SECTION IV INSTALLATION AND ASSEMBLY OF EQUIPMENT.
3-9
General
3-9.1 In the following installation instructions, reference is made to the drawings and illustrations contained in Chapter 2.
It is recommended that the reader first become well acquainted with these instructional drawings and illustrations and
then refer back to them as necessary and as called for in the installation instructions for a full understanding of the
installation procedure.
3-9.2 The recommended order of installation is as described. In general, it is recommended that major equipment be
installed first, followed by major fittings and valve assemblies, and then by the interconnecting hoselines.
3-9.3 Internal cleanliness in the installation of all equipment, valves, fittings and hoses cannot be over-emphasized.
Sand, rocks, rags, tools, clothing, etc., left inside will end up blocking flow or damaging equipment. Positive action must
be taken to avoid the entry of dirt and contaminants. Leave protective caps and plugs in place until actually ready to
make a connection. Just prior to closing a joint, inspect the parts being assembled and remove any foreign material.
CAUTION
INTERNAL CLEANLINESS
Do not remove protective caps or plugs until actually ready to assemble and install parts and
equipment. Take special care to avoid getting dirt, rags, tools or other foreign materials
inside hoses, piping, valves, fittings, or equipment. Thoroughly inspect all parts internally
immediately before assembly. Remove any foreign materials observed. To assure
cleanliness, flush or swab out hoselines and piping that cannot be readily observed if there
has been any possibility for of the entry of dirt or other materials. Foreign materials in the
system will plug flow or damage equipment which can result in a serious safety hazard as well
as interrupted operations.
NOTE
COUPLING CLAMPS AND GASKETS
Coupling clamps are normally shipped loose with the gaskets packaged separately or on
assemblies. They are clamped in place without the gasket installed. Gaskets must be slipped
over the pipe or fitting ends and the coupling clamp placed over them. See paragraph 3-13.10
and U.S. Army technical manual TM-5-343 for acceptable procedures.
