Medical Gas Supply System
2.3
Cylinder Connection.
All manifolds other than O2, He, CO2O2, O2CO2, HeO2,
O2He, ISO N2O, ISO Inst. Air, and ISO Med. Air utilize
24" length flexible stainless-steel braided pigtails. All
cylinders on the right bank of the manifold, even those
placed directly beneath should be positioned, so that the
cylinder outlets face right. All cylinders on the left bank of
the manifold, even those placed directly beneath should
be positioned so that the cylinder outlets face left.
Figure 7a illustrates a typical 4 x 4 manifold system
utilizing 24" length flexible pigtails. O2, He, CO2O2,
O2CO2, HeO2, O2He, ISO N2O, ISO Inst. Air, and ISO
Med. Air manifolds are supplied with pre-formed rigid
copper pigtails. All cylinders on the right bank of the
manifold, even those placed directly beneath should
be positioned so that the cylinder outlets face right. All
cylinders on the left bank of the manifold, even those
placed directly beneath should be positioned, so that
the cylinder outlets face left.
Figure 7b illustrates a typical 4 x 4 O2, He, CO2O2, O2CO2,
HeO2, O2He, ISO N2O, ISO Inst. Air, and ISO Med. Air
manifold utilizing pre-formed rigid copper pigtails.
2.3.1
Remove the plastic shipping caps from the
manifold header pigtail connections.
2.3.2
Connect one end of pigtail assembly to header
connection. Coiled end of rigid copper pigtails attaches
to header connection.
CAUTION! Only persons who have had specific
training in the safety of medical gases, manual handling
techniques and cylinder changing procedures should be
allowed to change cylinders on medical gas manifolds or
medical equipment.
2.3.3
Position the gas cylinders as shown in Figure 7.
Secure each cylinder to wall or floor stand with chains
or straps.
2.3.4
Connect the pigtails to each cylinder. Rigid
copper pigtails used on O2, He, CO2O2, O2CO2, HeO2,
O2He, ISO N2O, ISO Inst. Air, and ISO Med. Air manifolds
are preformed to approximate required shape. Lower
end of rigid copper pigtails must be bent 90° toward
cylinder outlets.
2.3.5
Tighten all pigtail connections firmly. Do not
over-tighten.
WARNING! All pigtail assemblies are shipped
in sealed bags and are cleaned as if for oxygen use.
Manifold header connections are clean and capped. Do
not unpackage or remove any cap until ready to install.
During installation use care to maintain cleanliness.

WARNING!
•
Do not repeatedly bend, sharply bend, or twist
copper pigtails as damage to tubing may occur.
•
Do not bend flexible pigtails into a radius smaller
than 3".
•
Always secure 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.
CAUTION! Prior to connecting pigtail to cylinder,
slightly open and close each cylinder valve to blow out
dirt and debris.
NOTE - Both ends of flexible pigtails are the same. Either
end may be connected to manifold header. Rigid copper
pigtails are preformed and must be connected as shown
in Figure 11. Tighten all pigtail connections firmly. Do not
over-tighten.
