NOTE:
Always hang units, never use a cradle
assembly which can interfere with spray pattern or
restrict access for service.
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 as
shown in Figure #21 (“Ceiling Mounting Of Octo”).
If water and air supply lines are not already
installed at this location then complete this installation.
Both water and air lines should have an isolation valve
installed near the unit as illustrated in Figure #22
(“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
on page 10 of this manual under Electrical Wiring.
Control Panel installation for standard Octo
hardware is explained on page 9 of this manual under
Control Panel.
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 Plumes”) helps in visualization
of these AIRFOG plumes.
Figure #29. The center vertical rail is to be
mounted in the center of the duct and attached to the
manifold rails using the supplied hardware. It is
important that the center vertical rail is sized correctly
and securely fastened to the top and bottom of the
duct.
