Manual No. 30421
1.11.7 Plastic media:
Plastic and similar lightweight
and/or nonaggressive media are generally not
recommended for suction-style cabinets because the
lower blast velocity of suction blasting combined with the
softer and lighter-weight media do not provide the media
impact for productive blasting. Best performance from
plastic media is achieved with pressure blasting,
requiring a pressure vessel with a 60-degree conical
bottom. Refer to Clemco’s Aerolyte cabinet line.
1.11.8 Bicarbonate of soda:
Bicarbonate of soda is
not recommended for use in standard cabinets. Bicarb is
a one-use media, which quickly saturates the filter
cartridge(s). Best performance from bicarb media is
achieved with pressure blasting, requiring a pressure
vessel. Refer to Clemco’s Aerolyte cabinet line for
cabinets that are specifically designed for use with
bicarbonate of soda.

Compressed-Air Requirements
1.12.1
The size of the compressor required to operate
the cabinet depends on the size of the air jet and
blasting pressure. Unless otherwise specified, cabinets
are supplied with a No. 5 (5/32" orifice) jet. Refer to the
table in Figure 4 to determine air consumption. Consult
with a compressor supplier for a suggested compressor
size based on the air consumption.

1.12.2
The compressed-air filter at the power module’s
air-inlet connection removes condensed water from the
compressed air. Its use is especially important in areas
of high humidity or when fine-mesh media are used.
Moisture causes media to clump and inhibits free flow
through the feed assembly. If the filter does not remove
enough moisture to keep media dry and flowing, it may
be necessary to install an air dryer or aftercooler in the
air-supply line.
1.13
Electrical Requirements
1.13.1
Standard cabinets are provided with 1 HP,
120/230 VAC, 1 PH, 60 Hz (wired 120). FLA (full load
amps) are as follows: 120/12, 208/6.6, 230/6.2.
1.13.2
If the motor is standard 120-volt, single-phase, a
power cord is supplied.

INSTALLATION
Unless noted otherwise, the sequence of assembly in
Sections 2.2 through 2.8 may be done in any order that
is convenient for the installer.
2.1
General Installation Notes
Select a location where compressed air and
electrical service are available.
The cabinet location must comply with OSHA and
local safety codes.
Arrange the power module and cabinet in any
convenient positions. Flex-hose connection and
metering valve should face toward the cabinet to
allow for as few bends as possible to prevent wear.
Place the power module and cabinet in their
final positions before making compressed-air
connections, hose, and electrical connections.
The electrical cord and tubing (shown in Figure 7)
connect power module to the cabinet extends from
the power module. Space the power module and
cabinet to maintain slack in the cord and tubing.
Provide enough clearance at the dust collector for
cartridge maintenance and to remove the dustbin.
Allow for full access to all doors and service areas
and for efficient handling of large parts.
All air fittings and connections must be wrench-tight.
2.2
Electrical and Tubing Connections from the
Power Module to the Cabinet – Figure 7
2.2.1
After the power module and cabinet are in their
final positions. Plug the female cord connector into the
mating male connector located on the back of the
cabinet’s gauge panel. Pull the latch down and over the
cord connector to lock it in place.
