WARNING
Failure to observe the following before
connecting the equipment to the compressed-
air source can cause serious injury from the
sudden release of trapped compressed air:
Lockout and tagout the compressed-air
supply.
Bleed the compressed-air supply line.
2.3.1
Refer to Paragraph 2.3.2 to determine the
recommended air-supply hose size, then refer to Figure
6 and apply thread sealant to the male threads of an
air fitting that is compatible with the air-supply hose
fitting, and install it onto the 1/2-NPT air filter located
under the cabinet hopper. The style of connection shown
in Figure 6 is for reference only.
2.3.2
Install an isolation valve at the air source to
enable depressurization for service, and refer to the
table in Figure 7 to determine the minimum ID air-supply
line to the cabinet air inlet. A smaller diameter hose may
reduce blasting efficiency.
WARNING
To avoid the risk of injury from compressed air,
install an isolation valve and bleed-off valve
where the air supply is tapped into the
compressed-air system. This enables a lockout
and tagout procedure and depressurization of
the compressed-air line before performing
maintenance.

Connect the air line from the air source to the
air-filter inlet.
WARNING
Hose disconnection while under pressure can
cause serious injury or death. Use safety lock
pins or safety wire to lock twist-on couplings
together and prevent accidental separation, and
also use safety cables to prevent hose from
whipping should separation occur. Safety lock
pins and safety cables are listed in
Section 9.1:
Optional Accessories.
2.3.4
Refer to the dust collector owner’s manual and
connect a compressed-air line to the pulse manifold.
2.4
Ground the Cabinet
and Dust Collector
2.4.1
To prevent static electricity buildup, attach an
external grounded wire from an earth ground to the
grounding lug on the left rear of the cabinet. Refer to the
dust collector owner’s manual and connect a ground
wire to the dust collector.
2.5
Connect Electrical Service
WARNING
Shorting electrical components can result in
serious injury or death from electrical shock
and can cause equipment damage. Electrical
power must be locked out and tagged out
before performing any electrical work. All
electrical work or any work done inside a
control panel or junction box must be
performed by a qualified electrician and comply
with applicable codes.
All wiring external of the cabinet is provided by the user
to comply with local electrical codes.
2.5.1 Three-phase wiring
A wiring schematic is stowed inside the control panel
mounted on the back of the cabinet. After wiring is
completed, keep a copy of the schematic with the
manual for future reference and for electrical
replacement parts.
2.5.1.1
Refer to the wiring schematic and wire from the
users disconnect to the panel and from the panel to the
dust-collector motor, per instruction on the motor data
plate.
