Manifold Cabinet Wall-mounting
To have clearance beneath the manifold cylinders,
measure a distance of 60” from the floor and mark it
on the wall. Using a level, draw a horizontal line at the
mark. Place the mounting bracket on the wall, lining up
the horizontal line with the bottom of the bracket, and
mark the 4 mounting holes on the wall.
Use appropriate mounting hardware (not included)
to fasten the mounting bracket to the wall
Identify the slot on the back of the manifold near
the top, and the corresponding tab on the top of the
mounting bracket. Lift the manifold cabinet just over
top of the mounting bracket and lower it so that the
mounting bracket tab is inserted into the slot on the
back of the cabinet.
Using the 4 5/16” bolts provided, tighten the manifold
cabinet to the mounting bracket.
Header Installation
Powerex header assemblies, including Liquid x Liquid
bank headers and Emergency Reserve bank header
(liquid only) are sold separately.
Attach the headers to the union on each side of
the manifold control cabinet. Using a level, mark the
placement of mounting brackets while keeping the
header on a horizontal plane.
Remove the U-bolt assemblies from the header
mounting brackets. Position the brackets so that the top
of the bracket is aligned with the bottom of the headers
and is centered between the cylinder connections.
The end bracket should be placed as close to the last
cylinder as possible to provide the most support and
stability.
Mark the mounting hole and install fasteners suitable
for type of wall construction (fasteners not included) .
Fit the U-bolt over the header piping and tighten the
two mounting nuts.
