EQUIPMENT INSTALLATION

4-3.1 General
All Kidde ECS System equipment must be installed to facilitate proper inspection, testing,
manual operation, recharging and any other required maintenance as may be necessary.
Equipment must not be subject to severe weather conditions or mechanical, chemical or other
damage that could render the equipment inoperative. Equipment must be installed in
accordance with NFPA Standard 2001.
The HFC-227ea cylinder/valve assemblies must be handled, installed and
serviced in accordance with the instructions contained in this paragraph and
Compressed Gas Association (CGA) pamphlets C-1, C-6 and P-1. CGA pamphlets
may be obtained from: http://www.cganet.com. Failure to follow these
WARNING
instructions can cause HFC-227ea cylinders to violently discharge, resulting in
severe injury, death and/or property destruction.
4-3.2 Distribution Piping and Fittings
4-3.2.1 Threads
Threads on all pipe and fittings must be tapered threads conforming to ANSI Specification 8-
20.1. Joint compound, tape or thread lubricant must be applied only to the male threads of the
joint.
4-3.2.2 Pipe
Piping must be of noncombustible material having physical and chemical characteristics, such
that its integrity under stress can be predicted with reliability. The latest version of the flow
calculation software program has only been verified for the specific types and schedule of pipe
and fittings covered in this manual. There is a risk that the system may not supply the required
quantity of agent in unbalanced systems when other pipe types and fittings are used.
