Part No. 6-847703-00 Rev. C00
72” black flex pigtails are connected between
manifold control panel left bank and liquid
containers (Figure 15 and 16). Remove plastic
shipping caps from manifold control panel inlets.
Connect either end of 72” black flex pigtail to
manifold left side inlet. Connect other end of
pigtail to gas outlet of liquid container.
Manifold’s right bank and all high-pressure
reserve header assemblies other than oxygen
utilize 24” length flexible stainless-steel braided
pigtails.
Figure 15 illustrates a typical LQ x HP manifold
and 5 cylinder high-pressure reserve header
assembly utilizing flexible pigtails.
Manifold’s right bank and high-pressure
reserve header assemblies for oxygen service are
supplied with pre-formed rigid copper pigtails.
Figure 16 illustrates a typical LQ x HP manifold
and 5 cylinder high-pressure reserve header
assembly utilizing pre-formed rigid copper pigtails.
To install manifold right bank and high-pressure
reserve header pigtails:
1. Remove plastic shipping caps from manifold’s
right bank and reserve header pigtail
connections.
2. Connect one end of pigtail assembly to
manifold right bank or reserve header
connection. Coiled end of rigid copper pigtails
attaches to manifold right bank or reserve
header connection.
3. Position gas cylinders as shown in Figures 15
and 16. Secure each cylinder to wall or floor
stand with chains or straps.
4. Connect pigtails to each cylinder. Rigid
copper pigtails used on oxygen systems are
pre-formed to approximate required shape.
Lower end of rigid copper pigtails must be
bent 90° toward cylinder outlets.
WARNING:
• All pigtail assemblies are shipped in sealed
bags and are cleaned as if for oxygen use.
Manifold control panel and reserve header
connections are clean and capped. Do not
unpackage or remove any cap until ready to
install. During installation use care to
maintain cleanliness.
• Do not connect 72” black flex pigtail to high
pressure reserve header assembly. This type
of pigtail must only be connected between
manifold control panel and liquid containers.
• Do not repeatedly bend, sharply bend, or
twist copper pigtails as damage to tubing may
occur.
• Do not bend high-pressure flexible pigtails
into a radius smaller than 3".
• Always secure high-pressure cylinders with
racks, straps, or chains. Unrestrained
cylinders may fall over and damage or break
off cylinder valve.
CAUTION:
• Do not use thread sealant on header or pigtail
connections.
• Prior to connecting pigtail to cylinder, slightly
open and close each cylinder valve to blow
out dirt and debris.
Installation
Pigtail / Cylinder Connection
NOTE:
Both ends of flexible pigtails are the same. Either
end may be connected to manifold header. Rigid
copper pigtails on oxygen manifolds are
pre-formed and must be connected as shown in
Figure 16.
5. Tighten all pigtail connections firmly. Do not
over-tighten.
