WARNING
• Always verify that the piping system has been
completely depressurized and drained immediately prior
to installation, removal, adjustment, or maintenance of
any Victaulic
® products.
• Confirm that any equipment, branch lines, or sections of piping that may
have been isolated for/during testing or due to valve closures/positioning are
identified, depressurized, and drained immediately prior to installation, removal,
adjustment, or maintenance of any Victaulic
® products.
Failure to follow this instruction could result in death or serious personal injury and
property damage.
1. Verify that the system is depressurized and drained completely before attempting to
remove a Series AH1-CC, AH1-CC-LP, AH2-CC, AH2-CC-LP, or AH2-CC-300 Flexible
Hose from the sprinkler piping.
2. While supporting the Style 108 Coupling, loosen the nut until backed off no further
than flush with the end of the bolt. Carefully remove the flexible hose/coupling assembly
from the sprinkler piping.
3. Fully disassemble the Style 108 Coupling from the inlet end of the Series AH1-CC,
AH1-CC-LP, AH2-CC, AH2-CC-LP, or AH2-CC-300 Flexible Hose by removing the nut,
bolt gasket, and linkage from the housing. Inspect all components for any damage or
wear. If any damage or wear is present, use a new Victaulic
®
-supplied coupling assembly.
4. Verify that the outside surface of the sprinkler piping, between the groove and the
end of the sprinkler piping, is generally free from indentations, projections, weld seam
anomalies, and roll marks to ensure a leak-tight seal. All oil, grease, loose paint, dirt, and
cutting particles shall be removed.
The sprinkler piping’s outside diameter (“OD”), groove dimensions, and maximum
allowable flare diameter shall be within the tolerances published in current Victaulic
®
IGS
™
specifications, publication 25.14, which can be downloaded at victaulic.com.

new, Victaulic
®

inlet end of the Series AH1-CC, AH1-CC-LP,
AH2-CC, AH2-CC-LP, or AH2-CC-300 Flexible
Hose, as shown to the left.
