Emergency Reserve Manifold
Figure 12 - Typical cylinder header extension layout details (upgrade to 2 x 6), extension kits from
table 3.
NOTE - For additional cylinders continue to add the dimensions of the last header kit from either figure 9
or 10 for either single or double racks.
2.4 Cylinder Connection
CAUTION: Ensure that all the tailpipes
supplied are the correct gas type. The gas ID
is stamped onto the nut that connects to the
header non-return valve.
2.4.1 Connect the tailpipes to the non-return
valves on the header racks as shown in figure 13.
2.4.2 Refer to hospitals/site policy for safe
cylinder handling (See section 4.6 for typical
cylinder handling safety check list), move the
cylinders into place (see figures 3, 7, 9-12) ready
for connection to the tailpipes.
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.
2.4.3 Connect the cylinders to the pin indexed
clamp on the tail pipe, as shown in figure 13.
Ensure the bodok seal is in place at the opposite
side to the thumb screw on the pin index clamp
before connection.
NOTE - Pipe index tailpipes to BE EN ISO 21969 are
supplied as standard. Alternative connection types
are available on request.
2.4.4 See section 4.7 for cylinder operation
procedure

2.5 Installation check
2.5.1 Ensure that all tailpipes are connected to
the cylinders and manifolds on both sides and
that the restraint chains are secure around the
cylinders.
2.5.2 Isolate the panel from the pipeline using
isolation valve 'B' (shown in figure 1).
2.5.3 Ensure that the left-hand bank high-
pressure isolation Valve '1' (Figure 1) is fully open
by turning anticlockwise, and the right-hand high-
pressure isolation valve '2' (Figure 1) is fully closed
by turning clockwise.
2.5.4 Using 1 cylinder, slowly pressurise
the left-hand bank (see section 4.7 - Cylinder
operation). The left-hand contents gauge should
indicate full cylinder pressure. The distribution
system pressure gauge on the regulator (adjust
as necessary) should read typically as per table 4
(Section 4 - Principle of Operating).
CAUTION: It would be recommended to
set the ERM line pressure at least 0.2 bar below
the main supply source pressure at full design
flow to ensure the emergency manifold does
not supply the pipeline during normal primary
source operation.
2.5.5 Check for leaks. Now ensure all left-hand
bank cylinders are closed.
2.5.6 Open valve 'C' and relieve the pressure
from within the ERM from the sampling outlet
then close valve 'C' (Item 10 & 11, Figure 1).
