airborne dust and the set points used for determining the cleaning cycle. Typical air
consumption will be approximately 1.8 CFM per AirWall unit.
Use the following procedure to complete the compressed air connection. Although the
AirWall unit is designed for a 1 in. NPT supply line, the supply line may be smaller than
1 in. but should not be smaller than .375 in. or excessive accumulator recharge time
will result. The 1 in. coupling in the tube sheet may be bushed for smaller air supply
lines.
NOTE: Since each customer installation is different, EECI has not cut
the hole through the AirWall unit which is necessary for the
installation of the air supply line.
1.
Cut a hole in the side of the dirty-air (lower) plenum bulkhead sufficient in
size to accommodate the supply line diameter.
2.
Externally mount a shut-off valve with a nipple or stub pipe extending
through the hole and connect the pipe to the fitting provided in the bottom
of the tube sheet. This connection is positioned between the back two
rows of filter openings.
2.
3.
Connect an air hose or hard plumbing from the compressed air source to
the shut-off valve on the side of the AirWall unit.
4.
Slowly open the shut-off valve to allow pressure to build in the accumu-
lator tank. When the tank has reached full line pressure of 90 to 110 psi,
close the shut-off valve.
5.
Inspect the tank, valves and fittings, including the solenoid valves inside
the cleaning system control box, for air leaks.
6.
Tighten fittings and clamps as required.
7.
Reopen the air shut-off valve.
INSTALLING FILTER CARTRIDGES
1.
Remove the filter cartridges from their boxes. Inspect for damage.
2.
Locate the support rod assemblies.
3.
Carefully guide the threaded rod of the support rod down through the filter
cartridge and through the center hole in the bottom of the cartridge. Place
a filter cartridge retaining nut on the threaded end of the support rod.
