1.1.3 PanBlast Standard Terms and Conditions of Sale
apply. Contact your local PanBlast office or
distributor should you require any further
information or assistance.
1.2 ! WARNING ! – READ THIS SECTION
CAREFULLY BEFORE USING THIS
EQUIPMENT/APPARATUS.
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
equipment (SAR) 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(s) 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 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 electrical wiring or
components must only be carried out by
suitably qualified and registered electrical
trades’ personnel.
1.3.4 Under no circumstances should any safety
interlocks / lock-outs 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
source 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. Pressure 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 Safety 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
and precautions to ensure the safety of the
operator and all personnel.
1.3.10 The operator should carry out a daily inspection
before start up of all wearing and safety items
to ensure that they are in correct operating
order. In particular check all blast hose
couplings and nozzle holders, ensuring that all
couplings have engaged correctly and the
safety locking pins are fitted and in good
condition. Always install safety whip check
cables at every 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 that all
screws are engaged.
2.0 INTRODUCTION
2.1 These instructions cover the operation and
maintenance of PanBlast™ Tandem Remote
Control Inlet Valve models as follows:
-BAC-RC-PB-0274 Tandem Valve 3/4"
-BAC-RC-PB-0275 Tandem Valve 1"
-BAC-RC-PB-0276 Tandem Valve 1-1/4"
-BAC-RC-PB-0277 Tandem Valve 1-1/2"
2.2 The PanBlast™ Tandem Remote Control Inlet
Valve is a diaphragm driven spring type remote
control inlet valve. The PanBlast™ Tandem
Remote Control Inlet Valve is ideally suited for
blast pots with plumbing configurations of 3/4"
through to 1-1/2" with an operating pressure
not exceeding 1034kPa (150psi).
2.3 The PanBlast™ Tandem Remote Control Inlet
Valve is generally used in conjunction with a
separate remote exhaust valve on pressure
release blast pots and Corsa II Abrasive
Metering Valves on pressure hold type blast
pots. PanBlast recommends that the Tandem
Remote Control Inlet Valves are operated and
activated by either AirStop or AirStop II Remote
Control Deadman Handles.
NOTE: UNDER OSHA 1915:34(c)(1)(iv) DEAD
MAN CONTROL. A DEADMAN CONTROL
DEVICE SHALL BE PROVIDED AT THE NOZZLE
END OF THE BLAST HOSE EITHER TO
PROVIDE DIRECT CUTOFF OR TO SIGNAL THE
POT TENDER BY MEANS OF A VISUAL AND
AUDIBLE SIGNAL TO CUT OFF THE FLOW, IN
THE EVENT THE BLASTER LOSES CONTROL
OF THE HOSE. THE POT TENDER SHALL BE
AVAILABLE AT ALL TIMES TO RESPOND
IMMEDIATELY TO THE SIGNAL.

3.0 OPERATING INSTRUCTIONS
! WARNING ! – READ THIS SECTION
CAREFULLY BEFORE USING THIS EQUIPMENT/
APPARATUS.
3.1 Before connecting the main compressed air
supply, check the operation of the remote
control handle and ensure that the handle
safety lock button or lever lock is operational
and that the handle lever is free in its action.
3.2 Ensure that all hose fittings are secured and
coupling safety locking pins are engaged.
3.3 It is recommended that all Tandem Remote
Control Inlet Valves should be supplied with a
1-1/4" bore or larger compressed air line to
provide adequate air supply and volume.
3.4 Connect the twinline hose from the marked (IN)
port of the remote control handle to a live air
source. Proceed to connect the second twinline
hose from the remote control handle marked
(OUT) port to the Tandem Remote Inlet Valves
pilot air activation port.
3.5 Ensure the Tandem Remote Control valve is
installed correctly with arrow sign pointing
towards incoming compressed air flow. Refer to
to picture shown below.
3.6 Start the compressor and slowly open the main
air supply ball valve to the blast pot.
3.7 Depress the safety lever lock or safety lock
button on the remote control handle assembly
and depress the lever handle. This will activate
the remote control handle and send a return
signal to the Tandem Remote Control Inlet
Valve, opening the inlet valve, which will then
initiate the abrasive blasting process.
3.8 Release the remote control handle lever to stop
blasting; this automatically engages the safety
lock preventing inadvertent operation of the
remote control handle. This in turn closes the
Tandem Remote Control Inlet Valve and
terminates the compressed air from flowing
through the Tandem valve.
4.0 MAINTENANCE
! WARNING ! THE SYSTEM MUST BE IN
SHUT DOWN MODE AND THE COMPRESSED
AIR DISCONNECTED BEFORE PERFORMING
ANY MAINTENANCE WORK. FAILURE TO DO
SO MAY RESULT IN PREMATURE ACTIVATION
OF THE SYSTEM THAT MAY CAUSE SERIOUS
INJURY OR DEATH.
4.1 Periodically the valve should be disassembled
and checked for wear and tear, on the
diaphragm, shaft and O-rings. Check for any
premature wear of the diaphragm and scoring
of the shaft, if either shows signs of wear, they
or the valve should be replaced.
4.2 Check the valve body for wear and tear, and
inspect the condition of the seat gasket for
cracking, replace as required.
4.3 Check the condition of the spring for wear and
tear, if there are signs of wear and tear, this
should be replaced.
4.4 Check the condition of the IN & OUT threads of
each port to ensure they are not worn and
functional.
5.0 TROUBLE SHOOTING GUIDE
PROBLEM PROBABLE SOLUTION
Unable to start
blasting
operations.
Make sure that the twinline hoses
have been connected in the correct
configuration.
Check the main air supply.
Check the blast nozzle for any
blockages.
Check if the pop up valve is fully
lifted, if a rattle or hovering can be
detected there is insufficient air
supply.
Make sure that there are no air
leaks in the twinline hoses.
Check the orifice of the nipple in
the supply fitting to the handle and
ensure that it is not blocked.
Check if there is air escaping from
the exhaust valve when the
deadman remote handle is
depressed. If so, the diaphragm
should be inspected for wear and
tear, replace as required. Also
check and ensure that the rubber
gasket in the seat holder is not
worn.
Blasting operation
cannot be shut
down or stopped.
Verify that the twinline hoses have
been connected to the remote
control handle correctly. Check that
the supply line is connected to the
handle (IN) fitting and signal line to
the handle (OUT) fitting.
Check for and ensure that the
remote control handle plunger is
not jammed or faulty.
If the blasting cannot be stopped
when the remote control handle
has been released and the blast pot
continues to blast then it is likely
that the shaft in the tandem valve
has seized up. Disassemble and
check the shaft, O-rings, spring,
diaphragm and housing bore.
