SYSTEMS
(1)
Octo systems are partially self contained and are between the simple Mini self-
contained installation and the modular AFE systems. The Designer’s drawings and
parts list will define the configuration. The only installation difference between the
full modular system and the Octo is that the vacuum valve and pilot air regulator
are located inside the Octo case as illustrated in Figure 3 Octo Layout and
Interfaces.
(2)
The Octo interfaces are:
a. 3/8” O.D. plastic or soft copper water supply line rated at a minimum
pressure of 25 psig
b. ½” O.D. plastic or soft copper air supply line rated at a minimum pressure
of 90 psig
c. 1/4” O.D. plastic tubing for command air pressure (pilot air)
d. Isolation valves for both air and water lines
e. Hanging
hardware
i. Chains
ii. Threaded
rod
iii. Support anchors
f. AFE Control panel
g. 120 VAC standard electrical receptacle
h. Humidity control device (Humidistat)
C. INSTALLATION
PROCEDURE
(1)
Octo units are designed to be suspended from the ceiling by either a threaded rod
or chains. 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
4 Octo Spray Pattern for further information. The 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 Octo
systems. The recommended height above the floor is 20 ft (6.1 m) and 18” below
ceiling joists.
(2)
When using chains to suspend the Octo, ensure the chains are rated for the units
weight (64 lbs) and that all local building codes are followed.
(3) In
general:
(a)
Each Octo weighs up to 64 lbs (29 kg).
(b)
Install the four 3/8” NC eye bolts into the four mounting holes on the unit
using the supplied lock washers & nuts.
(c)
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.
