Installation Instructions
Installing pigtails & attaching
cylinders – LLU models
1.
This photo shows a completed
installation. Note the copper tubing
and unions are installed and
furnished by the installer.
2.
The check valve outlet fittings on
the manifold header bars are CGA
(Compressed Gas Association) gas
specific threads. Each of these
fittings has an integral check valve.
Make sure the 3 digit CGA number
stamped on the outer perimeter of
these fittings matches the CGA
number stamped on the mating
CGA fittings on the pigtails. Attach
the pigtails to the check valve outlet
fittings on the manifold header bars.
3.
Connect the other end of the pigtail
to the “Use” valve mating fitting on
the portable bulk vessel. Open the
use valve (turn counter-clockwise to
open). The pressure building valve
or regulator should be turned on or
opened for all vessels connected to
the manifold (both service and
reserve banks). Allow
approximately 1 hour for the
portable bulk vessel(s) to build
pressure.
4.
Check all cylinder and pigtail
connections for leaks using an
oxygen safe leak test solution (any
bubbles forming around
connections indicate leakage).
5.
Verify that the pressure being
supplied to the manifold cabinet
exceeds the minimum inlet pressure
requirements per the table on page
27.
