2.3
Connect Compressed-Air-Supply Lines
A separate air line is required for the dust-collector
pulse. The line may be connected to the auxiliary-air port
on the cabinet plumbing, as shown in Figure 6.
WARNING
Failure to observe the following before connecting
the equipment to the compressed-air source can
cause serious injury or death from the sudden
release of trapped compressed air:
Lockout and tagout the compressed-air supply.
Bleed the compressed-air-supply line.
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.
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
Refer to the table in Figure 5 to determine the
minimum ID air-supply line to the cabinet air inlet. A
smaller diameter hose may reduce blasting efficiency.

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.
