Integrated Control Panel. The electrical requirements for the integrated control panel
are 208/230/460 VAC, 3-phase, 60 Hz power. Only a qualified electrician should
connect this device to an appropriate protected power source. If your AirWall unit has
this optional control panel, the electrical schematic will be supplied with the manual.
PNEUMATIC CONTROL CONNECTIONS
In addition to the electrical connections, two (2) pneumatic control connections must be
made from the AirWall unit to the Photohelic Gage. These connections should be made
with ¼ in. (6mm) nylon poly tube.
To complete the pneumatic control connections:
1.
Push the 1/4 in. (6mm) tubes into the brass bulkhead quick-disconnect
fittings located on the AirWall unit.
2.
Connect these two (2) lines to the Photohelic gage as follows:
a.
Connect the high-pressure tube from the Photohelic gage to the
lower port on the AirWall unit.
b.
Connect the low-pressure tube to the upper port on the AirWall
unit.
COMPRESSED AIR CONNECTION
The air pressure accumulator tank located inside the AirWall upper air plenum should
be supplied with clean, dry compressed air between 90 and 110 psi. Total air
consumption is variable and is dependent on the type and concentration levels of
