Nortec AFE Octo Systems
Nortec Octo systems are partially self contained and are between the simple Nortec MINI self-
contained installation and the modular Nortec AFE systems. The Designer’s drawings and parts
list will define the configuration. The only installation difference between the full modular
system and the Nortec Octo is that the vacuum valve and pilot air regulator are located inside the
Nortec Octo case as illustrated in Figure 19: Nortec Octo Layout and Interfaces.
The Nortec Octo interfaces are:
3/8” O.D. plastic or soft copper water supply line rated at a minimum pressure of 25 psig
½” O.D. plastic or soft copper air supply line rated at a minimum pressure of 90 psig
1/4” O.D. plastic tubing for command air pressure (pilot air)
Isolation valves for both air and water lines
Hanging hardware
Chains
Threaded rod
Support anchors
Nortec AFE Control panel
120 VAC standard electrical receptacle
Humidity control device (Humidistat)
Installation Procedure
Nortec Octo units are designed to be suspended from the ceiling by either a threaded rod or
chains. Nortec Octos with nozzles on only one side may also be mounted on a wall or pillar
(single sided configurations). Prior to mounting, ensure there are no obstacles such as duct
work, lighting, large equipment, etc., Please refer to Figure 20: Nortec Octo Spray Pattern for
further information. The Nortec Octo unit should be installed as high as possible above the
floor, any equipment or work space. Adiabatic cooling maybe uncomfortable to people
occupying workstations directly beneath the Nortec Octo systems. The recommended height
above the floor is 20 ft (6.1 m) and 18” below ceiling joists.
When using chains to suspend the Nortec Octo, ensure the chains are rated for the units
weight (64 lbs) and that all local building codes are followed.
In general:
Each Nortec Octo weighs up to 64 lbs (29 kg).
Install the four 3/8” NC eye bolts into the four mounting holes on the unit using the supplied
lock washers & nuts.
Install field supplied supporting chains or rods from the ceiling then raise the unit up into
location and secure in place.
Note:
Always hang units, never use a cradle assembly, which can interfere with spray
pattern or restrict access for service.
