Nortec AirFog Installation Manual |

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: Nortec 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 Nortec 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 Nortec Octo units are to be controlled from a single control panel then “T” off
the pilot air pressure line to connect the other Nortec OCTO units as illustrated in Figure
23: Four Nortec Octo Units With A Single Control Panel. If more than four Nortec Octo’s
are to be controlled from one control panel, use a pilot air regulator or a volume booster
for the pilot line.
Nortec 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 Nortec Octo hardware is explained in the under
Control Panel section.
The nozzles on the Nortec 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: Nortec AFE Octo Nozzle Spray Pattern
helps in visualization of these Nortec AIRFOG plumes.
