixture has
been achieved. The valve opening is correct
when the flow from the Blast Nozzle slightly
discolors when viewed from a light contrasting
background.
4.3 If no discoloration is evident and there is a high
pitched sound from the Blast Nozzle, the
abrasive media feed is too lean and the
abrasive media flow needs to be increased by
further opening the valve’s metering handle.
4.4 If the feed to the Blast Nozzle is erratic and
surging then the abrasive media feed is too rich
and the abrasive flow needs to be decreased.
5.0 MAINTENANCE
! WARNING ! THE COMPRESSED AIR
SOURCE MUST BE ISOLATED BEFORE
PERFORMING ANY MAINTENANCE WORK.
FAILING TO DO SO MAY CAUSE SERIOUS
INJURY OR DEATH.
5.1 Inspection of the Control Plate can be done with
the valve in place on the blast machine. Ensure
the blast machine has been completely
depressurized and that the compressed air
supply has been isolated. Remove the metering
handle from the Control Plate. Undo the 4 bolts
on the valve assembly which allows the lower
body assembly to drop away from the Upper
Body allowing easy inspection of the Control
Plate and replace if required.
5.2 With the lower body assembly removed inspect
the discharge nipple and “T” piece assembly for
wear and replace if required.
6.0 TROUBLE SHOOTING
6.1 No abrasive flow.
6.1.1 Damp abrasive. Depressurize the blast machine,
and remove the metering handle from the
Control Plate. Undo the 4 bolts on the valve
assembly which allows the lower body assembly
to drop away from the Upper Body allowing
easy inspection, clean and remove any damp
abrasive media and reassemble the valve.
6.1.2 Obstruction in valve. Depressurize the blast
machine and remove the metering handle from
the Control Plate. Undo the 4 bolts on the valve
assembly which allows the lower body assembly
to drop away from the Upper Body allowing
easy inspection, clean and remove any damp
abrasive media and reassemble the valve.
6.2 Irregular abrasive flow.
6.2.1 Incorrect adjustment of the abrasive media
valve may cause irregular abrasive flow, check
the metering plate setting as outlined in section
4.2.
6.2.2 A high degree of fines in the abrasive mix can
cause “Rat Holing” leading to erratic abrasive
feed, check the abrasive and replace if
necessary. Refer section 6.1.1 above.
6.2.3 Abrasive media is not free flowing; this will
require adjustment of the Pusher Line Ball Valve
to improve flow from the blast machine.
6.3 Air leakage at the Valve.
6.3.1 Check the body clamping bolts have been
tightened correctly.
6.3.2 Inspect the Upper Body O-Ring condition,
replace if worn.
6.4 No abrasive or air from nozzle.
6.4.1 Obstruction at the Blast Nozzle, depressurize
blast machine and remove the nozzle from the
Nozzle Holder and inspect.
