Installation
Wall Mounting HP Reserve Header
High pressure reserve header components
may be shipped in several cartons. One carton
will contain control section assembly consisting of
master valve, regulator assembly, and reserve
low pressure switch as shown in Figure 6.
Additional shipping cartons contain header
extensions, cylinder pigtails, and header wall
brackets. Depending on number of cylinders,
header extensions are configured with two or
three cylinder inlets. Large reserve headers may
also include combinations and multiples of each
type of header extension.
1. Remove large nut and plug from right side of
control section. Attach appropriate header
extension to control section. Position cylinder
inlet connections of each header extension so
they are pointing out . Additional header
extensions may be attached end to end if
required. Install large nut and plug previously
removed on end of last header extension
(Figure 7).
2. Mark wall 60-1/2" from finished floor in
location where high-pressure reserve header
will be mounted. Convert mark to level
horizontal line approximately as long as
assembled high-pressure reserve header.
3. Depending upon number of header
extensions, two or more header brackets will
be provided. Header brackets should be
positioned along length of high-pressure
reserve header assembly and should contact
header directly between cylinder connections.
A header bracket will typically be provided for
each header extension. Measure centerline
distance between header brackets and
transfer those measurements to horizontal line
described in step 2 as shown in Figure 8.
4. Position header bracket against wall and align
top of bracket with horizontal line. Center
brackets with centerline marks from step 3.
Attach brackets to wall using appropriate
anchors (by others). 3/8" diameter anchors
are recommended.
5. Set complete reserve header on top of wall
brackets and assemble u-bolt and bracket
hardware as shown. Tighten u-bolt nuts.
6. One more wall bracket should be installed to
support left side of reserve header assembly
as shown in Figure 9. Bracket will be slightly
lower than others and should be attached to
reserve header in order to mark mounting hole
location on wall.
7. Tighten all header extension unions and plugs.
Ensure all cylinder connections point away
from wall.
NOTE:
A mounting height of 60-1/2” allows for adequate
clearance beneath reserve header assembly
when utilizing standard “H” size cylinders (55” tall
overall). Bracket mounting height should be
increased proportionally if taller cylinders are to
be used.
