Odorizer Installation
When used, odorizers should be located immediately downstream of each selector valve. For
systems protecting a single hazard, a single odorizer can be located immediately downstream
of the discharge manifold.
Note: An odorizer assembly, Part Nos. 81-897637-000 and 10030080, shall be installed
Note: An odorizer assembly, Part Nos. 81-897637-000 and 10030080, shall be installed
upstream of the lock-out valve. In the event a safety outlet ruptures in a locked-out
system, the scent from the odorizer will provide a warning that carbon dioxide has
vented into the area by the safety outlet.
Odorizers must be attached to the discharge piping in the upright position using a 1-1/2 inch
standard galvanized close nipple. When a welded connection is required, use a 1-1/2 inch
standard pipe, 1-3/4 inches long, threaded on one end. Install odorizer assembly after welding.
1. Attach the odorizer assembly to the piping.
2. Remove the union nut and cylinder body from the odorizer assembly, leaving just the union
1. Attach the odorizer assembly to the piping.
2. Remove the union nut and cylinder body from the odorizer assembly, leaving just the union
headpiece attached to the piping.
3. Use a small pick or slotted screwdriver to remove the spiral retaining ring and the circular
screen.
4. Carefully insert the odorizing cartridge into the cylinder body. This is most easily done by
holding the cylinder body on its side. The narrow tip end of the odorizing cartridge should
go into the cylinder body first. DO NOT drop the odorizing cartridge into the cylinder body,
as this will most likely break the odorizing cartridge.
5. Replace the screen and secure with the spiral retaining ring. Make sure the o-ring is still in
its groove before placing the cylinder body back onto the union head piece. A small amount
of o-ring lubricant can be used to help keep the o-ring in place.
6. Thread the union nut back onto the odorizer assembly and tighten the assembly.
Figure B-11. Odorizer Installation
CAUTION
To prevent damaging the odorizing cartridge during testing, it is recommended
that the odorizing cartridges not be installed until after system testing of the
discharge piping is complete. For periodic maintenance after the system has
been installed and in use, remove the odorizing cartridge prior to any testing of
the discharge piping.
