AirFog Installation Manual | 23
Mounting using threaded rods requires installing field supplied 3/8” NC supporting rods
from the ceiling, raising the unit up into location and securing it to the support rods using
the supplied washers and nuts.
Both water and air lines should have an isolation valve installed near the unit as
illustrated in Figure 23: Octo Air And Water Interfaces. Water connection at the unit is
designed for 3/8” plastic tubing; however, if soft copper pipe is to be used, replace the
plastic sleeve in the fitting with the supplied brass sleeve. Air connection is designed for
½” plastic tubing. If soft copper pipe is to be used, replace the plastic sleeve in the
fitting with the supplied brass sleeve.
For a standard Octo unit, a separate control panel and 1/4” O.D. plastic tubing for pilot
line is required. To install this line the fitting on the unit is a push in style located above
the main air connection. Simply cut the tubing square and push one end into the fitting.
Route the line back to control panel location.
If multiple Octo units are to be controlled from a single control panel then “T” off the pilot
air pressure line to connect the other OCTO units as illustrated in Figure 23: Four Octo
Units With A Single Control Panel. If more than four Octo’s are to be controlled from one
control panel, use a pilot air regulator or a volume booster for the pilot line.
Octo Plus units do not require a separate control panel as there is one mounted within
the unit. All that is necessary is to connect it electrically as explained in this manual
under Electrical Wiring.
Control Panel installation for standard Octo hardware is explained in the under Control
Panel section.
The nozzles on the Octo units are pointed straight forward when shipped but these can
be oriented in any direction that will not have the plume strike a solid object or another
plume for at least 16 feet. Figure 24: AFE Octo Nozzle Spray Pattern helps in
visualization of these AIRFOG plumes.
